| 摘 要： | 研究了2007-2009年浙江省嵊泗赤潮监控区表层沉积物和紫贻贝重金属Hg、As、Cu、Pb和Cd含量。结果表明：嵊泗赤潮监控区表层沉积物质量良好,符合一类沉积物质量标准。Cu和Pb的含量明显高于其它3种重金属元素,其次是As〉Cd〉Hg;污染指数大小排序为Cu〉As,Pb〉Cd〉Hg,沉积物将有可能受到Cu的污染,应引起重视。紫贻贝重金属含量大小为Cu〉Cd〉Pb,As〉Hg,Cu、Pb和Cd含量有升高趋势,Pb和Cd的污染指数较高,紫贻贝已受到Pb和Cd的污染。

| Abstract: | According to the data of heavy metals（Hg,Cd,Pb,As and Cu） in the surface sediments and Mytilus elulis in August from 2007-2009 in red tide monitoring area of Shengsi of Zhejiang province.The results showed that the contents of heavy metals in surface sediment accord with the first class of the sediments of National Standards,but the contents of Cu and Pb were obviously higher than the others.The order of heavy metals pollution index in surface sediment was CuAs,PbCdHg.The surface sediment be probably polluted by Cu.The contents order of heavy metals in M.elulis was CuCdPb,AsHg,the pollution index of Pb and Cu were higher,the M.elulis have been polluted by Pb and Cd. |
