However, the more plastics are utilised, the more microplastics are released. This review and analysis article summarises and or­ ganises the knowledge from 211 current related publications published in 2014–2022. The review and analysis explain the kinds of plastics employed in construction and built environment. Fabrics or textiles, fibres and plastics in cementitious systems, paints, tyres and roads are discussed. The entry points of microplastics into the human body are reviewed next, followed by the management of recycled wastes. The important research gaps and possible solutions include using high-strength concretes and surface-hardening agents is suggested to encapsulate the microplastics inside the matrix; DPSIR model analysis can be holistically adopted for each composite; innovative bio-chemical technology like self-healing concrete and bio-degradable plastics can be a viable choice; and social science, law and urban planning can support awareness and comprehension. 1. Introduction 1.1. Definition of microplastics The term “microplastics” was not coined until 1972, when a study evaluating the presence of microscopic fragments of plastic in water used it. These microplastics are fragmented into fine synthetic plastic particles. Microplastics, which were considered to have a particle size distribution (PSD) of 100 nm to 5 mm, are considered environmental hazards (Van Cauwenberghe et al., 2013; Wright et al., 2013; Fok et al., 2020; CONTAM, 2016). Also, Ng et al. (2018) reported another term for fine plastic particles as “nanoplastics,” which is considered contamina­ tion, where their approximate PSD could range from 1 nm to 100 nm. Microplastics can be divided into primary and secondary groups. Primary microplastics are the particle waste products generated throughout the production process (Carpenter et al., 1972). Secondary microplastics are the small debris generated from the degradation of larger plastic materials as a result of mechanical strain, hydrolysis, oxidation and weathering effects from UV light, heat and microorgan­ isms. These factors all contribute to the breakdown of larger plastic materials, which in turn leads to the generation of secondary micro­ plastics (Arthur et al., 2009; Guo et al., 2020). An et al. (2020) stated that the secondary microplastics were the main contributors to the total amount of microplastics found. Despite the fact that Asia is responsible for the greatest amount of plastic production (Liang et al., 2021), microplastics are rapidly increasing worldwide, as shown in Fig. 1. The distribution of micro­ plastics can vary depending on microplastics’ factors and environmental factors. Browne et al. (2011) asserted that there was no correlation be­ tween the presence of microplastics at any location and the average PSD found in samples. To place an emphasis on the environment, the use of microplastics in the building and construction sectors should be iden­ tified as a worldwide concern. A significant body of research on microplastics has been conducted in the realms of marine ecosystems (Arthur et al., 2009; Alimba and Faggio, 2019; Li et al., 2021; Sharma and Chatterjee, 2017), agricultural ecosystems (Zhang et al., 2022; Jin et al., 2022), terrestrial sediments (Xu et al., 2020a; Wong et al., 2020; Sarker et al., 2020), aerated systems (Prata et al., 2022a) and aquatic environments (i.e., drinking water and wastewater) (Pivokonsky et al., 2018; Koelmans et al., 2019; Enfrin et al., 2019). 1.2.

Developments in the Built Environment 15 (2023) 100188 English documents with the final version were determined, as well as note and short survey were excluded. A flowchart of the selection pro­ cess based on the PRISMA model is illustrated in Fig. 2. Some conference papers and papers with no clear methodology or clear effect were excluded. 211 related publications were then reviewed and metaanalysed. The PICO (population, intervention, comparison, and outcome) process was adapted and depicted in Table 1. This paper presents a novel systematic review and analysis of microplastics in construction and built environment domains. This study contributes to the body of knowledge on microplastics in the fields of construction and built environment in four different subject areas: • Categorisation and technical understanding of several types of microplastics • Sources • Routes to the human body • Management of recyclable wastes • Source for other contaminants Additionally, microplastics can be a source of contaminants, which will be discussed. Next, state-of-the-art knowledge based on the current investigations and needs for future studies is summarized and implied. Based on analyses, all pertinent publications have been published in an increasing manner, as illustrated in Fig. 3. The increased number of papers relating to microplastics in building and construction in a few years may indicate a rise in interest and concern. Fig. 4 (Ritchie and Roser, 2023) depicts the geographical distribution of published papers, the substantial growth in the number of articles over time and the quantity of microplastics released annually. From the figure, a higher-GDP country creates a larger number of publications, but no relationship exists between the number of publications and the amount of production. The data on the quantity of microplastics released annually were retrieved from a report by Boucher and Friot (2017). The majority of studies were published in China, the United States, the United Kingdom and Germany. For several locations, such as Africa, the Middle East and Southeast Asia, research is limited. Chen et al. (2020) adopted a regression model to predict the regional distribution of microplastic pollution in freshwater globally. The results indicated that the degree of pollution caused by microplastics was highest in Asia, followed by Europe and South America. The amount of pollution that was present in developed nations was noticeably smaller than that in emerging regions. The level of human activity was the primary factor that determined whether urban regions or rural areas had higher levels of freshwater contamination. Although the results were focused on microplastics in aquatic bodies, construction and building sites on land can be inferred. The absence of location-based research can be addressed in some terrestrial regions of the world. Fig. 1. Actual and projected global plastic production. microplastics can induce immunotoxicity, cytotoxicity and reproductive consequences in humans (Stock et al., 2021), which leads to increased worries about our long-term health. Plastic pollution that builds up in an area of the environment is called “poorly reversible” if the area’s natural mineralisation processes are slow and it is unlikely that engineers can resolve the issue. For these reasons, plastics are currently considered a major global problem (MacLeod et al., 2021). Over the last few decades, the issue of the contamination of eco­ systems by microplastics has garnered increasing attention, with the earliest investigations occurring in the marine ecosystem (Andrady, 2011). Hale et al. (2020) asserted that the vast majority of plastics have their first uses and are afterwards disposed of on land. Li et al. (2016) estimated that 80% of the microplastic contamination seen in marine environments originated from land. However, a review regarding microplastics in the building and construction industry is lacking, and the need for comprehensive study should be performed so that the knowledge based on related publications can be categorised and summarized. The building and construction industry is one of the backbone ac­ tivities for the development of every nation. Nonetheless, microplastics in the construction and built environment have rarely been focused on, although these industries are responsible for 14% of yearly plastic output (Schwarz et al., 2019). Yet, this large volume of microplastic releases from these sectors is not clearly validated (Gaylarde et al., 2021). An U.S. Environmental Protection Agency (EPA) study pro­ gramme found that the production process for microplastics in the construction sector might be the most dangerous activity overall (Mahon et al., 2014). One review article published by Gaylarde et al. (2021) focused only on paint fragments, and another review article published by Yuk et al. (2022) concentrated on microplastic air pollution from the deterioration of building materials. Recent researchers have reviewed a few publications. Several studies have pointed to the viability of using a material based on cement to encapsulate microplastics (Signorini et al., 2022; Malchiodi et al., 2022a; Sharma et al., 2021). The findings of this review provide information that may be used in an all-encompassing manner to address the environmental challenges related to micro­ plastics that we are currently confronting. 3. Categorisation of common plastics used in construction and built environment Many plastics have been extensively utilised in construction and built envieroment. Polypropylene (PP), polyethylene (PE) and polyvinyl chloride (PVC), which together account for approximately 60% of the world’s total output of thermoplastics, are the three main producers of thermoplastics (Hiemenz and Lodge, 2007). Polyethylene terephthalate (PET) is another material that may be found in consumer products, packaging and water bottles. The construction and building industries make extensive use of these synthetic polymers, which may be found in various applications, such as microfibres, fibre reinforcement, microbeads, sheet insulation, paints, plastic pipes and claddings (Stock et al., 2021). Fig. 5 presents the scanning electron microscope (SEM) images of these four typical microplastics at various magnification levels: PP, PE, PVC and other plastics (adapted from (Stock et al., 2021)). 2. Review methodology The research was done using Scopus and Google Scholar databases published from 2014 to 2022 and searched in December 2022. The terms pertaining to microplastics, construction, building, built environment and waste were found in the title, abstract, and keyword sections. Only 2 L. Prasittisopin et al.

