摘　　要：根据 1997年 月大港湾海域环境调查资料,着重分析了大港湾海水、表层沉积物及水产生物体 7内重金属的含量及分布。结果表明:大港湾海水中 Cu, Pb, Cd, Zn 的含量均低于渔业水质标准。大港湾湾顶水域,海水和表层沉积物中 Cu, Pb, Cd, Zn的含量明显高于湾口水域;湾南部水域高于北部水域。文中还根据《海洋沉积物质量》、《无公害食品》、《食品中锌限量卫生标准》、《海洋生物质量》标准对表层沉积物和 种水产生物的重金属污染程度进行评价,结果大港湾的水产生物体内的重金属含量均未超 6标,但沉积物中的 Cd 含量已超标。Based on the data of environmental survey obtained from the Dagang Bay, Fujian Province in July 1997, the concentrations and distributions of heavy metals in sea water, surface sediments and aquatic organisms are analyzed. The results may be summarized as follows: The contents of Cu, Pb, Cd, Zn in sea water at the Dagang Bay are all below the Fisheries Water Quality Standard. The contents of Cu, Pb, Cd, Zn in sea water and surface sediments from the head water of Dagang Bay are much higher than those in the estuary water of the bay. Those in the south waters are much higher than those in the north waters. In addition, according to the values of Standard for Marine Sediments Quality and Public-Disaster-Free Foods and Marine Biological Quality and Tolerance Limit of Zinc in Foods of China, the pollution level of the six species of aquatic organisms and surface sediments by heavy metals have been assessed. The results show that the concentrations of heavy metals in the aquatic organisms at the Dagang Bay are all below the standards, except the contents of Cd in the sediments.
