The naturally occurring primordial radionuclides in coals might exhibit high radioactivity, and can be exported to the surrounding environment during coal combustion. In this study, nine coal samples were collected from eastern Yunnan coal deposits, China, aiming at characterizing the overall radioactivity of some typical nuclides (i. Th have high(More)
This work investigated the spatial profile and source analysis of polycyclic aromatic hydrocarbons (PAHs) in soil that surrounds coal-fired power plants in Xuzhou, China. High-throughput sequencing was employed to investigate the composition and structure of soil bacterial communities. The total concentration of 15 PAHs in the surface soils ranged from(More)
The large-scale coal mining has caused serious environmental pollution and ecological damage in the coal mining areas in China. The serious conditions are listed as below: the geological disasters such as landslide, dilapidation, mud-rock flow and so on aroused by mining subsidence; the side effects such as land occupying, side sloping, filtrating and(More)
Fluorosis is the most widespread and serious endemic disease in the abandoned Yellow River flooding delta of East China. Regional geochemical investigation indicates that host rocks containing F rich minerals of Archaean and Proterozoic stages are the geochemical source for the high fluoride groundwater. Over 1500 times flooding of the Abandoned Yellow(More)
