This study was conducted to compare whether the indoor air pollutants had changed in 2020 compared to 2019 in accordance with the raw coal use ban. A total 295 households and 10 family health centers were recruited from 6 districts of Sukhbaatar, Bayangol, Chingeltei, Songinokhairkhan, Khan-Uul and Bayanzurkh districts of the Ulaanbaatar city. The average 24 hours concentration of fine particles is 102.7 μg/m3 in total households, which is 2.1 times higher than the Mongolian air quality standard. The average concentration of PM2.5 which was measured in 2019, when the raw coal usage was available, is decreased by 40 percent (from 176.1 μg/m3 to 105.7 μg/m3) compared to the year of
2020 when improved fuel usage was introduced. Particulate matter pollution varied significantly by dwelling and heating types. The concentration of indoor PM2.5 was
relatively high (128.. View More»
