中文摘要	本文采取现场研究和实验室研究相结合的方式,研究了16种典型的多环芳烃在海水养殖鱼类鲈鱼肝脏的蓄积作用,以及在清洁海水暂养下的去除作用。结果表明:(1)鲈鱼肝脏对水体中16种多环芳烃的富集系数大于500,并随着多环芳烃分子量的增大而增大,对于海洋食品的安全构成一定的威胁。(2)在鲈鱼肝脏中,高分子量多环芳烃比低分子量多环芳烃易于清除。(3)采用一级指数衰减方程描述了多环芳烃在鲈鱼肝脏的代谢过程,对于高分子量的多环芳烃的半减期为1.7～2.5d,而低分子量多环芳烃的半减期为3.4～24d。通过清洁海水暂养,能有效地减少多环芳烃污染对水产品的食品安全风险。; Food safety is more and more important to human being, while Lateolabrax japonicus is an important mariculture fish in southeastern seas of China. In the present study, we determined concentrations of 16 EPA priority PAH in seawater, liver of Lateolabrax japonicus using GC/MS techniques. The results showed that: (1) Bioconcentration factor (BCF) values in the liver are more than 500, increasing with the increase of PAHs’ molecular weights; so, PAH pollution is a threat to seafood security. (2) PAH with higher molecular weight is more easily depurated than the ones with lower molecular weight; (3)Dynamic equation is given to describe the depuration course. t1/2 of the higher molecular weight PAH component are 1.7 to 2.5 days, and t1/2 of the lower molecular weight PAH component are 3.4 to 24 days. It shows that it is effective to keep fish in clean seawater for seafood security.; 【作者单位】集美大学生物工程学院；厦门大学近海海洋环境国家重点实验室；厦门大学近海海洋环境国家重点实验室福建厦门361021厦门大学近海海洋环境国家重点实验室；福建厦门361005；【作者英文名】LIN Jian-qing1,2,WANG Xin-hong2,HONG Hua-sheng2 (1.School of Bioengineering, Jimei University, Xiamen 361021, China; 2.State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China)
