孝义铝矿复垦土壤重金属污染潜在生态风险评价OA北大核心CSCDCSTPCD
Potential ecological risk assessment of heavy metals in the reclaimed soil of Xiaoyi Bauxite Mine
为了解和评估复垦区土壤重金属污染风险,采用Hakanson潜在生态风险指数(The Potential Ecological RiskIndex)法,对孝义铝矿复垦3年后的土壤中7种(Cd、Cr、Cu、Pb、As、Ni和Zn)重金属质量分数和潜在生态风险进行评价.结果表明:复垦土壤中,主要超标重金属元素是Cd,7种元素均存在累积效应.污染源主要有复垦用土、农业生产和粉尘等外来影响;其中,Cd、Cr和As 3种元素具有伴随复合污染现象.Cd的污染指…查看全部>>
[Background] Mineral is a key resource for social and economic development.However,environment issues from mining are more and more serious.Shanxi is a resource province,a lot of land were destructed during the mining,and should be reclaimed after mining.In order to understand the potential pollution characteristics and the pollution risk of heavy metals in reclaimed soil,the heavy metal elements Cd,Cr,Cu,Pb,As,Ni and Zn of reclaimed soils at Xiaoyi Bauxite …查看全部>>
