Endosulfan Sulfate Mobility in Soil Columns and Pesticide Pollution of Groundwater in Northwest Morocco
Abstract:Groundwater pollution from agricultural practices is a serious environmental and health problem. In this work, stir bar sorptive extraction (SBSE) and gas chromatography (GC) with mass spectrometry (MS) detection were used to determine phytosanitary products in groundwater samples from the Loukkos perimeter in Northwest Morocco. Some pesticides—in particular, endosulfan and its metabolites—were found in water destined for human consumption. Analyses of soil samples were also carried out, and the results showed endosulfan sulfate and endosulfan ether in abundance. Endosulfan sulfate leaching was also performed in undisturbed soil columns to obtain more information on the vertical migration of pesticides used in the perimeter. The kinetic study showed a high recovery rate (73%) after 10 days of experimental work.
