不同类型土壤及蔬菜中的重金属分析

Analysis of heavy metals in different soil types and the vegetables

为了研究不同类型土壤及种植蔬菜中重金属含量,选择两块试验田,种植不同品种蔬菜,分析了土壤及蔬菜中的重金属含量。试验结果表明：土壤深度为0~80 cm时,两种类型土壤中的重金属Pb、Cu、Zn、Cd、Cr含量随着土壤深度的增加而减小;A区土壤Pb、Cu、Zn含量比B区高;种植的小青菜、小白菜中Pb、Cd、Cr含量A区大于B区;果实类蔬菜对重金属的累积量小于叶菜类。本研究成果可为土壤污染治理提供参考,为人体健康提供依据。

In order to study the content of heavy metals in different soil types and the vegetables planted,this paper chooses two plots to plant different varieties of vegetables, and analyzes the heavy metals content in the soil and vegetables. The results show that within the scope of 0 cm to 80 cm,the concentration of heavy metals Pb, Cu, Zn, Cd, Cr in two types of soil decreases with the soil depth. The content of heavy metals Pb, Cu,Zn in A area is higher than B area. The content of heavy metals Pb, Cd, Cr in small brassinca chinensis and small cabbages planted in A area is more than that in B area. Heavy metals accumulation amount in fruit vegetables is less than leaf vegetables. This study provides reference for the soil pollution control and the basis for human health management.
