城市表层土壤重金属污染分析研究

根据某城市土壤表层中的8种重金属Cu、Pb、Cd、Hg、As、Cr、Ni、Zn的浓度数据,利用地统计学原理方法,研究了不同功能区土壤重金属的污染特征。结果表明Cd、Cu、Hg、Pb和Zn在工业区和主干道路区浓度超标,并且这几种元素的富集系数偏高,说明污染来源主要是工业生产、汽车尾气排放及汽车轮胎磨损等。此研究对城市土壤重金属污染治理及修复、重金属污染重点行业污染控制等提供参考。

Analysis on Heavy Metal Pollution in Urban Surface Soil

According to the concentration data of eight heavy metals in soil, Cu, Pb, Cd, Hg, As, Cr, Ni, Zinc, this paperstudies the characteristics of different functional areas of soil heavy metal pollution using the method of statistical principle. Resultsshowed that Cd, Cu, Hg, Pb, and zinc in the industrial area and the chroma of the trunk road area are high, and these elements en-richment coefficient on the high side, showing that the pollution source is mainly in industrial production, vehicle emissions and au-tomobile tires, etc. The study on urban soil heavy metal pollution control and repair, heavy metal pollution key industries such aspollution control to provide the reference.
