Abstract
Objectives: In Mongolian housing, they use coal as a fuel for indoor heating and cooking. The combustion of coal releases particulate matter, which can affect indoor air quality. The purpose of this study was to analyze the concentrations of indoor $PM_{2.5}$ in winter time dwellings in ger town. Methods: In this study, indoor $PM_{2.5}$ concentrations, temperature and humidity in houses were measured by a real-time PM monitor, while the time activity patterns of the residents were also observed. Results: The correlation between factors that may affect the indoor air quality was analyzed.The indoor $PM_{2.5}$ concentrations were $178.4{\pm}152.7{\mu}g/m^3$ (n=37). Five types of indoor $PM_{2.5}$ concentrations have been classified, which were associated with indoor activity. The stove type, fuel types and indoor activities such as cleaning, cooking and opening the stoves were not significantly associated with indoor $PM_{2.5}$ levels. Conclusions: Further study is needed to determine the effect of stove type through 24hours of indoor air quality monitoring.
