“…In the studied region, such a decrease was noted of Ni and Cu concentrations in needles of spruce [8], pine, and leaves of some dwarf shrubs [12], which the authors connected with the decrease in the amount of metal-containing dust deposited on the surface of the leaves as a result of the reduction of emissions. After intense decrease in atmospheric emissions from the Sredneural'skii Copper Smelter, the decrease in surface contamination of herbaceous plants in meadow ecosystems was noted, which was confirmed by similarity of metal concentrations in not treated and washed plants [14]. Despite the decrease of emissions in 1990-2000 and small fluctuations later on, by the end of growing season of 2018, birch leaves at all monitoring sites around Monchegorsk accumulated greater amounts of the main contaminating metals (Ni and Cu) than in the same season in 2011 [7] (Fig.…”

To assess the state of plants and their response to changes in soil properties, the elemental composition of leaves of widespread and pollution-tolerant species Betula pubescens Ehrh. and Salix caprea L. has been studied near the nonferrous metallurgy enterprises in the Kola Peninsula. The content of nutrients and heavy metals in the leaves of undergrowth on technogenic barrens and remediation sites differing in remediation technologies has been analyzed. According to the results of leaf diagnostics, both species under barren conditions are characterized by a noticeable deficiency of K, Ca, P, and, especially, Mn and Zn. The leaves of both species accumulate Ni, Cu, Co, As, Cr, Fe, Al, Pb, V, and S. Willow leaves contain more Cd, Co, Cr, Ni, Cu, Al, Fe, As, S, Ca, K and less Mn than birch leaves. Chemophytostabilization has little effect, and the covering of contaminated soils with a constructed fertile layer leads to the enrichment of birch and willow leaves with Ca, K, and P. Under conditions of continuing atmospheric emissions and gradual accumulation of bioavailable heavy metals in soils after the remediation, the accumulation of metals in leaves is largely determined by the distance from the pollution source, reflecting the possibility of both root and foliar uptake. The concentrations of Ni and Cu in leaves in 2018 did not decrease compared to 2011. The low, albeit varying, ratios of the contents of heavy metals in undergrowth leaves and in the soil and weak correlation of heavy metal contents in these media indicated that B. pubescens and S. caprea retain their ability to regulate their chemical composition even under extreme conditions of technogenic barrens. At the same time, supporting the protective capabilities of plants via optimizing mineral nutrition and soil acidity in combination with a reduction in atmospheric pollution is a prerequisite for efficient remediation of technogenic territories in the Far North.

“…About ten years ago, emissions from the smelter almost ceased, which initiated the natural recovery of adjoining ecosystems. Recent publications were related to the dynamics of metal concentrations in the environment ( Vorobeichik and Kaigorodova 2017 , Mukhacheva 2017 , Belskaya 2018 , Nesterkov 2019 ) and to the natural recovery of humus forms ( Korkina and Vorobeichik 2021 ), vegetation ( Vorobeichik et al 2014 , Trubina 2020 ), leaf-eating insects ( Belskaya 2018 ), birds ( Belskii and Lyakhov 2021 ), epiphytic lichens ( Mikhailova 2017 , Mikhailova 2020 ), soil macrofauna ( Vorobeichik et al 2019 , Vorobeichik et al 2020 ), grass-layer gastropods ( Nesterkov and Grebennikov 2020 ), small mammals ( Mukhacheva 2021 , Mukhacheva and Sozontov 2021 ) and the common mole ( Vorobeichik and Nesterkova 2015 ).…”

Since the late 1980s, long-term monitoring of terrestrial ecosystems in metal-contaminated areas near the Middle Ural Copper Smelter has been carried out in the Central Urals. As a part of these monitoring programmes, the data on species diversity, community composition and abundance of soil macroinvertebrates continue to be gathered. The dataset (available from the GBIF network at https://www.gbif.org/dataset/61e92984-382b-4158-be6b-e391c7ed5a64) includes a 2004 census for soil macroinvertebrates of spruce-fir forests along a pollution gradient in the Central Urals. The dataset describes soil macrofauna’s abundance (the number of individuals per sample, i.e. the density) and community structure (list of supraspecific taxa, list of species for most abundant taxa and supraspecific taxa or species abundance). Seventeen sampling plots differed in the levels of toxic metal (Cu, Zn, Pb, Cd and Fe) soil contamination from air emissions of the Middle Ural Copper Smelter (heavily polluted, moderately polluted and unpolluted areas). The dataset consists of 340 sampling events (= samples corresponding to upper and lower layers of the 170 soil monoliths) and 64658 rows (2907 and 61751 for non-zero and zero density of taxa, respectively). Arachnida (Araneae and Opiliones), Carabidae (imagoes), Elateridae (larvae), Chilopoda, Diplopoda, Gastropoda, Staphylinidae (imagoes) and Lumbricidae were identified to species level. In contrast, Mermithida, Enchytraeidae, Lepidoptera larvae, Diptera larvae, Hemiptera, Hymenoptera and some other insects were identified to family or order levels. In total, 8430 individuals of soil macroinvertebrates were collected in two soil layers (organic and organic-mineral horizons), including 1046 Arachnida (spiders and harvestmen), 45 Carabidae, 300 Elateridae, 529 Myriapoda, 741 Gastropoda, 437 Staphylinidae, 623 Lumbricidae and 4709 other invertebrates. The presence-absence data on each taxon are provided for each sampling event. An overwhelming majority of such absences can be interpreted as “pseudo-absences” at the scale of sampling plots or study sites. The dataset contains information helpful for long-term ecotoxicological monitoring of forest ecosystems and contributes to studying soil macrofauna diversity in the Urals.

“…Pollution sources are gas emissions, waste water, slag and sludge dumps of industries. Quite a lot of research is aimed at assessing the impact of airborne emissions from metallurgical industries on biotic components of ecosystems (Serbula et al, 2013;Bergman and Vorobeichik, 2017;Nesterkov, 2019). At the same time, insufficient attention is paid to the study of the formation of soils, vegetation and microorganisms on the slag dumps.…”

The metallurgical industry is one of the major pollution sources of natural ecosystems. Now the slag dumps of non-ferrous industries occupy huge areas all over the world. The purpose of this literature review was to assess the knowledge degree of the soils and vegetation formed on the non-ferrous metallurgy slag dumps. Most of the research was carried out for the dumps of the copper-smelting (including old dumps) and lead-zinc industries, the dumps of the nickel and aluminum industries have been studied to a lesser extent. The composition of non-ferrous metallurgy slags, the issues of soil pollution with heavy metals, their bioavailability were discussed. The influence of heavy pollution on the biodiversity of pioneer plant communities on the slag dumps of non-ferrous metallurgy and the floristic composition for abandoned copper ore deposits are noted. The experience of Russian scientists in the reclamation of an aluminum sludge dump and Chinese scientists in the reclamation of zinc production slag dumps are considered. The possibility of introducing waste from the copper smelting slag recycling waste into natural ecosystems was discussed. The analysis of literature revealed gaps in knowledge about the gradual formation of the soil and vegetation on man-made landscapes, about the plant biodiversity in conditions of heavy pollution, ways of their adaptation, and the heavy metals accumulation by different plant species.