Flow chart of the selection process. connectors, geotextiles, carpets, furniture fabric, plastering mortar and microfibres that are incorporated into concrete to make the material more robust and long-lasting. Plastering mortar contains a few milli­ metres of short PP fibre to reduce microcracking when exposed to high temperatures, low humidity and direct sunlight. By contrast, PP fibre in concrete typically employs longer PP fibre in centimetres to increase the product’s flexibility and decrease macrocracks (Stock et al., 2021; Hie­ menz and Lodge, 2007).

PE PE is one of the three most made polymers due to its great chemical resistance, fatigue resistance and wear resistance. It was first created in the 1930s by scientists in the United Kingdom, and widespread com­ mercial use of the material did not start until after World War II. Addition or radical polymerisation processes are used to make this commodity thermoplastic. Its early applications were in the production of films and mould-based goods. The macromolecular structure of PE is shown in Fig. 5. On the basis of density or molecular weight, PE may be broken down into three distinct forms: low-density PE (LDPE), mediumdensity PE (MDPE) and high-density PE (HDPE). The other types may be linear LDPE and ultrahigh-molecular-weight PE. Numerous applications of PE plastics have been found in concrete curing sheets, covering sheets, mulching nets and man-made glass (Szlachetka et al., 2021). 3.1. PP PP is brittle, hard and crystalline. It is constructed using propene (or propylene), which is a monomer. In comparison with other types of commodity plastics, this linear hydrocarbon resin has the lowest weight of any polymers. Additives may significantly improve the properties of PP, which can be purchased as either a homopolymer or a copolymer. It was made accessible for commercial use in the latter half of the 1950s. It is considered a commodity plastic in modern times. The fact that it comes in diverse forms, is very inexpensive and has easy access to a huge supply of feedstock all contribute to its widespread availability. Its chemical structure is shown in Fig. 5. In the realms of construction and building, PP is used extensively in various applications, including joint 3 L. Prasittisopin et al.

As a result, renovation is required, and the interior flexible PVC is replaced every 10 years. PVC, frequently, the definition of PVC plastic is that it usually con­ tains 50% or more vinyl chloride units by weight. The chlorination of PE generates PVC, which results in the production of polymers that are structurally comparable to one another but possess distinctive properties (Hiemenz and Lodge, 2007). The chemical structure of PVC is illustrated in Fig. 5. Table 2 presents an overview of the primary physical charac­ teristics of PP, PE and PVC (Stock et al., 2021; Hiemenz and Lodge, 2007; Szlachetka et al., 2021; Miliute-Plepiene et al., 2021; Daniels, 2009). PVC is the third-largest thermoplastic substance by volume in the world, after PE and PP. The typical length of homopolymers is between 400 and 1000 units. PVC is a white, brittle, solid substance that comes in powder or granule form. It is replacing traditional construction mate­ rials, such as wood, metal, concrete, rubber and ceramic, in various applications due to its diverse qualities, including lightweight, dura­ bility, low cost and easy processability. PVC is rigid by nature, but adding plasticiser can make it flexible. It is a cost-effective and flexible thermoplastic polymer used extensively in the building and construction sectors to manufacture door and window profiles, pipes (drinking and wastewater), wire and cable insulation, medical equipment, ceiling tiles, flooring, furniture, coatings and wood-plastic composites (Mil­ iute-Plepiene et al., 2021). For pipes, rigid PVC pipes may be readily cut (with a hacksaw or tube cutter) and installed and are frequently used to replace broken parts of ancient cast iron waste pipes. Their segments can be joined mechanically (using plastic pressure fittings that can be removed later) or permanently (using a specialised chemical solvent). For flexible PVC, it is an important material in buildings and construc­ tion, used for cable insulations, floor covers, etc. In 2018, more than 50% of flexible PVC was utilised in building and construction industries in the European region (Daniels, 2009). These PVC products have a life expectancy of over ten years, but this service life is short and does not 3.4. Other plastics (polystyrene, polyurethane, polyethylene terephthalate, polyacrylonitrile, polyvinyl alcohol) Several other polymers, such as PS, PU, PET, PAN and PVA, are utilised in building and construction applications. These polymers are used in smaller quantities compared with PP, PE and PVC due to their higher cost and fewer uses. Specifically, PS has been extensively utilised as thermal and acoustic insulation and lightweight structural concrete (Prasittisopin et al., 2022). PU has been extensively used as an insulating foam for roofs, attics, facades, basements, cellars, floors, interior wall panels, spaces between levels, inner sections, walls and ceilings. PET is typically utilised as fibre reinforcement in concrete, carpet and 4 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 Fig. 5.

PAN is used for outdoor fabrics, including tents, boat sails, carpets and ropes, because of its great resilience to solar damage and as a reinforcement for cementitious materials (Wright et al., 2020). PVA, due to its mild surfactant feature and viscoelastic properties, can be utilised as a surface treatment agent for aggregates and supplementary cementing materials and as fibre reinforcement (Thong et al., 2016; Prasittisopin and Trejo, 2018). fibre reinforcement in concrete, paint, plastic beads and insulation sheet, are reviewed. 4.1. Fabrics or textiles Fabrics and textiles have long been used in the building and con­ struction industries, both temporarily and permanently. Many applica­ tions in buildings entail bedding and sleeping bags, carpets, curtains and furniture. Choi et al. (2021) investigated different washing techniques in polyester fabric construction for minimizing the release of microplastics. The authors concluded that the release of microplastics was influenced by temperature and time. Reducing the temperature and time could lower the physical force, leading to a reduction in the amount of microplastic released. Moreover, using filtration devices in the washing 4. Sources of microplastics in construction and built environment Several sources of microplastics utilised in the construction and built environment sectors, including fabric or textile in construction sites, 5 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 process could collect the microplastics effectively. Roos et al. (2017) examined several washing processes for polyester fabrics. The authors revealed that microplastics could be released after washing, with levels varying by up to 400 times. Fabric construction (woven, knit and nonwoven), yarn type (twist, evenness, hairiness and number of fibres), processing history (spinning, knitting or weaving, scouring, bleaching, dying, finishing and drying processes) and fibre physicochemical prop­ erties can all influence the amount of microplastic fibre generated dur­ ing fabric washing (Hernandez et al., 2017). In essence, for fabric construction, the washing operations are the primary source of micro­ plastics that are produced. Fig. 6 illustrates the uses of fabric or textile products in building and construction applications. Microplastic shedding from textiles can be another source of microplastics. Jönsson et al. (2018) assessed the releases of micro­ plastics from shedding polyester textiles and asserted that microplastics can be released into the environment either from the fabric’s surface or from the cut edge of the fabric. The researchers also found that the measurements that have been done so far to determine the shedding of microplastics from fabrics have indicated a wide range when measured by the filter analysis method. The total number of particles shed by comparable clothes ranges from 120 to 728,289. To achieve their objective, a novel technique was created. The research described the final method and the work done to minimise error sources and, conse­ quently, the standard deviation of the results through the selection of material samples, equipment and procedures for sample preparation, washing, filtering the washing water and analysing shed microplastics. In addition, the shedding of synthetic fibres, including acrylic, nylon and polyester, from textile carpets was investigated by Carney Almroth et al. (Carney et al., 2018). Their results indicated that the fabrics made of nylon, acrylic and PET all shed fibres, but there was no noticeable dif­ ference between the three types. Significant quantities of fibres were also released during the production of the textiles due to loose manufacturing. The release of microplastics can vary depending on the fabric patterns and manufacturing techniques employed. Furthermore, architectural constructions, such as marquees, mem­ branes, awnings, double wall spacers and pneumatic structures, have garnered significant interest in recent times. Synthetic textiles are good candidates to be used in the construction of the majority of the roof components of any temporary, semipermanent or public superstructure. In these types of applications, the synthetic fabrics that are used should be lightweight, robust, resistant to rot, moisture-proof and unaffected by UV sunlight (Horrocks and Anand, 2000). Chen et al. (2021) asserted that, currently in China, mulching construction land with dust-proof nets is legally required to prevent and regulate the pollution caused by fine particulate matter. Fine particulate matter could pollute the envi­ ronment by contaminating microplastics. The findings also indicated that the studied mulched regions contained a substantial number of large particles with a size greater than 1000 μm (50%). PE (which made up greater than 50% of the microplastic polymers) and PP (which made up 41% of the microplastic polymers) were the most common varieties. The buildup of microplastics in soil that has been mulched by dust-proof netting at a building site is, on average, almost six times higher than that at an unmulched site. A quantity of microplastics of this scale has the potential to trigger a feedback loop of adverse environmental conse­ quences. To preserve human health, in addition to the soil and envi­ ronment as a whole, recommendations were offered to decision-makers for the revision of appropriate legislation and policies. For example, the appropriate architectural constructions using synthetic textiles will be Fig. 6. Applications of fabric and textile products in the construction and built environment sectors. 