Prosjektoversikt 2004 PROFO 1 Undersjøisk deponering av forurensede muddermasser i marine, anoksiske bassenger effekter av tildekking Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Schaanning, Morten T. Forsker Prosjektnr: 134419/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2000-31.12.2004 2000: 250,000 2001: 350,000 2002: 430,000 2003: 430,000 2004: 250,000 Hovedmålet med prosjektet er å framskaffe kunnskap om underjordisk deponering av forurensede masser (f.eks. havnesedimenter) i avgrensede, anoksiske bassenger er en miljømessig akseptabel løsning under forutsetning av at massene etter endt deponering tildekkes med egnede rene masser. Delmålene er å fastslå: - hvilke egenskaper dekkmassene bør ha for å få til en effektiv isolering av de forurensede sedimentene (kornstørrelse, mineralsammensetning og innhold av organisk materiale) - hvilken tykkelse dekklaget bør ha for å stoppe diffusiv og advektiv transport av miljøgifter gjennom dekkmassende og for å hindre at gravende dyr blir eksponert for forurensede sedimenter - hva som skjer (fysisk, kjemisk og biologisk) hvis det anoksiske bassenget på et tidspunkt etter en dypvannsfornyelse blir oksisk Contaminated sediments accumulated near point sources and in harbours appear in shallow water. These areas are exposed to currents, waves, underwater constructions and turbulence from ship propellers. Due to this high energy environment contaminated sediments are frequently resuspended and replaced. This increases the potential of remobilisation and bioaccumulation in marine organisms. As a consequence the contaminated sediments should be removed (dredged) to obtain an environmental improvement. At the same time the sailing depths in harbours are increased (maintenance dredging). The problem is an environmental safe disposal of contaminated dredged material. One alternative is the disposal of the dredged material in natural anoxic basins followed by capping with clean sediments. The removal of contaminated sediments from shallow and productive areas and deep water placement in abiotic, anoxic environment may have the following advantages: - The remobilisation of contaminants from the dredged material may be inhibited by capping. - By adding a cap sufficiently thick to exceed the depth of bioturbation the organisms established on top of the cap will not be exposed to contaminated sediments. 2 Ellasjøen, Bear Island - a mass balance study of a highly contaminated arctic area Prosjektansvarlig: Akvaplan Niva AS Prosjektleder: Christensen, Guttorm Normann Forsker Prosjektnr: 135632/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2000-31.12.2004 2000: 300,000 2001: 1,200,000 2002: 800,000 2003: 500,000 2004: 300,000 Hovedmålsetting med prosjektet er å bestemme kilder og transportveier ved episodiske tilfeller, samt bestemme belastning av langtransporterte organiske miljøgifter tilført med luft og deponert i et avgrenset arktisk område (Bjørnøya) i Barentshavet. Dette skal gjennomføres ved kvalitativ og kvantitativ bestemmelse av den atmosfæriske transporten og deposisjon fra nedbør, fordampingsprosesser, 3D-trajektorieanalyser i tillegg til studier av miljøgiftenes oppførsel i de terrestriske og limniske systemene. Tidligere innsamlet datamateriale og data fra denne studien vil gi et omfattende grunnlag for utarbeidelse av teoretiske modeller som beskriver transport, deposisjon og akkumulering av langtransporterte organiske miljøgifter i et arktisk område. Målsetting for 2000 og 2001 vil være å gjennomføre målinger og analyser av miljøgifter i regn, snø og tåke. Videre vil det bli gjennomført en sammenligning av meteorologiske forhold mellom Ellasjøen og et område nord på Bjørnøya. Ved forhøyede konsentrasjoner av miljøgifter i måleperioden (episoder) vil det bli gjennomført 3D-trajektorieanalyser for å vurdere kilder. As there is no local source to explain the elevated levels of contaminants on Bear Island, the questions that need to be addressed include the source of these contaminants, the transport pathways that deliver these contaminants to this site, total deposition and finally contaminant fate including biological uptake and effects. As outlined in the AMAP report, atmospheric long-range transport is a very important source for a selected number of semi-volatile compounds, including the above mentioned chemicals. The project will carry out a mass balance study on the sources and the sinks of POPs for the Ellasjøen area. The results obtained from the field studies will be used for an integrative modelling of the POP fate in this well-defined area. Furthermore, the model developed during the project can be used for other related studies to estimate POP input and behavior. The basis for the project is a suspicion that Bear Island is situated in a "contaminant focusing zone". Whether or not this suspicion is correct, will be a major research issue in the project. Two overall questions forms the basis for the project: - How can local meteorological conditions influence the principles of global atmospheric transport of POPs? - How does a pristine and fragile ecosystem deal with a high POP input? The project will provide unique data for the estimation of atmospheric input into the Norwegian Arctic. In connection with the already installed sampling facilities in Ny-ζlesund, the data from the Ellasjøen sample station can be used to model and predict atmospheric transport of a variety of airborne persistant pollutants. In addition, the Ellasjøen project can be seen as a pilot study to estimate the influence of small scale or local meteorological parameters in a large-scale atmospheric transport process. The results can be used to describe the transport and deposition of persistant pollutants and their fate in a pristine ecosystem. The obtained data can further be used to support political decision-makers on a national and international level. 3 Mykorrhiza-soppfloraen i heipreget skog med høy nitrogen-belastning, effekter på produksjon og biodiversitet Prosjektansvarlig: NINA - Oslo Prosjektleder: Brandrud, Tor Erik Forsker Prosjektnr: 140391/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2001-31.12.2005 2001: 120,000 2002: 95,000 2003: 95,000 2004: 95,000 2005: 175,000 Å vise hvordan endringer av mykorrhizasoppfloraen i heipregete furuskogområder henger sammen med variasjon i nitrogenbelastning, herunder: - analysere endringer og tap av mangfold i definerte furuskogsutforminger i belastede områder som avvik fra 1) lite belastet referanseområde og 2) forventet naturtilstand, blant annet ved bruk av multivariat statistikk - vurdere tålegrenser for følsomme arter/artsgrupper i f.t. nitrogendeposisjon og nitrogenmetning - etablere/videreføre tidsstudier av referanseområder med ulik nitrogenbelastning. In large-scale-Nitrogen-experiments (the NITREX programme) the mycorrhizal fungi stands out as one of the most sensitive biotoa with respect to N-saturation in coniferous forests. Similar, negative effects on the mycorrhizal fungi are to be expected in southernmost Norway, in shallow-soil, open pine forests where Nleachage has been recorded. These effects are expected to increase in the future because of: 1. Continuous high N-deposition (almost unchanged levels). 2. Gradually increased degree of N-saturation in the soil. 3. Climate changes leading to increased decomposition and release of accumulated, organic N. The mycorrhizal fungus flora will be investigated in ecologically similar, oligotrophic, open, shallow-soil pine forests along a gradient in N-deposition, including permanent plots investigated first time 10 years ago. Possible changes and loss of biodiversity in plots with high N-deposition will be measured as deviation from (i) reference site conditions (site with low deposition), and (ii) deviation from expected natural conditions. Multivariate methods will be applied. Critical loads will be estimated for sensitive species/species groups, that is taxa that according to experimental studies seem to be important bioindicators on N-pollution. 4 Utlekking, transport, omdanning og akkumulering av miljøgifter fra deponi til marint miljø Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Bakke, Torgeir Heggelund Forskningsleder Prosjektnr: 140405/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2001-31.12.2004 2001: 300,000 2002: 800,000 2003: 800,000 2004: 300,000 Hovedmål: å øke kunnskapen om hvordan sjønære avfallsdeponier fungerer som miljøgiftkilder til fjorder, og hvordan transportveier, spredning, omsetning og bioakkumulering av tungmetaller er avhengig av kildeegenskaper, tilstandsform, salinitetsgradienter og partikkelforhold. Delmål: -Klarlegge hvordan tungmetallers mobilitet og tilstandsform i sjønære deponier endres som følge av faktorer som gir utlekking. - Bedre kunnskapen om hvordan salinitet og partikkelforhold i en fjord styrer transport, omsetning, sedimentering og bioakkumulering av tungmetaller med ulik tilstandsform. - Sammenlikne bioindikatorers og passive indikatorers evne til å påvise episodisk tungmetalltilførsel som funksjon av tilstandsform, salinitet og partikkelforhold. Shoreline waste deposits are in focus as contaminant sources in Norwegian fjords. Heavy metals appear in various physical and chemical state in such waste, and processes which cause leachage may change the state. Metals leaching to the sea are absorbed to and desorbed from particles. These processes are regulated by state of the metals, particle properties, and conditions in the receiving water, e.g. salinity. Dispersion, sedimentation and bioaccumulation in the fjord may thus be a function of conditions in the waste deposit and in the recipient, as well as of the episodic factors that cause the leaching. The project aims to study a set of hypotheses regarding the significance of these factors in affecting the fate of metals in an estuarine fjord system. This will be done through a series of mesocosm experiments where a model waste deposit is coupled to a model fjord with several basins separated by sills. The mesocosm system is established at the NIVA Marine Research Station Solbergstrand. The project will study the significance of episodic factors causing leaching of heavy metals from the model waste deposit, and compare how the metals are distributed in water, suspended matter, bottom sediment, accumulating organisms (bioindicators) and passive samplers across a salinity gradient along the model fjord. The experiments will comprise analyses of total metal concentrations, binding state, metal origin (through stable isotope ratios), particle characteristics, and a range of supporting parameters in the various compartments of the waste deposit and the fjord. 