Pesticide residues in bovine milk from a predominantly agricultural state of Haryana, India.
One hundred forty seven samples of bovine milk were collected from 14 districts of Haryana, India during December 1998-February 1999 and analysed for the presence of organochlorine pesticide (OCPs) residues. summation operator HCH, summation operator DDT, summation operator endosulfan and aldrin were detected in 100%, 97%, 43% and 12% samples and with mean values of 0.0292, 0.0367, 0.0022 and 0.0036 microg/ml, respectively. Eight percent samples exceeded the maximum residue limit (MRL) of 0.10 mg/kg as recommended by WHO for summation operator HCH, 4% samples of 0.05 mg/kg for alpha-HCH, 5% samples of 0.01 mg/kg for gamma-HCH, 26% samples of 0.02 mg/kg for beta-HCH as recommended by PFAA and 24% samples of 0.05 mg/kg as recommended by FAO for summation operator DDT. Concentrations of beta-HCH and p,p'-DDE were more as compared to other isomers and metabolites of HCH and DDT.