6 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 regulated by implementing only temporary construction, applying limited numbers of reuses and having controlled serviceability in a shorter period, unlike nontextile constructions. Other applications in construction reported to be sources of micro­ plastics are the use of scaffold netting on construction sites and a syn­ thetic grass sheet that covers the land (Mehmood and Peng, 2022). The plastic commonly used is PE. These PE products are often of lower quality and made from recycled materials, which make them more prone to destruction. In addition, because these products are consistently exposed to the outdoors, there is a substantial possibility that PE might fracture and that the atmosphere would be contaminated. This could lead to the hazardous utilisation of these products in excessive amounts or without proper oversight. Lastly, even in areas with fewer human activities, such as the Tibetan Plateau, microplastics from plastic tents have been found in rural hill­ side tourist areas (Jiang et al., 2019). Plastics have largely taken the place of more conventional building materials, such as animal skins and natural fibres, in the construction of simple forms of temporary shelter, including tents. Microplastics could also come from fragments and fibres that were shed from plastic tents. As a result, a significant amount of the wastewater and solid waste that were collected did not undergo the appropriate treatment before being released into the river. In addition, the dispersed and frequent mobility of herders who used plastic tents has made it impossible to prevent and regulate microplastic contamination. This has led to an increase in the severity of the problem. The immense size of the Tibetan Plateau, the lengthy travels of many of its residents and the generally problematic transportation have all proven to be ob­ stacles in the way of preventing and controlling the pollution caused by microplastics in this region, particularly in rural regions. construction of prefabricated structures, which is anticipated to result in efficiencies in the near future regarding both the use of resources and the influence on the environment (Yan et al., 2000). These modern con­ structions and buildings make extensive use of plastic in increasing amounts. Plastic beads are one of the key applications used in cementitious materials to replace aggregates, with the objectives of reducing static weight and enhancing thermal and acoustic resistance. Expanded PS (EPS) and expanded PP beads are typically added as a replacement for fine aggregates (Hong et al., 2016; Chen et al., 2015; Su et al., 2022). Zaragoza-Benzal et al. (2022) used a mixed solvent for dissolving recy­ cled EPS beads and added it to plasters in 2023. Although the resulting products offered excellent performance, this innovative method in fact accelerated microplastic emissions. In the construction sector, there are several research projects that have an emphasis on substituting either virgin EPS beads or recycled EPS beads to decrease waste and promote sustainability. Despite this, minimal work has been done about the release of microplastics. Consequently, there is a significant hole that must be filled by future research and development. In addition, it is common knowledge that the EPS bead itself may serve as a significant ignition source for residential and commercial structures. As a result, a significant amount of research has concentrated on the use of fire re­ tardants, which may also be discharged concomitantly with the release of microplastics. The fracturing of EPS beads results in the release of microplastics, which causes a significant increase in the extent of dam­ age. Jang et al. (2017) mentioned that hexabromocyclododecane was also found in high concentrations in the EPS debris that was collected from the coastal regions of Asia and the Pacific, which suggests that HBCD pollution caused by EPS debris is a widespread environmental problem across the world. Some also used methylene diphenyl diiso­ cyanate, melamine cyanurate and aluminium hydroxide as chemicals for flame retarders in EPS concrete systems (Bhoite et al., 2021; Lee et al., 2022). In more recent years, synthetic fibres have been employed in the formulas of 3D printing for buildings to develop attributes that are more flexible and resistant to cracking and to reduce the amount of shrinkage that occurs. This development in building technology is gaining considerable attention from scholars all around the world. Fibres, such as PP, PE and PVA, with various morphologies and sizes, are basically employed in small amounts (Farina et al., 2016; Pham et al., 2022; Xiao et al., 2021; Sukontasukkul et al., 2022). Regarding more recent appli­ cations, 3D-printed concrete is being constructed into artificial coral reefs because the 3D printing material can construct artificial coral skeletons based on natural calcium-based materials, which will accel­ erate the pace at which real coral parts will mature and the process of transplanting reefs, all while keeping nursery expenditures to a mini­ mum (Santos et al., 2023; Yoris-Nobile et al., 2023; Albalawi et al., 2021). Yoris et al. (Yoris-Nobile et al., 2023) mentioned that the fabri­ cation of 3D-printed artificial coral reefs can be viable in terms of onsite, large-scale production. Synthetic fibres are required in their formation. Nevertheless, the use of a 3D printer in the production of an artificial coral reef is a direct and expeditious method of dispersing microplastic particles into the surrounding water. Some researchers have investigated the use of waste plastic products, such as fishing net, rayon and PVC, in cementitious systems (Pae et al., 2022; Mahmood and Kockal, 2022; Malchiodi et al., 2022b; dos Santos et al., 2022). Malchiodi et al. (2022b) began by incorporating up to 4% of the microplastics that the team had gathered from the air-pumping and air-filtering systems of a cotton textile finishing facility in Italy into concrete in an effort to enhance the quality of the concrete. Their performance was commendable. However, these concrete products will likely emit microplastics in the future due to erosion and demolition. Another limitation was reported by Dorigato (2021): the recycling of waste fibre in the construction sector remains a significant obstacle due to technological and economic concerns that are preventing further advancement. 4.2. Fibers and plastics in the cementitious systems Concrete is a material that is utilised on earth on a greater scale than any other substance besides water. Their material formulation has un­ dergone extensive development and is continuing to do so in the hopes of lowering the number of practical challenges and raising the level of functioning. For instance, fibre-reinforced cementitious composites have been widely introduced into cementitious materials to enhance their performance characteristics in terms of mechanical features and durability (Malchiodi et al., 2022a; Monazami and Gupta, 2021; Pae et al., 2022; Prasittisopin and Trejo, 2013a; Teng et al., 2018). The use of various types of fibres, such as PVA, polyolefin and PAN, has been evaluated to improve damping, tensile strength, flexural strength, toughness and dimensional stability characteristics (Jiang et al., 2019; Kujawa et al., 2021; Long et al., 2021). Thong et al. (2016) reviewed the use of PVA in cement composites and stated that PVA fibres had a ho­ mogenous dispersion in the cementitious matrix and that considerable amounts of these fibres were well attached to the matrix. This was done in the context of microscale enhancement. This might be explained by the hydrophilic nature of the PVA fibres, as well as their structure, which was rough on the surface. Consequently, a strong link with the cemen­ titious matrix was created, leading to an improvement in the interfacial transition zone region. Although only small amounts of polymers are required to improve the quality of products on both micro- and mac­ roscales, the use of these synthetic polymers will ultimately result in the release of microplastics due to the nature of their incorporation. Sandwiched concrete panels with polymeric materials are an effi­ cient and lightweight building material that works as a load-bearing and insulating element. These panels, together with plastic connectors, may be made with either natural or synthetic polymers, such as EPS or PU sheet (Chowdhury et al., 2013). The sandwiched concrete panels offer a number of benefits, including a reduction in the amount of time spent building dwellings, the withstanding of seismic forces and savings in material costs. In many countries, such as China, the USA, Japan and Europe, these sandwiched concrete panels are likely applied because the governments of such countries are currently actively pushing the 7 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 4.3. Paints that the use of these items by consumers is frequently accompanied by considerable emissions of polymers, the categories of paint, lacquer and dyes have been assigned a high priority score. The matrices of paint are composed of polymers with concentrations ranging from 14% to 30%, and examples of these polymers are epoxy, acrylic and alkyd. Further study is required to determine whether these and other components of paint should be categorised as microplastics. Consumers, in contrast to professionals in the construction business who use these goods on a regular basis, frequently lack the equipment necessary for the correct disposal of paint waste, brushes, rinse solutions and dust. Compared with professional practices, the construction industry is more organised when it comes to the proper disposal of waste glue and paint, as well as the cleaning of brushes. Sanding old coats of