The study on ambient air quality in the some cities of Mongolia

Abstract

In this paper presents first results of the monitoring study on ambient air quality in Ulaanbaatar and Erdenet cities of Mongolia. The work performed including sampling of particle concentration and elemental concentration valuable data. Determined for each of PM 10 and PM 2.5 sites air particulate. Research results show, that air dust concentration is mostly more than national standard level in all seasons. By this study determined that soil particles and white dust is dominant pollutant source in UB city and mining site of Erdenet.

Urban Air Quality Studies in Mongolia: Pollution Characteristics and Future Research Needs

“…Moreover, mining waste dump can have a significant contribution to ambient PM pollution in Erdenet city (Bolor-Erdene et al, 2011). Air pollution from SO2 in small cities of Mongolia is becoming worse as urbanization (Luvsan et al, 2012) and energy use increase.…”

“…Table 2 summarizes international publications focusing ambient air pollution and related topics mentioned above in Mongolia. Almost all studies conducted on the Ulaanbaatar's air pollution (Table 2), while only two works considered the air pollution in other cities (Bolor-Erdene et al, 2011;Luvsan et al, 2012). To date, ambient air quality and its related topics including chemical composition for both critical and trace (emergent) pollutants, toxicity, physical properties, source characteristics and apportionment, and distribution have been insufficiently studied (see also Fig.…”

“…Fig.2cshows December mean concentration of PM10 at three local sites -Erdenet, Darkhan, and Murun for the period of 2015-2019. As shown in Fig.2c, the PM10 concentration exceeds the national permissible level at the sites (100 µg m -3 , daily mean), with monthly average concentrations ranging between 89 µg m -3 (in Erdenet in 2015) and 230 µg m -3 (in Murun in 2019) in winter.Bolor-Erdene et al (2011) conducted an analysis of PM10 and PM2.5 mass concentrations and their elemental compositions in ambient air in the cities of Erdenet and Ulaanbaatar, but detailed information about the sampling period and concentration for the Erdenet cities was not provided(Bolor-Erdene et al, 2011).…”

“…of ambient air in many small and industrial cities of Mongolia, detailed research works on both criteria and trace pollutants -spatial and temporal variations, risk assessment, source characteristics, and socioeconomic, geographical, and climatic condition impacts -were not yet systematically investigated or published in international scientific journals. Only two works(Bolor-Erdene et al, 2011;Luvsan et al, 2012) considered a few air pollution parameters outside of the capital city Ulaanbaatar. Both studies noticed clear seasonal variations in pollution levels in ambient air at all investigated sites, with the greatest variations occurring from December…”
