摘要
Abstract
One typical air pollution took place from November 18 to 25 of 2013. On the basis of meteorological conditions and air quality monitoring data analysis, single particles aerosol mass spectrometer (SPAMS) was used to analyze the causes of such pollution and characteristics of PM . The results showed that the meteorological conditions unfavorable for air diffusion were the 2.5 main cause and accumulation of low emission might be another key factor for such heavy air pollution. From the perspective of PM 2.5 composition, organic carbon proportion increased dramatically. Organic pollution was serious, and mixing of particles was intensified with the aggravation of air pollution. From the perspective of pollution source, vehicle exhaust, industrial emission and coal combustion accounted for the major proportion.关键词
