| 摘 要： | 以四川省内江市双桥乡为研究区域,调查分析各类土壤中重金属（Cu、Pb、Zn、Cd、Cr、As、Hg、Ni）含量情况。采用单因子污染指数、内梅罗综合污染指数和富集因子评价方法,对土壤重金属污染状况进行评价。研究结果表明,该地区Cd、Cr、Cu、Ni、Pb、Zn元素平均含量高于成都经济区、四川省、中国土壤背景值,有一定程度的Cd、Cr、Cu、Ni、Pb、Zn富集,Hg元素有个别样点含量偏高,并且单因子重金属的污染程度依次为：Cd〉Ni〉Zn〉Cu〉Cr〉Pb〉As〉Hg,Cd在绝大部份区域存在轻微污染,由内梅罗污染指数和富集因子评价得出区域综合污染程度为轻度。

| Abstract: | This article is based on the survey and analysis about the content of heavy metals (Cu、 Pb、 Zn、 Cd、Cr、As、Hg、Ni) in a variety of soil. The study geographic area is Shuangqiao village, Neijiang city in Sichuan Province. The method of single factor index, Nemoro index of pollution and the method of enrichment factor assessment were adopted to assess the condition of heavy metals pollution in soil. The results show that the average content of Cd、 Cr, Cu、 Ni、 Pb、 Zn elements in this area are above the background level of Chengdu economic region, Sichuan Province, China soil. There are Cd、 Cr, Cu、 Ni、 Pb、 Zn enrichment to some degree, and the Hg element content is on the high side in several sampling points. The single factor heavy metal pollution extent is:Cd>Ni>Zn>Cu>Cr>Pb>As>Hg, and there exists a small extent Cd contamination in most area. Nemoro index of pollution and the method of enrichment factor assessment reach that the area synthetic contamination degree is mild. |
