Leaching and Degradation of Selected Pesticides in a Sandy Watershed


The investigation emphasises leaching and decompostition of selected pesticides on sandy agricultural soil. The fungicide metabolite ETU was chosen as the major model compound, as its parent compound is used intensively in patatoes. In spite of high mobility, ETU was not deteched in groundwater in concentrations exceeding 0.1 ug/1. Experiments on soil columns showed a microbial decomposition of ETU under both oxic and anoxic conditions.
