| 摘 要： | 测定了汀江某河段9个采样点表层沉积物重金属元素（As、Cr、Cd、Cu、Pb、Zn）的含量,并采用富集系数法、地累积指数法和潜在生态风险指数法对表层沉积物中重金属污染情况进行评价。研究结果表明,该河段表层沉积物受重金属污染已相当严重,其中以Cd污染最为严重,Cu、As次之,Cr、Pb、Zn污染较轻。总体上属于生态危害性很强的重污染水平。

| Abstract: | This paper determined the elements of heavy metals （As, Cr, Cd, Cu, Pb, Zn） among 9 sampling sites in surface sediments from a reach of Tingjiang River, and the pollution was assessed by using the methods of accumulation coefficients, index of geo-accumulation, and potential ecological risk indices. The results showed that the pollution degree of surface sediments is rather serious, with strong ecological harm; the pollution of Cd is the most serious among all the heavy metals in surface sediments, followed by Cu, As and Cr, Pb, Zn. |
