Abstract
|
|
|
|
The residents of a ger, a traditional house type in Mongolia, use coal for cooking and heating. The use of unprocessed coal can adversely affect indoor air quality. In this study, the daytime indoor PM2.5 concentration in gers was measured by a real-time PM monitor, while the behavior of the residents in using a stove for heating and cooking was also observed. The indoor PM2.5 concentration was 208±173 μg/m³ (n=28). Although coal was the main fuel, the residents also used other solid fuels such as wood, plastic, rubber, and garbage. High indoor PM2.5 concentrations were observed in the morning, and the daytime temporal profile also suggested a high PM2.5 concentration at night-time. The stove and fuel types were not significantly associated with indoor PM2.5 levels. Further study is needed to determine the effect of stove type through 24 hours of indoor air quality monitoring.
