چکیده
Organochlorine pesticides, such as HCH (Hexachlorocyclohexane) and DDT (dichloro diphenyl trichloro ethane) and its metabolites were analysed in commercially important fishes, collected from the Dadar fish market (Mumbai) in July 2011. Total DDT concentration varied between 14.88 and 58.30 ng.g-1 in the Lisa parsia and Chirocentrus dorab respectively. The minimum and maximum concentrations of total HCH were 4.96 and 19.12 ng.g-1 in the same two species are Lisa parsia and Chirocentrus dorab respectively. In total HCH, the alpha isomer was recorded at very high level when compared with other isomers. Similarly was the dominant metabolic compound in total DDT in all the fish species. The residual concentration of the pesticides in fishes was well below the tolerance limits prescribed.
