中文摘要:

      目的 调查太湖水域水产品中羟基多溴联苯醚(OH-PBDEs)的污染情况。方法 首先建立测定水产品中OH-PBDEs的方法, 之后分别测定了太湖流域中17种水产品和3种水生蔬菜中的OH-PBDEs。结果 生活在中下层和泥层的水产品体内的OH-PBDEs含量(ND~3.3839 ng/g(干重))高于中上层的(ND~1.6169 ng/g(干重)); 动物水产体内的OH-PBDEs含量高于植物水产的; 常见的鱼中草鱼、鳊鱼、花鲢和桂鱼体内的OH-PBDEs含量高于其他种类的鱼, 且OH-PBDEs多数集中在内脏的内膜脏层。结论 较系统地调查了太湖流域水产品中OH-PBDEs的污染情况。

      Objective To investigate the contamination of OH-PBDEs in aquatic products of Taihu Lake. Methods A method for the determination of OH-PBDEs in aquatic products was established firstly, and then the concentration of OH-PBDEs in 17 kinds of aquatic products and 3 species of aquatic vegetables in the Taihu lake basin was measured. Results Fish living in the middle and lower layers and mud had higher levels of OH-PBDEs(ND~3.3839 ng/g(dw))than the upper’s(ND~1.6169 ng/g(dw)); there was higher level of OH-PBDEs in fish than plant. The concentration of OH-PBDEs in the grass carp, bream, bighead carp and siniperca chuatsi was higher than the other types of fish, and most OH-PBDEs was contained in the intima of the visceral. Conclusion The contamination of OH-PBDEs in aquatic products of Taihu Lake was surveyed systematically.
