“…Although soil capacity to buffer and immobilize metals is affected by different soil properties, processes, and regimes, soil pH, SOC, and texture, which were used in this study, are the factors most highly recognized and considered in research (Slukovskaya et al., 2019), soil management practices (Vasenev et al., 2017), and regulations (FCHE of Rospotrebnadzor, 2010). The effect of soil texture is quite straightforward, with higher holding capacity reported for soils with clayey texture (Luo et al., 2011).…”

“…(2015) to be among the main “ecosystem disservices” of urban soils, decreasing their socioeconomic and environmental value. On the other hand, urban soils can perform as geochemical barriers and buffer heavy metal(loid) (HM) contamination (Kosheleva, Kasimov, & Vlasov, 2015; Slukovskaya et al., 2019). The capacity to immobilize and buffer HMs can be considered an important regulating service provided by urban soils (Adhikari & Hartemink, 2016; Levin et al., 2017).…”

Urbanization is responsible for some negative environmental consequences, including soil contamination by heavy metal(loid)s (HMs). At the same time, urban soils can buffer HMs and perform as geochemical barriers. For the case of Moscow city, the soil contamination by multiple HMs as well as soil buffer capacity was analyzed, mapped, and considered to assess urban soils as geochemical barriers. Comparison with the health standards indicated contamination by different HMs in 30–60% of the observations, and Zn and Cd were the most widely spread contaminants. “Hotspots” of contamination were shown in the central and eastern districts of Moscow with the most intensive traffic and congregation of industries. New spatial patterns were shown for soil performance as geochemical barriers to multiple HM contamination. High buffer capacity of loamy and slightly alkaline soils in the city center with high contamination level resulted in a better performance of soil geochemical barriers compared with some green zones and natural areas where low buffer capacity of loamy sandy and slightly acid soils were not enough to resist even relatively low contamination. The capacity of urban soil to perform a geochemical barrier for contamination by HMs is an important ecosystem service. Spatially explicit information on this ecosystem service can be highly relevant to assess environmental and health risks of urban soil contamination and to support decision making in urban planning and sustainable development.

“…Séré et al (2008) defined the construction of a Technosol as a process "using wastes and industrial by-products which are formulated and stacked in layers to build a new soil profile over in situ degraded substrates". Prokofyeva et al 2011, on the other hand, define constructed Technosols ("constructozems") as bodies of soil with complicated stratification, greater than 40-50 cm in thickness, that are created for special purposes such as salt protection in semi-and severely dry areas (Smagin, 2012). In this review, we will define constructed Technosols as the result of the voluntary action of creating a "soil" (soil made by humans) using artefacts (i.e., technogenic materials, particular wastes, or seminatural materials including deep materials such as sediments or soil material from C horizons) and intentionally shaping them to provide a suitable environment for vegetation growth.…”

Abstract. With the rise in urban population comes a demand for solutions to offset environmental problems caused by urbanization. Green infrastructure (GI) refers to engineered features that provide multiecological functions in urban spaces. Soils are a fundamental component of GI, playing key roles in supporting plant growth, infiltration, and biological activities that contribute to the maintenance of air and water quality. However, urban soils are often physically, chemically, or biologically unsuitable for use in GI features. Constructed Technosols (CTs), consisting of mixtures of organic and mineral waste, are man-made soils designed to meet specific requirements and have great potential for use in GI. This review covers (1) current methods to create CTs adapted for various GI designs and (2) published examples in which CTs have been used in GI. We address the main steps for building CTs, the materials and which formulae should be used to design functional CTs, and the technical constraints of using CTs for applications in parks and square lawns, tree-lined streets, green buffer for storm water management, urban farming, and reclaimed derelict land. The analysis suggests that the composition and structure of CTs should and can be adapted to available wastes and by-products and to future land use and environmental conditions. CTs have a high potential to provide multiple soil functions in diverse situations and to contribute to greening efforts in cities (and beyond) across the world.

“…Analysis of soil polluted by emissions of non-ferrous smelters is not a routine due to the extremely high levels of contamination of Cu and Ni that belong to the potentially toxic metals (PTM) [24]. Over the decade, field experiments have been carried out on these territories in order to remedy the highly polluted and degraded soil using mining wastes of various mineral compositions [25,26]. In particular, the experiment conducted on peat soil, because this type of soil is dominating in depressions.…”

An evaluation of fraction composition and transformation of metal compounds emitted by metal ore processing enterprises and accumulated in soils is crucial for assessing the environmental risks of pollution and ecosystem benefit of remediation. The aim of this study was to develop a suitable sequential fractional procedure for metal pollutants for the peat soils matrix in the impact zone of a Cu-Ni smelter. Three experiment series were performed: (a) the study of the effect of ammonium acetate buffer pH in the range of 3.7–7.8 on the soil metal extraction; (b) the study of the effect of additional volume and frequency of soil treatment with solutions on the content of water-soluble, ammonium acetate extractable, and 0.1 N HNO3 extractable fractions; and, (c) the determination of the metal fraction composition in the modified technique. Soil treatment with ammonium acetate buffer with a pH range of 4.5–5.5 was the most appropriate for the determination of mobile compounds of Cu and other metals in highly polluted peat soil. Triple soil treatment with water and ammonium acetate is necessary for the complete extraction of the water-soluble and exchangeable fractions, respectively. Additionally, we propose a procedure of full extraction of the exchangeable metal fraction from peat soils while using single treatment with 0.1 N HNO3. This scheme allows evaluating geochemical mobility of metals and current environmental harm of polluted soils with a high content of organic matter.
