| 摘 要： | 以漓江桂袜市区段表层沉积物为研究对象，测定了表层沉积物中CA、As、Cu、Zn、Pb、Cr、Ni、Fe、Mn等14种元素的含量，采用潜在生态风险指数（RI）、相关分析和聚类分析等方法，研究了沉积物中重金属的污染水平、富集规律和可能来源。结果表明Cd污染最为严重，其它元素为轻微生态污染，污染程度为：Cd〉As〉Cu〉Pb...

| Abstract: | The concentrations of Cd,As,Cu,Zn,Pb,Cr,Ni,Fe and Mn were analyzed in surface sediment samples from the Lijiang River,Guilin City.By using a potential ecological risk index,correlation analysis and cluster analysis,the pollution and accumulation of heavy metals in surface sediments were studied.The results showed that Cd is one of the major pollutants,other elements are minor ones.The pollutants affected by potential ecological risk coefficient are,in decreasing order,Cd,As,Cu,Pb,Ni,Zn and Cr.A factor analy... |