5 Metodikk for overvåkning og risikovurdering av effekter av ulike persistente miljøgifter i marine økosystem Prosjektansvarlig: Biologi, Institutt for,Norges teknisknaturvitenskapelige universitet Prosjektleder: Jenssen, Bjørn Munro Professor Prosjektnr: 141369/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 15.8.2001-31.12.2004 2001: 251,875 2002: 557,000 2003: 570,000 2004: 320,125 Basert på undersøkelser av biomarkører i egg eller nyklekte unger av utvalgte sjøfuglarter, vil en utvikle og etablere en overvåkingsmetodikk som gjør det muig å foreta en kostnadseffektiv risikovurdering med hensyn til effekter av ulike persistente organiske miljøgifter i marine økosystemer. I første fase undersøkes effekter av kontrollert eksponering for polybromerte difenyl etere, toksafener og PCB i egg, samt kombinasjoner av disse, på biomarkører. Dette for å undersøke evt. synergistiske og antagonistiske effekter. I fase to undersøkes biomarkører i egg/unger fra ulike lokaliteter på Svalbard og/eller Norge. I fase tre gjøes en risikovurdering basert på resultater fra labstudier og felt. 6 Spredning av effekter av persistente organiske miljøgifter i en toppredator i det marine økosystemet i Barentshavregionen Prosjektansvarlig: NINA,Arktisk økologi Prosjektleder: Bustnes, Jan Ove Seniorforsker Prosjektnr: 141443/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2001-31.12.2004 2001: 600,000 2002: 600,000 2003: 400,000 2004: 400,000 Hovedmål: Å undersøke den geografiske fordelingen og demografiske effekter av persistente organiske miljøgifter hos svartbak i en gradient langs kysten av Nord-Norge Delmål: 1. Å måle nivåer og fordeling av organiske miljøgifter hos svartbak som hekker i forskjellige kolonier langs kysten av Nord-Norge. 2. Å undersøke transportveier for persistente organiske miljøgifter på bakgrunn av stoffsammensetning (PCB-kongenere og pesticider) hos svartbak som hekker i forskjellige kolonier langs norskekysten. 3. Å undersøke om dagens nivåer og fordeling av organiske miljøgifter hos svartbak påvirker demografiske parametre. 4. Gjennomføre sensitivitets- og elastisitetsanalyser for å vurdere effekter av miljøgifter på populasjonsdynamikken hos måkefugl i Barentshavregionen. A gap in the knowledge about long-transported pollution in the northern areas is the distribution of persistent organochlorines in top predators over a large geographical scale. A general assumption is that the Arctic is heavily polluted by such compounds, but studies from adjacent temperate areas to back up this claim, are lacking. By studying great black-backed gull Larus marinus this project will examine levels and composition of organochlorines in a gradient along the coast of northern Norway. Moreover, the project will study the effects of the present level of organochlorines on important demographic parameters. This will provide information about the pollution in the Arctic compared to nearby temperate areas. It will also give information about sources and transport of organochlorines, and the effects of these compounds on the population dynamics of a top, predator in the area. 7 Nitrogenets rolle i forsuring i fremtiden; Modellerte, empiriske og eksperimentelle studier av endret nitrogenavrenning Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Monsen, Brit Lisa Skjelkvåle Forskningsleder Prosjektnr: 141498/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 13.8.2001-13.5.2006 2001: 174,000 2002: 25,000 2003: 308,334 2004: 381,000 2005: 381,000 2006: 133,500 Hovedmål: Øke forståelsen av hvilke prosesser som er styrende for nitrogenlekkasje fra fjell og heiområder med høy atmosfærisk N-belastning. Delmål: - Avklare dagens status med hensyn på nitrogenlekkasje og utvikling av nitrogenavrenning de siste 20 år fra fjell- og heiområder. Teste eventuelle empiriske sammenhenger mellom ulike feltegenskaper og nitrat i avrenningen. - Kvantifisere immobilisering (retensjon) av N i ulike felttyper. Utarbeide grunnlag for prognoser om fremtidig Nlekkasje i ulike typer økosystem med hovedvekt på fjellog heiområder. 8 Consequences of contaminant releases into the arctic marine environment from Sibirian Rivers (Comer) Prosjektansvarlig: Statens strålevern Prosjektleder: Iosjpe, Mikhail Seniorforsker Prosjektnr: 147437/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2002-31.12.2004 2002: 330,000 2003: 540,000 2004: 400,000 The prime aim of this project will be to assess the vulnerability of Arctic coastal areas to contaminant input from large rivers and their estuaries, namely the Ob and Yenisey river systems. This aim will be achieved by (1) improving the methodology for modeling releases from large, point-sources of contaminants, (2) collecting field data to validate contaminant transport models, and (3) tying the model results to formal analyses of sensitivity of coastal resources. The project is expected to result in improved assessment tools that wiIl aid in the further development of better protection strategies for Arctic resources. 1. Site-specific information will be gathered from the estuaries in summer 2001. The field programme is funded separately through an EU project. As part of the project, one will gather data on particle distributions and their associated contaminant loads and sediment deposition and mixing rates. The information will be used in model simulations of discharges from the estuaries. 2. The sensitivity analysis will be based on results of model simulations of contaminant distributions. These simulations will be conducted using an improved box model. The following improvements will be made to the box model: (i) introduction of a heavy metals module, (ii) improvement of the information data base used in the model, and (iii) introduction of an ice module. 3. Connecting the results of the modeling work to the sensitivity analysis, the project will determine the likely consequences to the marine environment/habitats, biota and populations from contamination discharges from the Ob and Yenisey estuaries. The project will identify "conflict areas" where high levels of contaminant deposition in the environment coincide with particularly sensitive habitats or populations of Arctic species. The final results will be presented visually as sensitivity maps presenting the distribution of sensitive species and habitats in the region. 9 Stressproteiner og genekspresjon. Intracellulare mekanismer, med hovedvekt på studier av dyr fra tungmetallforurensede områder Prosjektansvarlig: Biologi, Institutt for,Norges teknisknaturvitenskapelige universitet Prosjektleder: Andersen, Rolf Arvid Professor Prosjektnr: 147474/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.4.2003-31.3.2006 2003: 419,250 2004: 655,000 2005: 555,000 2006: 138,750 1. Undersøke hvordan dyr fra tungmetallbelastede miljøer er påvirket av forurensninger på vevs- og cellenivå. 2. Kombinere studier av stressproteiner som metallothionein, enzymer koblet til håndtering av oksygenradikaler (catalase, superoxide dismutase og gluthation peroxidase) og heat shock proteins med genom-studier av disse stressproteinenes gener for å etablere sammenhenger mellom stressnivå og gen- ekspresjon i ulike vevstyper som f.eks. gjelle og lever i fisk. 3. Utnytte mulighetene som åpner seg med det nye fagfeltet toxicogenomics innenfor tradisjonelle økotoksikologiske problemstillinger, ved å bruke DNA macro/microarray teknikker for å studere hvordan en lang rekke av gener uttrykkes i forskjellige celletyper etter eksponering for miljøgifter. 10 Strømningsveier i nedbørfelt vann- partikler-pesticider Prosjektansvarlig: Jordforsk Prosjektleder: Øygarden, Lillian Forsker Prosjektnr: 147954/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2002-31.12.2004 2002: 512,308 2003: 1,147,692 2004: 820,000 Hovedmål: Øke kunnskap om strømningsveier for næringsstoffer, partikler og pesticider i vann i små nedbørfelt dominert av jordbruk. Delmål: 1. Styrke koblingen mellom forskning og overvåking for å øke kunnskapsgrunnlaget for de prosesser som leder til avrenning av næringsstoffer og pesticider fra jordbruksarealer. 2. Videreutvikle metodikk og øke kompetansen på bruk av tracere som hjelpemiddel for å identifisere kilder, strømningsmønster, oppholdstider og transportveier i nedbørfelt. 3. Bedre risikovurderinger og grunnlaget for valg av effektive og optimale tiltak for å redusere avrenning av næringsstoffer og pesticider. Identifisere og dokumentere forskjeller mellom og innen små nedbørfelt som gir ulik tap til vannforekomster. 