- Abstract
Based on determination of the contents of soil nutrients elements and heavy metals for the four tin mine tailings (Niubahuang, Laochang, Kafang and Southern) in Gejiu, the heavy metal pollution of four tin mine tailings were assessed with the single contamination index method, the comprehensive contamination index method, the geoaccumulation index method and the potential ecological risk index method. The results showed that:(1)Soil pH of four tin mine tailings was more than 7.5, for alkaline soil. The soil fertility of four tin mine tailings was poor, the soil organic matter soil fertility levels were between VI level, total N P K and available P index of soil fertility level basically in III ~ VI, soil fertility index of K available were grade II, the soil fertility order: the Laochang > the Kafang > the Southern > the Niu banghuang. (2)In the four tin mine tailings, the average contents of Mn, Cu, Pb, Cd and Zn were 5700.98mg/kg, 2041.19mg/kg, 7164.72mg/kg, 21.33mg/kg and 2146.81mg/kg. According to the mean size sorting are: Pb Mn Zn Cu Cd. According to the single contamination index and the comprehensive contamination index , all of heavy metal contamination grades were high pollution. According to the Hankanson potential ecological risk index evaluation results: Mn and Zn minor ecological risk, Cu, Pb and Ca for strong ecological risk. Cumulative Index to evaluate the results: Mn pollution level was 3, Cu, Pb, Cd contamination level were 6, Zn pollution level was 4 to 5.
