“…The pollution mapping of the research area revealed high PTE contents (median Cu – 2.5 g kg −1 , Ni – 7.6 g kg −1 ), which is in good coherence with the previous studies, reporting the content of Cu and Ni peaking to 6 and 9 g kg −1 , respectively (Kashulina, 2017). The outcomes are also comparable to the PTE contents reported for the heavily polluted 3 km buffer zone (Cu: 1.3–3.5 g kg −1 , Ni: 2.5–4.2 g kg −1 ) (Evdokimova et al, 2011). Similar studies in the vicinity of the Sudbury smelters (Canada) also showed soil pollution by Cu and Ni, but in lower contents (max 1.3 g kg −1 for Cu and 0.9 for Ni) (Dudka et al, 1995).…”

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.

“…The adverse environmental impacts of sulfur dioxide and metallic emissions high in Ni and Cu, especially as surface soils contaminants, on the landscapes and watersheds surrounding the industrial complex of the MMC have been detected up to 250–300 km from the industrial complexes as widely discussed in scientific literature for decades ( Reimann et al., 1998 ; Barcan, 2002 ; Evdokimova et al., 2011 ; Koptsik et al., 2016 ; Lyanguzova et al., 2016 ; Kashulina, 2017 ). The industrial barrens created by emissions of the MMC extend for 5–7 km depending on the wind direction, with areas in the prevailing N and S wind being most impacted.…”

The long-term emission impacts of the nickel processing industry in the Kola Peninsula, the largest source of sulfur dioxide and heavy metals emissions in Northern Europe, have created vast technogenic barrens near the mineral industry complexes. The pace of rehabilitation using the improved remediation technologies to enhance sustainable environmental management and regional economic development is of crucial social and economic importance. In a 120-day incubation experiment, we evaluated the prospects for the restoration of two soils at different degradation stages via carbon pool regulation comparing to mineral ameliorants – NPK fertilizer, and liming agent. Organic additives used included a humic preparation based on an alkaline brown coal extract, wood-derived biochar, and peat-derived gel, supplied by mycorrhizae fungi. The results demonstrate that the selected organic amendments are suitable for restoration of acidic metal contaminated soils. Specifically, the treatments provided a measurable increase in soil carbon content, a marked decrease in acidity, a decrease in extractable metal contents, together with an enhanced nutrient uptake and vegetative growth. A stabilization effect increased from biochar to peat-gel, liming agent and humic preparation, with an accompanying increase in soil pH. Although biochar showed a reduced ability to metal stabilization, the associated treatments were the most productive. The most effective amendments in multi-metallic contaminated soils need to be able to stabilize bioavailability of metals, adjust pH to the optimum for plant growth, and regulate nutrient consumption.

“…Soil and vegetation characteristics are described in detail in previously published articles (Evdokimova et al 2011.There have been identified three environmental impact area zones related to the Kandalaksha Aluminum Plant in terms of fluorine content in the organic horizon (0-3(7) cm) and the condition of vegetation, too. The definitions of these three zones were identified: the zone of maximum pollution at the distances up to 2.5 km from the pollution source (F >1200 mg/kg; pine trees were significantly damaged by pollutants as indicated by multiple dead branches in the lower and middle parts of tree crowns and ground Fig.…”

The species diversity and the structure of the opportunistic fungi complexes in the forest Albic Podzols under the impact of the Aluminum and Copper-Nickel Plants emissions, as well as in the Hortic Anthrosol contaminated by the oil products (diesel fuel, gas condensate, mazut) in the north-west region of Russia (the Kola Peninsula) have been investigated. The share of the opportunistic fungi increase up to 15% in the zones of the Aluminum and Copper-Nickel Plants emissions comparable to the background soil, and up to 20-25% in the soils contaminated by the oil products has been revealed. The majority of the fungi species belong to the following genera: Penicillium, Aspergillus, Mucor, Lecanicillium, Phoma and Cladosporium. The structure of the fungal complexes has changed in the polluted soil, that is, the species abundance and the frequency of the opportunistic fungi occurrence have increased. The strains of the fungi isolated from the contaminated soil reveal the potential pathogenicity in a greater degree, than the strains isolated from the clean soil. 55% of the total amount of fungi strains isolated from the soils contaminated by the Aluminum Plant emissions had the potential pathogenicity. The most dangerous for a human’s health were Amorphotheca resinae, Aspergillus fumigatus, A. niger, Paecilomyces variotii, Penicillium commune, P. purpurеogenum, Trichoderma viride isolated from the soils contaminated by the Aluminum Plant emissions; and P. aurantiogriseum, P. glabrum, P. commune, P. simplicissimum, Rhizopus nigricans isolated from the soils contaminated by the oil products. Those species revealed protease, phospholipase activity, as well as the growth ability at the temperature 37°C
