서해중부 연안에 서식하는 패류 체내의 PCBs와 PAHs 축적특성

Abstract

The composition of PAHs and organochlirines in Manila clams collected on the mid-western coast of Korea was studied. MW202 and MW228 appeared as important individual PAH compounds implying that pyrolytic PAH is an important source for PAHs in the study area. Tetra-chloro CB appeared to be the most important congener of PCBs found in intertidal sediments. Tetra-chloro CB and Penta-chloro CB appeared to be important congener of PCBs found in Manila clams. THe reason of the different accumulation pattern of organic pollutants in Manila clams and oyaters are discussed.
