It was critical to characterize personal exposure to PM2.5 to help prevent adverse health efects from indoor coal burning. This study compared personal exposure to PM2.5 between ger and apartment residents and evaluated the infuence of time-activity patterns. Two-day personal exposure of 16 couples from gers and 16 couples from apartments in Ulaanbaatar, Mongolia, was measured in January and February 2019. A portable monitor (ASLUNG, Rododo Science, Taipei, Taiwan) was used to measure real-time personal PM2.5 exposure, and information on participants’ time-activity patterns was recorded in a logbook. Ger residents were exposed to a signifcantly higher PM2.5 concentration (59.1(1.7) μg/m3 ) than apartment residents (26.8(2.0) μg/m3 ). However, the personal exposure of couples in gers and apartments was not afected by the time-activity pattern. The ambient PM2.5 concentration was higher than the personal PM2.5 exposure of ger and apartment residents. Daily personal PM2.5 exposure profles of all residents showed a sharp increase at 8:00 a.m. and a decrease after dawn. For all residents, the largest personal PM2.5 exposure was at home. National measures to reduce ambient PM2.5 concentrations are necessary for the reduction of personal PM2.5 exposures of Ulaanbaatar residents.
