Characteristics and Risk Assessment of Soil Heavy Metal Pollution around Coal Producing Areas
In changzhi xiangyuan as the research area,to explore the villages,power plant,chemical industry,coal and coal preparation plant surrounding soil,Cr,Zn,As,Cd,Pb,Hg,Ni and Cu eight kinds of heavy metal difference accumulation characteristics,using Hakanson potential ecological risk index method to evaluate the soil of heavy metal pollution and ecological risk.The results show that the content of As in the surrounding soil is significantly higher than that of power plant,chemical,coal mines and coal preparation plant;the content of Hg in the soil around coal preparation plant is significantly higher than that of chemical and coal mines;the potential risk index of Hg and Cd is the highest,roughly above the medium potential ecological risk level.
