摘要:
随着不锈钢产业的发展,其生产加工过程中产生的含重金属的废水、废气及固体废弃物对周围土壤及地表水环境的影响也日益显现。选择江苏省不锈钢产业集聚区内溱东镇土壤为研究对象,对区域内63个采样点进行分析,发现区域内土壤中Cr、Zn、Cd、Pb质量分数平均值均未超过国家土壤环境质量标准的二级标准要求,重金属污染程度由大到小的顺序为:Cd>Ni>Cr>Mn>Zn>Pb,并且通过SPSS13.0统计软件对分析数据进行相关性分析,数据表明,土壤中重金属Cr、Fe、Cd、Ni、Mn来自不锈钢产业的可能性较大。

Abstract:
With the development of stainless steel industry, the effect on water and soil, which is caused by waste water, waste gas and waste solid in the production of stainless steel, had been increasing. Taking Qindong town in this zone as an example , we found that none of Cr、Zn、Cd、Pb mass in the studied region had overrun the Grade Ⅱof national《Environmental Quality Standard for Soil》(GB 15618-95) and the descending order of Heavy Metal pollution was: Cd>Ni >Cr>Mn>Zn>Pb. At the same time , the results on the Pearson correlation suggested Cr、 Fe、Cd、Ni、Mn pollution in the soil more likely come from the stainless steel industry.