paint or exposing buildings to general wear and tear during renovations can also result in the release of plastic particles into the atmosphere. This kind of emission can sometimes take up a significant amount of space. The dimensions of the dust that is created by sanding or wear range from 50 nm to 2–3 μm (Koponen et al., 2009). There are few to no alternatives to using microplastics in paint currently available. Disseminating knowledge regarding dust-free working practices, such as cleaning it up, might contribute to an even greater reduction in emissions. Within the in­ dustry, there is an awareness of careful working procedures as well as paints and glues that are less harmful to the environment. The latter element, however, is more related to solvents than it is to the possibility of the existence of microplastics. Paints have been widely used in the building and construction in­ dustries. Their formulations contain PU, PS, polyesters, polyacrylates, alkyls and epoxies. Building coatings, a class of paints used in building and construction work, are also a source of microplastic. Microplastics are incorporated into paint to impart a surface effect (such as a matte finish), improve the appearance of the colour, lessen the paint’s density and make it easier to apply, make the paint harder and more resistant to scratching or provide a glitter or decorative effect, for instance (Lassen et al., 2012). Recent research that investigated the release of micro­ plastics from paints and coatings suggested that paints contribute more to the microplastics in the environment than textiles do (Olatunji, 2022; Lassen et al., 2015). The methods of washing, construction styles (in the event that microplastics are released from painted buildings and struc­ tures), the age of items (such as tyres), the environment and weather conditions are all factors that might influence the rate at which micro­ plastics are released. Microspheres that are included in the formulation of paint typically have a diameter of anywhere from a few to hundreds of microns, with the only exception of glittering particles, which may have a diameter of anywhere from a few millimetres to a few centimetres (OECD Emission Scenario Document on, 2009). These formulas are especially helpful for anti-slip applications, road markings, outdoor and indoor structural paints, swimming pools and heavy-duty flooring and tiles. These uses involve significant wear, and as a result, the systems have the potential to cause the creation and release of fragments into the surrounding environment. The loss of fragments can also take place after the paint has been weathered (mostly by UV irradiation) or after the underlying layer has been weathered (e.g., following the formation of rust on metal surfaces), or it might take place during maintenance (e.g., sanding of the surface to be repainted). According to Hann et al. (2018a), building decorative paints account for 4.2 million tons a year, with about 73% for the interior segment and approximately 27% for the exterior segment. Gaylarde et al. (Mahon et al., 2014) asserted that the release of microplastics from building paints is mostly due to the breakdown caused by UV irradiation. The discussion by Gaylarde et al. (Mahon et al., 2014) seems to be specifically for the exterior segment. The Organization for Economic Co-operation and Development (OECD) (OECD Emission Scenario Document on, 2009) has estimated that a total of 6% of paint is lost over the course of its lifetime: 1.8% of the paint is lost during painting, 1% is lost due to weathering, and 3.2% is lost during removal. This loss could account for 21,100–34,900 tons annually for the European Union, the majority of which is absorbed by soil, but some of it (2000–8000 tons annually) is released into the waterbody (Hann et al., 2018a). Zohuriaan-Mehr and Omidian (2000) also reported that the proportion of nonfibrous microplastics made up of polymerised petroleum resin was 9%. In the manufacture of varnish and building paints, as well as in the creation of rubber tyres and road paint, this polymer is frequently combined with other sorts of resin. In a broader sense, the urban environment represents a rich and varied indirect source of paint particulate. Paint particles are generated when decorative, anticorrosive or safety paints on private and public buildings, road surfaces and municipal structures and street furniture undergo natural deterioration or are deliberately disturbed during maintenance, repair or removal (Turner, 2021). In recent years, devel­ opment in metropolitan areas has been widely implemented on existing building sites that require destruction. These sites have been mostly used for new building construction as well. This allows for the demolition of numerous painted internal and external components, resulting in the release of a significant amount of microplastic particles. Accordingly, each area or country should have a viable strategy for the management of debris from building and demolition activities (Kawecki and Nowack, 2019). The existence of microplastics in paint is a topic about which very little is known, although its priority need was ranked third, after packing material and litter (Verschoor et al., 2016; Galafassi et al., 2019). Given 4.4. Tyres and roads The impact of roads and traffic on the natural environment sur­ rounding human populations has been a subject of scientific inquiry. The research outcomes indicate that pollution exerts a harmful impact not only on terrestrial ecosystems but also on aquatic environments. Road pollution is frequently characterised by elevated levels of particles, which comprise mineral particles such as quartz and feldspar, as well as micro- and nanoparticles that arise from the wear and tear of tyres and road surfaces. Tyre and road wear particles have garnered significant research attention in recent times. The surge in research attention can be ascribed to the escalating interest in pollution caused by micro- and nanoparticle substances. The presence of synthetic rubber can be attributed to the composition of particular road surfaces and tyres. Tyre wear particles are regarded as the primary microplastic source, followed by abrasion particles from road markings and road wear par­ ticles. Polymer-modified bitumen represents the second and third sources of microplastic particles entering the marine environment from land. Roads and traffic are estimated to be the largest source of micro­ plastic particles entering the marine environment from land (Rødland, 2022). In 2016, rubber accounted for 26.9 million tons, of which 12.6 million tons were natural rubber and 15 million tons were synthetic rubber (Xu et al., 2020b). Tyres used in automobiles are one of the most important contributors to rubber emissions. Tyres generate significant amounts of fine particles and waste ranging in size from nanometres to micrometres. It has been completely disregarded that tyres serve as a covert source for microplastics, yet estimations have established that between 26% and 74% of microplastics are obtained from the rubber that is found in tyres (Andersson-Sköld et al., 2020). The Swedish National Road and Transport Research Institute recently reviewed studies from 2020 and reported that polymers, as well as various chemical additives and fillers, were what made up both tyres and road markings (Burghardt et al., 2022). Elastomer is a type of thermoset polymer that is used in the production of tyres. Thermo­ plastics, thermosets, thermoplastic elastomers or elastomers are present in the polymers that make up road markings and polymer-modified bitumen. However, there is currently limited, if any, knowledge about the extent to which these substances are released from microplastics. This is despite the fact that some of the chemicals used in the production of tyres, road marking products and polymer-modified bitumen are 8 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 hazardous to human health and the environment. Besides, road mark­ ings were not identified as substantial contributors to the pollution caused by microplastics (Hossain et al., 2021). Although a large quantity of microplastics from the abrasion of tyres was found, the proportion of particles carried to water receivers is currently unclear due to the lack of data on the microplastic contents of stormwater from roadways. It is also unclear how much of the microplastics are permanently deposited in the ground next to the road. The same is valid for artificial turfs, in which between 2300 and 3900 tons of materials are lost annually, but there are no data on the quantity that is carried to the ocean (Tamis et al., 2021). One recent study determined the presence of microplastic in a part of Gothenburg, Sweden, that was being rebuilt. The authors indicated that sweeping the streets was an effective and promising way to stop microplastic from spreading (Järlskog et al., 2020, 2021). Table 3 shows an overview of microplastics in the building and construction industries. which was roughly 10 times greater than the abundance of microplastics in stations that were located further away. The characteristics of the microplastics, such as their sizes, morphologies and colours, were clus­ tered in such a way that the three stations that were located in close proximity to the plant belonged to one group, while the stations that were farther away belonged to another group (Fig. 7). According to the results of their research, uncommon microbial species, also known as “rare taxa,” had a positive correlation with microplastics. It was discovered that this shift in rare taxa profiles (such as decomposition processes and resistance to microbial decay) altered the human skin and nasal microbiome (Miranda et al., 2020). The existence of rare taxa is evidence that humans are likely exposed to an increased quantity of microplastics in this area. This phenomenon has also been observed in dam and weir construction (Zhang et al., 2017). The next type of building that has gained popularity is known as “rapid construction,” particularly in China. This building technology has also been utilised by a large number of offshore wind farms, such as those in the Yellow Sea in China (Wang et al., 2018). In 2016, the re­ searchers conducted a study to determine the degree of microplastic contamination at an offshore wind farm