“…Furthermore, the estimates revealed annual losses in agricultural land, mainly occurred through industrialization, pollution, desertification and urban development 1 . Pollution of soil and water with heavy metals is one of the major stresses that affect agricultural production, local population health, natural resources and the balance of the ecosystem 2,3 . In addition, industrial pollution from heavy metals leads to contamination of sites in a large area, resulting in significant changes in the structure and/or biosphere of the soil as a result of transition activities 4 .…”

Heavy metals are environmental pollutants affect the integrity and distribution of living organisms in the ecosystem and also humans across the food chain. The study targeted the removal of copper (Cu2+) from aqueous solutions, depending on the biosorption process. The bacterial candidate was identified using 16S rRNA sequencing and phylogenetic analysis, in addition to morphological and cultural properties as Azotobacter nigricans NEWG-1. The Box-Behnken design was applied to optimize copper removal by Azotobacter nigricans NEWG-1 and to study possible interactive effects between incubation periods, pH and initial CuSO4 concentration. The data obtained showed that the maximum copper removal percentage of 80.56% was reached at run no. 12, under the conditions of 200 mg/L CuSO4, 4 days’ incubation period, pH, 8.5. Whereas, the lowest Cu2+ removal (12.12%) was obtained at run no.1. Cells of Azotobacter nigricans NEWG-1 before and after copper biosorption were analyzed using FTIR, EDS and SEM. FTIR analysis indicates that several functional groups have participated in the biosorption of metal ions including hydroxyl, methylene, carbonyl, carboxylate groups. Moreover, the immobilized bacterial cells in sodium alginate-beads removed 82.35 ± 2.81% of copper from the aqueous solution, containing an initial concentration of 200 mg/L after 6 h. Azotobacter nigricans NEWG-1 proved to be an efficient biosorbent in the elimination of copper ions from environmental effluents, with advantages of feasibility, reliability and eco-friendly.

“…EC values for arable lands in Poland do not exceed 30 mS•m −1 , as documented within the national monitoring of soil quality [6]. The content of organic matter (OM) in the waste was relatively high as was earlier discovered by Siebielec et al [4]. OM in these wastes apparently originates from residual elemental carbon from the smelting process [3].…”

“…In our own research, we have assessed the activity of microorganisms in the upper layer of the smelter pile, and plant diversity after 19 years of land reclamation through treatment with biosolids and lime. The treatment involved various rates of biosolids and by-product lime, and their combinations [4]. We concluded that high plant species diversity allows greater plant cover resistance to stress conditions caused by metal toxicity and other constrains, such as low water holding capacity and low nutrient availability [4].…”

“…Stuczynski et al [3] and Siebielec et al [4] have described the effectiveness of biosolids and limestone application in smelter waste pile reclamation in the Upper Silesia. The long term evaluation of pilot reclamation sites indicates that the tested technology ensured a fairly compact plant cover in landfill sites, limiting the secondary spread of pollutants.…”

“…Permanent plant cover, which effectively limits the dispersion of metals, might be based on both introduced grasses and spontaneous species to ensure greater plant diversity and the resistance of such an ecosystem [4]. Wójcik et al [5] provided a list of the most common spontaneous plant species growing on flotation and slag waste piles in Piekary Slaskie in Upper Silesia, Poland.…”

The aim was to assess plant driven changes in the activity and diversity of microorganisms in the top layer of the zinc and lead smelter waste piles. The study sites comprised two types (flotation waste—FW and slag waste—SW) of smelter waste deposits in Piekary Slaskie, Poland. Cadmium, zinc, lead, and arsenic contents in these technosols were extremely high. The root zone of 8 spontaneous plant species (FW—Thymus serpyllum, Silene vulgaris, Solidago virgaurea, Echium vulgare, and Rumex acetosa; and SW—Verbascum thapsus; Solidago gigantea, Eupatorium cannabinum) and barren areas of each waste deposit were sampled. We observed a significant difference in microbial characteristics attributed to different plant species. The enzymatic activity was mostly driven by plant-microbial interactions and it was significantly greater in soil affected by plants than in bulk soil. Furthermore, as it was revealed by BIOLOG Ecoplate analysis, microorganisms inhabiting barren areas of the waste piles rely on significantly different sources of carbon than those found in the zone affected by spontaneous plants. Among phyla, Actinobacteriota were the most abundant, contributing to at least 25% of the total abundance. Bacteria belonging to Blastococcus genera were the most abundant with the substantial contribution of Nocardioides and Pseudonocardia, especially in the root zone. The contribution of unclassified bacteria was high—up to 38% of the total abundance. This demonstrates the unique character of bacterial communities in the smelter waste.
