Since 1982, members of our staff have supported EPA’s Office of Pesticide Programs. As part of this contract, our staff assess environmental and human health impacts on anthropogenic chemicals. The agricultural industry is critical to food and textile production, it is a large contributor to the U.S. economy. Not only does the industry provide food and materials for the U.S., it also provides products that are high-demand exports for other countries. Our dedicated staff help support this important industry by helping to ensure products used by the agricultural industry aren’t adversely impacting humans, animals, and the surrounding environment.

Our work consists of
- Evaluating pesticide residues in food and feed crops as well as livestock
- Evaluating mammalian toxicity data for agricultural and industrial chemicals
- Determining critical end-points, no-observed-adverse-effect levels and lowest-observed-adverse-effect, reference doses or reference concentrations, and cancer values
- Assessing risk and analyzing weight of evidence
- Evaluating chemical toxicity to non-target species
- Determining no-observed-adverse-effect levels and lowest-observed-adverse-effect levels
- Monitoring movement, metabolism, and degradation of chemicals in the environment
- Evaluating regulatory compliance and quality assurance
