Lead content of urban soils in China

This paper presents the background value of Pb content in soils from Wuhan,Lanzhou,Changchun andQingdao cities in China,the soils were contaminated by either of smelter,automo- bile,chemical industries,and traffic road. The degree of Pb pollution in the four cities is different,Wuhan >Qingdao > Changchun>Lanzhou. The heavier pollution is where it is nearer to the pollution source. The Pb pollution in Wuhan,Qingdao and Changchun is similar to that of Ber- mingham.
