A Comparative Study of Heavy Metals Enrichment Characters of Urban Soils in Shanghai,Urumqi and Changji

LIU Yu-yan1,LIU Hao-feng2(1.ChangJi College,Changji Xinjiang 831100,China;2.Environment Monitoring Station of ChangJi Prefecture,Changji Xinjiang 831100,China)  
Results were presented from a comparative study of heavy metal enrichment characters in Urban Soils of three cities in China.The first(Shanghai) was a super large urban area(population of 18.88 million),the second(Urumqi) was a large urban area(population of 2.31 million),the third,Changji,a small one(population of 0.35 million).Several trends were identified: contents of Cr,Cu,Pb,Zn were higher than background values,contents of Mn,Fe were close to background values.Since discharged of industry contamination,and current traffic movements,industrial and urban processes entirely influenced heavy metals concentration,the size of city were not therefore reflect direct enrichment level of heavy metals in urban soil.The main contaminated sources varied with the cities resulted in different of heavy metals distributing in different functional areas except for Mn and Fe.Contents of active fraction in heavy metals were not consistent with the contents of heavy metals.
