Research Abstract

Biomagnification profiles of PCBs and PBDEs through shallow water ecosystems around Japan were analyzed by congener level using nitrogen stable isotope ratios as guides to trophic structure. About 130 to 155 PCB congeners were detected in half of the biological samples collected from shallow water ecosystems of western Japan. For these PCB congeners, degree of biomagnification on a wet weight basis exceeded that on a lipid weight basis. For each PCB congener level, the degree of biomagnification increased with increasing chlorination substitution up to about 6 chlorine numbers; the degree of biomagnifications did not increase thereafter at higher chlorination substitution numbers. The degree of PBDE congener biomagnification was lower than that of PCB congener with same degree of lipophilicity.
