Health Efiects of Hazardous Trace Elements from Indoor Burning of Chinese Coal
Chinas economy has developed rapidly in the last two decades so its energyconsumption and consumption emissions.Coal is a primary energy source in China and will becontinuously and widely used in the next coming years due to its relatively abundant reserves.Thisrelatively cheap coal-based energy structure is,therefore,expected to play increasingly important role in dominating the trend and level of exposure of environmental pollution in China.Toxic trace elements emitted during coal combustion are the main sources of indoor air pollution.They release into the atmosphere mainly in the forms of fine ash,smoke and flue,and thus adversely affect peoples health.These elements,especially the ones can volatilizable easily during buming also known as hazardous air pollutants(HAPs)are particularly rich in Chinese coals.Among HAPs,Arsenic,Fluorine and Selenium have already been causing severe health problems in the countryfor many years.In this study,geochemical characteristics of As,F and Se,including theirconcentrations,distributions and mode of occurrences in Chinese coal were documented.Despite ofthe presence of numerous studies indicating severe or deathly consequences of coal burning inpoorly ventilated areas,our investigations confirmed the current As and F epidemics in Guizhou(SW China)and Se epidemic in Hufei(NE China).In this study,diagnostic symptoms of arsenosis,fluorisis and selenios were also illustrated.
