At present, contamination due to toxic metals is a global concern. The management of problems caused by heavy relies on stabilization/solidification, which the most effective technique for control metal pollution in soil. This study examined immobilization efficiency various phosphate-based binders (Na3PO4, Na2HPO4, NaH2PO4), addition ordinary Portland cement (OPC), MgO, and CaO, stabilization multi-metal-contaminated soils. Moreover, this focused leachability copper, nickel, zinc, lead, cadmium, manganese (Cu, Ni, Zn, Pb, Cd, Mn, respectively) over different time periods with concentrations. Batch leaching experiments were conducted determine ratios percentages concentrations, along measuring pH values leachates. Our results indicate that use OPC was validated its superior performance across all present soil, but particularly regard high formation stable hydroxides values, assisted abating metals’ solubility. Additionally, binders, despite being environmentally favorable, found be less effective, Pb Cu, exceeded non-hazardous waste limits. MgO showed reasonable compared OPC; other hand, CaO exhibited increased time. Therefore, research serves primarily highlight more suitable soil remediation at industrial sites construction infrastructure. Meanwhile, are shown appropriate eco-friendly, non-load-bearing applications.

The rhizosphere hosts diverse microbes crucial for plant growth. This is because roots secrete organic compounds, thereby enriching the with essential nutrients. Biochar improves soil quality, while nano-biochar shows promise in contaminant adsorption. Its production from biochar easily achievable through top-down methodologies including hydrothermal synthesis, ball-milling, sonication, and centrifugation. advantages of employing are evident several aspects. Nano-biochar exhibits enhanced properties such as greater surface area, increased porosity, reactivity compared to bulk-biochar. area allows adsorption capacity, enabling effectively immobilize contaminants environment. In this review, detailed interactions applications summarized. interacts by electrostatic interaction, cation-π redox reactions, influencing microbial communities resilience. can adsorb rhizosphere, heavy metals pollutants. Thus, it helps alleviate abiotic stresses, nutrient availability, supports Furthermore, mechanistic processes oxidation, mineral dissolution, matter release, mechanical fragmentation discussed, culminating ageing formation, which creates a conducive environment microorganisms. review examines nano-biochar-rhizosphere interactions, highlighting their effects on plant-soil dynamics Future research should address synthesis scalability safety concerns unlock nano-biochar's potential sustainable agriculture environmental management.

Polyaromatic hydrocarbons (PAHs) pose a global threat in both developed and developing countries due to their adverse effects on various ecosystems. The low molecular weight (LMW) PAHs, widely used everyday life, are potential contaminants. Being highly volatile, they often uptaken by plants enter the food chain, necessitating an effective biodegradation system. Over last decade, research has advanced significantly bacterial of PAHs composed more than three rings. This review focuses levels PAH soils worldwide highlights diverse communities found these capable degrading LMW-PAHs. It also elucidates mechanisms LMW-PAH degradation bacteria. Various studies indicate that while individual bacteria contribute degradation, consortia promise better efficiency. underscores need for further bioremediation using networks development methods targeting wide range In conclusion, optimizing enhancing environmental conditions could improve LMW-PAHs, reducing ecological health impacts.
