摘要
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. Nemoro index of pollution and the method of enrichment factor assessment reach that the area synthetic contamination degree is mild.
