Distribution and Occurrence of Polycyclic Aromatic Hydrocarbons in the Environment of Huainan Mining Area and Its Environmental Impact

Abstract

Based on the theories and methods of analytical chemistry, environmental chemistry and organic geochemistry, the composition, content, distribution, migration and transformation of polycyclic aromatic hydrocarbons (PAHs) in raw coal-coal gangue-weathered coal gangue- gangue mixed soil- soil series and water in Huainan mining area were tested and studied. The influence of coal gangue dump on surrounding environmental media such as soil and water body during weathering process is discussed. The environmental impact of polycyclic aromatic hydrocarbons (PAHs) was evaluated by comparing the content changes of PAHs in different sampling areas and samples, which provided scientific basis for the prevention and control of environmental pollution in mining areas.
