“…A significant threat posed by the aeolian dispersion of contaminated dust particles from mining waste heaps is indicated in Sharyn Gol (Fig. 3C) and mentioned as risky in other related studies 7,57,59 . Park et al 60 even stated that all waste soil samples from Baganuur appeared to have desertification potential.…”

As Mongolia is considered one of the most resource extraction-dependent countries globally, significant mining-related environmental and human health risks are expected. The aim of this study was to (I) assess the impacts of mining on soil pollution with metals in Mongolia's key coal mining towns (Baganuur, Nalaikh and Sharyn Gol) and (II) review the current knowledge on soil pollution with metal(loid)s and related health risks in Mongolia. The results showed predominantly low soil contents of Cd, Cu, Pb and Zn and a related absence of severe pollution and potential health risk in the coal mining towns. Urban design, rather than the presence of mines, controlled the pollution distribution. Despite the methodological shortcomings of several studies on soil pollution in Mongolia, their results suggest a similarly low threat in the three largest cities (Ulaanbaatar, Darkhan, Erdenet) and several mining areas. While the generally highlighted risk of As seems like an artificially escalated issue, the content of Cr in urban soil may be a neglected threat. Further pollution research in Mongolia should focus on street dust and drinking water pollution.

“…The spatial distributions of the soil pH show acid conditions (3.0-5.0) in the vicinity of the tailings pond, open-pit and industrial area of Erdenet, and the higher hills, ger area and the area below the open-pit mine in Baganuur. A previous study in Erdenet by Kosheleva et al (2017) found that more acid soils were found in areas closer to the mining sites and anthropogenic areas. Recent literature describes soil pH ranges of 5.6-7.1 for Baganuur (Park et al, 2020) and 5.2-6.3 for Erdenet (Kosheleva et al, 2017), but it is important to note that these studies covered different areas as compared with the investigation presented here.…”

Soil contamination and the resulting ecological disturbances are a common phenomenon in mining areas, including the vicinities of the largest and oldest open‐pit mining areas in Mongolia. In this work, the potential ecological risk index (RI), Nemerow integrated pollution index (PIN), and Geoaccumulation index (Igeo) were used to estimate the level of soil contamination with Ni, Cu, Zn, As, Cr, and Pb in the top layer of the soils around Baganuur coal mine and Erdenet copper–molybdenum mine. Three different analytical methods were used: portable X‐ray fluorescence (pXRF) for the first assessment of samples, and stationary X‐ray fluorescence and Inductively Coupled Plasma Optical Emission Spectroscopy for the confirmation of results in the laboratory. Even though general contamination levels in both study areas were relatively low, some potentially toxic elements were found at contents several times higher than the maximum permissible level (MPL) according to the national standard of Mongolia. In the Baganuur area, Zn was up to 2.8 and As was up to 3.00 times higher, while in the Erdenet area, As was up to 2.4, Cr was up to 1.7, Cu was up to 8.1, and Zn was up to 1.2 times higher than MPL of the national standard in the vicinity to the mining and industrial area. The estimation of the pXRF measurement had generally similar results to the other two laboratory methods based on spatial distributions of heavy metal content. Among the different geochemical indices, the PIN showed a more accurately distinguished spatial distribution of contamination. For example, highly contaminated areas were found in the vicinity of the open pit, the tailings pond and the industrial area based on PIN results: 3.6%–4.9% of the total area in Baganuur and 3.1%–4.9% of the total area in Erdenet. The identified pollution levels emphasize the essential need for soil rehabilitation in mining areas, a key factor for Mongolia's economic development and environmental stability. In addition, the lack of documented soil rehabilitation initiatives underscores the pressing need for enhanced environmental responsibility in the country's expanding mining sector.

“…Great concentration of the studied metals, in the drainage water, after irrigation of plants was observed. Kosheleva et al (2017) investigated the conditions of the lateral migration of potentially toxic elements and identified the zones of their accumulation in soil catenas of ore mining landscapes in the cities of Zakamensk (Buryat Republic, Russia) and Erdenet (Mongolia) which are situated in the basin of the Selenga River. The authors used the catenary approach and the concept of lateral geochemical barriers and found an increased content of sand with W, Mo, Cd, Bi, Pb, and Sr derived from the tailings by water erosion in Zakamensk and of silt particles windblown with V, Co, Sr, and As in Erdenet.…”
