“…A standard soil sample (SDPS-3) with a mercury concentration of 290±58 ng/g was used as a standard reference material. A number of papers have been published in which the mercury content in snow samples was determined using atomic absorption spectrometry (Filimonenko et al 2014;Grebenshchikova et al 2017;Gustaytis et al 2018;Talovskaya et al 2019).…”

Studies on thermal power plant areas with respect to chemical composition of particulate matter deposited in snow cover are limited. This study aims to monitor (2014–2022) particulate load and trace elements associated with the particulate matter distributed around (0.5-4.5 km) the coal-fired thermal power plant in Karaganda. In this study, snow cover was used as an effective scavenger of atmospheric pollutants. Using instrumental neutron activation analysis and atomic absorption spectrometry, the content of 26 elements and Hg, respectively, was determined in the particulate phase of snow. The results showed that particulate load varied from 26 to 1751, with mean of 427 and a background of 47 mg m-2 d-1. Anthropogenic impact caused a significant increase in content of U, Hg, Ta, Zn, Na, Cr, Co, Sr, Rb, Cs, Sc, Ca, Fe, Nd, Ba (2–30 times) in the samples compared to the background. Metal-bearing phases of Zn, Ba, As, U-Ta-Nb were detected through scanning electron microscope. The highest levels of particulate load (169–1032 mg m-2 d-1) and element contents in the samples were localized up to 0.7 km from the thermal power plant. The changes of particulate load and element composition of snow deposits during the monitoring period were connected with temperature, modernization of dust-collecting equipment, composition of coal and fly ash, long-range transport of emissions from other industries. The element content and metal-bearing phases in the particulate phase of snow can be used as markers for identifying emission sources from coal combustion.

“…Sampling was carried out using the pit method (Talovskaya et al, 2019;Yanchenko, 2020). A block in the form of a rectangular parallelepiped was cut out in the snow to the full depth, except for the lower 2-3 cm, so that the samples would not be contaminated with soil.…”

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.

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 traffic. No emissions of PAHs from oil spills from the nearby Samotlor oil field have been identified. It is concluded that the hydrocarbon pollution of the atmosphere from the field weakens during the winter period compared to the warm season. Application of the Igeo index characterizes the majority of the studied samples as unpolluted, 24% of the observation sites are classified as moderately polluted, and one (4%), as highly polluted.
