dc.description.abstractUlaanbaatar is one of the most polluted cities in the world, especially in wintertime. During the past two decades, several national and internationally funded projects have been put in place to reduce air pollution. One of the implemented projects is the Government of Mongolia has decided to substitute household raw coal consumption with upgraded briquette fuels in Ulaanbaatar since 2019 in order to combat air pollution. Concentrations of particulate matter (PM2.5 and PM10) in wintertime from November 2019 to February 2020 were reduced by around 40% compared previous five years, respectively. Unfortunately, there are some negative impacts, for example, an increased number of incidences of carbon monoxide (CO) poisoning along with the coal substitution. Indoor CO poisoning causes risks to people living in Mongolian gers and houses. In this study, we performed a numerical simulation of CO distribution by using the COMSOL Multiphysics. The study enables us to understand the CO distribution in Mongolian ger. The numerical simulations show, that when ger is assumed empty, the CO concentration is the largest around the stove, then becomes less from stove to crown, and is minimum near the lattice wall. In addition, CO concentration in gers and houses were recorded during the heating period. The results of this study offer important information that can be used to develop recommendations for enhancing indoor air quality in gers. By understanding the dynamics of CO distribution within traditional dwellings, strategies can be advised to improve ventilation, stove, and CO detector placements, reduce the risk of CO poisoning, and promote healthier living conditions for residents.
