长株潭地区土壤环境地球化学研究

Environmental Geochemistry of Soil in Chang-Zhu-Tan Area

通过长株潭地区环境地球化学调查工作的实施,对长株潭地区土壤环境地球化学研究的工作方法进行了初步研究。结果显示,工业区重金属中Cu、Zn、Pb、As、Cd的污染较严重,尤其是Cd,这说明工业生产所产生的废水、废气、废渣是引起土壤中重金属污染的主要原因;各功能区重金属含量由高到低顺序为:工业区,居民区,商业办公区,休闲区,居民区和休闲区中重金属超标可能是由生活废水、生活垃圾和汽车尾气引起的。

The study on the soil environmental geochemistry in Chang-Zhu-Tan area shows that heavy metals in the industrial area were seriously polluted.These heavy metals include Cu,Pb,As and Cd,of which,the pollution of Cd is the most serious.Large amounts of castoffs were produced from the industry production,including various kinds of waste water,waste gas and wastes solid,which is the main cause of the pollution of the heavy metals in the soil.The content of the heavy metal in the all functional divisions is this...
