In order to understand the effect of typical industrial enterprise on heavy metal content in around soil and the pollution status in the surround- ing residential area, the Authors investigated 5 typical industrial districts. The contents of Cu, Zn, Pb, Cd, Hg and As in soil of typical industrial parks were higher than that in the surrounding residential area. The pollution element varied among the industrial parks.
