서해중부 조간대 바지락 체내의 PAH와 유기염소계화합물 조성

Abstract

The composition of PAHs and organochlorines in Manila clams collected on the mid-western coast of Korea was studied. Concentrations of tPAHs in sediment were in the range 86.0∼244.1ng/g dw. 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 the intertidal sediments. Penta-chloro CB accounted for 29.4∼58.1% of total PCBs found in Manila clams. Accumulation of PCB-28, PCB-44 decreased with increasing shell length of Manila clams. The reason for the different accumulation pattern of organic pollutants in Manila clams and mussels are discussed.