11 Statistical techniques for risk assessment of environmental effects of pollutants from diffuse sources Prosjektansvarlig: Norsk Regnesentral Prosjektleder: Aldrin, Magne Tommy Forsker Prosjektnr: 148307/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2002-31.12.2004 2002: 200,000 2003: 400,000 2004: 300,000 Principal objective: To establish a common mathematical framework for risk analysis of diffuse pollutants distributed in space and space-time. Sub-goals: 1. Develop techniques for quantifying various sources of uncertainty (measurements, model structure, target populations) in risk estimates. 2. Develop techniques for scaling-up risk assessment and uncertainty estimates from single sites to region. 3. Developing techniques for visualizing results (spatial, spatio-temporal) of risk and uncertainty such that these are suitable for use by policy-makers. The project will develop a common statistical framework for risk analysis of diffuse pollutants with space-time characteristics. For such problems, the aim is to improve the basis for environmental decision making by providing a link from pollutant exposure to the probability of adverse effects. This may contribute to a new approach for setting environmental standards for diffuse pollutants. The methods will be general, enabling use within a broad range of applications. Surface water acidification and persistent organic compounds in fish will be used as case studies, making the research directly relevant to the work done under the UN-BCE Conventi for Long Range Transport of Air Pollutants. The case studies will also link the research to data from ongoing national monitoring programs. 12 Atmosphere speciation of mercury Prosjektansvarlig: Norsk institutt for luftforskning Prosjektleder: Berg, Torunn Seniorforsker Prosjektnr: 148404/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.7.2002-30.7.2005 2002: 278,000 2003: 535,000 2004: 555,000 2005: 277,500 The overall aim of the project is: To quantify the atmospheric cycling of different species of mercury. The following spesific questions will be addressed: 1. What are the reaction mechanisms involved in the oxidation of elemental mercury during polar sunrise? 2. Do the "mercury depletion events" contribute significantly to the atmospheric loading of mercury to the Arctic? 3. What are the emission rates of Hg from natural terrestrial sources in Norway? 4. What are the main species of Hg from industrial sources? Mercury pollutants are of increasing importance for the environmental quality in Europe and the rest of the world. Many of the mercury species are able to exist in both gas and condensed phases in the environment. Atmospheric transport and transformations are key processes for the loading of Hg in many regions, e.g. the Arctic. Airsurface exchange processes, such as re-emissions from sea surfaces and ground-air interactions are also of prime importance. For Hg, natural emissions also play an important role in the atmospheric cycling of this pollutant, although these sources have not been quantified. The project will carry out speciation of mercury during the "Arctic mercury depletion events". The global database on Hg fluxes has increased significantly the last ten years, but there are still large gaps. Flux measurements will therefore be carried out on different ground types in Norway in order to get an overview of emission/reemission from Norwegian areas. Until now emission measurements of mercury close to industrial sources have included almost exclusively elemental mercury. New information have however showed that more reactive species of mercury (RGM) are emitted from the antropogenic emission sources, forms that are much more dangerous to the ecosystems. The RGM emissions will be measured close to different anthropogenic sources. Despite intensive investigations over decades, many questions concerning trace metals remain unresolved, including their behaviour in soils and water and their ecological effects. In the past, much of trace metal research focused on total concentrations in soil and different soil fractions. Such information is valuable, but does not allow precise predictions of trace metal mobility and bioavailability. As a consequence reliable assessment of ecological risks of trace metals remains difficult. The project seeks to find quantitative relationships between trace metal speciation, mobility, bioavailability and effects in selected contaminated and uncontaminated (semi-)natural catchments in Odda County, Norway. Ecological effects of Cd and Zn and their speciation and bioavailability for living organisms in soils (plants and micro-organisms) will be assessed together with the transfer to surface water. The project will use newly developed biological and chemical analytical methods, along with mathematical modelling for predicting and assessing transport, effects of trace metals on microbes and plants, and ecological risk of metal contaminated soils. 13 Speciation, transport and bioavailability of Cd and Zn in contaminated terrestrial ecosystems. BIOMOD 14 Study of the physical properties and the chemical characterisation of particulate matter at Birkenes Prosjektansvarlig: Norges landbrukshøgskole,Institutt for planteog miljøvitenskap Prosjektleder: Mulder, Jan Professor Prosjektnr: 153370/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 1,000,000 2004: 1,000,000 2005: 1,000,000 Prosjektansvarlig: Norsk institutt for luftforskning Prosjektleder: Tørseth, Kjetil Prosjektnr: 153373/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 360,000 2004: 360,000 2005: 360,000 Main objective Quantify mobility, bioavailability and ecological effects on dominant plants and microorganisms of Cd and Zn in contaminated terrestrial ecosystems. The research will be carried out at contaminated and uncontaminated semi-natural catchments in Odda municipality, Norway. Specific objectives 1. Determination of concentrations of labile and free metal ions in soil solution using diffusive gradients in thin films (DGT). 2. Calibration of the equilibrium model WHAM for the speciation of trace metals in soils. 3. Assessment of relationships between trace metal speciation in soil solution and bioavailability (plants and micro-organisms). 4. Calibration of the CHUM model to estimate the transport of metals in the catchment and their transfer to surface water. 5. Assessment of the practical use of these techniques as tools in evaluating ecological risk of trace metal contaminated soils. Trace metals are major pollutants in the industrialized world affecting terrestrial and aquatic ecosystems. Main goal: The overall goal is to study the mass concentration of PM10 and PM1.0 , the particle size/number distribution as well as its chemical composition sampled at Birkenes. The information obtained will support current strategies in abating precursor emissions under the Convention on Long-Range Transboundary Air Pollution (CLRTAP). Specific goals: 1. Providing data for understanding gas to particle conversion (nucleation events) to improve the modelling of particle dynamics in the atmosphere. 2. Use of back trajectories to geographically locate the sources contributing to the particulate matter sampled at Birkenes 3. Attempts to apportion of emitting sources of particulate matter that contribute to the mass concentration sampled at Birkenes by using chemical characterisation and receptor analysis. Long-range transport of aerosols accounts for a significant portion of particulate air pollutant concentrations in Scandinavia. Accurate determination of the aerosol size distribution is an essential prerequisite for determining the transport distances and thus the geographic origin of particulate air pollutants arriving in Scandinavia from sources in continental Europe. Chemical speciation is required for pinpointing the types of sources from which the long-range transported aerosols originate. The use of a newly developed differential mobility particle sizer at the Birkenes site is proposed for obtaining detailed information about physical particle properties. More specifically, the project will measure the size distribution of long-range transported particular air pollutants over a wide range of size parameters and with a high temporal resolution. Using analytical techniques such as ICP/MS, IC, GC/MS, LC/MS and Thermal Optical EC/OC, several aerosol-related chemical parameters will be determined. Of special interest is the use of Thermal Optical EC/OC. To our knowledge, this technique has not been employed earlier for analysing ambient air particles collected in Norway. Air mass back trajectories and receptor analysis will be useful in order to geographically locate the sources of air pollutants, and to provide insights into the relationships among the various 15 The response of hyperbenthos, infauna and foraminifera to hypoxia in fjord-basins: Prosjektansvarlig: Havforskningsinstituttet,Senter for marint miljø Prosjektleder: Mortensen, Lene Buhl Forsker Prosjektnr: 153383/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 1,200,000 2004: 1,200,000 2005: 700,000 Objectives: Increase the knowledge of the effects of eutrophication on the bottom-fauna of fjords and establish controlling environmental factors. Sub-goals are: 1) Document the response of different components of the bottom-fauna in sill-basins to increased carbon flux and the resulting reduced oxygen concentration. To establish an eutrophication index based on the sensitive fauna-components. 2) Provide a documentation of the species richness of the bottom-fauna in 11 Norwegian fjords along the Skagerrak coast, which can serve as a baseline for monitoring the regional coastal biodiversity. 3) Identify general relationships between the basin characteristics and dynamics and bottom-fauna to make a model as a tool for prediction of fjord health. 