Abstract:We select a large coal waste rock dumps in Guangxi Heshan , study the characteristics of the distribution of polycyclic aromatic hydrocarbons (PAHs) in its surrounding soil and carry on a soil quality evaluation. Soil samples were collected in different distance and different depth from the dumps.

The results show that in the plane… Show more
