摘要
根据2001年7月厦门筼筜湖的水生生态环境调查资料,着重分析了筼筜湖鱼类、虾类、蟹类体内重金属的含量分布。结果表明:筼筜湖内的蟹类体内Cu,Pb,Cd和Zn的含量明显高于虾类和鱼类。文中还根据我国《食品中铜、铅、镉、锌限量卫生标准》,对15种水产生物体内的重金属污染程度进行评价,结果筼筜湖的鱼类和虾类体内的重金属含量基本未超标,但蟹类体内的Pb,Cd含量已超标。
Based on the data of environmental survey obtained from the Yuandang Lake of Xiamen, Fujian Province in July 2001, the concentrations and distributions of heavy metals in fishes and shrimp and crab are analyzed. The results may be summarized as follows： The contents of Cu, Pb, Cd and Zn in crap from the Yuandang Lake were much higher than those in fishes and shrimp. In addition, according to the values of Standard for Tolerance Limit of Copper Lead Cadmium and Zinc in Foods of the People＇s Republic of China, the pollution level of the fifteen species of aquatic organisms by heavy metals have been assessed. The results show that the concentrations of heavy metals in fishes and shrimp from the Yuandang Lake of Xiamen were below the standards, except the contents of Pb, Cd in vrab.
