攀枝花钒钛高新区土壤重金属污染研究

Study on Heavy Metal Pollution in Soil of Panzhihua Vanadium-Titanium High-tech Zone

为了解攀枝花市钒钛高新区土壤重金属的污染程度,本研究采集测定了11家企业周边表层土壤Hg、As、Pb、Cd、Cr、V、Zn、Ni、Cu。结果表明,11家企业周边表层土壤整体呈轻度重金属污染,Cd、Pb、Cr、As在不同区域中出现明显的积累,化工、冶炼行业对土壤重金属污染影响较大。

In order to understand the pollution degree of heavy metals in the soil of the vanadium-titanium high-tech zone in Panzhihua City,Hg,As,Pb,Cd,Cr,V,Zn,Ni,Cu in the surface soil around 11 enterprises were collected and analyzed in this study.The results show that the surface soil around the 11 companies is slightly polluted as a whole,and Cd,Pb,Cr,and As accumulate in different regions,the chemical and smelting industries have a greater impact on soil heavy metal pollution.
