为了评估唐山、秦皇岛近岸海域贝类体中多环芳烃（PAHs）的污染水平及其健康风险，于2010年10月采集了唐山、秦皇岛近岸海域贝类样品。利用气相色谱-质谱（GC-MS）法检测贝类体中PAHs含量，运用美国环保局（USEPA）推荐的健康风险评价方法评价其健康风险程度。结果表明，贝类生物体中PAHs含量范围为17.27~331.96 ng·g-1，平均值为117.19 ng·g-1，4-5环PAHs含量比例较高。苯并[a]芘（BaP）毒性当量浓度为0.25~169.99 ng·g-1。秦皇岛近岸海域贝类产品中PAHs的致癌风险指数为1.09×10-4~2.83×10-4，高于USEPA建议的可接受致癌风险指数（10-4），存在一定致癌风险；唐山近岸海域贝类体内PAHs致癌风险指数均在可接受致癌风险之内。

In order to assess the pollution level and health risk of PAHs in mussels, we collected and analyzed the residual PAHs in the shellfish from 7 sites of the offshore area in Tangshan and Qinhuangdao in 2010. The contents of 16 PAHs in the shellfish were detected by GC-MS. The degree of health risk was analyzed by the health risk evaluation method which was recommended by USEPA. The results showedthe residual levels of PAHs in the shellfish ranged from 17.27~331.96 ng·g-1, and the average value was 117.19 ng·g-1. 4-PAHs and 5-PAHs were more dominant in the shellfish. The BaP equivalent(BaPeq)concentration was 0.25~169.99 ng·g-1. The Cancer Risk Index of PAHs in the shellfish which lived in Qinhuangdao offshore was greater (1.09í10-4~2.83í10-4)than the acceptable Cancer Risk Index suggested by USEPA (10-4). There is a risk of cancer if people eat lots of shellfish caught from Qinhuangdao offshore. The content of PAHs in the shellfish from Tangshan was out of the risk of cancer.
