新疆东天山北坡工业带土壤重金属污染评价

本文选择新疆东天山北坡阜康市和吉木萨尔县工业带作为研究区，对研究区内的41个样点的土壤进行采样及室内试验分析，测定了0-10cm深度土壤中的Hg、As、Zn、Cu、Cr、Pb六种重金属的含量，并将样点分为工厂周边、矿区周边和农田区三个类型区，采用了多种方法对六种重金属的污染程度和等级进行分析和评价。结果表明：在工厂周边，As、Cu、Pb、Zn、Hg五种元素均有不同程度污染且受人为因素影响较大，其中As和Pb污染较为严重；在矿区周边，As、Pb、Zn、Hg受人为因素影响较大，其中As元素污染较重；在农田区，仅Pb与As两种元素处于轻微污染，整体受人为因素影响较小。

Analysis on soil heavy metal pollution assessment in the northern slope of eastern Tianshan Mountains industrial belt in XinJiang

In this paper, the industrial zone in the region of Fukang and Jimusar in the northern slope of eastern Tianshan Mountains in XinJiang was selected as study area. By measuring six heavy meatal elements which include Hg,As,Zn,Cu,Cr and Pb in soil, we use multi-methods to analysis the pollution status and evaluate the pollution degree of the soil heavy metal in the area around the plant, the area around coal mine and cropland. The result indicates that, in the area around the plant, five elements affect by human factor strongly which were As, Cu, Pb, the most serious pollutants were As and Pb. In the area around coal mine, the As,Pb,Zn,Hg were affected by human factors strongly and the As was heavily polluted .In cropland, Pb and As were slight pollution, the whole area was barely influence by human factor.
