英文摘要	Automobile source is a significant contributor to ambient particulate matter (PM), especially for PM2.5, which has become of growing public concern due to its urgency and sensitivity related to human health. A set of hourly PM2.5data from 35 monitoring stations published by Beijing Environmental Protection Bureau (BJ-EPB), covering 2 months during autumn 2013 was collected. The association between PM2.5concentrations at midnight and morning rush hours has been analyzed to estimate PM2.5concentration from automobile source. Spatial interpolation method was conducted in order to form a PM2.5distribution map of automobile source. Integrated with population data, we calculated the population exposure to automobile source PM2.5in each geographic census unit. Computational and analytical results show that the hot spots are mainly concentrated in the south and northwest of Beijing, especially near the main ring roads. ? 2015 IEEE.; EI; 3029-3032; 2015-November
