摘要
根据嵊泗赤潮监控区2007年～2009年每年的8月表层沉积物及2007年和2008年的8月紫贻贝重金属的监测结果,对沉积物和紫贻贝质量进行分析评价,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依次为Cu>Cd>As>Pb>Hg,而Pb和Cd的污染指数较高,紫贻贝已受到Pb和Cd的污染。
According to the data of heavy metals（Hg,Cd,Pb,As and Cu） in the surface sediments and Mytilus edulis in Aug.from 2007～2009 and 2007～2008 in red tide monitoring area of Shengsi,the quality of surface sediment and Mytilus edulis were studied.The results showed that the contents of heavy metals in surface sediment accorded 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 Cu〉As,PbCdHg.The surface sediment would be probably polluted by Cu.The contents order of heavy metals in Mytilus edulis was Cu〉Cd〉As〉PbHg,the pollution index of Pb and Cd were higher,the Mytilus edulis had been polluted by Pb and Cd.