in the Yellow Sea in China. The degree of microplastic contamination in the region we studied was comparable to that found in coastal locations all over the world, but to a somewhat greater extent. The hydrodynamic impact, which was influ­ enced by human activities, was shown to be the primary factor deter­ mining the leaching of microplastics in the intertidal zones of the local region (Fischer et al., 2016). In addition, stormwater treatment wetlands are one of the most important strategies for dealing with the runoff that is caused by roads (Vymazal, 2011). The discovery of synthetic rubber microplastics in stormwater provides more evidence that discarded tyres can be a source of microplastic contamination (Ziajahromi et al., 2020). Road runoff is expected to be a significant contributor to this problem. The fact that the water and sediment samples did not contain any microplastics that possessed the same properties and polymer composition as the con­ struction material for the floating wetland suggests that the micro­ plastics that were found in the water and sediment did not originate from the material that was used to construct the floating wetland. Long et al. (2022) investigated the stormwater treatment wetland in 5. Routes of microplastics from construction and built environment exposed to humans Due to the fact that microplastics are very small particles that are found in land and marine settings, these particles are easily eaten by any species. An accumulation of microplastics can have a negative effect on an aquatic organism’s tissues, organs and digestive tracts, as well as on plants and humans (Van Cauwenberghe et al., 2015; Brame et al., 2021; Khalid et al., 2020). This review focuses solely on the detrimental effects that the use of microplastics in construction and built environment ac­ tivities can have on humans. The release and absorption of microplastics by humans are primarily attributed to two significant mechanisms, namely leaching and airborne dispersion. 5.1. Leaching process to human intakes One of the routes through which microplastics from land might make their way into marine systems is the leaching process. The development and construction that take place in close proximity to coastal regions are major sources of microplastics, which can rapidly seep into the water. Other human activities that can cause the release of microplastics into the water have received inadequate attention. The flow of microplastics into coastal areas has been documented by a number of structures and construction projects, including nuclear power stations, dam construc­ tion, offshore wind farms and stormwater treatment in wetland areas. For coastal nuclear power plants, Yu et al. (2020) asserted that more than half of the world’s nuclear power plants are located along coast­ lines; moreover, in China, every single one of the country’s nuclear power stations is situated in coastal regions. Wang et al. (2022) analysed the sediments at 20 different sites located close to a nuclear power fa­ cility in northeast China that is presently under construction. The au­ thors noted that the average abundance of microplastics in three stations that were located close to the nuclear power plant was 0.33 items/g, Table 3 Overview of microplastics in the construction and built environment industries.

Developments in the Built Environment 15 (2023) 100188 Changsha, China and discussed how the relationship between the plants and the sediment in the created wetland was important for the micro­ plastic removal efficiency. When the features of the distribution of microplastics in urban stormwater treatment wetlands were taken into account, rural stormwater treatment wetlands were found to have fewer microplastics, lower removal efficiencies and a greater proportion of finer microplastics. The efficiency with which rural stormwater treat­ ment wetlands remove microplastics is something that still has to be improved. Li et al. (2022) studied the amount of microplastics released in the Yangtze River Basin and concluded that seasons affected the load of microplastics, with October having the highest load. Once it entered the river, the leaching of microplastics from nonpoint sources was reduced by 26%. The amount of microplastic leaching might then decrease by up to 81% once the microplastics reached the ocean. It seems that this ratio arises from a solitary location. Conducting multiple research projects in diverse locations and environments is necessary to determine the ulti­ mate effects of microplastic leaching from construction and built environment. this study demonstrated that indoor environments contained excessive amounts of microplastics, which may induce a substantial exposure risk for various age groups. Using a proxy-based methodology, the Swiss Federal Statistical Of­ fice’s dataset on new building emissions of airborne microplastics revealed that the majority of the microplastics came from EPS and a small amount from PS (Kawecki and Nowack, 2020a). The Swiss Plateau, where the majority of human activities and new construction projects were concentrated in Switzerland and which extended from Lake Constance in the northeast to Lake Geneva in the southwest, was where a significant portion of emissions were produced. Geographical significance thus pertains to the dispersion of airborne microplastics. A comparison of indoor and outdoor air quality showed that the concentrations of suspended particles varied from 0.4 particles per m3 to 60 particles per m3 for indoor air and from 0 to 2 particles per m3 for outdoor air. Microplastics permeated the air, with indoor air containing twice as much as outdoor air (Gaston et al., 2020; Prata et al., 2022b). Adequate air ventilation is necessary in closed or semi-closed spaces to prevent the occurrence of significant concentrations of microplastics. Similarly, Dris et al. (2017) proved that indoor air contained more airborne microplastics than outdoor air. Torres-Agullo et al. (2022) also argued that this issue is severe because interior surroundings are sig­ nificant, given that people spend 90% of their time indoors. There have also been reports of finding microplastics not only inside buildings and workplaces but also on buses and subway trains. According to the information that is currently available, inhalation is one of the main ways in which people become exposed to microplastics (Paulpandian, 2021). There is limited information on the dangers of inhalation and airborne microplastics in various indoor environments (Torres-Agullo et al., 2022). To determine their relative roles as path­ ways, further research is necessary. Therefore, both indoor and outdoor air should be considered to fully comprehend the dynamics of micro­ plastic in urban surroundings. 5.2. Airborne pollutants Airborne microplastic is a growing concern for human exposure and environmental contamination. In accordance with the volume of the emission and the potential for widespread release of the emission into the environment, mitigation measures for airborne microplastic dust emissions are prioritised in the construction industry (Verschoor et al., 2014). Ingestion, skin contact and inhalation are the three main ways through which microplastics could enter the body. Firstly, the micro­ plastics that are inhaled come from urban dust and can be made up of rubber tyres, dust from construction and man-made textiles. Secondly, microplastics would be ingested because microplastics are widely distributed in the food chain and water supplies. The epidermal mem­ brane is too thin to allow microplastics to pass through, but the micro­ plastics might still enter through cuts, sweat glands or hair follicles. Despite the fact that microplastics enter the human body through all three of these routes, environmental and seafood particles still pose the greatest danger of absolute exposure (Yee et al., 2021). Due to excessive traffic, tyre and road wear particles and urban reconstruction, microplastics are discharged in large quantities. More­ over, airborne microplastic dust is produced during significant building, bridge and road reconstruction projects. The findings by Järlskog et al. (2021) demonstrated that street sweeping effectively inhibited the spread of pollutants by gathering significant amounts of dirty materials from the extensive construction, renovation and reconstruction projects of road tunnels, bridges, roads and buildings. In Ningbo, a megacity on China’s east coast, Xu et al. (2020b) examined the connection between urban factors and freshwater microplastic pollution near construction sites along an urban river channel. The urban region of Ningbo, including the Fenghua River, was compared with comparable mea­ surements due to the city’s growing population. This study considered regional urban growth, illuminating some of the key variables influ­ encing urban microplastic pollution levels. These controls on micro­ plastic dust in urban areas will also give Chinese cities new perspectives on how to handle the spread and emission of other anthropogenic pol­ lutants in the future. In Iran, Dehghani et al. (2017) determined the indoor and outdoor conditions of buildings in the Tehran metropolis, and Kashfi et al. (2022) considered them in Bushehr and Shiraz cities. Microplastic particles are ingested by children and adults during out­ door activities and in workplaces, with large abundances of micro­ plastics being considered to induce acute exposure. Accordingly, management measures are needed, given that street dust has the po­ tential to be a significant source of microplastic contamination in metropolitan areas. More recently, Kashfi et al. (2022) stated that in­ fants in kindergartens and mosques had a significant daily intake of microplastics from indoor dust ingestion and inhalation. The findings of 6. Recycled waste management in construction and built environment The advocacy of environmental management and the goal of sus­ tainable development have put pressure on all businesses, including those in the construction and built environment sectors, to adopt appropriate environmental protection practices like waste management. Although many researchers have investigated the use of wastes, such as plastic, in the construction process in an effort to reduce waste and in­ crease sustainability, construction is not an environmentally-friendly