| 摘 要： | 对成都市农业土壤中七种重金属元素Pb、Hg、Cr、As、Cu、Zn和Cd进行了测定和研究,并进行了潜在生态风险评价。结果表明,成都市农业土壤重金属元素含量分别为:Pb 77.27mg/kg,Hg 0.31 mg/kg,Cr 59.50 mg/kg,As 11.27 mg/kg,Cu 42.52 mg/kg,Zn 227.00 mg/kg,Cd0.36 mg/kg;重金属潜在的生态危害因子表明,Hg和Cd达到中等生态危害程度,Pb、As、Cu、Zn、Cr达到轻微生态危害;多种重金属的生态系统的潜在生态风险指数(RI)表明,成都市农业土壤生态危害级别为中等生态危害。

| Abstract: | Based on the data of heavy metals in farm soil in Chengdu,which including Pb,Hg,Cr,As,Cu,Zn and Cd,the potential ecological risk of heavy metals were analyzed and assessed.The results shows that the content of seven heavy metals Pb,Hg,Cr,As,Cu,Zn and Cd is 77.27 mg/kg,0.31 mg/kg,59.50 mg/kg,11.27 mg/kg,42.52 mg/kg,227.00 mg/kg,and 0.36 mg/kg;the contamination factor(E_r~i)of Hg and Cd is moderate,other heavy metals is light;the contamination level of farm soils are moderate. |
