COMPARISON OF THE RISK ASSESSMENT PROCESS FOR PESTICIDES AND BIOPESTICIDES
Citation:
Burns, L A. COMPARISON OF THE RISK ASSESSMENT PROCESS FOR PESTICIDES AND BIOPESTICIDES. Presented at 226th American Chemical Society National Meeting, New York, NY, September 7-11, 2003.
Impact/Purpose:
Extend existing model technologies to accommodate the full range of transport, fate and food chain contamination pathways, and their biogeographical variants, present in agricultural landscapes and watersheds. Assemble the range of datasets needed to execute risk assessments with appropriate geographic specificity in support of pesticide safety evaluations. Develop software integration technologies, user interfaces, and reporting capabilities for direct application to the EPA risk assessment paradigm in a statistical and probabilistic decision framework.
Description:
In the risk assessment process for pesticides, a number of variables are used, including the results obtained from the studies that support registration. Some of these variables are physical and chemical properties of the organisms (crops, growing cycles) and their environments (soils, adjacent surface and ground waters) to be protected. Methods of application, environmental conditions, transport from the site of application, and transformation (degradation) of the applied materials are also considered in assessing populations). Although these assessments are made with data and other available information for conventional pesticides, the comparable information for biopesticides is more sparse. The risk assessment processes for these protective agents are compared.
