| Abstract: | Soils are digested with nitric acid, determining cadmium, lead, copper, zinc, nickel and chromium by AAS. Using Single factor pollution index method and N.L. Nemerow integrated pollution index evaluating pollution status of heavy metals in Yueyang areas. The results show that the content of heavy metals in Yueyanglou District and Yunxi District are in middle level pollution levels, Linxiang City is polluted lightly by Cd, Pb, Zn; Xiangyin County is polluted by Cd, Cu, Cr; Yueyang County shows warning line because of pollution of Ni; One of the Pingjiang County＇s sampling points has light pollution of Cd; Huarong County and Junshan District haven＇t been polluted yet. |
