摘要
对黎平县工业区某硅厂土壤重金属Cu、Zn、Pb、Cd含量进行初步调查,并采用单因子污染指数法、内梅罗综合污染指数法对土壤重金属进行污染评价。结果表明:该硅厂周边土壤已受到一定程度的重金属污染,以Cu污染最为严重,已达中污染水平,其余3种元素为轻污染。
The contents of Cu, Zn, Cd and Pb in the soil of Liping industrial district were investigated and evaluated by using the single factor index and Nemerow integrated index method. The results showed that the soil in Liping Industrial District was polluted by heavy metals, with medium pollution degree of Cu and slight pollution of others.
