TEST Nalaikh is an old coal mining city with a population of 35,000 and it is one of the remote districts of the city of Ulaanbaatar. The Ulaanbaatar city government is going to move building material industries to this district and establish other industries in Nalaikh in order to reduce air pollution in Ulaanbaatar. The purpose of this project is to establish a baseline of PM2.5 air pollution and assess possible industrial sites in the city. The German-Mongolian Institute for Resources and Technology (GMIT) is the only post-secondary institution in Nalaikh and the only organization helping the Nalaikh district government on environmental pollution management.  GMIT is going to assess the air pollution situation in Nalaikh, help to identify industrial sites in Nalaikh and help in the environmental management of the district. Establishing the baseline of PM pollution is an important measure for future management of pollution. As part of this project, specialists from GMIT will measure PM2.5 for around 2 years, assess the impact of existing Heat Only Boiler (HOB) for heating the city’s organizations and apartments as an example, assess the PM2.5 situation and identify possible industrial sites based on PM measurement and GMIT weather station measurements.  


PM2.5 will be studied as it is very harmful to human health and the PM2.5 levels exceed air pollution standards among the other pollutants based on preliminary measurements. Nalaikh district is one of the remote districts of the city of Ulaanbaatar, and the district has no PM monitoring program, and no study of air pollution was done before. But establishing a baseline study is required as the district has been designated to become an industrial district. PM2.5 will be measured year-round during the project period and sustainable measurements will be continued into the future. Daily, monthly, yearly time series of PM2.5 pollution will be built and the impact of pollution sources will be assessed on the time series and according to weather data, especially according to wind direction and speed. The transfer of Ulaanbaatar pollution to Nalaikh and the influence of Heat Only Boiler in the Nalaikh district will be studied. This research will benefit the Nalaikh district government as baseline research to assess the air pollution situation of the district. Furthermore, guidelines and recommendations will be made to help select possible industrial sites, as Ulaanbaatar has designated this district as a future industrial district.


The overall objective of this project is to help city government to establish air pollution control. The objectives are to establish a baseline of PM pollution for future control of environmental pollution in the city, to select industrial sites so as not to increase pollution in the city. As an old coal mining city and people get coal themselves or purchase it cheaply, smoke pollution dominates the city in the cold season. After a baseline of PM2.5 pollution has been developed, the city government will seek ways to reduce it, maybe by introducing improved and lower emission stoves, more use of electric heating and so on.The city government will be advised on the selection of industrial sites by means of the impact of pollution from industry. It is important to start monitoring air pollution before some factories are established. The establishment of a PM pollution baseline, measuring PM2.5 pollution for around 2 years. Yearly, monthly daily time series of PM2.5 will be determined and compared with international and Mongolian standards. The determination of the influence of weather conditions on air pollution will be conducted.

Expected results

  • PM2.5 air pollution yearly, monthly and daily time series will be determined for Nalaikh based on 2 years’ data
  • Influence of Ulaanbaatar city pollution on Nalaikh and on the site will be assessed
  • Weather reports of weather will be developed and parameters (T,P,RH,WS,WD, SR, Pr) will be determined
  • Air pollution baseline of Nalaikh district,  inter-correlations of PM2.5 and weather parameters will be determined
  • Comparison of the clean village and polluted central Nalaikh will be shown as an example
  • - Elemental composition of air samples will be determined based on XRF analysis, the presence of heavy toxic elements in the air will be assessed
  • PM2.5 pollution impact of Heat Only boiler of Nalaikh district to the site will be assessed
  • Industrial sites in Nalaikh district by means of air pollution will be identified
  • 3 students will be trained in the measurement and data processing of air pollution measurements
  • Results of the study will be introduced to the local government, a seminar on the result will be organized
