摘要

分析了重庆市武隆区的10个土壤样品的As、Cd、Cr、Hg、Pb 5种重金属元素的全量。结果表明,重庆市武隆区土壤空间强变异的重金属元素有Hg(46. 70%)、As(42. 25%)、Cd(74. 79%);土壤中的Hg、As、Cd出现超标情况,超标率分别为20%、20%、30%;五类重金属的内梅罗综合污染指数从低到高排序依次为:Pb         The full amount of 5 kinds of heavy metal elements,such as AS,Cd,Cr,Hg and Pb,was analyzed in 10 soil samples in Chongqing Wulong district. The result shows,Hg,As and Cd has significant spatial variations with the figure of 46. 70%,42,25% and74. 79%,their contebts in the soil exceeded the standard with the rates of 20%,20% and 30% respectively. The Nemmerrow pollution index of five types of heavy metals was sorted from low to high in order: PB < CR < AS < HG < CD,where Hg and Cd achieved mild contamination,As reached alert level. Heavy metals in three places reach light pollution levels.
