| Abstract: | The contents of Cu,Zn,Pb,Cd in vegetable garden soils in suburbs of Nanning City were analyzed in our laboratory in order to evaluate pollution of heavy metals on farmland through a survey.It was discovered that the average contents of the heavy metals were generally higher than background values in soil of Nanning City.This is mainly due to the fact that the vegetable garden soils have been polluted by Zn and Cd.It was also found that Cd pollution was critical,and seriously by indicating that: the rates of exceeding controlling standard promulgated by government for Cd and Zn were 38.6% and 10.5%,respectively.The pollution tendency of the heavy metals in the studied soils was in the following orders: near suburbs>distant suburbs. |
