Objectives: Residents of ger in Ulaanbaatar used substantial amount of coals at winter. Indoor coal combustion caused higher indoor and outdoor PM<SUB>2.5</SUB> concentration. However, other indoor activities affecting indoor PM<SUB>2.5</SUB> concentration had not been found. The aim of this study was to define important indoor factors affecting indoor PM<SUB>2.5</SUB> concentration in ger.
Methods: We measured PM<SUB>2.5</SUB> concentration and observed indoor activities in ger. Two models were applied to find important indoor factors affecting PM<SUB>2.5</SUB> concentration. First, multiple linear regression was used to detect significant factors. Second, linear mixed model was conducted in order to adjust difference of monitor and date.
Results: Outside PM<SUB>2.5</SUB> concentration, adding fuel, indoor smoking, and ventilation were significant factors affecting indoor PM<SUB>2.5</SUB> concentration. In addition to the factors, cooking was found to be an important factor when difference of monitors and date were included.
Conclusion: Residents of ger were exposed to higher indoor PM<SUB>2.5</SUB> concentration. This study identified indoor activity affecting PM<SUB>2.5</SUB> concentration. This result can be used as a basic information for indoor air quality improvement in ger.
