| Abstract: | Eighteen soil samples of the agricultural produced in Yuexi County was analyzed,and the soil quality was conducted a comprehensive evaluation.Soil quality was evaluated in accordance with the relevant national standards.The smallest single factor pollution index of soil heavy metal is Pb,followed by As,Hg,Cu and Cr;the largest pollution index is Cd reached 1.675,and there are 15 soil samples existed in Cd pollution.The soil integrated pollution index of Cd,Hg,As,Pb and Cr and Cu is 1.675,0.423,0.413,0.226,0.760 and 0.604,respectively,indicating that the production base of soil is in the light pollution of Cd,and there is a potential hazard of Cr. |
