摘  要:
选取太原市5个无公害蔬菜基地,采样化验分析温室土壤中重金属砷、汞、铅、镉、铬含量。分析结果表明:各基地土壤重金属As,Hg,Pb,Cd,Cr含量不一,但均符合有关标准,未出现超标现象;0~20 cm土层的重金属含量和单项污染指数高于20~40 cm土层,其中As的单项污染指数最高;3个无公害蔬菜基地表层土壤的综合污染指数接近警戒级,下层土壤尚属安全清洁状态。

摘  要:
The paper investigated the development condition of Taiyuan pollution-free vegetable bases and chose five representatives of them,make laboratory analysis of greenhouse soil heavy metals As,Hg,Pb,Cd,Cr in the soil by the sampling.We drew our conclusions as follows: The proportions of heavy metals As,Hg,Pb,Cd,Cr in the soil of five bases are not the same,but it conforms to the related standard,and does not exceed the standard;The heavy metal contents and individual pollution indexes were higher in 0~20 cm soil horizon than in 20~40 cm horizon,and As'pollution index is the highest among them;The synthesis pollution index of the surface layer soil in 3 pollution-free vegetable bases approaches the cordon of the comprehensive pollution index,but the lower layer soil still is under the pollution-free condition.
