title: HCH and DDT residues in human and bovine milk at Hardwar, India.
abstract: Concentrations of HCH and DDT in human and bovine milk were determined in two areas under malaria control namely, BHEL, Hardwar with bioenvironmental control strategy and rural and urban areas of Bahadrabad PHC of Hardwar district with residual spraying of insecticides. Mean HCH and DDT residues in human milk in BHEL were 0.027 and 0.021 mg/kg, while from Bahadrabad were 0.089 and 0.149 mg/kg respectively. Similarly, mean HCH and DDT contents in bovine milk from BHEL were 0.019 and 0.008 mg/kg, while 0.058 and 0.029 mg/kg, respectively from Bahadrabad. Statistically significant differences were recorded in HCH and DDT levels in human and bovine milk samples between BHEL and Bahadrabad areas of Hardwar district. The mean levels of HCH and DDT in bovine milk samples did not exceed the maximum residual limit of 0.05 mg/kg from BHEL whereas, 38.5% samples from Bahadrabad area exceeded this limit.
