“…1). Nornickel metallurgical plant where Ni is smelted is one of the main sources of heavy metals in the Arctic ecosystems (AMAP 2005;Zhulidov et al 2011;Onuchin et al 2014;Lezhenin et al 2016). But if we judge by the prevailing air mass transfer trajectories, its influence must be weak in the vicinities of Nadym.…”

The article presents the results of a study of snow composition in the town of Nadym (Western Siberia) During the studies conducted in 2021–2022, we determined dust load, concentrations and ratio of dissolved and suspended forms of metals and metalloids (MMs). In the background area, the snow composition depends on the long-range transport of pollutants. We analyzed air mass trajectories using the HYSPLIT model, and the analysis showed the industrial regions of the southern Urals, southeastern Siberia, and Kazakhstan to be the sources of MMs. The content of the insoluble fraction increases 23 times in the town. The dust load in Nadym is higher than in the urban communities situated in the temperate climate zone, although the town is smaller in population and has no large industrial enterprises. A significant increase in the dust load in the town leads to a ten- and hundredfold increase in the content of many MMs. Local soils (Fe, Al), vehicles (W), building dust (Mg, Ca), and anti-icing agents (Na) are the sources of pollution. We showcase that the high dust load is caused by meteorological factors which reduces the dispersion of pollution, such as temperature inversions and a large number of calm days. The case of Nadym demonstrates that winter air quality in polar settlements can be worse than in urban areas in the temperate zone even with few pollution sources. The trend towards an increase in the number of windless days, observed in Siberia as a result of global climate change, increases the risk of anthropogenic pollution of the atmosphere of polar cities.

“…Of course, such large-scale mining does not only have an impact on water quality, as the Russian Federal Statistics Service notes that Norilsk is the most polluted city in the country, 5 Calculations done on data from the Hartwell and Coursey (2015) database. with high concentrations of sulfur dioxide and heavy metals in the air along with rivers which occasionally run red (Korets et al 2014;Lezhenin et al 2016).…”

While there is a sizeable body of evidence linking greater economic freedom to better environmental outcomes, one of the outliers which persists is the ambiguous relationship of trade to the environment. Some theoretical approaches posit that trade would lead to a "race to the bottom," where firms would move to countries with the laxest regulations; on the other hand, the competitive effects of trade should force polluting firms to clean up in order to better serve their customers. But what occurs when trade expands among countries who already have shown -via policy and politics -that the environment is not a priority? Such an example comes from real life with the Eurasian Economic Union (EaEU), a collection of autocracies who have pursued integration but without any extensive, market-based liberalization. This paper examines the role of the EaEU in increasing trade among its member states and attempts to ascertain the effect this has had on the already-fragile environments in each of these countries. A theoretical examination, backed up with an empirical exercise, shows that the EaEU did indeed lead to more environmentally unfriendly production. I conclude that the EaEU needs to shift towards marketbased liberalization in order to improve environmental quality within the group.
