Abstract: In this study, residues, possible sources and ecological risk of 22 polychlorinated biphenyls (PCBs) in five mollusks from Zhoushan Fishing Ground (ZFG) were studied. The total concentration of PCBs in the collected samples ranged from 18.0 ng/g dry weight (dw) to 95.9 ng/g dw, with average of 51.9 ng/g dw. Compared with mollusks from other sea areas, the levels of PCBs in ZFG were at the median worldwide. The results of composition profiles show that penta- and di-PCBs are the most abundant. The health risk of PCBs calculated was far below 1, indicating low risk to human health.

Key words: Zhoushan Fishing Ground, mollusk, polychlorinated biphenyls, health risk
