Analysis of Pesticide Residues in Ground and Surface Water of Bijapur District, Karnataka.

Water samples were analysed for pesticide residues employing multi residue analysis by gas chromatography mass spectrometric method (GC-MS) method and GC-MS on the selected ion mode. The column used was SPB-608 and helium was used as the carrier gas. The HP gas chromatograph equipped with nitrogen phosphorous detector with mega bore column of polysiloxane was used. Among the organochlorines, HCH and DDT were not detected in almost all samples. All the water samples showed the presence of residues with one or other group of residues. Residues of the pesticides exceeded the permissible values in some samples. The aim of this study was to establish a systematic analytical method for the rapid and sensitive probe in monitoring of pesticide residues in water samples of Bijapur ground and surface water.
