Pullution of aromatic compounds and elements of a coal gangue dump from Fengfeng Coal Mine 5, China

Distribution and occurrence of aromatic compounds and elements in the coal gangue dump from Fengfeng Coal Mine 5 and their influences on the environments have been studied in this paper. The samples were taken from the coal gangue dump, coal waste water stream and soil surface samples. These samples were analyzed by organic and inorganic methods. The results indicate that the coal gangues contain abundant harmful substances like aromatic hydrocarbon compounds, sulfur and trace elements. These harmful substances have influenced around area. In the soil surface, they influence the environments at least 750 m far from the coal gangue dump. In the waste water stream, they influence the water quality at least 2500 m far from the coal gangue dump.
