Dietary Exposure Potential Model

Dietary Exposure Potential Model (DEPM) Model and database system for deterministic dietary exposure Exposure from pesticides in diet combines food consumption and residue data USEPA (2003a)... 

USEPA (2003a) Dietary exposure potential model A model using extant food databases to estimate dietary exposure to chemical residues. Latest version 5.0 released April 2003. Washington, DC, United States Environmental Protection Agency (http // www.epa.gov/nerlcwww/depm.htm). 

U.S. EPA s Office of Pesticide Programs has used DEEM in its exposure and risk assessments. The Dietary Exposure Potential Model (DEPM) is another ingestion model that facihtates the correlation of food consumption data and chemical residue data (Cherrie et al. 2006 Tomerhn et al. 1997 US EPA 2003a).

Dietary exposure to pesticides (or to xenobiotics in general) is determined by calculating the product of the amount of chemical in or on the food and the total quantity of food consumed. The quantity of chemical potentially consumed in foods can be estimated from data obtained from residue field trials, metabolism studies, and/or monitoring data. Information from these sources is then analyzed with one of several available models containing food consumption factors from surveys conducted by the United States Department of Agriculture (USDA). For calculation of...
