| 摘 要： | 基于潜在生态风险指数(RI)和风险评价代码(RAC),建立改进的潜在生态风险指数(MRI)。该方法考虑了单个重金属不同形态毒性的不同。以株洲霞湾港底泥为例,研究Cd、Cu、Pb、Zn的污染状况及其形态特征,并分别运用潜在生态风险指数、风险评价代码以及改进的潜在生态风险指数3种方法对霞湾港底泥进行风险评价。实验数据显示,霞湾港底泥的重金属污染严重。根据改进的潜在生态风险指数,重金属生态风险呈现CdPbCuZn递减的顺序。通过对比得出,改进的生态风险评价综合了潜在生态风险指数和风险评价代码2种方法的优点,评价结果更加可靠,能够为风险管理提供一定的理论依据。

| Abstract: | Modified potential ecological risk index(MRI) was proposed based on the potential ecological risk index(RI) and risk assessment code(RAC) by modifying an index.The modified index was relevant to the chemical speciation of heavy metals.Xiawan Port,a typical region contaminated by industrial production,was selected as a case study area.The total concentrations and chemical speciation of heavy metals in sediments of Xiawan Port were analyzed.The experimental data indicate that Xiawan Port is seriously polluted by heavy metals,especially by Cd.The risks of heavy metals are evaluated by RI,RAC and MRI,respectively.The resluts of MRI show that the risks of heavy metals are in the decreasing order of Cd>Pb>Cu>Zn,Comparison of results by different methods reveals that MRI integrates the characters of RI and RAC.MRI is recognized to be useful for risk managemnt of heavy metals in sediments. |
