依据单项污染指数法和内梅罗综合污染指数法来评价土壤重金属污染程度。
By adopting both the single factor index method and Nemerow multi-factor index method, the pollution indices were calculated to assess pollution extent.
结果表明,以单因子污染指数评价,在118个表层土壤样品中,有42个样品的重金属含量超标,超标率为35.6%。
Among the 118 surface soil samples, 42(corresponding to 35.6%) were above the national standards when evaluated with single factor index method.
