Surface water contamination by organochlorine pesticides residues in Uzbekistan
2008
Nishonov, B.
Organochlorine pesticides as DDT and HCH (POPs) have been prohibited in Uzbekistan. These pesticides can be preserved in soil for long time and enter from agricultural fields to surface water with drainage, wash-out and snowmelt water.Therefore, monitoring of these pesticides in surface water remains very actual. In this paper the results of pesticides monitoring in surface water in Uzbekistan in 2000-2004 have been analyzed. They show tendency to decrease in surface water contamination by pesticides in Uzbekistan. For the period of observations, small concentrations of HCH isomers were determined in surface water, DDT and its metabolites DDD and DDE were not determined in surface water samples.
