    摘要:

    为探讨多氯联苯(PCBs)污染物在宁波市售海产品中的组成规律及季节变化特征,按不同季节采集10种宁波居民主要食用海产鱼类,采用气相色谱法检测其中7种指示性多氯联苯残留量,并进行人体健康风险评价。结果表明,PCBs的残留质量分数为 0.06~3.98 ?滋g/kg,其中 PCB-52 和 PCB-153 为主要组分。PCBs含量分布特征为秋季最高,冬季次之,夏季最低。宁波市售海产品中多氯联苯残留量水平在可接受的范围内。食用上层鱼的健康风险CV值小于食用下层鱼,PCBs监测是风险评估需要控制的关键因素。

    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.
