- W2883003080 abstract "The coal mining subsidence area in Huainan is a specific but common ecosystem in China. Not a lot of researches focusing on persistent organic pollutants like polycyclic aromatic hydrocarbons (PAHs) in this area have been done. In order to investigate the concentrations, sources, environmental fate of PAHs and its distribution factors, Yangzhuang and Xieqiao coal mining subsidence areas in Huainan, China were determined as the object of the research, where samples from different depths of soil and sediments were collected to detect and analyze PAHs with Gas Chromatography-Mass Spectrometry. The result showed that the 16 PAH compounds were all detected with a detection rate of 100%. The concentrations of PAHs at different depths of the soil and sediments of Yangzhuang were in the range of 42.1-22149.0 and 44.0-7644.2 ng/g, respectively, and in Xieqiao which were in the range of 17.8-1617.7 and 35.7-264.6 ng/g, respectively. Through comparing the results about spatial interpolation analyses of two subsidence areas, we found that PAHs pollution in soil was heavier than that in sediments of the subsidence areas with relatively small man-made interference. Man-made pollution had a great influence on the vertical distribution of PAHs in the subsidence areas. The PAHs with three or four rings dominated in the areas. Using diagnostic ratios, we found PAHs came from mixed pollutions including the combustion of coal and traffic pollution. As for the influence factors, based on regression analysis and Pearson correlation analysis, the increase of organic matters (OM) and total organic carbon (TOC) favored the deposition of PAHs and had a positive impact on the vertical distribution of PAHs." @default.
