Analysis on the status que and causes of fluorine and acid pollution around coal-rich areas in China
Fluorine pollution is widespread and fluorine pollution overlaps with coal-bearing areas in China, while sulfur, which is associated with acids, is a coal-based pollutant.This paper summarizes the present situation of coexisting fluorine and acid pollution in typical coal-rich areas in China.Then th...

| description | Fluorine pollution is widespread and fluorine pollution overlaps with coal-bearing areas in China, while sulfur, which is associated with acids, is a coal-based pollutant.This paper summarizes the present situation of coexisting fluorine and acid pollution in typical coal-rich areas in China.Then the synergistic mechanism that sulfur in coal is oxidized to acid, and acid promotes fluorine activation, migration, and release in the form of hydrogen fluoride is expounded.On the basis of this, different cooperative models of fluorine and acid pollution in different areas are proposed.The surface fluorine and acid pollution at the boundary of Yunnan, Guizhou and Sichuan province in southwest China are mainly caused by extensive natural weathering in the coal-bearing strata, which is a natural factor, while the coal-burning endemic fluorosis is caused by the superposition of natural factors and human improper utilization.The surface fluorine and acid in the sheep fluorine poisoning area in the northern Helan Mountain of Ningxia are mainly caused by the long-history of coal exploitation and domestic coal burning, along with the spontaneous combustion of coal, which is man-made.Analogously, the high-fluorine and high-acid in Wuda, Inner Mongolia, is caused by coal mining or the joint effect of the increased coal fire and industrial parks. |
