Mining activities significantly contribute to soil contamination, posing risks the environment and human health. This study evaluates environmental health impacts of four non-ferrous mining types, which have been rarely examined globally. It highlights gaps in existing datasets from selected sites sampling practices, correlating pollutants with atmospheric variables. Overall, geoaccumulation index (Igeo) all mine types were order Hg > Cd As>Cu Pb Zn Ni Cr Mn Co indicating that are main metals pollution associated activities. Notably, highest As contamination (Igeo: class 6) occurs copper mines China, Russia, Portugal, lead‑zinc Sweden Mexico. was most severe soils across Tunisia, Ireland, Spain, Slovenia, Mexico, France, North Macedonia, Bulgaria, Egypt, while uranium USA showed notably lower levels 2). higher gold mine-associated Iran, Myanmar, Brazil Nigeria. About half faced ecological areas Vietnam, Sweden, Cyprus, Portugal had only 8 % category. Gold Nigeria, considerable Hg, whereas Germany Bulgaria a risk, due better management. The primary exposure route for heavy is ingestion, hazard (HI) non-carcinogenic being acceptable elements, except As. Carcinogenic present Brazil, UK. Hence, this review underscores urgent need address metal global offers policy recommendations effective management restoration efforts.

Cork oak and pine bark, two of the most prolific byproducts European forestry sector, were assessed as biosorbents for eliminating potentially toxic elements (PTEs) from water-based solutions. Our research suggests that bioadsorption stands out a viable environmental eco-friendly technology, presenting sustainable method extraction PTEs polluted water sources. This study aimed to evaluate compare efficiency cork powder bark biosorbents. Specifically, adsorption Fe, Cu, Zn, Cd, Ni, Pb Sn at equilibrium studied through batch experiments by varying concentrations, pH, ionic strength. Results adsorption-desorption demonstrate remarkable capacity both materials retain PTE. exhibited maximum retention Fe while they performed poorly Sn, respectively. Nevertheless, showed slightly lower than cork. Increasing pH resulted in showing highest Zn lowest Cd was adsorbed, least The occurred 3.5-5, depending on PTE tested. strength also influenced various materials, with decreased increased. findings suggest could be effective capturing examined PTEs, albeit different efficiencies. Remarkably, demonstrated superior capabilities, which observed vary based specific element experimental conditions. These contribute elucidating bio-adsorption potential these natural specifically their suitability mitigating pollution, favoring recycling revalorization might otherwise considered residue.

Organic materials, such as straw, animal manure, and their processed product biochar, are known to exhibit agronomic effects the ability remediate heavy metal contamination. However, knowledge regarding relative of different organic amendments in soils on immobilization phytoavailability remain limited. Consequently, maize straw (MS), chicken manure (CM), mushroom cultivation waste (MW), sawdust biochar (SB) lead (Pb) wheat plants were investigated this study using pot experiments. The results showed that artificial application Pb reduced soil pH, while increasing total carbon (TOC) cation exchange capacity (CEC) various extents. Furthermore, treatment increased adsorption by grains (0.83 mg∙kg−1), resulting decreased above-ground dry biomass (43.16 g∙pot−1) during maturity growth period when compared with control check (CK) treatment. MS + CM treatments exchangeable fractions soil, but had a limited effect accumulation In contrast, SB effectively pH TOC, decreasing fraction forms oxidizable residual fractions, Moreover, MW also CEC, displaying potential increase addition substantially modifying portioning from less bioavailable fractions. Both significantly concentrations (0.49 0.70 mg∙kg−1,∙respectively), (51.59 54.12 g∙pot−1, respectively). summary, amendments, especially MW, could be an effective measure for enhancing polluted soils, thereby reducing its uptake translocation crops.
