“…The pH of snow water in the territory of the MO MSU is 7.3, which is close to the mean value for residential zones. In Moscow, like most other cities, there is alkalinization of surface soil horizons [29,30,[64][65][66], road dust particles [65,67,68], and bottom sediments of lakes and ponds [69]. Previous studies on Moscow soil water extract and the composition of salts in soils showed a significant increase in the amount of carbonates [29], as opposed to the background sod-podzolic soils that do not contain carbonates at all.…”

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.

“…Significant changes of soil properties along the gradient were also reported, with a gradual decrease in bulk density (from 1.4 ± 0.1 g cm −3 to 0.9 ± 0.3 g cm −3 ) and pH (from 7.3 ± 0.1 to 4.7 ± 0.1) with the distance from the road. Over-compaction and neutralization of soil reaction due to dust depositions are indicators of anthropogenic disturbance usually reported for urban soils [36]. Indirectly, an increase in soil organic carbon content (from 3.3 ± 0.3% near the road to 6.0 ± 0.5% in urban forest) confirms higher anthropogenic disturbance in close proximity to the road.…”

The phylloplane is an integrated part of green infrastructure which interacts with plant health. Taxonomic characterization of the phylloplane with the aim to link it to ecosystem functioning under anthropogenic pressure is not sufficient because only active microorganisms drive biochemical processes. Activity of the phylloplane remains largely overlooked. We aimed to study the interactions among the biological characteristics of the phylloplane: taxonomic diversity, functional diversity and activity, and the pollution grade. Leaves of Betula pendula were sampled in Moscow at increasing distances from the road. For determination of phylloplane activity and functional diversity, a MicroResp tool was utilized. Taxonomic diversity of the phylloplane was assessed with a combination of microorganism cultivation and molecular techniques. Increase of anthropogenic load resulted in higher microbial respiration and lower DNA amount, which could be viewed as relative inefficiency of phylloplane functioning in comparison to less contaminated areas. Taxonomic diversity declined with road vicinity, similar to the functional diversity pattern. The content of Zn in leaf dust better explained the variation in phylloplane activity and the amount of DNA. Functional diversity was linked to variation in nutrient content. The fraction of pathogenic fungi of the phylloplane was not correlated with any of the studied elements, while it was significantly high at the roadsides. The bacterial classes Gammaproteobacteria and Cytophagia, as well as the Dothideomycetes class of fungi, are exposed to the maximal effect of distance from the highway. This study demonstrated the sensitivity of the phylloplane to road vicinity, which combines the effects of contaminants (mainly Zn according to this study) and potential stressful air microclimatic conditions (e.g., low relative air humidity, high temperature, and UV level). Microbial activity and taxonomic diversity of the phylloplane could be considered as an additional tool for bioindication.

“…In this regard, indurated compound soils may have acted as a dense natural barrier to water infiltration, leading to seasonal groundwater saturation and subsequent leaching of the above anthropogenic layer. Accumulation of calcium carbonate linked with soil contamination by construction debris has been observed in modern urban soils (for example, Moscow; Prokof’eva et al ., 2020) and is a frequent feature in many archeological sites (Adderley et al ., 2010; Itkin et al ., 2016). The common characteristics in urban soils are the redistribution of calcium carbonate within the micromass evidenced by the formation of calcitic crystallitic b ‐fabric and the authigenic precipitation of calcite coatings and infillings pedofeatures (Figs 14 and 17).…”

“…Our case study offers the opportunity to anchor continuous microscopic observations with geotechnical parameters obtained from a penetration well acquired during a geotechnical survey in the city of Rome. Several studies demonstrated, in fact, that interpretation of micromorphological features of soil can be used to support the calibration of qualitative and semi‐quantitative compositional and textural data with physical parameters (Aslan & Autin, 1996; Schleuß et al ., 1998; Vissac, 2005; Styllas, 2014; Stoops et al ., 2018; Prokof’eva et al ., 2020, 2021). This approach has important implications in the proper management and monitoring of metropolises built on alluvial plains.…”

“…This approach has important implications in the proper management and monitoring of metropolises built on alluvial plains. Floodplains of urban rivers are prone to soil and subsurface modifications indirectly related to riverine flood influences on groundwater table (Bozzano et al ., 2000, 2008), extensive soil compaction associated with structural degradation and loss of porosity, and pedogenic modification associated with soil sealing and contamination from anthropogenic sources (Jim, 1998; Adderley et al ., 2010; Nirei et al ., 2014; Prokof’eva et al ., 2001, 2020, 2021). Thus, integrating geotechnical and meso and micromorphological observation is important to properly evaluate the soil geomechanical properties and adequately assess geological influences on environmental and engineering hazards.…”

Compositional, micromorphological and geotechnical characterization of Holocene Tiber floodplain deposits (Rome, Italy) and sequence stratigraphic implications

et al. 2022

This study reports a high-resolution micromorphological characterization of floodplain deposits to investigate the relationships among compositional, textural and geotechnical data, and integrate soil micromorphology with sequence stratigraphy. Compositional and textural characterization of facies associations and soil features are calibrated against geotechnical parameters. The latter, obtained from cone penetration and pocket penetrometer tests from a borehole advanced 60 m into the Tiber channel belt and floodplain, show that depositional features and post-depositional modifications are intrinsically associated with cone penetration test parameters: cone resistance; sleeve friction; and friction ratio. Petrographic and micromorphological features document pedogenetic modifications across stratigraphic markers evidenced by faunal and plant activity, accumulation of peat, and typified by precipitation of heavy metals, iron oxides and secondary carbonates. All of these features developed in correspondence with alluvial flooding surfaces that are correlated with non-marine and marine flooding surfaces recognized in the transgressive and highstand coastal and lagoonal deposits of the Tiber Depositional Sequence. These observations may serve as a model to reconstruct the sequence-stratigraphic evolution of ancient relict soils. Nevertheless, additional criteria (for example, their stratigraphic position and correlative surfaces) are necessary to adequately interpret the genesis of such low-rank stratigraphic surfaces. This work demonstrates that a combination between sedimentological and stratigraphic observations and soil micromorphology can be critical to supplement field observations and determine the relative effect of pedogenic and depositional processes on the organization, composition and texture, and geotechnical properties of floodplain in urban areas.
