“…Long-term oil production has led to widespread oil pollution (Ermolaeva 2022). Associated gas is partially ared at the eld (Pozhitkov et al 2018), which is accompanied by y ash production. Other sources of air pollution are boiler stations, motor transport, and the Nizhnevartovsk thermal power plant 10 km far from the city.…”

“…Previous studies have shown that the composition of the city's atmosphere is in uenced by nearby oil elds (Antonovich et al 2000). Recently, an increase in the concentration of dust particles in the air has been observed in Nizhnevartovsk (Pozhitkov et al 2021), and snow pollution with heavy metals, including Cd, Pb, Mn, Ni, Fe, and Zn, has been identi ed (Ivanov et al 2010;Pozhitkov et al 2018).…”

The city of Nizhnevartovsk is one of the centers of oil production in Western Siberia (Russia). A survey of the contents of trace metals and metalloids (TMMs) and polycyclic aromatic hydrocarbons (PAHs) in the snow cover was conducted there. It was aimed to study insoluble particles in the snow where the predominant share of pollutants in urban areas is concentrated. In contrast to the background areas, the deposition of TMMs in Nizhnevartovsk increases by 1-2 orders of magnitude. The deposition of Co, V, Mn, and As increases by 50-93 times, and the deposition of W increases at most (by 184 times on average). Abrasion of spikes of winter tires, abrasion of metal parts of vehicles, and combustion of motor fuels cause the pollution with W, Co, and V respectively. The total content of 12 EPA PAHs in the particulate fraction of snow in the urban area averaged 148.2 ng l -1 , and the deposition rate was 17.0 µg/m 2 . In contrast to the background areas, the share of high molecular weight 5-6-ring PAHs signi cantly increases in the city, especially dibenzo(a,h)anthracene (DahA).The indicative ratios of PAHs showed that the snowpack composition was in uenced by both petrogenic and pyrogenic sources. The proportion of pyrogenic sources is the highest in the low-rise residential area due to fuel combustion to produce heat and burning of household waste. The impact of motor transport is also major and is manifested in the maximum pollution in areas of heavy tra c. No emissions of PAHs from oil spills from the nearby Samotlor oil eld have been identi ed. It is concluded that the hydrocarbon pollution of the atmosphere from the eld weakens during the winter period compared to the warm season. Application of the I geo index characterizes the majority of the studied samples as unpolluted, 24% of the observation sites are classi ed as moderately polluted, and one (4%), as highly polluted.

“…In the large and geographically homogeneous territories of Western Siberia, which present relatively similar levels of snow deposition during the winter seasons (i.e., from 100 mm of water in the south to 140-150 mm of water in the north), particulate matter has been actively studied in industrially developed areas (for example, in Novosibirsk, Tomsk, Kemerovo, and Nizhnevartovsk) [23,[36][37][38][39][40][41][42][43]. Several studies on insoluble particles in the snowpack of relatively background areas of Western Siberia have been also conducted [16,[44][45][46][47][48][49].…”

Insoluble Particles in the Snowpack of the Ob River Basin (Western Siberia) a 2800 km Submeridional Profile

et al. 2020

Snowpack exhibits properties that make it a unique natural archive of airborne pollution. The data on insoluble particles in the Ob River catchment (Western Siberia) snowpack are limited. Insoluble particles in the snowpack of Western Siberia were studied at 36 sites on a 2800 km submeridional profile from the city of Barnaul to Salekhard in February 2020. Snow samples were collected over the full depth of the snow core, from the surface of the snow cover to the boundary with soil, except for the lower 1–2 cm. After the filtration of melted snow through a 0.45-µm membrane, the particle composition was studied using a scanning electron microscope with an energy microprobe. In the background areas, the concentration of insoluble particles in the snow was below 2 mg/L. Significantly higher particle concentrations were encountered near cities and hydrocarbon production areas. Particulate matter in snow mainly consists of biogenic and lithogenic particles mixed with anthropogenic particles (ash and black carbon aggregates). The proportion of anthropogenic particles increases near cities and areas of active hydrocarbon production.
