“…The grain size distribution in the airborne dust suggests that grains >50 μm could be suspended when the wind is strong (Qiang et al., 2007). Moreover, particles of 10–250 μm are dominant and account for approximately 70% of the total mass in an airborne settled dust sample from Mongolia (Batbold et al., 2021) (Figure 2b). The grain size distribution of aeolian sediments situated on glacial moraines, fluvial terrace floodplains, or mountain slopes in western Mongolia shows a main peak at 63–630 μm basically (Klinge et al., 2017).…”

The history and driving forces of aeolian activity in western Mongolia remain poorly understood due to the scarcity of geological archives. Here, we obtained a record of sediment grain size from Tolbo Lake in western Mongolia to reconstruct changes in aeolian activity since ∼14 ka. The results suggest that intensified aeolian activity in the late Holocene may mainly have been a response to stronger surface winds resulting from an increase in spring insolation and mountain snow. The stable weak aeolian activity appears to coincide with ice‐rafting events in the North Atlantic during the middle Holocene and may be a response to warming at northern high latitudes, increased humidity and vegetation coverage in western Mongolia, indicating that dust from western Mongolia would possibly contribute minimally to dust deposition in Greenland during this period. This study will help understand the atmospheric dust emissions and transport processes in the earth system.

“…The elements from natural sources (Al, Ba, Ca, Mg, Na, and Si) exhibited a less proportionate increase during winter than in summer compared to the elements emitted from anthropogenic sources. The concentrations of natural source elements in PM 2.5 might be attributed to re-suspension of road dust, uplift of mineral dust from soil, dust blown from construction and demolition activities, and agricultural work on the fields influenced by the wind in the atmosphere (Habil et al, 2013;Batbold et al, 2021).…”

To examine the trends of particulate matter with aerodynamic diameter ≤2.5 µm (PM2.5) and its elemental constituents during two distinct seasons at a site away from the city center of Delhi and the National Capital Region (Delhi-NCR) of India, this unique study aimed at the development of source-receptor-effect linkages. This research paper presents results of occurrence, long-range transport (LRT), source apportionment, and human health impact assessment of 24 PM2.5-bound trace elements (Al, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, S, Se, Si, Te, Tl, Zn, and Zr). The concentration of PM2.5 during winter (296 ± 45 μg/m3) was significantly higher than in summer (114 ± 48 μg/m3) and exceeded 24 h Indian standard on most of the measurement days. The seasonal concentration ratios (winter/summer) of individual elements varied from 1.7 (Si) to 5.9 (Tl). The backward trajectory of air masses showed that transboundary transport of pollutants occurred in the downwind direction during winter, indicating that this remote site was affected by transported particulates and local activities. The principal component analysis–absolute principal component score (PCA-APCS) model confirmed five significant sources, vehicles (22.3%), soil/road dust (23.1%), coal combustion (20.9%), open burning (13.8%), and other industries (10.2%) responsible for particulate emission. The results from the multiple path particle dosimetry model (MPPD) showed higher deposition of particulates in the human respiratory system occurred during winter (44%) than in summer (40%). The elements with crustal sources of origin had a higher deposition fraction in the head region (0.27 for Si) compared to elements of anthropogenic sources (0.13 for Li). The excess lifetime carcinogenic risk (ELCR) under winter episodic events increased significantly at 128 × 10−6 compared to the summer non-episodic period at 41 × 10−6.

“…In a recent study, application of chemical methods of atmospheric dry deposited dust is used to determine the sources for the seven potentially toxic metals (As, Co, Cr, Cu, Ni, Pb, and Zn) in heating season based on settled dust analyses sampled at 57 sites in Ulaanbaatar (Batbold et al, 2021). The results showed that the metals composition in settled dust are attributed to coal combustion, vehicle exhaust emission, and soil particles.…”

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.
