| 摘 要： | 采用污染指数法和生态风险指数法对珠江口狮子洋海域表层沉积物中Hg、Cu、Cd、Pb、As等污染要素进行分析和评价。结果表明:该海域的总体污染程度为低污染水平,污染程度由大到小依次为As>Cu>Pb>Hg>Cd;该海域的总体生态风险性为低,生态风险性由高到低依次为Hg>As>Cd>Cu>Pb,Hg为该海域的主要潜在生态风险因子。

| Abstract: | Pollution index method and Hakanson potential ecological risk index method are used to study and analyze the contents of typical pollutants(Hg,Cu,Cd,Pb,As) in surface sediments of Shiziyang in Pearl River estuary.The results show that the overall contamination level and potential ecological risk of the typical pollutions is low in this sea area.The sequence of pollution degree of these metals in surface sediments is As>Cu>Pb>Hg>Cd;the potential ecological risk sequence is Hg>As>Cd>Cu>Pb.Hg is the key factor... |