4) Identify fjords that historically have experienced low oxygen concentrations through a retrospective study of the environmental conditions based on the foraminiferal fauna preserved in the sediment of the fjordbasins. A unique long time series of oxygen measurements exists from several Skagerrak fjords as part of an ongoing monitoring program. It reveals a clear decline after 1975 due to eutrophication. This is a large scale experiment that offers a possibility to get detailed observations on how the bottom fauna is affected. Today indicators of eutrophication are based mainly on infauna but, the fauna living at the sediment-water interface, "the hyperbenthos", is assumed to be particularly sensitive, however, the detailed knowledge of the response of this fauna group is sparse. The projeet will compare the "hyperbenthos", macro infauna, and foraminifera, together with environmental factors, of 11 sill-basins that are part of the unique monitoring program. Because the historical levels of oxygen in the bottom water at these localities differ a comparison of the bottom fauna wiIl produce detailed information on responses to hypoxia. In addition, a documentation of this fauna will provide a baseline for the monitoring of coastal biodiversity. Furthermore, it will add data that can connect the earlier observed correlation of both carbon-flux and faunadiversity with fjord topography and improve the existing carbon-flux sill-depth model by including a fauna component. Moreover, the fjords which naturally have experienced repeated situations of hypoxia will be identified by using the foraminifera in sediment cores as an archive of historical bottom conditions. 16 Guano: a carrier medium for persistent organic pollutants (POPs)? Prosjektansvarlig: Akvaplan Niva AS Prosjektleder: Dahle, Salve Direktør Prosjektnr: 153411/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2004 2003: 600,000 2004: 600,000 The main goal of the project is to assess the role of guano as a carrier medium for POPs from the marine to the limnic ecosystem. Subgoals are to: - elucidate seasonal variations in the contribution from guano in the freshwater system and to assess the uptake in the freshwater food chain. - include the contribution from guano into a quantitative model that models the uptake and transport of POPs through the food chain - gather new scientific results which can be used in the development of monitoring programmes for Arctic areas - summarise the results in scientific publications and a thesis that fulfil the requirements for the Doctor scientarium degree. The main goal of the project is to trace the transport of persistent organic pollutants (POPs) from the marine food web into the abiotic compartment of a lake system and further into the food web of the lake. Food web transfer and biomagnification of POPsin marine and freshwater food chains have been elucidated through a number of studies, but the possibility for transfer between different ecosystems through biological pathways has only recently been described. The goal of the project is therfore to study the role of guano as a biological transport medium for POPs. The project will be performed on Bjørnøya, in an area where previous studies have revealed high concentrations of POPs, both in a lake system (Lake Ellasjøen) and in guano samples from seabirds. Ellasjøen is heavily affected by seabird guano. Another lake on Bjørnøya, Øyangen, which is much less affected by seabirds, will be used as a reference site. The results produced will be used as input to a model where uptake and transport of POPs through the food chain is quantified. Levels of POPs (with main focus on "new hazardous chemicals") in the food chains in Ellasjøen and in the marine environment close to Bjørnøya have been mapped through a project funded by the Norwegian Research Council (project 135604/720) and the Norwegian Pollution Control Authorities. Some guano samples were also analysed through this project. The results obtained are very interesting and emphasises the importance of studying this biological pathway for POPs-transport more closely. 17 Time-dependent bioavailability and toxicity of pesticides to soil living organisms Prosjektansvarlig: Jordforsk Prosjektleder: Sverdrup, Line Emilie Postdoktorstipendiat Prosjektnr: 153444/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2006 2003: 491,250 2004: 565,250 2005: 565,250 2006: 416,250 The objectives of this project are I. to describe the temporal changes in bioavailability, biodegradability and toxicity of hyrophobic pesticides in soil based on changes in sorption characteristics. 2. to derive a model that predicts toxicity of hydrophobic pesticides to a soil invertebrate at changing exposure concentrations. To reach these objectives, it is important - to elucidate the influence of desorption kinetics on the uptake rate of pesticides in soil invertebrates. - to describe the effect of sorption on biodegradability of pesticides. · to clarify the relationship between exposure and effect on soil invertebrates. · to integrate sorption, biodegradation and leaching in exposure models and link tissue concentrations to toxicity for a soil invertebrate. Soil sorption is a key parameter controlling the fate and ecological effects of pesticides. Recent monitoring data show that several pesticides are more persistent than expected, and that non-target exposure is likely to occur. Thus, the current risk assessment procedures often fail to describe environmental risk properly. One of the main problems associated with the current guidelines on risk assessments is that the exposure and effect assessment is based on total contaminant concentrations instead of the soil-specific bioavailable fraction of a compound. By linking sorption, bioavailability and ecological risk, the project seeks to improve exposure and effect assessment of two pesticides in particular, and on organic compounds in general. By relating temporal changes in sorption behaviour to changes in biodegradation, as well as bioaccumulation in earthworms, the influence of sorption on these processes will be revealed. A model will be developed that predicts toxic effects under changing exposure concentrations, and this model will then be parameterised and tested in mesocosm experiments. In addition, a simple and promising tool for determining bioavailability: non-exhaustive extraction with ^Xcyclodextrine, will also be evaluated. 18 Increased N removal in constructed wetland filters use of stable nitrogen isotopes to determine factors controlling denitrification /DNRA Prosjektansvarlig: Jordforsk Prosjektleder: Søvik, Anne Kristine Forsker Prosjektnr: 153448/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-3.12.2005 2003: 550,000 2004: 550,000 2005: 550,000 Examine N-removal processes in constructed wetlands such as denitrification and dissimilatory nitrate reduction to ammonium (DNRA). Stable N isotopes will be used to examine the environmental factors favouring the processes. · Use batch studies to examine relevant processes for N retention in wetland filter material, as well as identifying environmental factors influencing these processes · Study N-processes coupled to transport in a meso-scale constructed wetland · Evaluate whether use of natural isotopic fractionation of N isotopes may be used as a method for determining denitrification rates in constructed wetlands Release of nitrogen and phosphorus to lakes, rivers and coastal areas constitutes the main risk for reduced water quality and eutrofication. The most important antropogenic sources for nitrogen and phosphorus compounds in Norway are municipal wastewater, runoff from agricultural areas, landfill leachate and loads from the industry. Nitrogen removal from wastewater is currently demanded in some cities and we expect requirements to come for non-urban areas e.g. in connection with the new requirements of the Water Framework Directive. In non-urban areas, constructed wetlands may be a feasible and cost-efficient method for wastewater treatment. Research at Jordforsk related to nitrogen removal in constructed wetlands indicates that processes of relevance for removal and buffering of nitrogen are besides the nitrification-denitrification process, also dissimilatory nitrate reduction to ammonium (DNRA) and ammonium sorption. With denitrification, nitrogen is permanently removed from constructed wetlands, however, the greenhouse gas N2O may constitute a substantial part of the emitted gases. DNRA on the other hand is an unfavourable process as nitrate is reduced to ammonium instead of being denitrified. It is not yet clear which environmental factors that favour the different processes in constructed wetlands. In co-operation with an interdisciplinary research team the project will use isotope studies to examine the environmental factors favouring the different processes, in order to optimize the removal of nitrogen in constructed wetlands, while at the same time minimising the emissions of N2O. 19 Bioavailability and effects of organochlorine contaminants in relation to seasonal lipid cycles in arctic fox Prosjektansvarlig: NINA,Arktisk økologi Prosjektleder: Jørgensen, Even Seniorforsker Prosjektnr: 153484/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 626,000 2004: 705,000 2005: 385,000 Overall goal: Study the influence of natural winter emaciation in an arctic top-predator on organochlorine contaminant tissue distribution, bioavailability and biological impact. Partial goals: I. Quantify OC distribution between 'insensitive' storage tissues (adipose tissue), blood (transport medium), and sensitive tissues (liver, brain, gonads) in relation to seasonal emaciation. 