Evaluation of human exposure to the persistent insecticides DDT and HCH in Ahmedabad, India.
Concentrations of two organochlorine insecticides, DDT and HCH, in 21 human adipose tissue samples (from cadavers) and 20 venous blood samples collected in Ahmedabad, India were determined. None of the cases had any history of occupational exposure to organochlorine insecticides. Residue concentrations of DDT and HCH in these samples indicated considerable exposure of the general population to these chemicals. Samples from males had comparatively higher concentrations of these insecticide residues than females. The mean residue concentrations of total DDT and HCH in the blood serum of males was 213.83 and 70.051 ppb, respectively, whereas females had DDT and HCH concentrations of 177.38 and 65.44 ppb, respectively. Total DDT and HCH in adipose tissue was 3.967 and 4.054 ppm in males, and 3.538 and 3.144 ppm in females, respectively. Residue concentrations reported here are lower than those reported earlier.
