“…The average PM accumulation found at the sampling points within this subcluster was 10 mg/m 2 /day, which value was close to the background value, 7.0-10.9 mg/m 2 /day, mentioned by other authors [35,36,6]. The mean background values found in this study for Al-, F-, Cl-, and SO 4 -ions appeared to be similar to measurements made by other pollution researchers [36][37][38].…”

“…The accumulation of Cl-ions (46 mg/m 2 /season) was 1.5 times the element accumulation in snow water in Stolby Forest Reserve and much higher than central taiga of Komi Republic (21 mg/m 2 ) [37] and the Snezhnaya River basin, Baikal Region [38]. Subcluster 1.2 (the woodland park zone) encompassed popular public forest sites in the town and at the town/ forest interface, in the south-and northwestern parts of Krasnoyarsk.…”

“…Ions of SO 4 -showed an accumulation of 218 mg/m 2 /season (560 mcg/l), almost twice the background value fond for Stolby Forest Reserve (230 mcg/l), near Krasnoyarsk [4]. In the central taiga zone of Komi Republic, the background SO 4 -in snow water is 130 mg/m 2 /season [37].…”

Pollution is among key factors that determine townsmen's life quality and is seriously considered when it comes to people's residence preferences, housing cost, house building policy, migration, and other aspects of urban area management. Accurate pollution estimation and town zoning by pollution level based on these estimates are, therefore, challenges to be taken up in big cities with highly developed industries. Krasnoyarsk (56°1'8" N, 92°52'4" E), Siberia, the town of interest of this study, is, unfortunately, an infamous industrial pollution champion among Russia's largest towns.

“…Belozertseva et al (2017) studied chemical composition of snow in lake Baikal area and showed the difference between contaminating compounds for different hollows in this area: the northern part is contaminated mostly by SO 4 2-, HCO 3 -, Cl -, Ca 2+ , while the southern receives NO 3 -, NH 4 + and Na + . Analysis of the chemical composition of snow cover in Komi (Vasilevich et al 2011) showed low salinity and acid pH values -EC varies from 9.4 to 10.02 µS/cm that is approximately 6.0 −6.4 mg/L, pH varies from 4.6 to 4.8. and studied the snow cover of Voronezh in 2013 and 2014. The authors have shown that nitrates, nitrites, and chlorides predominate in technogenic emissions in Voronezh, and that motor transport and industrial enterprises are the main sources of pollution.…”

This article summarizes the data of the chemical composition and the acidity of the seasonal snow precipitation for the cold periods 1999-2006 (n=180), 2010-2013 (n=82) and 2018-2019 (n=18) in different parts of Moscow. Major ions content was measured, such as SO42-, НСO3-, Cl-, NO3-, Са2+, Mg2+, Na+, K+ and NH4+, also pH and sum of ions (mg/L) were measured. During the 2018-2019 season, snowpack samples were taken twice at 4 sites in Moscow: two in the North-East Administrative Okrug (NEAO) near the road and in the park at the distance of 3 km from each other, and two in the South- Western Administrative Okrug (SWAO) and in the Western Administrative Okrug (WAO) near the road and in the park at the distance of 6 km from each other. Samples were taken with a break of 5 days to determine the dynamics of the chemical composition within the beginning of the snow-melting. In each pair of sampling sites there was one that is located in the park and one located near the road. This experiment showed a slight variability of the chemical composition of snow during 5 days under the influence of the new snowfall. In general, there is a trend of changing the composition of snow from calcium carbonate to calcium chloride, which is mainly connected to the use of anti-icing reagents; for the same reason, the areas that are closer to the roads are the most polluted.

Снежный покров играет фундаментальную роль в наземных экосистемах, поскольку влияет на количество и качество воды, глобальные биогеохимические циклы и свойства почвы. Состав снежного покрова является одним из факторов, воздействующих на гидрохимический режим территории. Формирование химического состава снежного покрова в российской Арктике происходит под влиянием естественных и антропогенных факторов, их соотношение зависит от расстояния от крупных промышленных центров и особенностей формирования гидрометеорологического режима территорий и акваторий. Целью исследования являлась количественная оценка степени влияния естественных и антропогенных факторов на состав снежного покрова Арктической зоны Российской Федерации (АЗРФ). В работе выделено 14 факторов формирования состава снежного покрова в Арктике: состав атмосферных осадков, сухое осаждение, загрязнение атмосферного воздуха, количество оттепелей, продолжительность залегания снежного покрова, метеорологический потенциал загрязнения, циркуляция атмосферы, морской аэрозоль, дальний перенос, ветровой режим, количество и режим осадков, влагозапас, рельеф (открытость местности, экспозиция склонов), местные антропогенные источники поступления поллютантов. Выделение факторов проводилось автором в процессе изучения процесса формирования состава снежного покрова, в том числе обзора литературных источников. Оценка степени влияния различных факторов на состав снежного покрова АЗРФ проведена с помощью метода экспертных опросов и метода анализа иерархий. По результатам обработки данных проведенного экспертного опроса наибольшее влияние на формирование химического состава снежного покрова в российской Арктике оказывают местные антропогенные источники поступления поллютантов и состав атмосферных осадков. Наименьший вклад оказывают дальний перенос и ветровой режим.
