摘要(Abstract)：

2011年1月-2012年5月间采集了辽东半岛海域11种鱼类和2种贝类样品,分析了其可食部位中22种有机氯农药的残留量,评估了其中DDTs和HCHs的残留对人体健康的风险。在所调查样品中HCB、HCHs和DDTs是主要的污染物,样品中OCPs残留量为57.12~546.15μg·kg-1。利用污染指数计算法评估,旅顺海域小黄鱼、鳙鱼、中国斗鱼和偏口鱼未受到HCHs的污染,棒花鱼受到HCHs轻度污染,其它鱼种样品均受到重度污染,而对于DDTs,只有鲫鱼未受到污染,其它鱼种样品均受到重度污染。大黄鱼、梭鱼、黑鱼和鳙鱼体内HCHs残留量明显高于国标再残留限值,DDTs残留量符合国标标准。α-HCH、γ-HCH、β-HCH、p,p'-DDE、p,p'-DDD和p,p'-DDT的致癌风险指数范围为0.32×10-6~49.57×10-6,均低于10-4,为可接受的致癌风险;α-HCH、γ-HCH、β-HCH、p,p'-DDE的接触风险指数ERI为0.01×10-3~153.28×10-3,均小于1,为可接受的接触风险,但2012年4月的黑鱼样品上述六种农药的CRI总值高于10-4,存在潜在的致癌风险,因此,建议黑鱼的日均食用量应控制在50 g以下较为安全。
