Fluorosis caused by indoor coal combustion in China: discovery and progress

Abstract: In this study, investigations into endemic fluorosis were conducted and fluorine concentration in environmental samples determined. In an indoor coal-combustion-type fluorosis area, local clay was used to mix with coal for indoor combustion. There are two key steps in the procedure of the indoor transition of fluorine: indoor wet corns and vegetables strongly absorbed fluorine from indoor air; and fluorine strongly accumulated in clay, which was mixed with coal for combustion. Therefore, with the increasing of… Show more

“…Meanwhile, based on other reports [74,[77][78][79][80][81][82][83], the main cause of the endemic fluorosis in SW China is the use of F-rich mixing clay. Fluorine pollution is controlled by the acidity of coal and SW Chinese coal has a very high acidity, which can have chemical reactions with mixing clay that produce HF gas under specific conditions, like heating or burning [84].…”

“…At present, the proportion of powder coal in China is generally up to 60 % when coal is mined mechanically. Powder coal is cheaper (only one-third of the price of a chunk of coal); thus, local residents usually buy powder coal for domestic use (Zhang and Cui 2004;Zheng et al 2007). When powder coal is directly placed into a stove, the fire is extinguished because of the absence of oxygen, or it can fall directly to the bottom of the stove and fail to combust.…”

“…Owing to its high viscosity, good refractoriness, and economy, clay from B Horizon of soil is favored and adopted widely as the preferred adhesive for making briquettes. The large size of briquettes can prevent the leakage and loss of powder coal, and ensures that there is more space between fuel pieces, thereby yielding higher combustion efficiency (Chen et al 2004;Wu et al 2004;Zheng et al 2007). …”

“…For decades, a wide mountainous area of Qinling-Dabashan cordillera in Southern Shaanxi Province, northwest China, was known as one of the major Xuorosis endemic areas due to the indoor burning of high Xuorine-content solid mineral fuel (Zheng et al 2007). Over the years, more and more arseniasis cases have been diagnosed among the primarily diagnosed Xuorosis patients in this endemic area.…”
