Abstract
In the present study gas chromatographic analysis of pesticide residues in bovine milk n = 312 from Punjab India showed chlorpyrifos DDT and γHCH as the predominant contaminants In addition the presence of βendosulfan endosulfan suphate cypermethrin cyhalothrin fenvalerate deltamethrin malathion profenofos and ethion was reported in milk samples In this study it was observed that 12 milk samples exceeded the maximum residue limits MRLs for γHCH lindane 18 for DDT and chlorpyrifos and 1 sample each for endosulfan cypermethrin and profenophos In India DDT is still permitted for a malaria control program which may be the plausible reason for its occurrence in milk samples The spatial variation for presence of pesticide residues in milk indicated greater levels in cottongrowing areas of Punjab At current levels of pesticide residues in bovine milk the human health risk assessment in terms of noncancer and cancer hazard was calculated based on both lowerbound LB mean residue levels and upperbound UP 95th percentile level limits It was noticed that cancer and noncancer risk were within United States Environmental Protection Agency prescribed limits for both adults and children at the LB but children were being exposed to greater risk for DDT and HCH at the 95thpercentile UB level
