Comprehensive analysis of heavy metal soil contamination in mining Environments: Impacts, monitoring Techniques, and remediation strategies

Arabian Journal of Chemistry, Journal Year: 2024, Volume and Issue: 17(6), P. 105777 - 105777

Published: April 5, 2024

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.

Heavy metal pollution is a serious environmental problem that poses threat to human health and the environment. Water by toxic heavy metals major cause of this problem, it can destroy ecosystems, spread disease, make drinking water unsafe. Biochar promising green adsorbent for removing from water. It derived various biomasses, including agricultural organic wastes, has high carbon content, surface area, stability. These properties enable biochar effectively remove through cation exchange adsorption. This review summarizes recent advances in modification enhanced adsorption metals. discusses advantages, applications, challenges, prospects method. Biochar-based advanced oxidation processes (AOPs) have shown promise decomposition complexes enhancement capacity free ions industrial wastewater. The also highlights research gaps limitations remediation proposes future directions. Future should focus on developing environmentally friendly cost-effective technologies scaling up biochar-based removal applications. Scheme 1 illustrates overall summarized presentation article as graphical abstract.

The immobilization and adsorption mechanisms of agro-waste based biochar: A review on the effectiveness of pyrolytic temperatures on heavy metal removal

Environmental Chemistry and Ecotoxicology, Journal Year: 2024, Volume and Issue: 6, P. 92 - 103

Published: Jan. 1, 2024

The multifunctional properties of biochar make it a promising adsorbent heavy metals for environmental bioremediation. Pyrolytic temperature is key factor that impacts the properties, performance, and mechanisms agro-wastes-derived because physiochemical transformation its structural composition. It has been deliberated increased pyrolysis temperatures strongly enhance specific surface area, pH, high microporosity as well carbon ash content with low cation exchange capacity volatiles content. reason different from related to variations in lignin-cellulose structures moistures agro-waste biomasses. Biochar considered low-cost material shown convenient applicability rural areas developing countries where contamination emerging. A wide range pyrolytic distinctive characteristics biomass their capacities remove metals. Higher can exhibit higher areas, enhanced functional groups, stability than modified biochar. Different exhibited diverse adsorption on such rice husk corncob, efficiency increases selective hexavalent chromium [Cr(VI)], cadmium [Cd(II)] zinc [Zn(II)]. This review aimed understand pristine bioremediation biomasses obtained decision making process production costs. authors propose future investigations metal immobilization unlock full potential
