摘要
为了解广西某铅锌矿区(110°34'40″E,23°53'20″N)土壤重金属污染特征,采集45个土样,对6种重金属污染物含量分别进行测定。结果表明,土壤p H平均值为5.05,呈弱酸性,调查区域土壤主要受到As和Pb重金属污染。Hakanson潜在生态风险指数评价法的结果表明,6种重金属潜在生态危害系数均值大小顺序为:As>Pb>Cd>Cu>Zn>Cr。与国内其他铅锌矿区土壤相比,调查区土壤重金属污染主要分布于表层土壤。土壤重金属健康风险评价结果表明,As和Pb的人群致癌健康危害较大,As和Pb重金属健康风险水平大于10-4。
In order to understand the pollution for the soil surrounding lead and zinc industry in Guangxi(110°34′40″E,23°53′20″N),the contents of 6 heavy metals in 45 soil samples were analyzed.The results indicated that the the soil had weak acid,the mean pH value is 5.05.The soils were polluted by As and Pb.E r i potential ecological risk was characterized by the order of As>Pb>Cd>Cu>Zn>Cr.Compared with other soils surrounding lead and zinc industry in China,the heavy metals were mainly distributed in surface soil in the survey area.Health risk assessment suggested that As and Pb were the greatest ecological risk in these elements.The health risk of As and Pb was higher than 10-4.
