“…Consequently, low values of C/N ratio favour bacteria and they dominate in N-rich soils [95]. Therefore, our results confirmed that soil organic matter content is the primary factor influencing soil fungal abundance and activity [75] and in urban soil the decrease of SOM quantity and quality leads to less fungal fraction on total microbes, by inhibiting fungal activity [96]. The lower efficiency of the investigated soils to C sequestration and the microbial activity linked with the faster bacterial turnover compared to the fungal one is also highlighted by the biological fertility index (BFI).…”

The assessment of Technosols quality in urban environments is pivotal for the maintenance of ecosystems impacted by human activities. The study was performed on Technosols constructed in experimental mesocosms in the suburban area of Naples (Southern Italy) to highlight changes in the main soil properties over eight years and to identify the most suitable indices at quality monitoring. In this study, several chemical, biological, and integrated indices were analysed to evaluate the mineral accumulation, potential ecological risk, edaphon activity, fertility, and the overall soil quality. The Technosols showed alkaline pH, nitrogen ranged from 24.5 to 39.5 g kg−1, high organic matter contents above 40 g kg−1, and there were no evident processes of soil compaction. Heavy metals (Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Zn) did not exceed the thresholds defined by the Italian law for urban soils, despite their volcanic components. During eight years, the chemical indices depicted changes in the elements balance and increase in ecological risk; the biological indices indicated a reduction in the fungal fraction (fivefold) and in the resources utilisation and carbon storage. The soil quality index with all parameters highlighted the reduction in the soil quality (from 0.78 to 0.65) due to the decrease of the chemical quality, the increase of microbial stress conditions, and changes of the microbial composition, underlining the importance of integrating chemical and biological information for monitoring Technosols.

“…The intensive development of the region, which has a population of more than 700,000 people, refused from the discovery of numerous deposits of mineral resources, which have been actively developed since the first half of the 20th century. Their extraction, processing, and transportation has a constant negative impact on the environment, including pollution of both soils [42,43] and water bodies [4,[44][45][46][47][48][49][50][51][52]. At the same time, the territory of the peninsula is marked on the map "Global geography of incident threat to human water security and biodiversity" as an area with a low risk of possible pollution.…”

The Arctic region of Russia is rich with natural water resources. Some residents of this area prefer to use water from spring sources instead of tap water. However, the elemental composition for most of the springs is unknown, making it very important to regularly update water quality data. In this paper, the chemical composition of 24 natural springs near large cities of the Murmansk region were identified via titration, potentiometry, and mass spectrometry analysis with the low detection limits. The concentrations of a considerable number of micro-components have been determined for the first time. Concentrations of some hazardous pollutants have been found in spring water that exceed Russian hygienic limits by 2.5 times. In terms of chemical indicators, it was shown that in accordance with European and national water standards, only half of the tested natural water sources in the Murmansk region can be used for drinking water. The preferential spring was recommended near each major city in the region according to a set of chemical parameters. The results of chemical composition of the spring waters were disseminated publicly by placing the tags with QR codes with the link to the cloud storage near each studied spring.

“…The Cu‐Ni smelter [Kola Mining and Metallurgical Company ( MMC), former «Severonickel»] is among the leading global producers of nickel, copper, and cobalt and, therefore, one of the most significant sources of metal emissions in Northern Europe. Founded in 1938, the MMC plant is active nowadays, and its annual emissions estimated up to 40 Gg are deposited on vast areas about 300 km distance from the source (Nikanov et al, 2020; Slukovskaya, Vasenev, et al, 2020). The measures taken in 1999 under the environmental protection strategy reduced the gross emissions of non‐soluble metal compounds to 1608–1780 t for Ni and 877–1096 t Cu reported during recent years (Nikanov et al, 2020).…”

High‐resolution mapping of soil pollution by Cu and Ni at a polar industrial barren area using proximal and remote sensing

Industrial pollution by potentially toxic elements (PTE) remains a key environmental threat, resulting in soil and ecosystem degradation. Remediation of the industrial barrens is challenging in polar regions, where plant growth is hampered by severe climatic conditions. High‐resolution mapping of soil pollution is needed to support soil remediation and management projects. The distribution of nickel (Ni) and copper (Cu) was analyzed in the topsoil within the industrial barren around the Ni and Cu smelter in Kola Peninsula, Russia using a field‐portable XRF analyzer. Bulk Cu and Ni contents were measured at 84 observation points within the area of two hectares planned for remediation. The PTE content varied between 0.2 and 9.0 g kg−1 for Cu and between 0.2 and 21 g kg−1 for Ni. The area was surveyed with unmanned aerial vehicles and differential global navigation satellite systems to obtain a high‐accuracy digital terrain model for exploring the factors behind the spatial variability. Field observations were interpolated by regression kriging with different input resolution of auxiliary data (0.5–1.0–1.5–2.0 m) and different regression models (gradient boosting machines and multiple linear regression). Model performance and validation showed that 1.0–1.5 m resolution of auxiliary data were the best for projecting Cu and Ni topsoil contents within the study site. The soil type and topographic wetness index were the most important variables explaining Cu and Ni content variability.
