Risk Assessment and Mitigation in Development and Registration of Crop Protection Products

摘要

@@ One goal of both the product development and the registration processes should be to prevent uses of specific crop protection products under conditions with unacceptable environmental or human health impacts. Because of the benefits associated with the use of crop protection products for agriculture, an equally important goal should be to allow uses under conditions without adverse impact on human health or the environment. To achieve both goals, risk assessment has been used by registrants and regulatory agencies to determine the likelihood of potential adverse effects by combining results of laboratory studies, field research and monitoring studies, and exposure modeling. When a product has the potential for unacceptable impacts for some potential uses, the registration decisions based on calculated risks should still allow the use of the product, but incorporate mitigation measures to prevent adverse impacts. Examples of such mitigation measures include preventing the uses under certain environmental conditions (soil textures, organic matter, and depth to ground water) and the use of drift reduction technologies, no spray zones, and vegetative buffer strips.
