| 摘 要： | 安徽铜陵新桥河的沉积物样中，重金属浓度为Cu〉Zn〉Pb〉Cr，按国家土壤环境二级质量标准评价，Cu、Zn含量已超标。其新桥河的沉积物样中，Cu、Zn的污染参数很高，含量为高风险或极高风险；Pb污染参数较高，含量为一般风险或高风险。同时新桥河的沉积物样中，Cu具有很高的潜在生态风险。

| Abstract: | The concentrations of heavy metals in the sediments of Xinqiao stream were Cu>Zn>Pb>Cr,respectively.Cu and Zn concentrations exceeded the National Soil Environmental Quality Standard for Evaluation II.Cu and Zn pollution parameters of the sediments were high with high-risk or extremely high risk;Pb pollution parameter was at a higher general level with general risk or high risk.Cu concentration in the sediments had a high potential ecological risk. |
