| 摘 要： | 悬移质泥沙在天然河流中空间分布非常广,由于它的颗粒非常小,具有巨大的比表面积,同时其表面通常还存在许多活性物质,它们对进入水环境系统的重金属具有强烈的表面物理、化学和生物等作用,是重金属迁移、转化的主要载体,本文应用HANKANSON潜在生态危害指数法对滇东南矿区河流悬移质重金属潜在生态风险进行评价,结果表明:悬移质中产生生态危害的主要重金属为Cd和As等,该地区受重金属污染强度顺序依次为:Cd(As(Cu(Pb(Zn。研究时段内该河流悬移质重金属污染属于很强生态危害。

| Abstract: | The suspended sediment distributes widely in natural rivers because of its small particle size,and huge specific surface area.The active materials on the surface of sediments have significant physical,chemical and biological impacts on the heavy metals discharged in the water bodies.Therefore,sediment is an important media for heavy metal removal and transform.Based on the data of heavy metals in the suspended sediment of rivers in south-east Yunnan mining areas,the potential ecological risk of heavy metals... |