activity by nature. A successful approach to reducing plastic waste by adding it to concrete as agglomerates is a huge implementation into practices (He et al., 2022; Poonyakan et al., 2018; Adamu et al., 2021). However, one solution for resolving the problem from the tremendous amount of plastic wastes generated could bring another serious problem of leaching of microplastics. The unknown part of this area is huge and needs prompt investigation. In construction and building goods, such as street furniture, roof and floor coverings, piling, PVC windows, wood-plastic composites, asphalt, noise barriers, cable ducting and pipe, panels, cladding, insulation foam and man-made soil, that are specif­ ically made for using recycled plastic, plastic can be recycled and repurposed (Lai et al., 2016). To improve strength, durability, impact resistance and aesthetics, technology is being developed that will allow construction materials to gradually include recycled plastic constituents. Recycling can be an efficient method for managing plastic waste and promoting the circular economy. One potential application for recycled plastic is as a soil amendment or mulch in the soil. When recycled plastic is used as a mulch in soil, it can help suppress weeds by physically preventing light from reaching the soil, thereby preventing weed seeds from germinating (Lamont, 2017; Lalitha et al., 2010). Plastic mulch can also help retain soil moisture by reducing evaporation and slowing the decomposition of organic matter, which releases moisture back into the 10 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 soil. In addition, plastic mulch can regulate soil temperature by acting as an insulator and maintaining a more consistent temperature. Using recycled plastic as mulch could also benefit the environment by reducing the need for synthetic fertilisers. This is due to the fact that plastic mulch can aid in slowing the release of nutrients from organic matter in the soil, thereby providing a source of nutrients with a slow release for plants. However, using plastic mulch is a direct way of introducing microplastics into soil, which can cause problems for human health in the long run (Khalid et al., 2020). Recycled plastic can be used to construct erosion-controlling barriers or blankets for slopes and other areas prone to erosion (Cetin, 2015; Devipriya et al., 2022). These plastic barriers or blankets can be anchored to the ground with stakes or other anchors. The plastic ma­ terial aids in keeping soil in place and reduces erosion. A benefit of using recycled plastic for erosion control is that it can be an effective method for controlling erosion in diverse soil and terrain types. In addition to being relatively inexpensive compared with other erosion control mea­ sures, it is also simple to install and remove. However, recycled plastic may not be aesthetically pleasing in certain settings, and it may not be appropriate for use in all types of soil or terrain. Recycled plastic can be used to create drainage systems in soil to assist with water management (Bolden et al., 2013; Cascone and Gagliano, 2022; Omay et al., 1997). This can be done by creating channels or trenches in the soil and filling them with recycled plastic. One may argue that although this solution can be successful in recycling plastics, it is also a direct route to landfill plastics. Recycled plastics are believed to typically degrade at a faster pace than virgin plastics, and this solution seemingly even augments the rate of microplastic leaching into nature. Plastics also aid in directing water away from an area and can prevent waterlogging and other types of soil degradation. A benefit of using recycled plastic for drainage systems is that it can be an effective means of managing excess water in soil. However, the installation may be labour-intensive, and ongoing maintenance may be required to ensure proper operation. When using recycled plastic in soil, considering the possibility of chemical leaching from the plastic into the soil is essential (Nakashima et al., 2012; Kristanti et al., 2022; Sobhani et al., 2021; Bläsing and Amelung, 2018). Some plastics, especially those not intended for use in soil, may contain chemicals that are toxic to plants and animals. Over time, these chemicals can leach into the soil, potentially contaminating it and affecting plant and animal health. When selecting recycled plastic for use in soil, care must be taken to minimise the risk of chemical leaching. Given that this type of plastic is less likely to contain harmful chemicals, it is generally recommended to use recycled plastic that is designed for use in soil. Additionally, the potential for recycled plastic to break down into microplastics over time must be considered (de Souza Machado et al., 2018, 2019; Okoffo et al., 2021). Concerns with the usage of recycled plastics as a filler or addition for construction include the abundance of microplastics. The building materials known as ‘RESIN8’ were created and copyrighted by Loria-Salazar and Gomez-Sandoval (2021). The materials are composed of an extruded blend of 80% recycled plastic (from various sources) and 20% mineral ingredients (mainly lime and wood ash). Concrete masonry blocks and pavers have been successfully made using this cutting-edge material. The authors claimed that after an extremely abrasive wheel loading operation, the microplastic release potential of RESIN8 pavers appeared insignificant. To minimise the risk of microplastic pollution, the disposal of recy­ cled plastic should also be considered. For instance, plastic is less likely to break down into smaller pieces that might form microplastics if it is disposed of in a landfill that is intended to confine waste and prevent it from entering the environment. The pyrolysis of plastic waste and monomer recovery (e.g., PMMA) are other methods for permanent disposal. Furthermore, plastic waste can serve as an energy source for electricity. After being incinerated, by-products, including bottom ash (BA) and fly ash (FA), are produced. These ashes have been successfully utilised by adding building materials to improve the quality of the resulting products. Incineration is not the end of plastic waste, as Yang et al. (2021a) demonstrated; BA might be a source of microplastics released into the environment. There are nine kinds of plastic, with PP and PS being the most common. BA was a possible source of micro­ plastics released into the environment, as demonstrated by their find­ ings. Therefore, the authors believed that microplastics could be able to terminate by incineration process. It is common knowledge that FA and BA were substituted for the binder component as supplementary cementing materials in concrete to promote quality and sustainability by utilizing industrial by-products. The pozzolanic reactions of hydraulic cement generally take place when incorporated with FA and BA, leading to a densified porous matrix. The process of densifying a porous matrix leads to a concrete structure that exhibits enhanced strength and dura­ bility. This methodology has been employed for several decades. It has recently come into focus that the utilisation of FA and BA may exacer­ bate the issue of microplastics, which is already a matter of substantial apprehension. Additional investigation is warranted regarding the management of BA prior to pyrolysis, during the process of fine grinding or prior to its incorporation into building materials. It is notable to highlight that many industrial by-products and agri­ cultural ashes, including but not limited to silica fume, blast furnace slag, rice husk ash, corn ash and paper sludge ash, have been extensively employed in the cement and concrete industries to enhance the perfor­ mance of final products, reduce material cost and mitigate carbon footprint emissions. The diverse range of aforementioned materials ne­ cessitates an evaluation of their respective effects on the release of microplastics. For the built environment during the waste management process, as aforementioned, microplastic can be generated from the fragments of plastic where degradation takes place. A waste landfill seems to be one of the key sources of microplastics. It is reported that wind abrasion in outdoor environments could fragment microplastics from textiles and revitalize them from landfills (Hu et al., 2022). Atmospheric emissions from wind abrasion at landfill sites were estimated to be 0.16 pieces/t of waste/h, and the polymer type, shape and component were related to the waste composition at the time (Hu et al., 2022). Rezaei et al. (Rillig, 2012) also ran a wind simulation predicting microplastics erosion and suspension on their surface as airborne pollution at a rate ranging from 0.08 to 1.48 mg/m2/min. Moreover, recent research from Costa-Gómez et al. (2023) investigated the PM10 and PM2.5 from the decomposition process of EPS component and found that EPS generates both PM10 and PM2.5 at concentrations of 2.1 mg/m3 and 1.8 mg/m3, respectively. For thermal degradation, Revell et al. (2021) investigated the radiative forcing by airborne microplastics, assuming a consistent surface con­ centration of 1 microplastic particle/m3 and a vertical distribution up to 10 km altitude, with the emphasis on the light absorption of micro­ plastics. Their calculation showed around 0.044 ± 0.399 fW m− 2 in the current built environment. This airborne pollution from both diverse weathering (e.g. wind erosion) and thermal decomposition can be found in any outdoor environment. Hence, plastic waste management in construction activities and a sustainable built environment can be accomplished via better resource allocation, material recovery and an enhanced waste management sys­ tem, especially for developing countries with a limited budget. How­ ever, the primary goal is to create robust legislative procedures for the management of building waste, as there is currently a draft legislation aiming to protect human health from many international organisations like the World Health Organization (WHO) and the European Commis­ sion (EC) (Gao and Sun, 2021). These procedures can lessen the problem of dumping in open lands, which is made worse by the combination of municipal solid waste and unauthorised recycling that takes place in these unregulated areas (Kittinaraporn et al., 2022). In sum, the proper methods for preventing recycled plastic waste from transforming into microplastics are pyrolysis and monomer recovery. 