2. Determine the effect of OC tissue distribution (see point I.) on OC bioavailability (i.e. hepatic CYP1A biomarker responses). 3. Assess possible effects of natural OC body burdens on adrenal steroidogenesis and plasma hormone levels in fat and lean arctic fox. Arctic animals utilize periods with high food availability for feeding and lipid deposition, whereas they rely on stored lipids during unfavourable periods. Hence, many arctic inhabitants exhibit profound seasonal cycles of fattening and emaciation. In the Arctic, feeding is associated with fat deposition and contaminant accumulation. When lipids are mobilized, accumulated contaminants are released into the circulation. Consequently, blood contaminant concentrations may increase markedly and result in a redistribution of the contaminant(s) from "insensitive" adipose tissues to sensitive organs, and increased contaminant bioavailability. Such variations complicate interpretations of pollutant toxicity, both in effect studies and in monitoring programs, and remain an important future research area. The project will use arctic fox (Alopex lagopus) as a model species for investigating tissue distribution and bioavailability of organochlorine contaminants (OCs) in relation to natural variations in lipid status (field study). These data will be supplemented and validated through a contamination study with blue fox (A. lagopus), where the seasonal changes in lipid status of wild fox are simulated in the laboratory. In the field and laboratory study, possible effects of OCs on steroid hormone synthesis, and plasma levels of hormones, vitamin E and retinol will also be assessed. 20 Mercury in lake sediments; trends in fluxes, geographical pattern and sources Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Skjelkvåle, Brit Lisa Forsker Prosjektnr: 153515/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.4.2003-31.12.2005 2003: 625,000 2004: 600,000 2005: 350,000 Identify historical and recent trends in the supply of atmospherically deposited mercury into lakes in Norway with respect to rates, geographical patterns and pollution sources. Sub-goals - Reveal the temporal and geographical variations in the atmospheric depositions of mercury and other trace elements in Norway by analysis of dated lake sediment cores -Determine the ratios of stable mercury isotopes in the dated sediment cores and in different source materials for atmospheric mercury pollution (coal, elemental mercury, non-ferrous ores etc.) - Elucidate the historical and recent sources of mercury pollutants in lake sediments by comparing the stable mercury isotope ratios in dated strata with the ratios in potential source materials. The analysis will focus on the influence of long-range atmospheric transport versus emissions from local smelters and process industry Mercury is a ubiquitous contaminant because of the dominantly atmospheric pathways by which it is transported to regions far from the emission sources. Lake sediments are suitable as environmental archives for tracing the history of mercury depositions, as airborne mercury deposited on the lake surface, and supplied from the catchments, are likely to be scavenged by organic particles and deposited in the sediments. The project will examine historical trends and geographic variations in atmospheric mercurydepositions by analysis of dated lake sediment cores. Resent results indicate that natural mass dependent fractionation of mercury isotopes may give rise to small, but significantly distinct isotopic signatures in different environmental samples. This offers the opportunity for using isotope ratios in source-oriented studies of mercury pollution. The project will use isotope analyses to examine the historical and recent sources of atmospheric mercury pollution. The ratios of stable mercury isotopes in dated sediments will be compared with the ratios of source materials of atmospheric mercury pollution (coal, elemental mercury, non-ferrous ores). The isotope analyses will be done by a high-resolution mass spectrometer (MC-ICP-MS) in co-operation with a scientific group at Trent University, Canada. The project will especially focus on the influence of long range transboundary atmospheric mercury pollution (main source is burning of coals) versus local emissions from non-ferrous smelters and other process industry. 21 Bioaccumulation, ecotoxicology and biomarker responses of new and old POPs in a marine ecosystem;.. Prosjektansvarlig: NINA,Avd. for terrestrisk økologi Prosjektleder: Nygård, Torgeir Forsker Prosjektnr: 153560/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 853,000 2004: 863,000 2005: 705,000 1) To investigate the levels of ‘new’ and ‘old’ POPs along a gradient from a (polluted) urban fjord site to a remote (clean) coastal site. 2) Method adaptation and optimisation for the implementation of new compounds such as metabolites of brominated flame retardants, chlorinated naphtalenes and alkanes, and perfluorinated organic compounds into standard methods for POP analysis. 3) study bioaccumulation rates of different POPs in two parallel food chains. 4) evaluate the ecotoxicological implications of the observed levels of POPs and biomarkers in relation to growth and reproductive success of model species, in particular the Shag. The research project will make use of two simple and representative food-chains to study bioaccumulation and biomagnification of new and little studied organic pollutants such as brominated flame retardants (BFR), chlorinated alkanes (PCA) and synthetic musks, as well as PCBs, DDE, HCH and HCB. Therefore, during the project, biological samples in marine food chains (Blue mussel -Eider, Saithe and Shag) will be collected in three carefully selected localities, along a gradient from "polluted" to "pristine". This will also allow an evaluation of the importance and magnitude of local vs. long-range transported load of POPs. Basic data on POP levels in seawater will be obtained during the project by the use of semipermeable membrane devices (SPMD). Two of the sites are seabird colonies with long and ongoing series of population and reproduction studies, and a carefully designed study of POP levels, biomarker responses, growth and breeding achievements of a fish-eating seabird, the Shag, will make ecotoxicological interpretations possible. The results will deepen and broaden the information gathered during the study under ongoing projects performed by the same research group. The analytical achievements will be implemented in new and better procedures for existing and future research and monitoring programs. 22 Radioactive dose assessment improvements for the Nordic marine environment:... Prosjektansvarlig: Statens strålevern Prosjektleder: Gwynn, Justin Seniorforsker Prosjektnr: 153568/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 1,000,000 2004: 1,000,000 2005: 1,000,000 The principal objective is to further constrain dose assessments for the Nordic marine environment through statistical and experimental examination and reassessment of abiotic and biotic parameters of a pre-existing dose assessment box model. This will be achieved through:- The determination of technetium-99 (99Tc) levels and time series in pelagic and benthic food webs in Norwegian waters. Improved understanding of time-dependent distribution coefficients (KD) and concentration factors (CF) of 99Tc in key marine organisms and the removal of contaminants during alginate industrial processing. Improvement of the NRPA box model by the integrated analysis of model hindcasts for 99Tc dispersion, the introduction of selectable flow fields and novel and reassessed abiotic and biotic parameters and a critical analysis of current radionuclide monitoring designs. Radioactivity in the Arctic environment is a central topic within environmental pollution issues. The project (acronym "RADNOR") includes model and monitoring assessments and improvements, several hypothetic case studies with sources of different character and location, dose calculations and use of realistic climatic background scenarios in order to assess corresponding consequences for transport of radioactive pollutants. The measurements that are used in RADNOR origin from fieldwork and monitoring performed by the Norwegian Radiation Protection Authority. The models central in RADNOR are a 3-D hydrodynamic oceanographic model, calculating radionuclide transport pathways and concentrations, and an oceanographic box model, which gives average radionuclide levels on a longer time scale. RADNOR consists of three main components: - A first part, dealing with model hindcasts and observations for spreading of technetium-99 from the Sellafield nuclear reprocessing plant during the 1990s; - Part 2, containing working packages on improvements of the box model; and - Part 3, applying the models for a selection of scenarios taking both different climate forcing situations and different kinds of accidental discharge scenarios into account. From the model outputs, doses to man and environment will be calculated resulting in a valuable database for use within environmental management and for decision makers. 