Abstract

Under a multicentre study conducted by the Indian Council of Medical Research, 2205 samples of dairy milk were collected from rural and urban areas of 12 states representing di� erent geographical regions of India. These samples were analysed for residues of DDT and di� erent isomers of HCH by gas± liquid chromatography. Analytical quality assurance between various participating laboratories was ensured through analysis of check samples. The residues of DDT and HCH were detected in more than 80% of samples analysed. Concentrations of DDT residues, ¬-HCH, ­ -HCH, ®-HCH and ¯-HCH exceeded their maximum residue limits prescribed by the Ministry of Health and Family Welfare of the Indian Government in 37, 21, 42, 28 and 4% of the samples, respectively. Median values of DDT and HCH found in dairy milk in India were more than the corresponding values reported from most other countries. The results showed signi® cant variations in the incidence as well as level of these contaminants in dairy milk from di� erent regions of the country.
