摘    要:对杨家幛子钼矿区土壤重金属污染的情况进行了详细研究。选择土壤样本80个,采用HNO3-HF-HClO4混酸对土壤样品进行处理,运用等离子体发射光谱仪(ICP-AES)测定土壤样品中Pb、As、Hg、Cr、Cd、Zn、Cu、Ni、Mo的含量,全面系统地评价土壤重金属污染现状。结果表明,该矿区土壤重金属As、Cd和Hg污染较为严重,平均含量分别达154.13、74.92和3.06mg/kg。不同片区间存在明显差异,污染强度以矿山山沿污染最高,其次是运输区、选矿厂及矿区附近山地,内梅罗综合指数分别为59.98、59.33、52.14、42.44。

关 键 词:矿区  重金属污染  土壤污染  不同功能区

Abstract:This article has conducted thorough research on the heavy metals pollution in the soil of the Yang valley molybdenum ore areas.We choosing 80 soil samples and use HNO_3-HF-HCLO_4 to deal with the samples.The contents of Pb,As,Hg,Cr,Cd,Zn,Cu,Ni,Mo were analyzed by ICP-OES.The results indicted that the contents of As,Cd and Hg in the soil were 154.13mg/kg,74.92mg/kg and 3.06mg/kg.But the contents of heavy metals in different zone have distinct differences,the pollution intense of the sequence of the ore areas was the heaviest which Nemero index was 59.98,ranking of pollution intense of different zone from heavy to light is in the sequence of the transportation zone which Nemero index was59.33,the ore collection area which Nemero index was52.14 and the mountain near the mine which Nemero index was42.44.
Keywords:Mine  Heavy metals pollution  Soil pollution  Various zones
