“…Functional zoning had a significant impact on SIC stocks, contributing 20–60% to the total variance (main effect ANOVA), and this effect was higher for the subsoil than for the topsoil. SIC stocks increase in subsoil due to concrete rubble or lime gravel, in contrast to the topsoil, where the SIC is deposited mainly by dust (Prokof'eva et al, ). The largest BC stocks are located along roadsides and in residential zones (2–3 times more than that in suburban natural areas), corresponding to the main BC sources: fossil fuel and wood combustion (J. Yang et al, ).…”

“…All natural soil‐forming factors lead to soil development directed down the profile (except Fluvisols and Andosols; Dobrovolsky & Urussevskaya, ). In contrast, urban soils tend to grow upward (so‐called synlithogenic; Prokof'eva et al, ). Consequently, ancient cultural layers are covered by much younger sediments.…”

“…Heating industries and fossil fuel combustion are important BC sources (Preston & Schmidt, ; Rawlins et al, ). Cement and construction industries increase SIC stocks by input from dust deposition and disposal of construction wastes with high lime contents (Prokof'eva, Kiryushin, Shishkov, & Ivannikov, ; Stroganova et al, ).…”

“…This is partly similar to the formation sequences of Fluvisols (Zielhofer, Recio Espejo, Núnez Granados, & Faust, ). The trend of topsoil's upward growth is referred to as ‘synlithogenic’ soil formation, which is rare under natural conditions (Andosols and Fluvisols), but typical for urban soils (Prokof'eva et al, ). Consequently, and in contrast to most natural soils, the pedogenic age of urban topsoils is always younger than that of subsoils.…”

Urban soils as hot spots of anthropogenic carbon accumulation: Review of stocks, mechanisms and driving factors

2018

Urban soils and cultural layers may accumulate C over centuries and consequently large C stocks may be sequestered beneath cities. Processes and mechanisms leading to high C accumulation in urban soils remain unknown. Data on soil organic carbon (SOC), soil inorganic carbon (SIC), black (pyrogenic) carbon (BC), and nitrogen contents and stocks in urban soils were collected from 100 peer‐reviewed papers. The database (770 data points for SOC, SIC, and BC stocks from 116 cities worldwide) was analysed considering the effects of climate and urban‐specific factors (city size, age, and functional zoning) on C stocks. The processes of C accumulation specific for urban soils were analysed, and C sequestration rates were assessed. For the wide range of climatic conditions, total C content in urban soils was 1.5–3 times higher, and C accumulation was much deeper compared with natural soils, resulting in 3–5 times larger total C stocks. Urban SOC stocks increased with latitude, whereas SIC stocks were less affected by climate. City size and age were the main factors explaining intercity differences in C stocks. The intracity variability of C and N stocks was dominated by functional zoning: Large SOC and N stocks in residential areas and large SIC and BC stocks in industrial zones and roadsides were consistent across all climates and for cities of various sizes and ages. Substantial amounts of SOC, SIC, and N are sequestered in the subsoils, cultural layers, and sealed soils, underlining the importance of these hidden stocks for C assessments. Long‐term С input from outside the cities and associated C accumulation coincided with upward soil growth of ~50 cm per century, and continuous accumulation of 15–30 kg C/m2 per century in urban soils and cultural layers. We conclude that, despite the relatively small area of cities, urban soils are hot spots of long‐term soil C sequestration worldwide, and the importance of urban soils will increase in future with global urbanization.

“…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.…”

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

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.
