摘要
为了比较不同的土壤重金属污染评价方法,利用单因子污染指数法、地质累积指数法及内梅罗综合污染指数法,对潼关县某金矿排水沟沿线土壤样品中5种重金属(Sb,Sn,Pb,Ti,Ba)进行了污染评价对比。结果表明:单因子污染指数和地质积累污染指数评价结果均表明,5种重金属污染程度依次为Sb>Sn>Pb>Ti>Ba;内梅罗综合污染指数评价结果显示,35个样区均处于严重污染状态;3种方法中地质累积指数法较适宜对所选矿区的污染评价。
To make a comparison of various evaluation methods of heavy metals in soil,the single factor pollution index,geo-accumulation index and Nemerow index were adopted to assess the pollution of five heavy metals(Stibonium,Stannum,Lead,Titanium,Barium) along mine drainage in Tongguan County.The results showed that according to the assessment results of the single factor pollution index and geo-accumulation index,the pollution degree for five kinds of heavy metal was as following: StiboniumStannumLeadTitaniumBarium.According to the assessment result with Nemerow index,all soil samples were in gross pollution degree condition.Among the three kinds of evaluation methods,the geo-accumulation index was suitable for the evaluation for this mine area.
