摘 要: | 采用地累积指数法、次生相与原生相分布比值法以及Hakanson潜在生态风险指数法从不同角度对雨水管道沉积物中重金属的污染风险进行了评价。地累积指数法的评价结果表明,不同重金属的污染级别为ZnCuCdCrPbNi。而次生相与原生相分布比值法以及Hakanson潜在生态风险指数法的评价结果表明,不同重金属的潜在污染效应关系和潜在生态危害系数大致排序均为CdCuZnPbNiCr。

Assessment on the pollution risk of heavy metal in the storm sewer sediments in Xicheng District, Beijing |

Abstract: | The potential pollution risks of heavy metal in the storm sewer sediments in Xicheng District of Beijing were evaluated by three methods of geological acumination index ( I_(geo)). ratio of secondary phase and primary phase (RSP) and the potential ecological index (PER). The assessment results of I_(geo) method showed that the contamination degree of 6 heavy metals follow the sequence of Zn>Cu>Cd>Cr>Pb>Ni, and the results assessed by RSP and PER methods reveal that the order of potential contamination risk and potential ecological index of 6 heavy metals was Cd>Cu>Zn>Pb>Ni>Cr. |
