Biochar-mediated remediation of uranium-contaminated soils: evidence, mechanisms, and perspectives

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: March 1, 2024

Abstract Soil contamination by uranium presents a burgeoning global environmental concern, exerting detrimental effects on both agricultural production and soil health. Biochar, carbonaceous material derived from biomass pyrolysis, exhibits considerable potential for remediating uranium-contaminated soils. However, comprehensive review of the biochar fate accumulation in soil–plant systems remains conspicuously absent. In this paper, sources are reviewed, impact immobilization detoxification is analyzed. We reviewed status soils globally found that mining activities currently main sources. Further meta-analysis revealed addition significantly reduced bioavailability shoot accumulation, their effect value 58.9% (40.8–76.8%) 39.7% (15.7–63.8%), respectively. Additionally, enhances microenvironment, providing favourable conditions promoting plant growth reducing mobility. focused mechanisms governing interaction between uranium, emphasising roles played surface complexation, reduction, ion exchange, physical adsorption. The modification intensifying these can promote immobilisation Finally, alleviates oxidative stress reduces tissues, thereby mitigating adverse development. Overall, our highlights capacity to remediate through diverse mechanisms, valuable insights sustainable remediation. Highlights Biochar mobility variety including limits its plants. Modified has been shown enhance effectiveness immobilising uranium. application not only promotes remediation but also improves quality. Graphical

Carboxymethyl Cellulose‐Based Composite Hydrogels for Sustainable Agriculture Under Drought Stress

Polymers for Advanced Technologies, Journal Year: 2025, Volume and Issue: 36(1)

Published: Jan. 1, 2025

ABSTRACT This study investigates the synthesis and characterization of a DAP‐loaded composite hydrogel comprising carboxymethyl cellulose‐g‐poly(acrylic acid‐acrylamide)/diatomite (CMC‐g‐P(AA‐AAm)/diatomite/DAP) using chemical crosslinking. The incorporation diatomite enhanced equilibrium water absorbency by 54.48% in distilled 34.02% tap water. demonstrated excellent reswelling capacity, maintaining 105.8 g/g 36.13 water, respectively, after 10 cycles. Soil treated with retained highest at 0.3% concentration, showing 291% increase 35°C compared to control. Composite treatments improved soil physiochemical properties, including bulk density, porosity, organic carbon, water‐holding microbial counts while reducing pH. facilitated controlled release nitrogen phosphorus, following Fickian diffusion. Enhanced germination rates mustard plant growth under drought conditions were observed, indicating potential sustainable agriculture. Further research field trials are required evaluate its performance diverse climate conditions, paving way for widespread adoption.

Bioconversion of organic orange peel wastes into compost (OPC) or biochar (OPB) can help overcome the effects soil salinity and maintain agricultural productivity. Effect 1.0% OPC OPB as amendments on properties performance Phaseolus vulgaris plants under two levels [5.60 dS m−1 (S-1) 9.60 (S-2)] versus control [1.60 (S-0)] was investigated. Compared to control, S-1 S-2 increased sodium ion (Na+) content, while reducing matter (OM), macro- micro-nutrients, cation exchange capacity (CEC), enzyme (urease, acid phosphatase, alkaline phosphatase) activities, reflecting decreased plant growth yield. Under S-2, application exceeded application, but both considerably enhanced OM nutrients, CEC, activities. These positive results reflected leaf electrolyte leakage leaf-relative water pigments, K+/Na+ ratio, antioxidant activity, growth, The beneficial impacts were more pronounced than S-0. In conclusion, adding saline (ECe about 5–10 m−1) could mitigate influences improve physio-biochemistry,
