Standard reference materials(SRM) have been used to certify the degree of accuracy for determining various kinds of analytes including environmental organic contaminants. In this study, we collected sediments from the Nakdong River estuary and Ulsan Bay. The levels of polychlorinated biphenyls(PCBs) and organochlorine pesticides 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 using a capillary column gas chromatography/electron capture detector system. The environmental levels of these species md their relative standard deviations are discussed.
