Organochlorine pesticides in irrigation water of Jaipur City (India).
The present study was carried out to evaluate the pesticide content in irrigation waters used in agricultural fields located in agriculture intensive areas adjoining the Jaipur city (India). Pesticide residues were monitored in irrigation water samples collected from open wells/tube wells located in these areas. Most of the water samples were found to be contaminated. Pesticides--HCH, Endosulphan, Dieldrin--concentrations of tube well/open well irrigation waters in monsoon season ranged from 2.25-12.23 ppb, 3.32-13.18 ppb and 0.081-0.470 ppb respectively. In post-monsoon period the concentrations were in the range of 3.35-15.46ppb for HCH, 4.21-16.08 ppb for Endosulphan and 0.154-1.01 ppb for Dieldrin.
