| 摘 要： | 对广州市番禺区榄核河沉积物中5种典型重金属(Cu、Zn、Pb、Ni、Cr)的含量水平进行分析,并在此基础上评价其潜在生态风险。结果表明,榄核河沉积物中各重金属元素的含量均远远高于广州市土壤背景值;各重金属元素生态风险由大到小顺序为CuNiPbZnCr,总体表现为强或很强,表明研究区域沉积物呈现多种金属复合污染特征,生态危害程度相对较高。

| Abstract: | The contents of heavy metal Cu, Zn, Pb, Ni and Cr in sediment of Lanhe River were measured, and the potential ecological risk of these heavy metals were analyzed. The results indicated that the contents of five heavy metals were significantly higher than the background values of soil in Guangzhou. The heavy metals in Lanhe River showed strong or very strong eco]ogical risk, and the potential ecological risk of heavy metal decreased as followed Cd 〉 Cu 〉 Cr 〉 Zn 〉 Pb. The pollution characteristic of research region showed joint contamination by more than one element and relatively higher ecological hazards. |
