Abstract:Indoor and outdoor PM2.5 were monitored simultaneously using pDR-1500monitors in typical microenvironments in Guangzhou university town from February to March, 2012, and a survey was also conducted to investigate the time-activity patterns of the university students. Potential exposure doses and exposure concentrations of PM2.5 for the students in the university town were estimated and the possible influencing factors were investigated. The potential exposure dose (DI) and daily exposure concentration of PM2.5 for the students in the university town were (882.3±241.0)μg/d and (102.8±8.0)μg/m3, respectively; the potential exposure dose of PM2.5 for the students in the university town per unit of body weight (DW) was (15.9±3.4)μg/(kg·d). PM2.5 exposure doses for the students in the university town was contributed by indoor, outdoor and traffic environments by 74.3%, 24.9% and 0.8%, respectively. The influencing factors on the DI were shown as: body weight > gender > age > exposure concentration > weekdays/weekends, while the influencing factors on the DW were shown as: exposure concentration > age > weekdays/weekends > gender. However, major was not a significant factor on the potential exposure doses of PM2.5.
