摘　　要：对广安市石垭镇194份土壤样品中8种重金属元素(As、Cd、Cr、Cu、Hg、Pb、Zn、Ni)的含量进行了测试,并将结果与土壤环境质量标准(GB15618-1995)进行对比,结果发现Cd和Hg含量在局部地区超标;采用单因子污染指数和土壤综合污染指数作为评价方法与标准,对项目区内重金属元素的污染状况进行了评价,结果显示项目区并未受到8种重金属的污染,土壤总体尚清洁。8 heavy metal elements （ As, Cd, Cr, Cu, Hg, Pb, Zn, Ni） in 194 soil samples in Shiya town of Guang＇ an city were determined. Results indicated that the content of Cd and Hg in some areas was over standard according to the soil environmental quality standard （GB15618 -1995）. The heavy metal pollution status in project area was evaluated with the single factor pollution index and comprehensive pollution index. The results showed that the soil had not been polluted by the 8 heavy metals.
