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。
測定瞭汀江某河段9箇採樣點錶層沉積物重金屬元素（As、Cr、Cd、Cu、Pb、Zn）的含量，併採用富集繫數法、地纍積指數法和潛在生態風險指數法對錶層沉積物中重金屬汙染情況進行評價。研究結果錶明，該河段錶層沉積物受重金屬汙染已相噹嚴重，其中以Cd汙染最為嚴重，Cu、As次之，Cr、Pb、Zn汙染較輕。總體上屬于生態危害性很彊的重汙染水平。

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.
