土壤重金属源解析研究方法与应用

Analytical Method and Application of Soil Heavy Metal Source

以肇庆市端州区为例,运用主成分分方法对当地的表层土壤中重金属污染物的来源进行分析。结果表明,肇庆市端州区表层土壤中不同重金属元素来源明显存在着差异,其中重金属Cu、Zn、Cr、Hg主要来源于工业;Pb主要来源于城区的交通运输污染;Ni来源于冶炼行业的污染排放最后由大气沉降到表层土壤当中。今后土壤环境将会是污染整治的一个重要方面,因此清楚了解土壤中污染的来源,就可以使整治更加有成效,使土壤环境趋于正常。

Taking Duanzhou District of Zhaoqing City as an example, the main component method was used to analyze the sources of heavy metal pollutants in the local surface soil. The results show that there are obvious differences in the sources of different heavy metals in the surface soil of Duanzhou District, Zhaoqing City. The heavy metals Cu, Zn, Cr and Hg are mainly from industry;Pb is mainly from urban transportation pollution;Ni is from the smelting industry. The pollution discharge is finally settled by the atmosphere into the topsoil.In the future soil environment will be an essential direction of the pollution treatment, so clear realize the source of pollution in the soil, will make the treatment more efficacious, let the soil environment tend to normal.
