The paper is devoted to the investigation of Ulan Bator air pollution and the sources
of this pollution. The main reasons are geographical location of the city, unique natural and
climatic characteristics, and mistakes in town building. Pollution is also caused by economic
reasons. During the cold season, air circulation decreases leading to an inverse temperature
occurrence and, as a result of this inversion, the polluting waste particles scatter in the air.Other factors contributing to Ulan Bator air pollution include destruction of vegetation in
Ulan Bator suburbs, lack of green areas in the city, bad infrastructure development, bad
quality of oil products, etc. In Ulan Bator, annual average particulate matter concentrations
(PM10, i. e. particles that cause damage in the lungs when inhaled) have been recorded at as
high as 279. The World Health Organization’s recommended PM10 level is 20.
