Mobile Measurement of PM<sub>2.5</sub> Based on an Individual in Ulaanbaatar City
In the present study, we measured fine particulate matter (PM<sub>2.5</sub>) on the daily route of our study participant in order to determine her exposure and dose of PM<sub>2.5</sub> in every microenvironment (ME). The measuring instrument, created by Nagoya University and...
