Agricultural Pesticides and Human Health Author: Bridget Hicks This case study is part of a collection of pages developed by students in the 2012 introductory-level Geology and Human Health course in the Department of Earth Sciences, Montana State University. Learn more about this project. A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest (epa.gov). Pests can be defined as any organism that causes plant diseases. Agricultural pesticides are then those chemicals that are used by farmers to prevent the effectiveness of the pests on the growth and productivity of agricultural crops. Introduction Pesticides are either restricted or unclassified. Restricted means it can cause harm to humans or the environment. Unclassified refers to all other pesticides. Pesticides are made up of active and inert ingredients. There are certain labeling requirements for the commercial distribution of products that used agricultural pesticides. The active ones are those which do the damage to the pest, federal law mandates that these ingredients be clearly labeled on the packaging. Inert ingredients are not required to be labeled as they do not cause harm, they are usually present as a solvent in the solution. (inert ingredients are not necessarily non-toxic). All pesticides must be registered with the EPA before they can be sold or distributed. There are many tests and requirements concerning the potential effects of the pesticides in order to be approved.

They were of great importance in saving the United States' potato crops during the 1940's from insect and fungal pests, as well as controlling the boll weevil in El Salvador in 1953 (Monosson, 1). Yet many times their detrimental effects outweigh the positive ones. Pesticides can be extremely hazardous to the human body and other living organisms, as they are designed to be a poison. Here is a link to the EPA's webpage about agricultural pesticides. Sources of Agricultural Pesticides Pesticides became common after the second World War as part of the war effort was scientific research into a way to end hunger, i.e. pesticides and the increasing productivity and availability of food production with their help. Currently an estimated 3.2 million tons of pesticides are used each year. Pesticides are wasted in environments where the farmer has little knowledge or care for the detrimental effects of the pesticides. Without regulations and enforcements these pesticides can easily be spread farther than their intended area. This is especially common in developing countries. With misuse the pesticides can easily be picked up by the rainwater and washed into the streams as runoff.

Transport of Agricultural Pesticides Pesticides can be transported to humans or other organisms in a variety of ways. It is near to impossible for the pesticide to only affect its targeted crop. -Wind is one transportation method. The wind picks up the pesticides and can blow them onto other farms or into rivers. -It can be absorbed into the soil and then taken up by other organisms or can contaminate the surface and groundwater that run over/through it. - Pesticides are then absorbed by the plants which is detrimental to the growth of the plants. - That which is not absorbed usually remains on the surface and flows into streams as surface runoff. It is dissolved into the water and then can be taken in by plants and animals. The streams would then be considered a reservoir of pesticides with a relatively high abundance level. Bioavailability Pesticides frequently enter the world's surface and groundwater through either point source (direct locations where excess pesticides spill, or non-point sources, where the pesticides enter the streams through wind flow, precipitation, runoff, and leaching. These pesticides can accumulate in a surface water source such as a lake, stream, or pond, they can also leach down and become integrated into the groundwater reserves such as reservoirs. Pesticides enter the food chain through the direct application of the substance to the plants themselves by humans. Once they are absorbed by the plants or animals which eat the plants they become residue. There are maximum residue levels for crops and animals. They can also be taken in when an organism takes in the water which contains the runoff and dissolved pesticides. This can be further extended to the human who eats the fish. An easier way for humans to ingest pesticides is directly through contaminated drinking water from those polluted streams. Impacts on Human Health An estimated 2.2 million people are at risk due to exposure from agricultural pesticides, with the majority of this population being locating in developing nations.

Show Caption Pesticides can enter the human body through inhalation, ingestion, or by dermal penetration through the skin. Those who work with agricultural pesticides are the most at risk if they are not properly dressed or if there are broken and leaking equipment. The majority of average citizens who are effected by the pesticides intake the pesticide through consumption of a food that was been contaminated with a pesticide."In 1958, all members of the family of a local chief who is a prominent cocoa farmer at Okebode in southwestern Nigeria were hospitalized after eating a leaf vegetable undergrowth of a cocoa farm that was earlier sprayed by lindane. In 2004, carbofuran pesticide residues found on several batches of noodles manufactured in Nigeria may have resulted in 23 reported cases of vomiting and one death" (Monosson, 1). Pesticides cause headaches, blurred vision, vomiting, abdominal pain, suppress the immune system, lead to blood and liver diseases, depression, asthma, and nerve damage. The issue with these effects is that they may wait appear until a while after being ingested so tracing the symptoms back to the pesticide can prove to be quite difficult. Many of the symptoms can be mistaken for the flu and therefore not properly treated. The inactive ingredients such as chloroform can also cause serious risks to the liver and nervous system. These effects can also be experienced by the animals living around the streams where the pesticides accumulate. The pesticides bioaccumulate within the animals as they are not easily soluble, as that animal is eaten by another animal the pesticide then biomagnifies and obtains an even higher concentration as it moves further up the food chain.

Prevention or Mitigation The easiest way to prevent the spread and abundance of agricultural pesticides is through education. If more farmers, especially in developing countries, knew about the risks of these pesticides, they would be more careful in the way that they use the pesticides and the protection that the sprayers wear. Another way is to adopt the Integrated Pesticide Management program which "emphasizes non chemical and cultural pest control strategies such as removal of diseased plant parts, crop rotation that may disrupt the life cycle of pests, and biological control such as the use of insect predators" (Monosson,1). Particular attention needs to be paid to the developing world as their lower health status makes them more vulnerable to disease and they are usually dependent upon farming as their main source of income and economy. In more developed countries where health and wealth are not such huge issues, consumers can decrease their risk of consuming agricultural pesticides by selecting products that are deemed organic which means that no pesticides were used during the production of those foods. Non government organizations are providing the best prevention strategies at the moment. There are groups that provide educational sessions, telephone hotlines, and safety classes. The UN Food and Agriculture Organization and the convention on Persistent Organic Pollutants are making global efforts to decrease the presence and abundance of the harmful pesticides.Many states within the United States have installed a Clean Sweep program which provides for proper cleanup and disposal of these pesticides. To see which states are included in the program click here EPA Clean Sweep.

