我国水产品中铅含量监测及应对国际标准制定的对策

为了解我国水产品中铅污染状况，2002年全国污染物监测网对中国10个省市的13个监测点进行了水产品中铅含量监测，初步的结果显示，我国水产品的铅污染目前不严重，淡水鱼、海水鱼、软体贝类、甲壳类等水产品均符合我国的国家标准，也符合CAC及正在制定标准的建议值。但由于不是专项监测，没有针对我国主要经济鱼种进行监测，所监测的数据可能与实际经济鱼种铅含量有一定差距，建议我国尽快立项进行海鱼铅的专项监测，掌握其污染的本底值，在国际标准的制定过程中争取有利于我国的限量标准。本次监测同时提示，虽然我国水产品铅污染并未超过国家标准，但与10年前的监测结果比较上升了3倍，应引起各级政府的重视。

Surveillance of lead contamination in Chinese aquatic products

In order to know lead contamination in fishes,crustaceans and bivalve mollusks in China,Thirteen monitoring sites from 10 provinces were selected to conduct the surveillance of lead in aquatic foods in 2002.The results showed that lead contamination of fish in our country were not severe.Lead levels in fish,crustaceans and bivalve mollusks met both the national criteria and the levels proposed by CAC.As the main economic fishes were excluded in the monitoring program,the data obtained in this study was a bit different from the actual levels for lead in these fishes.Lead surveillance in aquatic products is strongly recommended so as to get the natural occurrence of this heavy metal,and make our contributions to the establishment of international maximum levels for lead in associated foods as well.It should point out that the lead levels in aquatic products in 2002 was three times higher than that of the past decade,although it did not exceed our national criteria.
