Pesticides
Description
A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests. Pesticides include herbicides for destroying weeds and other unwanted vegetation, insecticides for controlling a wide variety of insects, fungicides used to prevent the growth of molds and mildew, disinfectants for preventing the spread of bacteria, and compounds used to control mice and rats. Because of the widespread use of agricultural chemicals in food production, people are exposed to low levels of pesticide residues through their diets. Scientists do not yet have a clear understanding of the health effects of these pesticide residues. Results from the Agricultural Health Study, an ongoing study of pesticide exposures in farm families, show that farmers who used agricultural insecticides experienced an increase in headaches, fatigue, insomnia, dizziness, hand tremors, and other neurological symptoms. Evidence suggests that children are particularly susceptible to adverse effects from exposure to pesticides, including neurodevelopmental effects. People may also be exposed to pesticides used in a variety of settings including homes, schools, hospitals, and workplaces.

General Information
- Pesticide Action Network North America - PAN seeks to reduce the use of pesticides through more economically viable alternatives. Publishes reports on pesticide use, health effects, occupational safety, etc. Website also offers a Pesticide Database that allows you to search by chemical or product.
- Pesticide Exposure - The National Library of Medicine's (NLM) Enviro-health links website provides an excellent set of resources that address the relationship between pesticides and human health. The page provides links to selected websites on pesticide exposure, as well as on the treatment and prevention of pesticide poisoning.
