Abstract:In order to quantitatively evaluate pollution degree of heavy metal in soils near the vanadium tailings pond, the geoaccumulation index method, nemerow index method and potential ecological hazard index were used to comprehensively evaluate pollution degree of heavy metal. The results showed that the heavy metals such as Cd, Ni, As, Cr, Cu, Zn and Pb contents were accumulated in soils near the vanadium tailings pond and the soils were polluted according common soil evaluation standard, with the most serious contamination by Cd, followed by Ni and As. In general, Cd is the most important pollution factor in the soils near the vanadium tailings pond, followed by Ni and As, while other heavy metal elements are not the primary factors. Ecological risk assessment showed that Cd and Ni are the main ecological hazard elements, Cd is mainly at high risk, and Ni is at moderate risk. The influence of the vanadium tailings pond on the surrounding region was indispensable, the prevention and control of heavy metal pollution should be strengthened.
