摘 要: | [目的]测定广西主要农产品基地土壤重金属Pb、Cd、Cr、Hg、As的含量,并结合土壤重金属评价标准和土壤污染分级标准,采用单因子污染指数法和M.L.内梅罗综合污染指数法进行污染评价。[方法]选取广西6个无公害农产品基地,采样分析土壤中重金属As、Hg、Pb、Cd、Cr含量。[结果]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。[结论]无公害产地的土壤环境质量良好,未受污染,完全符合评价标准要求。适宜发展无公害农产品。

Abstract: | [ Objective ] To study the accumulation of Pb, Cd, Cr, Hg, As. Combined with heavy metal soil contamination evaluation criteria.and grading standards, pollution was evaluated with single factor pollution index and M.L. Nemerow pollution index. [ Method] The development condition of Guangxi pollution-free agricultural products bases was investigated and six representatives of them were selected to make laboratory a- nalysis of soil heavy metals As, Hg, Pb, Cd, Cr in soil by sampling. [Result] The proportions of heavy metals As, Hg, Pb, Cd, Cr in the soil of six bases are not the same, but it conforms to the standard, and does not exceed the standard. [ Conclusion ] Soils in pollution-free bases are suitable for the development of pollution-free agricultural products. |
