| 摘 要： | 以包头市表层土壤为研究对象,通过对市内不同功能区的221个表土的重金属Cu,Pb,Zn,Cr,Cd,Hg和As含量的分析测试,认为包头表层土壤污染以重金属Pb,Zn,Cd,Hg和As为主,且造成不同功能区表层土壤污染的重金属种类存在明显差异,工业区以Pb,Zn,Cd,Hg和As为主,市区以Pb为主,郊区以Cd,Hg为主,农村土壤以Hg的点源污染为主。表层土壤的潜在生态风险评价结果表明,工业区土壤的污染程度明显要高于其它地区,局部地区已出现极强污染,其次为郊区,市区和农村地区。 |

| Abstract: | Heavy metal content of Cu,Pb,Zn,Cd,Cr,Hg and As was analyzed for the total of 221 surface soil samples taken from the different functional areas in Baotou City.The result indicates that the surface soil pollution was from heavy metal enrichment of Pb,Zn,Cd,Hg and As,but pollution characteristics have distinct diversity in the different functional areas.Pollutions in industrial area results from enrichment of Pb,Zn,Cd,Hg and As in the surface soil.Pollution in urb,suburb and rural area is from enrichment of Pb,Cd/Hg and Pb/Hg respectively.Risk evaluation suggests that some surface soils in industrial area are intensively polluted and arrived at most strong level,and the following is the suburb,the urban center and the rural areas,respectively. |
| Keywords: | pollution evaluation environmental risk surface soil heavy metal Baotou City |
