| Abstract: | Concentrations and chiral signatures of hexachlorocyclohexanes(HCHs) and dichlorodiphenyltrichloroethanes(DDTs) in surface sediments from Jiaojiang Estuary in Taizhou were determined.Results indicated that concentrations of HCHs,DDTs and OCPs in sediments ranged from 0.65~1.72 ng/g,1.30~34.31 ng/g and 1.95~35.07 ng/g respectively,with DDTs in sediments higher than HCHs.Distribution characteristics of components showed that HCHs and DDTs were not only related to early residues in environment,but also related... |
