| Abstract: | Contants of heavy metals (Cu Zn Cd Pb) in soils and vegetable from 12 main areas of vegetable plantation in Nanning city,were investisated and analyzed using the single fator index to evaluate heavy metal pollution in soils,and the vational vegetable sanitation standard in vestigation and evaluation of heavy metal pollution in soils and vegetable in part of Nanning planting areas,to evaluate those in the vegetable.The results showed that the planting soils were polluted with leavy metals Cu,Zn,Cd and Pb with an other of their pollution degrees determinted as Cd>Pb>Zn>Cu,that the contant of Cd and Pb in vegetable were higher than those of Cu and Zn,and that the contants of Cd and Pb in most of vegetables samples tested were higher than the national vegetable sanitation standard. |
