Residues and Bioaccumulation Patterns of Polycycleic Aromatic Hydrocarbons in Various Marine Organisms in Relation with Their Exposure Pathway

Abstract

We collected sediments from the Nakdong River estuary and Ulsan Bay. The levels of polychlorinated biphenyls( PCBs) and organochlorine pesticides(OCPs) were determined to investigate the availability of SRM and its homogeneity. The 8 congeners of PCBs and chlordane, p,p'-dichlorodiphenyldichloroethane(DDD), p,p’- dichlorodiphenyldichloroethylene(DDE), p,p'-dichlorodiphenyltrichloroethane(DDT), dieldrin, hexachlorobenzene (HCB), and oxychlordane were determined by a capillary column gas chromatography/electron capture detector system. The environmental levels of these species and their relative standard deviations are discussed
