摘要
The distribution and modes of occurrence of Cu,Pb,Zn,Cd and Hg in the soil and their content in the water were analyzed in this paper.It is found that the soil and water of the study area was heavily polluted by Cu,Pb,Zn,Cd,Hg and other heavy metals.According to the National Environmental Quality Standards for Soil,no places in Baiyin attained grade Ⅰ of quality of Cd in surface soil,while places of grade Ⅲ,Ⅳ account for 82.39% of the study area,so Cd pollution is very serious.An investigation was made on the sources of Cu,Pb,Zn,Cd and Hg,which shows that the major sources of pollution are non-ferrous metal smelting,processing and heavy chemical industry,followed by coal,garbage and car exhaust emissions.
