The Study of Pesticides Pollution in Drinking Water Based on Ground Water Sources

摘要

ABSTRACT The pesticides concentrations in drinking water were determined at different sampling stations in northern suburbs of Tehran during fall and winter 2008-2009. The level of residual concentration of pesticides was determined by HPLC and GC/MS technique. The results showed that the most widely used compound is imidocloprid and the recorded chromatograms by HPLC and GC/MS for drinking water of each village do not show any pesticides of any kind in the sources of groundwater in this region.
