Basic processes driving the environmental fate of pesticides in soil

Pesticides are common contaminants of natural water resources. After its introduction in soil pesticides dissipation is controlled by basic processes including degradation, biotic or abiotic, adsorption, volatilization and leaching. Currently, pesticide risk assessment is based on the application of mathematical models whose estimation are strongly dependent on the selection of  the correct input parameters describing basic processes. Therefore, there is a need for high quality degradation and adsorption data which will be used as inputs for the estimation of environmental exposure. Our group has long standing experience on studying the contribution of different process on the environmental fate of pesticides. This determined through classic aerobic soil degradation studies, soil adsorption/desorption studies, leaching column studies and radiorespirometry mineralization studies in soil.
