Abstract: In the present study, we measured fine particulate matter (PM 2.5 ) on the daily route of our study participant in order to determine her exposure and dose of PM 2.5 in every microenvironment (ME). The measuring instrument, created by Nagoya University and Panasonic Corporation, Japan, was carried close to the breathing zone most of the time. Each data point was collected for 10–30 s or 2–6 cycles/min for 24 h from 1 October 2018 to 30 December 2018. Public transportation showed the highest level of PM 2.5 compared with other MEs, including residence apartments, houses (ger district), the National University of Mongolia (NUM), food courts or restaurants, and other indoor locations. The personal daily average exposure to PM 2.5 was 35 µg/m 3 on 4 November 2018; on the other hand, this value was evaluated as the highest level of exposure compared to other measurement days. Interestingly, the study participant‘s exposure and dose of PM 2.5 was lower than those stated in the World Health Organization (WHO) air quality guidelines, with 25 µg/m 3 from 4:00 to 7:00.
