Title: Distribution and pollution evaluation of heavy metals in mine soils of Chang-Zhu-Tan city region
Abstract: The concentration of Cd,Pb,Cu,Mn,Zn in mine soils of Chang-Zhu-Tan city region were measured,and their pollution state was evulated by using the single-factor polluted index and N.L.Nemerow integrated polluted index.The results indicated that the concentration of N,P,K was not arrived the normal level in which plants would develop.Compared with the mean contents of these five heavy metals in soils in Hunan province,the Pb,Cd,Mn,Cu,Zn contents were obviously higher in four studied mines.The integrated polluted index of these five heavy metals were more than 3,the highest index was 931.2,the lowest index was 7.8.Cd heavy metal was mostly polluted in all soils.
