福安白马港海水、沉积物及水产生物体内重金属含量分布

根据2005年12月白马港海域环境调查资料,着重分析了白马港海水、表层沉积物和两种水产生物体内Cu、Pb、Cd、Zn的含量及分布.结果表明:海水中Cu、Pb、Cd和Zn的含量均低于第二类<海水水质标准>,水质良好;表层沉积物除个别站位Zn含量略高于标准外,其余均低于<海洋沉积物质量>中的第一类评价标准;两种水产生物体内重金属的含量除菲律宾蛤仔体内Cd含量超标外,其余均符合<无公害水产品安全要求>和<食品中锌限量卫生标准>.

Distribution of Heavy Metals in Seawater, Surface Sediments and Aquatic Organisms from Baima Bay

Based on the data of environmental survey obtained from Baima Bay in Dec.2005,the distributions of heavy metals in seawater,surface sediments and aquatic organisms were analyzed.The results showed that the contents of Cu,Pb,Cd,Zn of seawater were below the second degree of Sea Water Quality Standard.And,except Zn content of sediment in B4 station,con- tents of four metals were all less than the values of the first degree of Standard for Marine Sediments Quality.Last,the heavy met- als contents in two aquatic organisms also answered for Safety requirements of Not-public disaster aquatic product and Tolerance Limit of Zinc in Foods of China except Cd content in Ruditapes philippinarum.
