英文摘要	From December, 2012to April, 2013, measurements of personal exposure levels to atmospheric fine particulate matter (PM2.5) in Beijing were conducted using laser dust monitor (Model LD6S) with the method of daily tracking for single participant, and the different participants' time-activity journals were also collected to calculate the daily averaged exposure levels and merge application. During the monitoring period, the ambient PM2.5 concentrations issued by the Beijing Municipal Environmental Monitoring Centre were recorded synchronously. The local mean concentrations of PM2.5 in winter and in spring were 127 ??g/m3 and 69 ??g/m3, respectively, and the former was much higher than the latter. The median value of personal daily exposure level was 54 ??g/m3 and the averaged ratio to the ambient PM2.5 concentration was 0.60. The averaged indoor exposure fraction reached 80% of the total exposure, and the outdoor exposure and the traffic exposure separately accounted for about 10%. There was no significant difference between the exposure levels of different populations and different seasons. As the ambient PM2.5 concentration exceeded 75 ??g/m3, a significant correlation existed between the ambient PM2.5 concentration and the PM2.5 concentrations in different microenvironments, including residential house, office, restaurant, bus and street.; EI; 0; 3; 774-779; 34
