摘要

The residues of 19 EPA-organochlorine pollutants were analyzed in sediments collected from 49 different locations along the semi-closed areas of Alexandria, Egypt. The pollutants studied were 7 individual polychlorinatedbiphenyl (PCB) congeners, α,β,γ-hexachlorocyclohexane (HCHs), cyclodienes (aldrin, endrin, dieldrin) and dichlorodiphenyltrichloroethanes (DDTs) (o,p-DDE, p,p-DDE, o,p-DDD, p,p-DDD, o,p-DDT, p,p-DDT). The concentration of total DDTs ranged between ND and 123.76 ng.g-1 (dry wt) whereas the concentration of PCBs, HCHs and cyclodienes ranged from ND to 192.24 ng.g-1;ND to 20.78 ng.g-1 and ND to 8.04 ng.g-1 dry wt, respectively. The average total organic carbon (TOC) percent was varied from 0.04 to 7.65%.
