| 摘 要： | 研究了内蒙古乌梁素海0~20 cm深处底泥中重金属元素的全量,并利用潜在污染生态危害指数法评价了底泥中的重金属的污染风险。根据国家海洋沉积物质量一类标准、生态危害临界值和国家土壤质量一级标准,乌梁素海底泥中重金属的复合污染较严重,污染重金属主要为Cu、Cd、Ni、Zn。底泥中Pb、Cd、As、Cu、Cr、Hg、Zn之间相关性明显,说明湖泊底泥中这些重金属的污染来源相同。重金属生态风险评价结果表明:乌梁素海大部分地区属重金属轻度污染区,仅3个排干渠入口附近为极度污染区,其余地区为重度污染区。 |

| Abstract: | The total contents of heavey metal elements in the bed mud from 0 to 20 cm were investigated in the Wuliangsu lake,and the risk of heavy metal pollution was evaluated using ecology risk harm index method.According to the state standard of ocean sediment quality(first level),threshold effective level and state standard of soil quality(first level),the combined pollutions of heavy metal element from the bed mud of the Wuliangsu lake are relatively serious,and the main pollutant elements are Cu,Cd,Ni and Zn.There are a remarkable correlation between the total contents of Pb,Cd,As,Cu,Cr,Hg and Zn,which suggests a same origin of pollutants.Evaluation results of ecological risk index method show that the most parts of the lake belong to a mild pollution risk;three entrances of drainage irrigation channels belong to extreme sever pollutions risk;and other areas belong to severe pollution. |
