英文摘要: The underground coal seam fire in the Wuda, Inner Mongolia of china is one of the most serious coal fires in the world with a history over 50 years and endangers the neighboring downwind urban area. To investigate the potential mercury emission and migration from the coal seam fire, in situ real-time measurement of total gaseous mercury (TGM) concentration using Lumex RA-915+mercury analyzer were implemented on the fire zone and the urban area. The results show an average TGM concentration of 464 ngm-3 in the fumes released from surface vents and cracks on the fire zone, which leads to an elevated TGM concentration of 257 ngm-3 (211-375 ngm-3) in the near-surface air at the fire zone and 89 ngm-3 (23-211 ngm-3) at the peripheral area. The average TGM concentration in the adjoining downwind urban area of Wuda is 33 ngm-3. This result suggests that the coal seam fire may not only contribute to the global mercury inventory but also be a novel source for mercury pollution in the urban areas. The scenario of urban areas being adjacent to coal seam fires is not limited to Wuda but relatively common in northern China and elsewhere. Whether there are other cities under influence of coal seam fires merits further investigation. © 2013 Elsevier Ltd. Citation statistics:
