摘  要：
为了解北江水产品中铅含量情况,在北江清远地区河段设英德沙口、英德连江口、清新县飞来峡大坝和清城石角镇4个监测河段,对渔获样品进行铅含量检测。结果表明不同监测点铅平均含量依次为英德沙口>英德连江口>清新县飞来峡大坝>清城石角镇;三类水产品中铅平均含量以贝类最高,达4.21 mg/kg;按鱼类不同食性来分析,肉食性鱼类铅残留指数最高,为1.42;按鱼类不同生活水层来分析中下层鱼类铅残留指数最高,为1.73。

摘  要：
In order to inspect concentration of lead in tissues of fishes,crustaceans and bivalve mollusks from Beijiang river,we collected the aquatic products sampled from four monitored sites,Yingde Shakou,Yingde Lianjiangkou,Feilaixia dam of Qingxin and Qingcheng Shijiao in Qing-yuan reach of Beijiang River.The results showed that the sequence of average content of lead in the aquatic products was Yingde Shakou>Yingde Lianjiangkou>Feilaixia dam of Qingxin>Qingcheng Shijiao in Qingyuan.The average content of lead in bivalve mollusks was 4.21 mg/kg,which was the highest among the three kinds of aquatic products.The lead content of carnivorous fish and the middle and lower layer fish was the highest,and their residual index was 1.42 and 1.73,respectively.
