Eco-Toxicological Risk Assessment of HCH, DDT and their Possible Sources by Isomeric Ratio Distribution in Sediments from Sundarban Mangrove Ecosystem in Bay of Bengal, India
Abstract
Persistent organochlorine pesticides (OCPs) like hexachlorocyclohexane (HCH), and dichlorodiphenyltrichloroethane (DDT), their isomeric ratios and ecotoxicological risks assessment was studied in sediments from Sundarbans in India. These levels significantly moved up to 10 km offshore and decline offshore (22.5 km). Isomeric ratios of DDT and HCH reflects the recent input of HCH and DDT.
