Characteristics of heavy metals release from coal waste and potential ecological risk assessment of contaminated soil around coal waste piles were studied.The results showed that:(1)Residual fraction was the main fraction of heavy metal in coal waste
such as Cu
Zn
Pb
Cr and Cd accounted for 56.86%
53.27%
72.01%
68.61% and 75.93%
which could not easily release from coal waste
but few acid soluble fraction and oxidizable fraction could release and contaminate the soil;(2)Soil heavy metal contents decreased wi...
