Ultrafine ash aerosols from coal combustion: Characterization and health effects

The partitioning behavior of trace element and its distribution in the surrounding soil of a cement plant integrated utilization of hazardous wastes

“…On the other hand, the emitted trace elements can also be adsorbed onto the airborne particular matter (PM 2.5 or PM 10 ) and suspend in the air, which can be directly inhaled by human and exert detrimental effects on human organs (lung, bronchus, and respiratory tract) (Linak et al 2007). It has been reported that the workers who work in the cement plant were found to have higher risks of lung, bladder, and laryngeal cancer than the general population (Dietz et al 2004, Smailyte et al 2004.…”

Design and Characterization of a Two-Stage Human Subject Exposure Chamber

“…Ultrafine coal ash PM (Ͻ0.5 m diameter) is known to contain a measurable amount of thiophenic compounds that are stable at temperatures over 900°C in air. 6,[32][33][34] Inorganic sulfides are also found as a byproduct of an incomplete combustion of coal even at temperatures as high as 1370°C in excess oxygen. Additionally, sulfites may have been produced, which would further contribute to the reconciliation of sulfur balance.…”

Physicochemical properties and potential health effects of nanoparticles from pulverized coal combustion

“…NPs are an important constituent part of PM 10 and PM 2.5 (particulate matter with an aerodynamic diameter less than or equal to 10 and 2.5 µm). Although insignificant on a mass basis, they account for a dominant fraction on a number basis [2] .…”

“…However, compared with PM 10 and PM 2.5 , the understanding of NPs is far from adequate, especially the formation, emission and potential health effects of NPs from specific sources. For example, though coal combustion is an important source of NPs, only a few researchers have conducted studies [7][8][9][10][11] of NPs from coal combustion.…”
