August 16-20, 2009. Technical Abstract: Simulation models are useful for estimating the environmental fate and transport of pesticides. Soil fumigants such as methyl bromide are a special group of pesticides with high vapor pressure values. A main concern with fumigants is the large potential for atmospheric emissions. Because of the large emissions and ozone depleting property with bromine, methyl bromide was phased out for soil fumigation use. As a result, a significant amount of research has been carried out on the efficacy and environmental fate and transport of methyl bromide alternatives. This presentation will review modeling activities related to soil fumigant emissions with a special focus on simulating fumigant emission fluxes. A general overview of fundamental physical and chemical principles for modeling the environmental fate and transport of soil fumigants will be provided. Discussions will be made on future needs in modeling fumigant emissions.
