“…This horizon is typical for cities (for instance, Arkhangelsk, St. Petersburg, Petrozavodsk, and Vorkuta) where peat is used for remediation [8,15,20,25]. The RAT and RT layers and/or horizons usually contain small amounts of artifacts (no more than 5-10%).…”

“…The position of types and subtypes of urban soils in the Russian soil classification is determined by the structure of their profiles, the presence and thickness of the UR horizon and/or natural horizons, the nature of the substrate, and the degree of its changes in the course of the cur rent pedogenesis. Soil forming substrates of urban soils permanently grow up [2,8,15,24] allowing us to consider the urban pedogenesis to be synlithogenic. Many urban soils are fast developing young soils on various newly formed technogenic deposits or abraded natural sediments and technogenic structures (recla mation bodies).…”

Inclusion of soils and soil-like bodies of urban territories into the Russian soil classification system

The results of the Internet discussion on the classification of urban soils aimed at evaluating their possible inclusion into the modern Russian soil classification system adopted by a wide range of specialists are presented. The first step was to address the urban diagnostic horizons as the basis for identifying soil types according to the rules of the Russian soil classification. New diagnostic horizons were proposed for urban soils: urbic (UR), filled compost-mineral (RAT), and filled peat (RT). The combination of these horizons with other diagnostic horizons and layers of technogenic materials correspond to different soil types. At the subtype level, the diagnostic properties (qualifiers) that may reflect both natural phenomena (gley, alkalinity) and technogenic impacts on the soils (urbistratified; phosphatic; or poorly expressed urban-ur, rat, rt) are used. Some corrections were proposed for the system of parent materials in urban environments. Urban soils formerly described in another nomenclature-urbanozems, urbiquasizems, and culturozems-are corre lated with the taxa in all the trunks of the system. The proposals accepted can be used for the next updated version of the new Russian soil classification system.

“…The extra BC input from wood and fossil fuel combustion for heating may be another important C source, increasing urban C stocks in cold and temperate climates compared with the tropics. For example, substantial inputs of charcoal and biochar into urban soils were reported for industrial and residential areas in Vorkuta town in the polar region (Dymov, Kaverin, & Gabov, ; Lehndorff et al, ). However, we have not found straight patterns between BC stocks and climate conditions that might be explained by the predominant effect of nonclimatic factors (e.g., functional zoning) and data limitations for BC compared with other C forms.…”

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.

“…Within the urban ecosystem, soils are distinguished by composition and properties (Short et al, 1986). Natural landscapes are transformed into anthropogenic with a local change in biochemical cycles (accumulation and removal of chemical elements (Adama et al, 2016;Dymov et al, 2013). Urban soils, as a depositing component of the urban landscape, accumulate many trace elements, including heavy metals and metalloids, as well as organic compounds that are toxic to living organisms (Kicińska, 2019).…”

According to the main chemical indicators, the soils of the city differ signifi cantly from their natural analogue. A signifi cant part of the territory of cities is affected by negative processes that affect the ecological functions of soils. Due to the intensifi cation of the anthropogenic impact, surface air pollution increases, soil profi les are disturbed, acidity and alkalinity change, and the biodiversity of soil microfl ora is reduced. This paper presents the results of a study of alluvial urban soils of parks and the industrial zone located in Saint Petersburg in Russia. A morphological description and the basic physical parameters of soils are determined. The content of priority toxicants (heavy metals, benzo[a]pyrene, petroleum products) was conducted, as well as an epidemiological study of soils for the presence of pathogenic organisms. The data obtained show that heavy metals accumulate in alluvial soils, about 35% of the studied soils exceeded permissible concentrations. The content of PAHs in soils also exceeded up to 34 of the maximum permissible concentration. We observe differences in the sanitary and hygienic conditions of alluvial territories specially designated for recreational area. According to the results of microbiological studies, pathogenic organisms are present in soils, but their content varies within acceptable limits of Russian Federation.