23 Triclosan - A New POP? Prosjektansvarlig: Norsk institutt for luftforskning Prosjektleder: Schlabach, Martin Seniorforsker Prosjektnr: 153688/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2004 2003: 700,000 2004: 800,000 Within the proposed project a first assessment ot concentration levels, fate and environmental risk of Triclosan in abiotic and biotic Norwegian environmental samples will be performed. It is planned to -develop and validate a reliable trace analytical method based on gas chromatographic (GC) separation and mass spectrometric (MS) detection for qualitative and quantitative determination of triclosan in air, water and biota samples. -provide first evidence about the presence and distribution of triclosan in the Norwegian aquatic environment. -study seasonal variations due to the photochemical degradation of triclosan -perform an environmental risk analysis for triclosan -disseminate the result of this project to authorities and public There is a growing concern about the increasing use of triclosan, due to its ability to lead to antibiotic resistance in micro-organisms and due to other undesired environmental effects. Triclosan has been used as an effective antiseptic in cosmetics, soap, toothpaste and plastic for kitchens and table utensils. Triclosan is a relatively stable, lipophilic compound and bioaccumulate. Environmental occurrence of triclosan has been reported in samples of wastewater, surface water, sediment and fish. Within the project a reliable trace analytical method will be developed and validated together with the project partners in Sweden and Switzerland. A first assessment of concentration levels, fate and environmental risk of Triclosan in abiotic and biotic Norwegian environmental samples will be performed. Samples of wastewater, surface water, mussel and cod from the Oslo fjord area and surface water and fish from the lake Mjøsa will be analyzed. In order to evaluate the potential peculiarities under Northern environmental and climatic conditions a study of the seasonal trend in surface water will be performed. As an integrated part of the dissemination strategy the project will be finished with an open workshop bringing together the project partners from NILU, NIVA, ITM (Sweden) and SFRS (Switzerland), relevant authorities and other interested organizations. 24 Effects of pesticides on endocrine function and development in amphibians Prosjektansvarlig: Biologi, Institutt for,Norges teknisknaturvitenskapelige universitet Prosjektleder: Jenssen, Bjørn Munro Professor Prosjektnr: 153698/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.7.2003-31.12.2005 2003: 150,000 2004: 150,000 2005: 150,000 Establish an amphibian model using Rana temporaria as a model species for examining endocrine disruptive effects of pesticides on development (metamorphosis, sexual differentiation, growth) and endocrine homeostasis in amphibians. Eggs and adults will be exposed to pesticides (DDT, permetrin and fenitrotion) to evaluate to which extent these pesticides may have endocrine disruptive properties that may affect popullations of amphibians. To assess the impact of combined effects, eggs and adults will also be exposed to a combination of pesticides and UV-B radiation. Effects will also be studied in individuals from naturally high and low exposed populations. Pesticides can be an important contributing factor to the world-wide decline in amphibian populations. The aim of the project is to examine to which extent pesticides affect development (metamorphosis, sexual differentiation and growth) and endocrine function in amphibians, and thereby assess the contributing effect of pesticides to the amphibian decline. Rana temporaria is chosen as a model species. Increased UV-B radiation is another factor that has been suggested to be a contributing factor, and the study will focus on the combined effects of pesticide and UV-B exposure. Studies will be conducted through experimental exposure of adults and eggs, and individuals from polluted sites and from control sites will be collected and assessed in relation to the experimentally exposed individuals. Effects will be examined biometrically, anatomically and histologically, and by studying thyroid and sex hormone homeostasis, retinoid, thiamin and tocopherol status. 25 Perfluorinated aliphatic surfactants and airborne fluorochemicals in Norwegian environmental samples Prosjektansvarlig: NILU - Tromsø Prosjektleder: Berger, Urs Forsker Prosjektnr: 153740/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2003-31.12.2005 2003: 520,000 2004: 725,000 2005: 540,000 A first assessment of environmental risk and concentration levels of perfluorinated organic compounds (FOCs) in abiotic and biotic Norwegian environmental samples will be performed. Sub-goals 1. Develop and validate reliable trace analytical methods for qualitative and quantitative determination of FOCs in water, air and biota samples. 2. Provide first evidence about the presence and distribution of FOCs in the Norwegian environment. 3. Gain better insight into potential toxicological and ecotoxicological effects caused by man-made FOCs and their transformation products. 4. Provide data and expertise to national decision-making institutions leading to adequate decisions concerning production and use of FOCs in Norway. Fluorinated organic compounds (FOC) are used for a wide range of industrial applications. The presence of perfluorinated aliphatic surfactants in environmental samples including biota from remote areas and of airborne polyfluorinated alcohols in air samples has recently been reported. The lack of pertinent data and information on the deviating properties of these newly emerging persistent hazardous substances presents urgent need for elucidation. The exceptional physical properties of fluorinated compounds ask for completely new sample clean-up and analysis techniques. A currently on-going project gave very promising results concerning separation and detection of the target analytes in ultra-trace levels by liquid chromatography coupled to different mass spectrometric techniques. The project intends to optimise and adapt these methods to the requirements of analysis of a comprehensive set of environmental samples such as air, water and marine biota. Furthermore, different toxicity tests such as membrane studies from fish brains and free radical and cell death studies with primary cell cultures will be performed. The toxic effects can be directly correlated with those of the well investigated PCBs and brominated flame retardants. Finally, the scientific findings of the environmental monitoring and toxicity testing will be given to political decision-makers. 26 Brominated flame retardants: Study of environmental fate and synergistic toxic effects with a special focus on the Norwegian environment Prosjektansvarlig: Norsk institutt for luftforskning Prosjektleder: Schlabach, Martin Seniorforsker Prosjektnr: 159116/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 1,050,000 2005: 1,050,000 Study of source, transport, levels and effects of brominated flame retardants with emphasize on the Norwegian environment. Task 1: Study on spatial distribution and long-range atmospheric transport of brominated flame retardants Task 2: Study the biomagnification processes of BFR in the pelagic food web of Lake Mjøsa- a deep Nordic lake 2.1 Determine particulate and free fraction of BFR in lake water. 2.2. Estimate the sampling characteristics of SPMD with respect to different BFR congeners: use of SPMD to detect spatial variation in concentrations of BFR in lake water. 2.3. Determine the concentration of BFR in major invertebrate prey groups. 2.4. Estimate the net trophic transfer efficiency of BFR between major compartments in the pelagic food web. Task 3: In vitro and in vivo study of neurotoxic and immunotoxic effects of BFR in fish and rodents The knowledge of sources, levels, trends, transport and toxic effects of brominated flame retardants (BFR) is still very limited. Based on our findings of extraordinary high levels of BFR in Lake Mjøsa, this project will study the behaviour and ecotoxicological impact of BFR on environment. Major objectives will be spatial distribution and long range transport of BFR, biomagnification processes of BFR in a pelagic food web of Lake Mjøsa, and in vitro and in vivo study of neurotoxic and immunotoxic effects of BFR in fish and rodents. Human and wildlife animals are often exposed to high concentrations of different environmental toxins. The project will have especially focus on possible synergistic toxic effects of BFR in combination with the major environmental contaminants PCB and methyl-mercury. As a consequence of this improved understanding, authorities will be furnished with a better basis for decisions such as reduction or complete ban of these or similar compounds. 