钢厂及周边土壤重金属分布特征及污染评价分析

Distribution Characteristics and Pollution Assessment of Heavy Metals in Steel Mills and Surrounding Soil

为进一步探究钢厂生产过程对周边土壤环境带来的重金属污染问题,以山西南部某大型钢铁厂及其周边农田区域为研究对象,通过采样和实验分析,初步确定区域内的土壤重金属含量,而后以ARCGIS为辅助工具,对数据进行处理,以明确钢厂及周边土壤重金属分布特征。在此基础上,进一步应用潜在生态风险指数法对目标区域的土壤重金属污染程度进行评价,结果显示,Cd、Pb和Cu三类重金属元素的影响最为突出,需在后续工作中予以重点关注和治理。

In order to further explore the heavy metal pollution caused by the production process of steel mills on the surrounding soil environment,a large steel mill in southern Shanxi and its surrounding farmland area were taken as the research object.Through sampling and experimental analysis,the soil heavy metal content in the area was preliminarily determined.Later,ARCGIS was used as an auxiliary tool to process the data and clarify the distribution characteristics of heavy metals in the steel mill and surrounding soil.On this basis,the potential ecological risk index method was further applied to evaluate the degree of soil heavy metal pollution in the target area.The results showed that the impact of Cd,Pb,and Cu,the three types of heavy metal elements,was most prominent and needed to be given special attention and treatment in subsequent work.
