Indoor air pollution in ger, a traditional type of residence in Mongolia

Objectives: The traditional type of residence in used in Mongolia, called a ger, is an important residential form and applies coal combustion for cooking and heating. The combustion of coal in ger is the major source of indoor air pollution. The purposes of this study were to measure indoor air pollution in ger and determine the effect of cooking and heating activities. Methods: Indoor temperature, relative humidity, particulate matter less than 2.5 µm (PM 2.5 ) and black carbon (BC) were continuously measured for 24 hours in eight ger. The measurements were conducted in January or February 2015. Heavy metals in PM 2.5 filter samples were analyzed by ICP-MS. Results: Average indoor temperature and relative humidity were 19.6 ±4.6°C and 21.4±5.2%, respectively. The average indoor PM 2.5 3 . The peak concentrations of PM 2.5 and BC during cooking and heating periods were several times higher than the 24-hour average concentration. Conclusion: The major contributor to indoor PM 2.5 and BC concentrations in the ger was coal combustion for cooking and heating.
