| 摘 要： | 于2013年对舟山群岛潮间带表层沉积物中重金属（cu、Pb、cd、zn、cr、Hg、As）和多氯联苯（PcBs）含量进行了测定，采用单因数污染指数法和Hakanson生态风险指数法评价潮间带沉积物污染状况及其潜在生态风险。结果表明，cu、Pb、Cd、Zn、Cr、Hg、As和PCBs的平均含量分别为30．8、27．5、0．183、91．6、41．4、0．064、8．24mg/kg和0．24μg／kg。评价结果显示：研究区域处于中等污染水平和中等潜在生态风险水平，各要素污染程度为Hg〉Cd〉Cu〉Zn〉Pb〉As〉Cr〉PCBs，潜在生态风险程度排序为Hg〉Cd〉As〉Cu〉Pb〉Zn〉Cr〉PCBs，Hg、Cd为首要潜在生态风险因子。

| Abstract: | The contents of heavy metals and PCBs in surface sediments in intertidal zone of Zhoushan Is- lands were analyzed in 2013. The pollution status and potential ecological risk were evaluated with single fac- tor index and Hakanson ecological risk index. The results showed that the average concentrations of Cu, Pb, Cd, Zn, Cr, Hg, As and PCBs were as follows： 30.8, 27.5, 0.183, 91.6, 41.4, 0.064, 8.24 mg/kg and 0.24 μg/kg. The pollution status belonged to moderate pollution degree mainly, with the order of Hg〉Cd〉Cu〉Zn〉Pb〉As〉 Cr〉PCBs. The potential ecological risk degree belonged to moderate level on the whole with the order of Hg〉 Cd〉As〉Cu〉Pb〉Zn〉Cr〉PCBs. The main pollution factors were Hg and Cd. |
