“…This indicates the significant role of wet deposition processes for the PTEs input into terrestrial landscapes. The main sources of most of these PTEs are vehicle emissions, fuel combustion, tires and brake pads wear, road surface abrasion, roadside soil particles blowing, industrial enterprises emissions, as well as macroregional long-distance transport of pollutants (Demetriades and Birke 2015;Grigoratos and Martini 2015;Grivas et al 2018;Konstantinova et al 2020;Liyandeniya et al 2020;Logiewa et al 2020;Orlović-Leko et al 2020;Ramírez et al 2020;Seleznev et al 2020;Tian et al 2020), which is confirmed by the previously identified sources of snow cover pollution in the western part of Moscow (Vlasov et al 2020). The remaining PTEs on the territory of the MO MSU were apparently of mixed anthropogenic-terrigenous sources (P 38 , Ba 31 , As 30 , W 22 , Mn 20 , Sn 19 , Na 16 , Co 14 , Ni 12 , Be 11 , K 11 ) and terrigenous origin (Rb 6 , Cr 4 , Fe 3 ), which indicates the influence of solid particles blown out from the Earth's surface and included in the atmospheric precipitation.…”

“…For example, in the eastern part of Moscow, the fine fraction PM 1 and the coarser PM 1-10 of road dust are significantly (EF > 5) enriched in Sb, W, Sn, Cd, Zn, Cu, Pb, Mo, and Bi, especially on Moscow Ring Road and highways (Vlasov et al 2015;Kasimov et al 2020). Al, Fe, and Na are emitted by blowing out particles of contaminated urban soils (Morera-Gómez et al 2020). This source is somewhat less significant for W, which is presented in the surface horizons of Moscow soils (Kosheleva et al 2018).…”

“…carcinogenic As, Cd, Pb, Cr, Be, Ni, and Co, as well as causing general toxic damage to the body or individual organs and systems Sb, Zn, Cu, Mo, W, Sn, Se, Ba, Mn, and others (R 2.1.10.1920-04 2004; U.S. EPA 2020). Atmospheric precipitation is the most important factor in the self-purification of atmospheric air during the warm season (Ouyang et al 2019;Long et al 2020;Orlović-Leko et al 2020). Wet deposition compared to dry one is more efficient in removing PTEs from the atmosphere and causes higher pollutants input into terrestrial or aquatic systems (Ouyang et al 2015).…”

For the first time, the wet deposition and washout rates of soluble forms of potentially toxic elements (PTEs) were estimated in rains during the spring AeroRadCity experiment in Moscow. Rains are an important factor in reducing atmospheric pollution with PTEs in Moscow. Due to the resuspension of contaminated particles of road dust and urban soils, industrial and traffic impact, waste and biomass burning, rainwater is highly enriched in Sb, Pb, Se, Cd, and S, and less enriched in P, Ba, As, W, Mn, Sn, Na, Co, Ni, and Be. Significant wet deposition (μg/m2 per event) and washout rates (μg/m2 per hour) of PTEs were revealed during the public holidays in May which corresponded to the elevated aerosol content due to predominant air advection from southern and south-western regions in this period. During continuous rains, the level of PTEs wet deposition sharply decreases on the second and subsequent days due to the active below-cloud washout of aerosols during the initial precipitation events. We show that the length of the dry period and aerosol content before the onset of rain determines the amount of solid particles in rainwater, which leads to an increase in rainwater pH, and strongly affects wet deposition and washout rates of PTEs of mainly anthropogenic origin (W, Zn, Bi, Cd, Sb, Ni, B, S, K, and Cu). At the same time rainfall intensity contributes to an increase in wet deposition and washout rates of Se, As, B, Cu, Sb, S, Cd, Ba, Rb, and K. The obtained results provide a better understanding of atmospheric deposition processes and can be useful in assessing the urban environmental quality.

The assumption is supported by the results of studies in which Ba, Zn, Sb, Sn, Mo, Bi, Cr, and Ni were proved to be indicator elements for such effects of motor vehicles [91,93,118,120,[126][127][128][129][130]. Ba and Sb sulphates used as a friction modifier in the production of brake linings [131], as well as antimony sulfide (III)-Sb 2 S 3 , which is a component of brake lubricant [92] could be sources of sulfate ion in snow cover.…”

“…Input of a large group of MMs as a result of blowing and splashing mud material from the surface of roads is indicated by the formation of associations of suspended Ni-Al-Mg-Ti-Ca-Sr-Mn-Co-W-K-Rb-Ba-Ni-Fe-V and dissolved Ti-Fe-Pb-Al-Sn-Bi-W. Thus, Al, Ti, Fe, Mn, Rb, and K come predominantly with soil particles upon blowing [118][119][120]; Na, Ca, Mg, and Sr-with construction dust and large DISs particles; W, Sn, Bi, Co, Ni, Ba, Pb, and Ti-with various size fractions of road dust [67,95,119,[121][122][123][124][125].…”

Dissolved and Suspended Forms of Metals and Metalloids in Snow Cover of Megacity: Partitioning and Deposition Rates in Western Moscow

et al. 2020

Concentrations and ratio of dissolved and suspended forms of metals and metalloids (MMs) in snow cover and their deposition rates from the atmosphere in the western part of Moscow were studied. Forms of MMs were separated using a filter with pore diameter of 0.45 μm; their concentrations were measured by ICP-MS and ICP-AES methods. Anthropogenic impact in Moscow caused a significant increase in dust load (2–7 times), concentration of solid particles in snow cover (2–5 times), and mineralization of snow meltwater (5–18 times) compared to the background level. Urban snow contains Sn, Ti, Bi, Al, W, Fe, Pb, V, Cr, Rb, Mo, Mn, As, Co, Cu, Ba, Sb, Mg mainly in suspended form, and Ca and Na in dissolved form. The role of suspended MMs in the city significantly increases compared to the background region due to high dust load, usage of de-icing salts, and the change of acidic background conditions to alkaline ones. Anthropogenic emissions are the main sources of suspended Ca, W, Co, V, Sr, Ti, Mg, Na, Mo, Zn, Fe, Sb, and Cu in the snow cover of traffic zone. These elements’ concentrations in roadside snow cover exceed the background values more than 25 times. The highest concentrations and deposition rates of MMs in the snow of Moscow are localized near the large and medium roads.

Potentially toxic element (PTE) pollution in farmland soil is a global problem. It is vital to clarify the contributions of farmland soil PTE from different sources to potential ecological risk (PER) and human health risks (HHR), but the existing research methods were incomplete. This study explored a comprehensive scheme that combined source contribution and risk assessment to quantitatively assess PER, HHR and the priority pollution sources. enrichment factor (EF) and pollution load index (PLI) were utilized to estimate the features of enrichment and contamination of PTE in farmland soil. Furthermore, spatial distribution characteristics of PTE and positive matrix factorization (PMF) were combined to distinguish and ascertain the sources of PTE, and the PER and HHR model based on PMF were applied to evaluate the ecological and human health risks in different sources. Taking Puning District as an example, four sources of farmland soil PTE were quantitatively allocated. For ecological risk, the study area was at moderate ecological hazard, with industrial activities (53.67%) contributing the most. The mean of Hg was 69.82, reaching medium ecological risk. For human health risks, both adults and children had no non-carcinogenic risk in the study area, and the natural source was the greatest contributor, followed by agricultural activities. The total carcinogenic risk index (TCRI) values for adults and children were 1.40E-05 and 2.75E-05, respectively, showing no significant carcinogenic risk. Furthermore, compared with adults, the health risks of children, whether noncarcinogenic or carcinogenic, were higher than those of adults.
