Coal-fired Power Plant Emissions Of Particulate Matter Air Pollution Monitoring And Hazard Studies

Inhalable particles(IP) are one of the chief air ollutants in China. It badly effects on human health, especially those whose aerodynamic equivalent diameter are less than 2.5μrn.Among the inhalable particles, Coal-fired power plant as the first pollutant source plays an important role in emitting the PM10 and PM2.5. Therefore Coal-fired power plant emitted inhalable particles are draw much attention in recent years.China is the largest coal produce country in the world. More than 70 percent of energy comes from coal, and more than 96 percent of thermal power plant are using coal, and the total volume of emitting soot reaches to 289.73 x10~4 tons. Thus the air polluted cities are increasing year by year.This paper chooses the Beijing City as a representation of air polluted city to moniter the concentration of PM10 and PM2.5 emitted from coal-fired power plant during winter senson. Data obtained and other results such as forming mechanism,volution process as well as physical and chemical properties are analysed.The air pollutants from coal-fired power plant do harm to downwind residents. The dissertation has Jiaozuo City as a case, the data on respiratory tract disease are surveyed and analyzed, and some studies about PM toxicology and epidemiology are summarized.
