Abstract:

The composition characteristics and seasonal variations of polychlorinated biphenyls （PCBs） in fishes sold in Ningbo market were investigated. Ten kinds of fishes were collected in different seasons and the residual contents of seven kinds of involved PCBs were detected by gas chromatography（GC） to discuss health risk assessment. The concentration range of PCBs was determined as 0.06 to 3.98 ?滋g/kg，and PCB-52 and PCB-118 were main components. The highest content of PCBs showed in autumn，successively followed by winter，spring and summer. The residual levels of PCBs in marine products sold in Ningbo market were in an acceptable level. The uncertainty coefficient of variation on PCBs cancer risk caused by pelagic fish intake was lower than that of lower fish. The key to the health risk assessment was the detection of PCBs.
