Extensive research has been directed toward the fate of particular pesticides in specific soils and sediments. Typically, extensive testing for each pesticide-soil or pesticide sediment combination is required to determine the fate of a particular pesticide due to the complexity of soils and sediments. The approach of this research was to conceptually model sediments as a combination of several distinct chemical phases and to develop pesticide adsorption relationships for each phase. Which such relationships, adsorption for the sediment can be predicted from the measured concentration of each phase.