11 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 7. Microplastics as a source of the release of other contaminants 8. Discussion and suggested future works Microplastics are considered sources of dissolved organic carbon and toxic contaminants including, hydrophobic organic pollutants, heavy metals, polybrominated diphenyl ethers, bisphenol A, polychlorinated biphenyls, polybrominated diphenyl ethers and volatile organic com­ pounds. In addition, microplastics serve as carriers for hazardous con­ taminants (Zhou et al., 2022). The buildup of microplastics promotes their bioaccumulation and toxicity. On the contrary, microplastics are hypothesised to function as a sink for pollutants, reducing the likelihood of their bioaccumulation (Xu et al., 2020c). Their bioaccumulation can directly influence the carbon cycle through microbial processes, plant growth, or litter decomposition (Omay et al., 1997). Contaminants adsorbed to the surface of microplastics also aid in identifying probable sources. Due to their vast surface area, microplastics may absorb several hazardous substances (Luo et al., 2019; Monira et al., 2021). This adsorption of pollutants on microplastics is highly dependent on phys­ icochemical parameters such as polymer chemistry, polymer structure, specific surface area, polarity, crystallinity and pore size distribution. Furthermore, the sizes and characteristics of microplastics affect the efficacy of detection and treatment methods for both microplastics and other contaminants (Khan et al., 2022). For instance, Abbasi et al. (2017) examined microplastics and heavy metals in street dust in Iran and found road traffic emission pollutants such as Cu, Zn, Sb, Hg, Pb and Mo, as well as resuspended soil particles, including Al, Mn, Ni, Ti, Cd and Co. It is reported that automobile traffic, road surface deterioration, the tear and wear of brake pads, the leaking of brake fluids, the deterioration of road paint and air deposition were the primary causes of pollution in this region. With these excessive levels of heavy metals, the calculated potential ecological risk index indicated that the risk was between moderate and high. These heavy metals ulti­ mately persist as airborne contaminants and cause health risks, such as by exerting negative effects on the neurological, cardiovascular and reproductive systems. Other impacts include decreased IQ, poor atten­ tion and abnormal behavior (Prata et al., 2022c). WHO reported the air quality database in 2022, entailing guidelines for dealing with PM10, PM2.5 and NO2 in urban environments, and emphasized in the major cities that 99% of global population breathes air that exceeds the limits (Nascimento et al., 2022). This is not accounted for in the microplastics issue yet. Overall, not only the entry of microplastics into the human body is the problem but also the introduction of other contaminants that accompany microplastics, thereby yielding multifarious impacts on human health. This section reviews the previous literature on microplastic emis­ sions in the construction and built environment industries. There is a lack of current reviews in this field. The relevant research is very recent, particularly in China and developed nations. China has been identified as the leading producer of plastic waste, particularly given the lack of an effective management strategy to date. Due to the fact that more than 90% of the research has been publicly disclosed during the past five years (Fig. 3), there is no amalgamated dataset that considers the big picture. The lack of scientific consensus on quantitative reporting ap­ proaches increases the difficulty of regulating microplastic exposure in the environment. Another major concern is the amount of microplastics transported from construction sites to land, as well as the amount of microplastics consumed by humans, such that an effective monitoring process to collect the data is imperative (Yang et al., 2021b). Before a suitable solution and standard methods may be established with regard to the management of microplastic emissions, there is a need for addi­ tional time to be devoted to doing research in this area (Ta and T.’ Babel, 2022). The possibilities to overcome the microplastics release should be performed for further investigation, as outlined in Fig. 8. 8.1. Encapsulation and composite method In today’s construction activities and built environment, a large portion of construction projects are conducted at the same site. This seems to be especially done in urban areas with intensified populations where there is no free space available anymore (McKim et al., 2000; Burton, 2002; Rees, 2021). This means that intensive construction ac­ tivities in big cities in any part of the world deal with demolition. However, no current research reveals issues with the effect of demolition on microplastics. Also, Fu et al. (2023) asserted that the knowledge regarding microplastics was flawed and limited, especially in the social science study. The research in this field, such as civil engineering, environmental engineering, architecture, construction management, law, social science and urban development study greatly influences our liveable places and offers the requisite experiments to investigate. As discussed previously, demolition is a way of detaching microplastics from concrete (instead of encapsulating them) via leaching and airborne dust. Demolition activities generate substantial amounts of small matter, such as PM2.5 (Dorevitch et al., 2006; Cheng et al., 2021) and micro­ plastic particles (Faruqi and Siddiqui, 2020; Kawecki and Nowack, 2020b). This problem seemingly intensifies in urban areas where high-rise buildings captivate air containing small matter to stay in place Fig. 8. Outline of possible solution for minimizing the microplastic release issue. 12 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 as deposition microplastics (Piazzolla et al., 2020; Xu et al., 2022; O’Brien et al., 2023). Undoubtably, as new construction and building projects, as well as the remaining old construction and building projects, introduce plastics into building materials and structural components, exposure to microplastics will be of great concern. As noted in Section 5, BA and FA have been widely incorporated into concrete mixtures for many decades. These ashes are recognized as a potential source of microplastics and were found in many regions (Zhang et al., 2015; Ma et al., 2022; Bungau et al., 2022; Diefenderfer and Apeagyei, 2011). Several countries have executed construction projects with concrete containing BA and FA passing their life expectancy (for example, a 50-year service life) (Lizárraga-Mendiola et al., 2022; Monkul and Özhan, 2021; Sereewatthanawut et al., 2023). Hence, many construc­ tions nowadays cannot be in service any longer; as a result, demolition is becoming an important aspect of modern construction, and these encapsulated ashes (but can also from rice husk ash, corn ash, silica fume, blast-furnace slag) have been discharged (Prasittisopin and Trejo, 2013b; Channa et al., 2022; He et al., 2021; Prasittisopin et al., 2019; Yogarathinam et al., 2022). Concerning synthetic fibres and plastics, the issue can be postponed for a few decades, as their use in concrete structures for high-quality products such as ultra-high-performance concrete, additive-manufacturing (3D-printing) concrete and self-consolidating concrete is still in good condition (Prasittisopin et al., 2021; Tuvayanond and Prasittisopin, 2023; Prasittisopin et al.). Encapsulation with high quality concrete or building material pre­ sents a viable option for mitigating microplastic emissions in construc­ tion and built environments. The use of high-strength and ultra-highstrength concretes is believed to have been used in certain major con­ crete projects today since the material degrade under harsh weather conditions considerably less quickly than normal strength and lowstrength concrete do. It is possible to reduce and address the problem of microplastic leaching from such high-strength and ultra-high-strength concretes. An additional proposition involves the utilisation of surface hard­ ening agents, such as lithium- and silica-based compounds, which are commonly employed in pavement and floor contexts to mitigate abra­ sion. With the implementation of regular maintenance, the issue of microplastic leaching has the potential to be ultimately resolved. Nevertheless, a thorough investigation is required to evaluate and authenticate these two technical demonstrations. It is important to highlight that when building elements are pre­ fabricated, solutions for sandwiched systems, such as precast concrete, composite walls, and prefabricated room units, can be predesigned. Composite systems can be created by omitting plastic from the exterior and adding a plastic component to the interior wall. For instance, the plastering system should not include any plastic in the mix design; however, the middle portion of the composites can benefit from the addition of plastic. Another illustration involves employing a metal external wall, like aluminum cladding and a plastic-rich component in the middle part of the sandwiched systems. environment and are valuable. This is one means to accelerate the decomposition of synthetic plastic wastes in construction. Alternatively, research on self-healing concrete where the biotech­ nology of microbials is presently available (Van Wylick et al., 2021; Feng et al., 2021; Elkhateeb et al., 2022). The self-healing concrete, which has been employed in some experiments, can be used to lessen the leaching of microplastics. This is due to the material’s ability to mend itself by activating CaCO3 precipitation, which caused the crack that could have been the first initiated pit to disappear. It is important to confirm this field of bioorganism-based self-healing concrete. There should be extensive research and development done in this area. The vital investigation of an alternative approach to utilizing biodegradable plastics, such as polylactic acid (PLA) and biodegradable co-polyester, in the context of construction and building materials is seemingly warranted. The replacement of biodegradable plastics with synthetic polymers may prove to be an attractive choice for temporary construction projects. The aforementioned applications, including tem­ porary shelters, concrete curing sheets, covering sheets, and mulching nets, are considered to be the most straightforward alternatives for substitution. 