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.

Impacts of non-ferrous metal mining on soil heavy metal pollution and risk assessment

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 969, P. 178962 - 178962

Published: Feb. 28, 2025

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.

Role of white rot fungi in sustainable remediation of heavy metals from the contaminated environment

Mycology&#58 An International Journal on Fungal Biology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 17

Published: Sept. 20, 2024

Heavy metal contamination has severe impacts on the natural environment. The currently existing physico-chemical methods have certain limitations, restricting their wide-scale application. use of biological agents like bacteria, algae, and fungi can help eliminate heavy metals without adversely affecting flora fauna. Due to inherent ability withstand adverse environmental conditions, nowadays, mycoremediation approaches are receiving considerable attention for removal from contaminated sites. In this review, we emphasised role white rot in remediation along with different factors influencing biosorption, effects exposed fungi, mechanisms involved. Bibliometric analysis tools been applied literature search trend research fungi-mediated removal. Annual growth rates average citations per document 5.08% 35.48, respectively.

Effects of Simulated Acid Rain on Photosynthesis in <em>Pinus massoniana</em> and <em>Cunninghamia lanceolata</em> in Terms of Prompt Fluorescence, Delayed Fluorescence, and Modulated Reflection at 820 nm

Published: Jan. 10, 2024

The effects of simulated acid rain (SAR) on the photosynthetic performance subtropical coniferous species have not been thoroughly investigated. In this study, we treated two species, Pinus massoniana (PM) and Cunninghamia lanceolata (CL), with SAR then analyzed activities via simultaneous measurement prompt fluorescence(PF), delayed fluorescence(DF), modulated reflection at 820 nm(MR820). Following low-pH treatment, I–P phase OJIP curves PM CL decreased significantly K-band L-band were detectable. fluorescence for both as pH solution decreased, a more significant decrease in I1 peak than I2 peak. According to MR820 curve, exposure stress inhibited rapid slow increase transients CL. gradients decreasing increasing phases lower 2.5. addition, light energy captured per unit area (ABS/CSm) quantum yield electron transfer (ETO/CSm), but it increased accumulation QA−, thereby primary photochemical efficiency (TRO/CSm, φPO). These changes photosystem II (PSII) resulted maximum PSII (Fv/Fm) index (PIABS). Moreover, was protected from thylakoid membrane photodamages through heat dissipation (DIO/CSm) response SAR. δRO observed PM, Considered together, study findings suggest that treatments can chlorophyll contents damage OEC CL, which obstructs electrons donor acceptor sides PSII. However, is better able withstand likely because activation protective mechanism (reflected by change δRO). Therefore, forest areas severely affected rain, may need be PM.