Soil Conservation Soil conservation is a combination of all methods of management and land use that safeguard the soil against depletion or deterioration by natural or man-induced factors. It most often attempts to ensure that SOIL does not erode and wash into streams and lakes or blow away in the wind, but it also involves the protection of the soil from damage by machinery (eg, compaction) or by detrimental changes to its chemistry (eg, acidification or salinization). But soil also has a much broader, global role. Soil acts as a filter, cleaning air and water. It exchanges gases with the atmosphere and thus influences the global CLIMATE. Soil receives organic wastes and recycles their nutrients back to plants; it also holds and breaks down some toxic wastes. Because soil plays such a key role in world health, economics and environmental stability, we must conserve it and use it in a sustainable manner. Effect of Land Use and Management Causes of Declining Soil Quality The inherent or natural quality of a soil is determined by the geological materials and soil-forming processes (such as chemical and physical WEATHERING) that combine to produce it. The characteristics of a natural soil can be changed by human activities, including land use and farming practices. In agriculture and forestry, decline of inherent soil quality can occur because of EROSION, loss of soil organic matter, compaction, desertification and other degrading processes. Soil Conservation Practices Soil conservation practices are commonly used in forestry during harvesting and replanting operations. The quality of agricultural soils can also be maintained (conserved) or even improved by using soil conservation practices. Examples of these practices include adding organic material (eg, manure) and inorganic amendments (eg, LIMESTONE), using conservation tillage (reduced tillage or no-tillage systems), reducing the amount and frequency of use of summer fallow, rotating CROPS and growing LEGUMES (eg, clover). The type of farming activity that takes place on an area of land, be it pasture or cultivation of forage or fibre crops, cereals, oilseeds, berry fruits or vegetables, depends on the type of soil, the climate and whether crops are grown under natural rainfall or IRRIGATION. The more any land use disturbs the land's natural ecology, the greater its effect on soil quality.

Look for more information in other resources in case you need it to understand better. On pasture lands, agricultural management practices include restricting the density of animal stocking, using rotational grazing (resting fields after they have been grazed), controlling weeds, and protecting vegetation and banks along water courses. On cultivated lands, soil management practices include crop selection and rotation, choice of tillage methods (leaving crop residues on the surface or plowing them into the soil), controlling the traffic patterns of tractors and machinery, determining rates of FERTILIZERS and other soil amendments to apply, controlling pests and managing water. Crops that provide high-density and year-round ground cover offer greater protection against soil erosion than row-cropping or cropping systems that include extensive use of cultivated fallow. Minimizing the amount of tillage used for weed control or seedbed preparation reduces the breakdown of soil structure (the arrangement of soil particles into granules or clods), and keeps more plant residues on the soil surface compared to more intensive tillage. This helps maintain soil tilth and control soil erosion. Reducing the rate of oxidation of soil organic matter can contribute to increasing the amount of carbon stored in the soil, which is an important factor in reducing the greenhouse gas effect (the accumulation of carbon dioxide and other gases in the atmosphere). Soil management that returns plant nutrients to the soil at the rate of their removal by crops will help maintain soil fertility. Reduced use of PESTICIDES on erosion-prone soils, or use of pesticides accompanied by effective soil conservation measures, reduces the risk of contaminated sediments getting into surface water. Acceptance of Soil Conservation Practices Soil conservation practices have been increasingly adopted on Canadian farms since the 1980s. In 1996, the area managed by no-till practices accounted for approximately 16% of cropland. This area has since increased to approximately 56%. Soil-conserving tillage practices (conservation tillage and no-till combined) now represent about 80% of Canadian cropland. Nationally, the amount of farmland under summer fallow, which had decreased by two-thirds between 1981 and 2006, has further decreased by 40.5%. Agriculture and Agri-Food Canada (AAFC) has developed a series of Agri-Environmental Indicators for use in tracking the trends relating to soil conservation and environmental sustainability. AAFC reported on the trends in these indicators for the period 1981 to 2006 (the most recent period for which statistical information is available) in Environmental Sustainability of Canadian Agriculture: Agri-Environmental Indicator Report Series - Report #3 in 2010. Trends in all the soil-quality indicators showed considerable improvement between 1981 and 2006. The majority of the cultivated land in Canada is in the very low risk class for erosion. Canadian cropland has gone from a net source to a net sink of CO 2 gas Yunuen Pérez Centeno MA Student name:______________________________ UNIVERSIDAD TECNOLÓGICA DE TECAMACHALCO Ingeniería en Agricultura Sustentable y Protegida Date: ENGLISH I Class: 7B Assignment Considerations: 1.

Moreover, the share of land at risk of salinization has also decreased over this period. This general improvement does not apply to all soils, however, and there remain significant areas of farmland at risk of degradation. Nevertheless, the AAFC provided evidence that the health of our agricultural soils can indeed be maintained and even improved with the right care. From this data, three general trends have emerged. First, conservation-oriented farming practices are required to maintain soil health, particularly in areas of intensive cropping and where soils are marginal for agriculture. Secondly, soil health can be maintained or is improved in regions where land use and management practices have been tailored to address soil resource and climatic influences that may combine to produce local problems of soil degradation. Finally, declines in soil health occur rapidly, often most dramatically in the first 10 years following conversion of undisturbed land to agriculture, but improvements to soil quality take place slowly and at greater cost than maintaining a good soil in top condition.
