Technical Abstract: Pesticides are widely used for crop production, which benefits public health. However, numerous studies have also shown that agricultural use of pesticides can contribute to both atmospheric and water contamination. Pesticide movement in the soil zone and volatilization to the atmosphere is affected by many interrelated factors such as pesticide application methods, soil and environmental conditions, chemical properties and water management practices. Volatilization leads to increases in the concentration of potentially toxic chemicals and increases the VOC content of the atmosphere. USEPA has recently established a new federal 8-hour ozone standard that requires regulators to develop and submit plans to reduce near surface ozone in non-attainment areas and this may lead to restrictions being placed on pesticide use, or require expensive reformulation of pesticide products. The purpose of this presentation is to provide an overview of some of the regulatory issues facing the use of agricultural VOC (i.e., pesticides) in non-attainment areas and to describe current research efforts to improve the predictive of emissions to the atmosphere. The goal is to develop new methodology that will help to protect the environment and allow the continued use of crop protection chemicals in agriculture.
