Abstract
The body burdens of environmentally persistent chlorinated insecticides such as DDT and its metabolites and HCH (BHC) isomers in 14 species of marine fishes collected from Tamil Nadu (Madras, Cuddalore, Nagapattinam and Tuticorin) and Pondicherry coasts of Bay of Bengal in South India were reported. The total HCH was more dominant than total DDT. Moreover α-HCH and p, p′-DDT were greater among HCHs and DDTs respectively. Higher concentrations of both the compounds were detected in the tissues of rays ( Dasyatis sp.), Lates calcarifer, Scomberomorus guttatus and Nemipterus japonicus.
