“…In the last two decades, with worsening air quality in Ulaanbaatar, interest in addressing air pollution has been increased. A number of research works has been performed on the assessment of the ambient air quality by evaluating criteria (Luvsan et al, 2012;Huang et al, 2013) and trace (Byambaa et al, 2019;Nirmalkar et al, 2020) pollutants in Mongolia, chemical (Jung et al, 2010;Davy et al, 2011;Nishikawa et al, 2011;Batmunkh et al, 2013;Amgalan et al, 2016) and physical characteristics (Jung et al, 2011;Oyungerel et al, 2012;Hasenkopf et al, 2016) of atmospheric particulate matter, source apportionment of certain atmospheric pollutants (Davy et al, 2011;Nishikawa et al, 2011;Amgalan et al, 2016) and other climatic and socioeconomic factors impacting urban air quality (Luvsan et al, 2012;Ganbat et al, 2013;Huang et al, 2013;Ganbat and Baik, 2016). To date, there have been no systematic reviews of published studies on air pollution in Mongolia.…”

“…The size distribution of the nanosized fraction of ambient air particulate matter along the roadside was investigated by Oyungerel et al (2012). Snow samples collected from twelve locations of the city were used for particle size and size distribution analysis by photon crosscorrelation spectroscopy.…”

“…were found in the range of 74-100 nm, while 83.73% fine particles (PM2.5) were found in the range of 100 nm−2.4 μm, and 16.25% coarse particles (PM10) were found in the range of 2.4−4.0 μm. Aerosols along the road had a high content of PM2.5 particles (Oyungerel et al, 2012). Hasenkopf et al (2016) studied the particle sizes, shapes, and ice-nucleating properties of particulate matter collected during different seasons.…”

For the last decades, Mongolia has seen an extensive escalation in population growth, urbanization, and industrialization, together with great increase in mining and usage of vehicles. As a result, a substantial increase has taken place in the types and number of emission sources of air pollutants, especially in urban areas. During the cold season, air pollution level in Ulaanbaatar, the capital of Mongolia, is frequently ranked as the highest in the world. However, due to the lack of air quality management, the country is suffering from a deterioration of air quality.Despite the worse air pollution situation, due to insufficient research capacity of the country, to date, research works on characteristics of air pollution have mainly been based on current capability and/or collaboration with foreign institutes. The research gap in this area necessitates numerous investigations, which could have great importance in developing mitigating strategies and minimizing the adverse impact of air pollution on local and regional scales. This paper reviews previously available studies and reports in international scientific journals on air quality in Mongolia. Based on the existing research works, future needs of studies on ambient air pollution in Mongolia are suggested.

The synthesis of silver nanoparticles loaded on the activated carbon (AC) surface were performed under SCW condition at 673 K and 31.15 MPa in a batch reactor. In supercritical region, fine particles are rapidly synthesized due to reaction rate increase at low dielectric constant of supercritical water. Samples were prepared with different concentrations of silver acetate solution and various reaction times. The synthesized silver loaded on AC particles were characterized by the Fourier transform infrared spectroscopy (FTIR),X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). FTIR spectrum of primary activated carbon, activated carbon treated under supercritical water condition and synthesized AC-Ag was compared. The particles size and crystallite size of silver deposited on AC surface were analyzed by TEM and XRD, respectively.