27 Functional role of macrofauna on contaminated sediments and the potential of fauna recovery following sediment remediation Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Olsgard, Frode Forsker Prosjektnr: 159200/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 475,000 2005: 400,000 The principal objective The overall objective is to establish cause and effect relationships between pollutants and macrobenthic fauna structure and function in order to predict possible improvements in the ecological health following remediation of strongly polluted marine sediments. Project sub-goals: - Investigate the link between pollution and the functional role of the benthic communities and identify the most important organisms for ecosystem functioning -Investigate the relationships between the chemical and ecological status of selected polluted coastal and offshore areas in order to generate plausible cause and effect hypotheses for further experimental testing in field experiments and mesocosm studies -Provide a basis for producing ecologically based environmental health classification systems In a number of Norwegian coastal and fjord sites, bottom sediments are heavily contaminated by micropollutants from anthropogenic discharges. Prevalent contaminants are metals, PAH, PCB, dioxins and TBT. The sediments may represent significant sources to contaminants in ambient water and biota. Presently Norwegian environmental authorities consider to implement rather expensive measures to clean the sediments in the most polluted areas. Sediments are complex dynamic habitats in which the fauna interplay with physical and chemical processes. The present study aims at assessing the functional role of benthic communities on contaminated sediments and estimate community recovery following sediment remediation. This will be approached through 1)identifying links between chemical pollutants and key structural and functional factors of benthic species communities, and 2) evaluting different methods for estimatig faunal recovery. Links between faunal function and comtaminants will be assessed from existing data in databases combining information about species composition with functional traits such as reproduction, life duration, feeding habits, body form and mobility. Methods for estimating recovery will be based on comparisons with reference areas, faunal changes along gradients and theoretical approaches combined with functional traits. Field investigations will be carried out at localities with severe sediment pollution to supply data and test predictions. The product seeks to develop a conceptual framework for estimating recovery. The results will be of general importance for risk assessments and management of contaminated sediments and is relevant to the EU water frame directive. 28 A flexible, integrated tool for management of contaminated sediments 2 Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Næs, Kristoffer Forskningsleder Prosjektnr: 159214/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 1,350,000 2005: 1,350,000 The principle objective is: -To develop a flexible, user-friendly tool for management of contaminated sediments. To achieve this, the specific scientific objectives are: 1. Develop a flexible modelling tool that can be used to describe the fate and food chain accumulation of contaminants in multiple Norwegian aquatic ecosystems 2. Enhance the acceptability and capability of the model in decision support for managing contaminated sediments 3. Develop a framework for cost-benefit analysis under uncertainty for the evaluation of scenarios for clean-up of contaminated sediments Developing strategies to manage contaminated sediments has been identified as one of the major environmental challenges facing the European Community and Norway. To that end, Norway has newly launced comprehensive action plans. Given the complexity, question of utilitarian value and cost related to clean-up measures, tools for decision support are imperative. To provide stakeholders with the tools to assess the risks associated with contaminated sediments, we need to formulate a predictive model,which should be based on easily obtainable properities of any given system and pollutant molecule. It should be an integrated model that incorporate the fundamental processes involved in sediment - water transfer of POPs and predict the fluxes of bioavailable POPs into the overlying waters, see these in relation to other sources and include food chain accumulation. The process-based model should be able to make predictions of fluxes and resulting water concentrations of any given POP for any given fjord/bay over different time scales into the future. Given the nature of the cost involved in remedial actions, there is also a need to develop methods for economic cost-benefit analysis. We here propose to develop a user-friendly tool for management of contaminated sediments. 29 Pollution induced modulation of sex steroid transport and cellular responses - POLLMOD Prosjektansvarlig: Norsk institutt for vannforskning Prosjektleder: Tollefsen, Knut-Erik Forsker Prosjektnr: 159243/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 370,000 2005: 390,000 The objective is to develop methodology determine whether chemical interference and modulation of SBPassisted transport of sex steroids represents a novel mechanism for endocrine disruption and clarify how this mechanism interacts with traditional estrogen receptor (ER)- mediated endocrine disruption. Studies will encompass traditional and priority pollutants like BFR, PFOS and PPCP. The objectives of the project will be achieved by: 1 in vitro determination of direct interference with the SBP 2 in vitro determination of interaction with SBPmodulating and ER-mediated mechanisms for endocrine disruption 3 in vitro assessement of the endocrine disrupting potential of selected chemicals Attempts to link adverse health effects in wild fish populations to the exposure to endocrine disruptors are complicated by the low potency of many of these chemicals. The low estrogenic potency of these chemicals would require either exposure to very potent unknown endocrine disruptors, environmental mixtures of several active compounds, additional mechanisms of endocrine disruption or co-operation between multiple mechanisms for toxic effect. While classical mechanism of endocrine disruption an mixture toxicity is well documented in literature, studies on novel mechanisms of endocrine disruption and cooperative action between multiple mechanisms are highly warranted. This applies in particular to studies encompassing high priority environmental pollutants like brominated flame retardants (BFR) perfluorinated organic chemical (PFOS) and pharmaceutical and personal care products (PPCP) where knowledge of toxic mechanisms and potential is limited. POLLMOD will investigate novel mechanisms of endocrine disruption involving the plasma sex steroidbinding protein (SBP) through use of a combined approach using fish in vitro and in vivo experiments. Methods developed will be used to assess the endocrine disrupting potential of traditional and "new" environmental pollutants and is anticipated included in an environmental monitoring "toolbox". 30 Integrated risk assessment for the transport of particles, nutrients and pesticides in agricultural catchments INTRA Prosjektansvarlig: Jordforsk Prosjektleder: Øygarden, Lillian Prosjektnr: 159255/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 1,500,000 2005: 1,500,000 The overall goal of the project is to develop/conduct an integrated (combined nitrogen, phosphorus, soil erosion and pesticides) pollution risk assessment for optimal implementation of measures to critical source areas. The subgoals are: 1. Identification of relative critical source areas for low/high losses of soil, nutrients and pesticides. 2. Development of risk assessment indices for N, P and pesticides for a case area (The Skuterud catchmen). 3. Defining pathways from source via the soil to surface waters. 4. Incorporate in the soil erosion risk assessment also other erosion forms than sheet erosion. 5. Development of an integrated tool for management of mitigation strategies. There is a need to develop an integrated management strategy at the catchment scale that jointly include the spatial variation in risk of nutrient, particle and pesticide losses. This project seeks to develop such an integrated approach, based on risk assessment indices for erosion, P loss, N loss and loss of pesticides. The project will be based on existing data within the JOVA-programme as well as other related projects, e.g. PhD.- project on development of a P index, empirical nitrogen models from work in relation to the 5th North Sea conference. Some additional studies will be carried out to highlight special issues, especially at the catchment scale. The indices in themselves provide a categorisation of the edge-of-field risk of loss and additionally the catchment scale approach will be represented in form of e.g. connectivity, stream bank erosion and retention. The output from this project will be a pilot integrated index for a catchment, which will be useful for end-users implementing differing management strategies for different areas of the catchment. 31 POP transfer through Arctic marine food webs - further model development and data analyses Prosjektansvarlig: Norsk Polarinstitutt Prosjektleder: Borgå, Katrine Forsker Prosjektnr: 159417/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.3.2004-31.12.2005 2004: 685,000 2005: 594,000 i) Theoretical modelling of food web transport of pollutants - Continue improvement of the Campfens Mackay (1997) model by additional development and tests of chemical, environmetal and organism parameters Complete a multi-species mass-balance unsteady-state food web model by including numerical solutions to change the present steady state model to a non steady state-condition - Further develop a user-friendly modelling tool for research and management purposes in terms of scenario building ii) Analyse Canadien and European Aarctic marine fod web organochlorine datasets jointly to identify and explain semi-circumpolar patterns. The proposed post doctoral project consist of two interlinked parts which will study in details marine food web accumulation of contaminants in Arctic marine ecosystems by the use of already existing organochlorine data in Arctic marine food webs -Barents Sea and North Water Polynya - . Both parts are different approaches to study the overall aim: to understand which factors are important in the bioaccumulation of organic pollutants in marine food webs. Both parts require and will be conducted in collaboration with international scientists. Part i) to further develop and adapt a steady state mass balance food web model (Campfens and Mackay 1997) to make it applicable to Arctic marine ecosystems