ANALYSIS OF AIR QUALITY INDICATORS: Particulate Matter (PM2.5) in Ulaanbaatar City Mongolia

Regarding the sources of air pollution in Ulaanbaatar city, 56% is caused by households, heating boilers, and coal consumption, 20% by vehicle emissions and dust, 10% by power plant coal consumption, and 14% by garbage and soil pollution. In a report issued by WHO in December 2020, it was noted that the amount of fine particle matter PM2.5, which is one of the air pollutants in Ulaanbaatar city, is 27 times higher than the permissible level. This study shows that the number of people who die from esophageal cancer increases by 70 and the number of people who die from lung cancer increases by 1 μg/m3 in Ulaanbaatar city. Also, in the calculation of the average concentration of fine particulate matter PM 2.5, it was 12-19 μg/m3 higher than the standard level in the first and fourth quarters, and 37-40 μg/m3 lower than the standard level in the second and third quarters. The results of the analysis showed that when the amount of PM 2.5 increases by 1 μg/m3, road and transport accidents increase by 705. In the city of Ulaanbaatar, when particulate matter (PM2.5) in the air, increases by 1 μg/m3, GDP tends to decrease by MNT 466,925 million, budget income by MNT 19,062.9 million, and labor force by 1,664 people. The mean absolute percentage error (MAPE)=2.3% indicates that the prediction is optimal. Effective implementation of air quality management is essential to reduce air pollution. In terms of air quality management, it is necessary to determine the goals and objectives, evaluate the situation, make an action plan for further implementation, implement it, conduct monitoring and evaluation, and use the results of the evaluation to determine the next goals and objectives and continuously improve them.
