“…Analysis of the spatial distribution of R (Fig. 6a) showed that the greatest transformation of the physicochemical properties of road dust was associated with the sections of major radial highways located near the industrial zones and bus depots: in Southern districtit was the Varshavskoye Highway (electrical substations, meat processing plant, bus and trolleybus depots, factory for the production of optoelectronic devices); in Eastern district -Schelkovskoye Highway (HPP-23); in Northern district -Dmitrovskoye Highway (bus depot, mechanical plants); in North-Western district -Volokolamskoye Highway (bus depot, reinforced-concrete plant) and An increase in the pH, C оrg and the PM 10 contents in soils leads to the formation of technogenic alkaline, organo-mineral, and sorption-sedimentation geochemical barriers (Vodyanitskii 2008(Vodyanitskii , 2015, whose capacity increases with the growth of these parameters (Kosheleva et al 2015).…”

“…Dust contamination of roads increases due to wind erosion of poorly vegetated soils. Within the Moscow Ring Road (MRR), artificially created or highly transformed soils called urbanozems (Prokofieva and Stroganova 2004) dominate; they have more alkaline pH, higher levels of C оrg and readily soluble salts, increased accumulation potential and higher proportion of clay, which controls binding of HMMs in soils (Kosheleva et al 2015). Extraneous material of anthropogenic origin, e.g., construction and household waste, are common in urban soils.…”

“…When road dust settles on the surface of urban soils it changes their physicochemical properties. Road dust has a weak alkaline reaction and can form or increase the capacity of the existing alkaline geochemical barrier, which control the accumulation of many HMMs (Kosheleva et al 2015). The presence of organic matter in dust causes the formation of organo-mineral geochemical barrier, and the occurrence of various-size dust particles leads to the appearance of sorption-sedimentation geochemical barriers.…”

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.

“…When studying the urban soils with wide spatial variations of features, lower buffer capacity and fertility loss, it is important to know both the concentrations of chemical elements and the geochemical structure in order to understand the relationships between soil and underlying rocks, and also to reveal the potential pollutants (Norra et al 2006;Maurice 2009;zinkutė et al 2011;Chai et al 2015;Byambasuren et al 2018). In addition, the major element composition of soils is useful for studying the geochemical barriers, where mechanisms of trace element fixing by minerals are conditioned by sorption and oxidation-reduction processes, and by formation of new minerals-carriers (Vodyanitskii 2008; Kosheleva et al 2015). However, many studies are limited by a narrow set of trace elements despite the clayey, silty or sandy fractions affect the soil elemental composition and the trend of biogeochemical processes (Norra et al 2006;Maurice 2009;zinkutė et al 2011).…”

This article focuses on the relationships between major (Si, Al, Mg, Fe, Ca, Na, K, S, P and Ti) and potentially toxic trace (Ag, As, B, Ba, Bi, Co, Cd, Cr, Cu, F, Ge, Mo, Mn, Li, Ni, Pb, Sb, Sn, Sr, Tl, V and zn) elements in Ulaanbaatar surface soils and also sources of the trace elements in the soils distinguished by the methods of multivariate statistical analysis. Results of exploratory data analysis of 325 Ulaanbaatar soil samples show the accumulation of Ca, S, B, Bi, Cu, Mo, Pb, Sb, Sn, Sr and zn in urban soils. The major elements were grouped by cluster analysis in tree associations characterizing main soil fractions: sandy P-(K-Na-Si), clayey (Mg-Ti-Fe-Al) and silty (S-Ca). The factor analysis shows that silty fraction is enriched in major elements of both natural and anthropogenic origin. The principal component analysis from 32 variables extracted nine principal components with 82.49% of the cumulative explained variance. The results of cluster and factor analyses well agree and reaffirm the enrichment causes of potentially toxic elements are a coal combustion at thermal power stations (B, Bi, Ca, Mo, S and Sr) and traffic emissions (Cu, Pb, Sn and zn). Spatial distributions of trace elements in the districts of Ulaanbaatar city were obtained by ordinary kriging. It is illustrated that the different principal components define the various origins and patterns of accumulation of trace elements in soils. The supplementation of data set by the concentration of organic carbon and the species of elements could help to identify the sources of such elements as P, Ni, Al, Fe, Ca, Ba, Bi, Cr, zn, Sr and Sb in urban soils more completely.KEY wORDS: urban surface soils; major and trace element; clayey, silty and sandy fractions; multivariate statistical analysis; ordinary kriging CITATION: Elena V.

“…Urban soils develop under the strong influence of anthropogenic factors and, hence, significantly differ in the main physical and physicochemical properties from the natural zonal soils [1] [2]. The microscopic inhabitants of the urban soils are very responsive to the anthropogenic transformation of their properties, which affects the parameters of algal-cyanobacterial communities [3] [4], as well as the diversity and composition of soil inverte-brates [5]- [7] and microscopic fungi [8]- [10].…”

Algal-cyanobacterial communities, soil nano-and microfauna, and mycelium of micromycetes were studied in soils of an administrative district of Moscow. To characterize the habitat conditions of microbiota in the soils of different functional zones of the city, the acid-base conditions and the contents of exchangeable and water-soluble nitrogen, mobile heavy metals, and soluble salts were determined. The diversity of species of algal-cyanobacterial communities, the composition of the dominant species, the proportions of different ecological groups of diatom algae, the diversity of soil nano-and microfauna, and the abundance of colorless and colored mycelium in the urban soils were characterized. The analysis of these parameters showed that the degree of technogenic impact on soil microbiota decreases in the following sequence of functional zones of the city: industrial > traffic > residential > recreation.
