Pesticide Fate Database

This page provides a description and a link to a "Pesticide Fate Database" database that provides information needed when modeling exposure levels or performing exposure assessment.

Short description

EPA's Office of Pesticide Programs (OPP) collects and reviews a wide range of scientific studies, including chemical fate and transport studies. This information is gathered to Pesticide Fate Database including following information for 188 pesticide active ingredients: physical and chemical properties, chemical fate, transport of pesticide active ingredients registered in the United States, degradates or breakdown products of these registered pesticides and endpoint information such as half lives and soil-water partitioning coefficients. Additional pesticide active ingredients and degradates will be added to the fate database in the near future.

Long description

n determining whether a pesticide can be approved for use in the United States, EPA's Office of Pesticide Programs (OPP) collects and reviews a wide range of scientific studies, including chemical fate and transport studies. These studies describe what happens to a pesticide in soil, water, and air after it has been applied (how it degrades and where it goes) and include the following:

Product chemistry

Metabolism

Hydrolysis

Photolysis

Field Dissipation

Bioaccumulation

Adsorption/desorption and leaching

Chemical fate and transport studies are designed to help identify which dissipation processes are likely to occur when a pesticide is released into the environment and to characterize the breakdown products that are likely to result from these degradation processes.

Endpoint information (e.g., half-lives) from these studies can now be viewed in OPP's Pesticide Fate Database. The initial version of the database contains 188 pesticide active ingredients. Additional pesticide active ingredients and degradates will be added to the fate database in the near future.

Individuals inside and outside the agency will be able to use this database to model or predict the fate of pesticides in the environment and to develop exposure characterizations that describe the potential exposure of plants, animals, and water resources to pesticide residues.
