“…The negative effects of salt pollution include changes in soil biogeochemistry and composition, and characteristics such as decreased aeration and decreased soil permeability with increased erosion. Currently developed hydro-technical technologies at the tailing storage have to be followed by carefully planned bioremediation strategies (Mokryi, Petrushka et al 2023). Here we considered the potential of the basket willow ( Salix viminalis ) for the tailing storage bioremediation.…”

Manipulating the rhizosphere microbiome to enhance plant stress tolerance is an environmentally friendly technology and a renewable resource to restore degraded environments. Here we considered the Salicornia europaea rhizosphere community, and the ability of the phytoremediation plant Salix viminalis to recruit its beneficial microbiome to mediate the pollution stress at the Stebnyk mine tailings storage. The tailings contain large amounts of brine salts and heavy metals that contaminate the ground water and surrounding areas, changing soil biogeochemistry and causing increased erosion. The species richness of the endophytic bacterial community of S. viminalis roots was assessed based on observed OTUs, Shannon- InvSimpson, and evenness index. Our results show that biodiversity was decreased across the contamination zones and that S. europaea supplementation significantly increased the species richness. Our results also indicate that the number of dominating OTUs was not changed across zones in both S. europaea-treated and untreated bacterial populations, and that the decrease in richness was mainly caused by the low abundance of OTUs. The importance of engineering the microbial communities that support the genetic diversity of degraded environments and the challenges with high throughput metabarcoding databases are discussed.

Manipulating the rhizosphere microbiome to enhance plant stress tolerance is an environmentally friendly technology and a renewable resource to restore degraded environments. Here we suggest a sustainable bioremediation strategy on the example of Stebnyk mine tailings storage. We consider Salicornia europaea rhizosphere community, and the ability of the phytoremediation plant Salix viminalis to recruit its beneficial microbiome to mediate the pollution stress at the Stebnyk mine tailings storage. The tailings contain large amounts of brine salts and heavy metals that contaminate the ground water and surrounding areas, changing soil biogeochemistry and causing increased erosion. The species richness of the endophytic bacterial community of S. viminalis roots was assessed based on observed OTUs, Shannon-InvSimpson, and evenness index. Our results obtained using the plant-based enrichment strategy show that biodiversity was decreased across the contamination zones and that S. europaea supplementation significantly increased the species richness. Our results also indicate that the number of dominating bacteria was not changed across zones in both S. europaea-treated and untreated bacterial populations, and that the decrease in richness was mainly caused by the low abundant bacterial OTUs. The importance of selecting the bioremediation strains that are likely to harbor a reservoir of genetic traits that aid in bioremediation function from the target environment is discussed

At the United Nations Climate Change Conference (COP26) in Glasgow in autumn 2021, world leaders and participants decided to phase out coal power. Ukraine is committed to shutting down its state-owned coal-fired power plants by 2035. Natural and technical geosystems in coal mining areas have a significant impact on environmental and anthropogenic environmental safety and require comprehensive research This scientific article delves into the thorough examination of the impact of augmented radiation levels in the waste piles of the Nadiya mine in the Lviv-Volyn coal basin. The exploitation of the Lviv-Volyn coal basin has led to many negative changes in the flora and fauna, atmosphere, hydrosphere and biosphere, and has significantly affected the life and health of the Ukrainian population. The Nadiya mine waste heaps are located on the outskirts of the town of Sosnivka, Chervonohrad district, Lviv region (Ukraine) on fluvioglacial sands, partially on alluvial sediments of the Western Bug River. The height of the waste heaps is over 42 m and the area is 12 hectares. The spoil heap is bounded by woody vegetation on both sides and agricultural land on the other. The spoil heap is composed of burnt and unburnt rocks with sulfuric acid zones on the burnt pieces. Spontaneous combustion is observed on the spoil heap, in particular at the top, where the radiation background was investigated. The radiation power at the top of the spoil heap was found to be significantly higher than in other areas. The investigations of the radiation background of the Nadiia mine spoil heap showed the equivalent dose rate at the top of the heap, which is 0.42 μSv/h, exceeding the permissible standards of 0.3 μSv/h. It should be noted that the excess radiation background is due to the combustion of rock.