8.3. Use of alternative natural materials Reducing the use of plastic-based materials in construction and built environment is seemingly a crucial step in reducing the release of microplastics into the environment. Natural materials, such as wood, bamboo, mass timber and hemp, offer a sustainable and environmen­ tally friendly alternative to plastic-based insulation and other con­ struction materials. Either adoption of artisanal lime and graphene technology or water-based coating may offer alternative methods to plastic-based paint. Using these materials not only reduces the release of microplastics but also has additional benefits, such as reducing the carbon footprint of buildings and promoting sustainable building prac­ tices. This is because using these materials is not considered deforesta­ tion any longer since the forest can be regenerated in an efficient manner. However, while these strategies offer a promising approach to reducing the release of microplastics in construction and built envi­ ronment, they are not without their challenges. For example, using alternative materials may be more expensive than using normal plasticbased materials and may require additional expertise or training for construction workers. Additionally, waste management practices may require significant changes to existing construction practices, which can be difficult to implement in practice (Ali et al., 2021; Arnaud et al., 2020; Le Corre et al., 2021). The utilisation of non-plastic building materials is considered an ideal approach, albeit its practicality may not be as high as that of concrete due to performance, cost and availability constraints. It is recommended that feasibility studies based on social, environmental and economic impacts be conducted to explore the potential of alter­ native natural materials as a substitute for the current building material. At present, it is feasible to establish a green branding and sustainable marketing strategy to promote the Sustainable Development Goals (SDG) and particular green building initiatives. It can be anticipated that if the restriction on the utilisation of non-plastic-based construction materials is lifted, there will be significant potential for natural building materials in the future. 8.2. Biochemical technology Biochemical technology has progressed to the extent that it can potentially assist the degradation rates of plastics, which in turn can lower the lasting life of microplastics. As an illustration, Chen et al. (2022) described a method for decomposing microplastics that included the following processes: 1) catalytic decomposition of microplastics into organic compounds that are safe for the environment (carbon dioxide and water); 2) catalytic recycling and upcycling of plastic wastes into monomers, fuels and chemicals that have been valorised (Mainardis et al., 2021; Comninellis et al., 2008). Several catalytic processes, such as photocatalysis (Ebrahimbabaie et al., 2022), enhanced oxidation processes and biotechnology (Hou et al., 2021), are promising and ecologically favourable possibilities for the transformation of micro­ plastics and plastic wastes into products that are safe for the 8.4. DPSIR model strategy Concerning the emissions of microplastics in the construction in­ dustries and built environment, the implementation of the existing policy of the DPSIR (i.e., driving force, pressure, state, impact and response) paradigm that was established by the European Environ­ mental Agency is considered (Rouillard et al., 2018). This paradigm aims to bio-diversify the interactions between society and the environ­ ment, namely, the current knowledge on the origins of microplastics in 13 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 the environment, the abundance, mobility and destination of micro­ plastics distributed throughout the many environmental compartments; and the socio-economic and ecological implications of these interactions (Samandra et al., 2022; Zhao et al., 2022). Fig. 9 depicts the DPSIR model analysis for microplastic exposure in the building and construc­ tion industries. It is believed that a comprehensive evaluation of each component of the DPSIR model strategy is necessary to provide valuable evidence of its implementation. diminishing microplastic emission should widely take place (Tursi et al., 2022). The investigation and establishment of social and environmental policies pertaining to microplastic emissions can serve as a significant research area for social science, humanity, urban planning and legisla­ tive perspectives on a global, regional and local level. In the context of Thailand, for instance, a number of prominent environmental scientists have emerged, who have attempted to provide insights into the issue of microplastic release in the construction and built environment. This represents the initial phase of establishing a formal strategy to address and alleviate the issue. 8.5. Social awareness and policy 9. Conclusion There is a need for greater awareness and education about the risks associated with microplastics in the construction and built environment which can be conducted based on the SDG policy. This includes educating construction workers, building owners, and other stake­ holders about the potential environmental and health impacts of microplastics, establishing proper guidelines locally as well as strategies to reduce their release. Greater awareness and education can help pro­ mote the adoption of sustainable building practices and encourage greater investment in research and development of alternative materials (Negrelli and Silva, 2021). A framework to precisely evaluate the impact of microplastics on human health should include human exposure characterization, microplastics’ characterization, method of intake and exposure duration (World Health Organization, 2022). Additionally, the WHO (World Health Organization, 2022) also reported the applicability of a risk assessment framework that entailed statistical analysis, end­ points, dose-response relationships, concentration ranges, effect thresholds and test particle relevance. The framework programme relating microplastics exposure to human health is underway. As aforementioned, many international organisations such as WHO and EC have established legislative drafts and cooperative acts to deal with these microplastics issues. The United Nation (UN) (United Na­ tions, 2022) created Resolution 5/14 in May 2022 (“End plastic pollu­ tion: Towards an international legally binding instrument”) to prepare for the work of the intergovernmental negotiations. The EC (European Commission, 2023) developed an EU Green Deal in February 2023 with the goal of reducing microplastics release by around 30% by 2030. When such international policies can be achieved, regional and local organisations of each nation should be adopted, and the acts for A systematic review and analysis of state-of-the-art published articles on the topic of the use of microplastics in construction and built envi­ ronment was carried out. The following are some of the inferences that may be drawn: • PP, PE and PVC account for 60% of the world’s thermoplastic output mainly used in the building and construction sectors as aggregates, macrofibres, microfibres and building parts. • Many sources of microplastics used in construction and built envi­ ronment, including fabrics, fibre reinforcement in concrete, paints, plastic beads and tyres and roads, have been investigated. Among them, tyre and road applications were reported to generate micro­ plastics the most. In contrast, while microplastics present in building and construction paints may not have been a significant concern, their quantity is relatively substantial. • Microplastics enter the human body through leaching (microplastics from land enter the marine system, and then humans consume sea animals that eat microplastics) and inhaling airborne particle pollution at construction and building sites. • The current recycled waste management is the development of effective regulatory processes for managing the wastes, as recycled plastics and burnt ashes would finally yield microplastics. • FA and BA typically substituted cement in concrete could yield microplastics, other agricultural ashes and industrial ashes might also release microplastics. Fig. 9. DPSIR model analysis for microplastic exposure in the construction and built environment. 14 L. Prasittisopin et al. Developments in the Built Environment 15 (2023) 100188 • The utilisation of encapsulation and composite Method, wherein the cement matrix was designed to possess high strength and the plastic component was layered in the inner part, could serve as an important strategy in mitigating the release of microplastics. • The DPSIR model may depict the holistic process of microplastic release in building and construction, similar to other activities. Each component of this DPSIR model should be further assessed. • The exploration of bio-chemical technology, like catalytic processes and photocatalysis, self-healing concrete and bio-degradable poly­ mers should be pursued as a potential alternative to conventional products. • Using natural, non-plastic construction materials reduced plastic use. Regulating the material was important despite its lower practicality than concrete due to performance, cost, and availability issues. Feasibility studies should assess the social, environmental, and eco­ nomic impacts of a project. • Social science, humanity, urban planning, and legislation in con­ struction and built environment fields could study microplastic emission policies at the global, regional, and local levels.

The exploration and advancement of microplastics for utilisation in the construction and built environment hold great importance; however, the existing research on this topic has only recently become accessible. A significant disparity persists between empirical inquiry and efforts to lessen the issue, evaluate its effects, implement effective management strategies, and formulate protocols necessitating additional study.
