“…The physicochemical properties analyzed (Tables 1, 2), in general, fall into the range of values comparable to what has been found in other cities of the world where pH, C оrg content and EC varied between 7-9, 1-17%, and 100-2800 μS/cm, respectively (Wang and Qin 2007;Al-Khashman 2007;Ladonin and Plyaskina 2009;Acosta et al 2011;Yisa et al 2011;Hu et al 2011;Sutherland et al 2012).…”

“…Moscow has numerous industrial enterprises, heating power plants (HPPs), an extensive road and transport network, and over 4.6 million cars. Similar but limited in scope studies were previously conducted only for individual districts of Moscow (Ladonin and Plyaskina 2009;Vlasov et al 2015;Prokofieva et al 2015;Bityukova et al 2016;Ladonin 2016). The purpose of this study was to evaluate the main physicochemical properties and the accumulation potential of the Moscow's road dust with respect to pollutants as its chemical composition is one of the important indicators of urban environment quality.…”

“…Road dust is a multicomponent substance formed as a result of washing out and deflation of roadside soils, wear of different components of transport infrastructure and vehicles, crushing of solid waste and residues of de-icing agents (DIAs), and atmospheric precipitation of particulate matter (Ladonin and Plyaskina 2009;Nazzal et al 2013;Prokofieva et al 2015). Road dust originates from various sources and indicates pollution level of urban landscapes, since its particles are the carriers for many pollutants, including heavy metals and metalloids (HMMs).…”

Road dust is a composite substance formed due to wear of different components of transport infrastructure and motor vehicles. In 2017, 214 road dust samples were collected in Moscow to analyze pH, electrical conductivity (EC), and organic carbon (Cоrg) content that controls the ability of dust to fix pollutants. The road dust was dominated by sand and silt size particles (the share of PM10 particles varies from 2.3% to 39%) and had alkaline pH (6.4–8.1), high EC (33–712 μS/cm) and Cоrg (0.17–6.7%). The road dust is alkalinized by detergents and particles formed by abrasion of roadways and blown out from construction sites. A three-fold excess of the EC over the background values (dust in parks) is mainly due to the use of the de-icing agents and roadway maintenance. But the concentration of Cоrg in the Moscow’s road dust is on average 2 times lower compared to the background values; the increased content of Cоrg in the courtyards is associated with the application of organic fertilizers. The most significant factor that determines the physicochemical properties of the dust was the type of a road. The dust on large roads including the Third Ring Road had higher pH (7.0–8.0) and EC (98–712 μS/ cm); it contained higher proportions of the fine particle-size fractions compared to other roads. The Cоrg content in the road dust was minimum on Moscow’s major radial highways due to the insignificant contribution of soil particles. The spatial trends in variability of the physicochemical properties of the dust in Moscow were not evident as they were to a large extent masked by other factors: proximity to industrial zones and large forest parks, differences in the de-icing agents used, unequal frequencies of road cleaning, and the various contribution of soil particles that vary in composition and genesis in different parts of Moscow.

“…However, already on May 2 it increased sharply due to the anthropogenic emission of PTEs to the atmosphere from the biomass burning in suburban areas and the territory of the MSU Botanical Garden, together with the coal burning during picnics near MSU and vehicle emissions due to the large number of traffic jams that occur when residents leave the city. This is confirmed by the increase in the levels of wet deposition of K, Rb, Mn, Sn, Sb, and As these days, which are often used as indicators of controlled biomass and coal combustion or forest fires (Landing et al 2010;Samsonov et al 2012;Grivas et al 2018). Thus, the spring period is characterized by a strong influence of forest fires in the Moscow region and the biomass burning in residential areas on the composition of atmospheric particles in Moscow (Popovicheva et al 2020a), which is indicated by the high values of the black carbon (BC) to the PM 10 content ratio in the atmosphere (Popovicheva et al 2020b), since BC is a marker of biomass burning or fuel combustion.…”

“…The first geochemical association (Zn-Sb-Ni-Ca-Co-Bi-Sn-Al-W-Cr-Fe-Na-P) includes PTEs coming from anthropogenic (Zn, Sb, Bi, Ca), anthropogenic-terrigenous (W, Sn, Co, Ni, Na, P) and terrigenous (Al, Fe, Cr) sources. Sb, Zn, Sn, Bi, W, and Ni indicate the resuspension of road dust and its various grain size particles, since in Moscow and some other cities road dust is highly enriched with these PTEs (Ladonin and Plyaskina 2009;Fedotov et al 2014;Ermolin et al 2018;Kasimov et al 2019a;Ladonin and Mikhaylova 2020;Vlasov et al 2021b). 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).…”

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 article presents the results of studying the composition of road dust in Tyumen, a large city in Western Siberia. On roads with different tra c intensities, 50 dust samples were taken, in which the particle size distribution, pH, and organic carbon content were determined. The content of 62 major and trace elements was studied using atomic emission spectrometry (AES-MS) и inductively coupled plasma spectrometry (ICP-MS). It was revealed that the dust has an alkaline reaction pH = 7.4 -10.2, low organic carbon content (0.07 -2.9%). The particle size distribution is dominated by particles PM = 100-250. The content of small particles (PM <2 and PM2-10) representing the greatest environmental hazard is minimal on roads with an average tra c intensity. Studies have shown that the main road dust pollutants in Tyumen are Ni, Sb, Cr, Zn, Co. The average geoaccumulation index (Igeo) values are ranked as Ni (2.2) > Sb (1.5) > Cr (1.3) > Zn (0.4) > Co (0.4) > Cu (0.2). The contamination evaluation through enrichment factor (EF) calculation showed that road dust is highly enriched in Ni and signi cantly in Cr and Sb. More than 80% of Zn, Co, Cu and more than 90% of Ni, Sb, Cr come from anthropogenic sources. By the content of Ni and Cr, Tyumen surpasses all cities of the Earth where similar studies were carried out. The high Ni content is associated with the composition of local soils and roadways, increased content in vehicle exhaust gases, and abrasion of metal parts. Calculations of the total pollution indices (IPI and Zc) showed that the level of road dust pollution in most of Tyumen's territory is average, moderately hazardous.
