Soil contamination by lead, zinc, iron, manganese, and copper is a widespread environmental issue associated with the mining industry. Primary sources include activities, production processing operations, waste disposal management practices, atmospheric sediments. degradation, water pollution impacting aquatic ecosystems, plant absorption leading to agricultural product contamination, health risks exposure copper, along effects on fauna biodiversity, constitute primary impacts of contamination. In this study, diverse sampling analysis methods, geographic information systems, remote sensing techniques are investigated for monitoring assessing soil these metals. modification techniques, phytoremediation, other strategies reduction considered among most crucial, alongside protection risk strategies. Finally, article explores innovative methods solutions mineral remediation, application green chemistry sustainable practices in industry, utilization artificial intelligence controlling heavy metal ion pollution.

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.

Extensive and unregulated groundwater extraction for irrigation in the arid inland basins of Northwest China has led to a continuous increase depth agricultural areas. This significantly altered distribution soil ions, making it difficult predict their evolution dynamic patterns. In this study, we used space-for-time substitution approach elucidate ion under changing depths. Experiments were conducted three typical areas with varying depths, that is, below 5 m, 5–10 above 10 m Korla, Xinjiang, China. Soil samples collected from five profiles at depths 0–180 cm measure moisture, salinity, major content. An innovative research framework was developed examine relationship between using ratios, principal components, hierarchical clustering, correlation analyses. aims reveal dynamics, correlations, mechanisms distribution, representative composition as increases The results showed increased, chemical type shifted Ca-SO4 Na-SO4 mixed types, an SO42− Na+ content profile. sodium adsorption ratio (SAR), total dissolved solids (TDS) higher shallow than deep groundwater. Groundwater negatively correlated cations anions (K+, Na+, Ca2+, Mg2+, Cl−, SO42−, NO3−). Meanwhile, positive exists CO32−. ions is primarily governed by influenced multiple factors. Evaporation dominant factor areas, whereas mineral rocks plays crucial role These findings provide scientific support strategic water-resource management policies sustainable development strategies regions.

The high consumption and cost of cement are the bottleneck problems that limit development cemented tailings backfilling technology. low-consumption backfill is immersed in a weak acid/alkaline groundwater environment for long time. Reducing can easily lead to such as sudden decrease strength leakage heavy metals. Through monolithic leaching test static uniaxial compressive tests, metals’ concentration backfills different pH soaking solutions were measured at times. Results show lower will result CTB higher rate metal leaching. Long-term exposure an acidic/alkaline instability destruction structure. A microscopic examination reveals creation hydration products improve structure’s compactness while also lowering internal porosity but solidify ions various ways. first-order reaction/diffusion model (FRDM) better evaluate behavior CTB. This study helps technology, thereby contributing sustainable mining geotechnologies.
