芜湖市城市郊区土壤重金属污染的初步研究

通过对安徽省芜湖城市郊区四山、西江、鸠江、马塘４个典型农业区域土壤重金属Ａｓ、Ｈｇ、Ｐｂ、Ｃｄ、Ｚｎ、Ｃｒ污染现状的调查与分析，建立了城市郊区土壤重金属污染研究的一般程序和方法．在分析了各典型调查区域环境背景特征的基础上，计算出各区域土壤重金属污染指数，应用对应分析技术，研究了各调查区土壤重金属的污染特征．结果表明，芜湖城市郊区土壤重金属污染已相当显著，且各区域间土壤重金属污染具有一定的差异，总体上鸠江区较其他区域污染严重．各区域间Ｐｂ、Ｈｇ污染水平差异明显，但Ａｓ、Ｃｄ、Ｚｎ、Ｃｒ污染差异不大．根据研究结果分析了控制芜湖城市郊区土壤重金属污染的成因．

Heavy metal pollution in the soil in the suburbs of Wuhu City,Anhui Province

Pollution of As,Hg,Pb,Cd,Zn and Cr in the soil in the suburbs of Wuhu City,Anhui Province.Based on baseline study and measured concentrations of these metals in the soil,the pollution index was calculated.Correspondence analysis was applie.The results showed that the soil pollution by the heavy metals is quite obvious.Different features in pollution were revealed in different regions.In general,the pollution is more serious in Jiujiang area than in the other regions.There are significant difference in Pb and Hg pollution.
