| 摘 要： | 基于对新乡市近郊农田土壤的采样分析,利用潜在生态危害指数法及因子分析法,分析研究了土壤中重金属的潜在生态风险程度,内在关联性及其可能的污染来源.结果表明:土壤中重金属Cr与Cu的含量在国家土壤二级标准以内,而Cd,Ni与Zn含量明显超标；土壤重金属可能引起严重的综合生态风险,其中Cd,Ni的潜在生态风险等级分别隶属于极... |

| Abstract: | Contents and potential ecological risk of heavy metals in the Suburban Farmland soil of Xinxiang city have been researched based on the index of Hakanson potential ecological risk and factor analysis.The results show that the gross concentrations of Cr,Cu are lower than the nation standard,by contrast,the gross concentrations of Cd,Ni,Zn exceed the nation standard obviously.The degree of potential ecological risks indicated that Cd and Ni reached the higher degree of potential ecological risk,stronger ecolo... |