with an unsteady state assumption. The model will be available for research and management purposes and can be used to identify variables of importance for bioaccumulation in Arctic marine food chains, ii) to analyze Canadian and Norwegian food web data sets jointly to properly investigate the semi-circumpolar contaminant distribution in invertebrates, fish, seabirds, seals and polar bear. 32 Killer whales in Norway transfer, sex - and age-specific accumulation and biological responses of contaminant mixtures Prosjektansvarlig: Norsk Polarinstitutt Prosjektleder: Wolkers, Hans Seniorforsker Prosjektnr: 159432/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2004 2004: 120,000 The proposed study aims to investigate exposure of Norwegian killer whales to "old" and "new" contaminants, contaminant transfer from prey to predator, contaminant-specific accumulation and biomarker responses. In this proposal we ask for resources to analyze killer whale tissues, sampled in November 2002, for a broad range of contaminants, including new compounds, as well as biomarker responses. Subgoals: - Assess contaminant-specific food chain transfer and accumulation in Norwegian killer whales. - Assess the biological response to contaminant exposure (CYP 1A activities) in relation to contaminants in food and blubber. Marine predators, like seals and whales are exposed to high levels of contaminants, including PCBs and pesticides. However,in recent years there is growing concern about the increase of "new" compounds, like polybrominated flame retardants(BFRs), in the environment. Recent studies have indicated that these "PCBs of the 21 st. century" double their concentration every 5 years. Killer whales worldwide hold the gloomy record as most polluted marine mammal in the world. Due to their high trophic level these animals can be considered as ultimate indicators of marine ecosystem health, but surprisingly, Norwegian killer whales have not been subject to any ecotoxicology-related studies. Ecological as well as physiological factors make killer whales particularly sensitive to contaminant exposure and research on this high profile top predator is desperately needed. The proposed study reaches beyond the traditional measurements of levels. It addresses for each contaminant group: 1) the degree and type of exposure with emphasis on new compounds;2)transfer in the herring-killer whale link of the marine food web; 3)bioaccumulation and metabolism of "old" and "new" compounds; 4) contaminant-induced biological responses (CYP1A assays). 33 Long-term trends and ecological effects of pollutants in a tawny owl population in central Norway Prosjektansvarlig: NINA,Arktisk økologi Prosjektleder: Bustnes, Jan Ove Seniorforsker Prosjektnr: 159435/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 700,000 2005: 750,000 Principal objective: Examine fluctuations and potential ecological effects of various pollutants, and develop improved monitoring methods for terrestrial top-predators, by using a long-term data series on the tawny owl. Sub-goals: - Document fluctuations in levels of heavy metals and organic pollutants in central Norway during the 1980s and 1990s. -Examine the occurence and trends of less studied environmental contaminants in central Norway during the last 20 years. - Investigate if population dynamics of tawny owls are affected by pollutants, and how such effects are influenced by natural stress factors - food abundance and climatic conditions . - Use long term data to develop new methodologies for monitoring of pollution in terrestrial top-predators, to save resources for data collection. Various pollutants, including heavy metal and organochlorines, have been of great concern in Norway, but long term data sets on wildlife likely to be affected by such pollutants have been lacking. Here we propose a study of levels, fluctuations and possible ecological effects of different pollutants in a tawny owl (Strix aluco) population in central Norway, by using a long-term data series. The data are individual based, and tail feathers have been collected presently from 193 female owls since 1986 (514 feathers). In addition more than 300 eggs have been collected in the same period. Simultaneously measures of reproductive output adult survivel and diet have been recorded. The data will be analysed using recent developments in statistical modelling which will enable us to extract the effects of pollution from natural environmental variation. This data series provide a uniqe opportunity to document changes in pollution levels, occurrence of new contaminants and effects of pollution over a period when management effort to reduce pollution has been very high. In addition it will enable us to develop an improved sampling design for monitoring of pollutants in terrestrial top-predators. 34 Controls and fate of springtime atmospheric mercury deposition in the Arctic Prosjektansvarlig: Norsk institutt for luftforskning Prosjektleder: Berg, Torunn Seniorforsker Prosjektnr: 159437/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 982,000 2005: 402,000 The main aim is to study the controls and fate of springtime atmospheric mercury deposition in the Arctic. The following specific questions will be addressed: 1. What chemical species comprise reactive gaseous mercury?. 2.What are the sea ice processes leading to the release of photolyzable bromine? 3. To what extent is the snowpack a sink for reactive gaseous mercury and a source of elemental mercury? 4. What is the biotic fate of the deposited mercury?. 5 What are the climatic variables that control mercury deposition rates? 6. What are the mechanism behind the high mercury concentrations in moss wrowing at the Norwegian Arctic coast. The discovery of the springtime atmospheric mercury vapour depletion phenomenon at Alert in the Canadian Arctic stimulated a vigorous research effort in six circumpolar nations and other countries with a keen interest in preventing pollution of polar regions. The last 4 years have demonstrated that atmospheric mercury depletions/deposition episodes (AMDEs) occur perennially, not only at Alert but also at other locations in the Arctic: Alaska, Svalbard, Greenland, Russia, Hudson Bay and in Antarctica. While the existing of this ecologically important phenomenon in cold environments is now accepted by the scientific community, many uncertainties remain in our understanding of AMDEs. A workshop in Toronto, 2002, brought together 40 scientists on this subject from eight countries. Its primary objectives were to share the knowledge pertaining to AMDEs, review and discuss outstanding research questions, examine opportunities for future collaborations, and initiate preliminary planning of prospective studies to fill the existing knowledge gaps. Attendees concluded with a compilation of high priority research questions related to this polar phenomena. The present project consists of three sub projects, all aiming on answering these questions. The sub prosjects are: International mercury study at Barrow, The fate of atmospheric mercury at Ny-Ålesund and Mercur in mosses at the arctic coast of Norway. 35 Environmental Noise 20042005 Prosjektansvarlig: SINTEF Tele og data,Telecom and Informatics Prosjektleder: Gjestland, Truls Seniorforsker Prosjektnr: 159459/S30 Bevilgningsperiode og finansiering fra Norges forskningsråd: 1.1.2004-31.12.2005 2004: 2,800,000 2005: 2,800,000 The proposal outlines plans for the continuation of a comprehensive cross-institutional research program on environmental noise. Five Norwegian institutions with a leading role in noise research have established a research consortium. They will act as a resourceful partner for the Norwegian Research Council. The plans are in compliance with the targets for noise research set forth by the Research Council. The plans include the following elements: • description and analysis of the present noise situation with respect to both physical, sociological, and psychological aspects of environmental noise as a basis for predicting future changes. • description and analysis of major noise sources, in particular road traffic noise • models for prediction and optimization of the effect of planned or implemented noise reduction measures in a complex noise environment. • models for cost-benefit analysis of noise reduction measures, and for complex situation where noise abatement is but one of several factors implemented to improve living conditions in a community. • increased noise competence and awareness on all levels of public administration • international co-operation and networking. More details on main targets are presented in the annex: Proposal for a cross-institutional research program, phase 2. Special attention will be given to community noise models, neighborhood soundscapes, and noise annoyance and sleep disturbances in urban areas. In this phase 2 of the project, there will also be an emphasis on noise reduction strategies, and studies on the noise generation mechanisms of vehichles and vehichle/road interaction. This research program will provide knowledge to assist the authorities in reaching the target of 25 percent decrease in noise annoyance within 2010, and to strengthen the Norwegian noise research community. These main objectives can be reached by: • Developing tools and methods for measuring and predicting noise annoyance, • Studies aimed at understanding physiological, sociological, and psychological factors influencing noise annoyance, • Designing and developing noise abatement strategies, and models for cost-benefit analysis of noise reduction measures •Providing know-how and competence on all levels.
