Study on Occurrence Characteristics and Natural Degradation of Polycyclic Aromatic Hydrocarbons in Mined-out Area of Northern Shaanxi Coal Mine

Abstract

The rapid economic development is accompanied by the rapid consumption of energy. Coal plays an important role in China's energy production. With the continuous exploitation of coal resources, the mined-out area of coal mines has continued to increase. PAHs are common organic pollutants in coal mines. With the gradual deepening of the research on PAHs, the natural degradation of indigenous dominant bacteria has become the best choice. The application of microbial treatment to repair PAHs-contaminated soil, and the research on the relationship between PAHs and degrading microorganisms are great significance to the bioremediation of PAHs pollution.
