Summary: This study investigates the competitive adsorption of mixed volatile organic compounds (VOCs) on biochar, showing that competition for sorption sites leads to a decrease in individual species' sorption capacity while maintaining the overall sorption capacity. Chemical interactions through hydrogen bonds, electrostatic attraction, and pore-filling are found to be the main mechanisms of VOC adsorption on biochar. Additionally, biochar regeneration efficiency is between 88% and 96%, indicating potential formation of permanent bonds during the sorption process.

Summary: Magnetite-functionalized biochar has the potential to be used for remediation of antibiotic-contaminated fields. This study investigated the sorption mechanisms of sulfonamide antibiotics on this engineered material and found that the sorption capacities and affinities varied with the properties of the antibiotics. Co-pyrolysis with Fe3+ enhanced the sorption performance of biochar, and the dominant sorption mechanism was H-bonding or pi-bond assisted H-bonding. The contributions of oxygen-containing groups instead of minerals were found to dominate the H-bonding energies.

Summary: The study found that the removal rate of NH4+-N in biogas slurry was consistently higher in the CWs under different dilution ratios, while the removal rates of TP, COD, and As showed an initial increase followed by a decrease with higher dilution ratios. The addition of zeolite and biochar enhanced the decontamination effect of CWs, with zeolite showing better removal of NH4+-N, TP, and COD, and biochar showing better removal of As. The enrichment and absorption of As by sediments, water spinach, and purple Pennisetum sinese were increased by adding biochar and zeolite, with zeolite having a more significant effect than biochar.

Summary: Iron-modified biochar (Fe-BC) prepared in this study showed enhanced adsorption capability for copper and sulfadiazine compared to pristine biochar (BC). The iron modification enlarged the surface area and loaded iron oxide nanoparticles on biochar surface, improving the adsorption efficiency. In the binary-pollutants system, there was a synergistic effect on the adsorption of Cu2+ and SDZ, possibly due to mutual bridging effects and complexation between the two pollutants. Fe-BC700 exhibited better removal efficiency for Cu2+ and SDZ in the binary system compared to single systems.

Summary: Misuse and overuse of antibiotics have led to the rise of antimicrobial resistance. In agricultural soils, antibiotics and antibiotic resistance genes (ARGs) are mostly found due to the application of livestock and organic wastes. Cattle manure, chicken manure, swine manure, and sewage sludge are the primary sources of antibiotics and ARGs in agricultural soils. Sulfonamides, tetracyclines, fluoroquinolones, and corresponding ARGs are the major types of pollution. Land-use type, soil, and climatic factors affect the concentrations of antibiotics and abundances of ARGs. Mobile genetic elements (MGEs), especially the sul1 gene, play a vital role in promoting the dissemination of ARGs. Better management of antibiotic and ARG contamination in agricultural soils is important for human health.

Summary: Recent studies have found that land serves as the most important sink for microplastics (MPs), but little is known about the photoaging processes of land surface MPs exposed to air. This study developed two spectroscopic methods to investigate the effect of air humidity on MP photoaging. The results showed that humidity significantly influenced the surface oxygen-containing moieties of MPs generated from photo-oxidation, especially for PVC-MPs. The study also revealed the RH dependence of coexisting contaminants' adsorption on photoaged MPs, which could be attributed to the varied hydrogen bonding between the contaminants and aged MP surfaces.

Summary: Oil pollution in water is a global issue that requires an efficient method for separating oil-water mixtures. We developed a sustainable method using functionalized organic waste. We created superhydrophobic SiO2 nanoparticle-fabricated spent coffee grounds (SSD-SCGs) that rapidly adsorb various oils in water, including crude oil, with high removal efficiency. The SSD-SCGs can effectively separate oil-water emulsions and can be easily regenerated, and even converted into a fuel source, achieving the goal of waste-to-energy conversion. This study demonstrates the potential of using agricultural waste to address multiple challenges related to sustainable development.

Summary: Research on machine learning (ML)-aided investigations for the removal of heavy metals (HMs) from contaminated waters has shown great potential. This approach offers the opportunity to optimize physiochemical processes and gain deeper insights into HM removal behaviors. However, challenges such as limited data availability, data formatting inconsistencies, and data collection inefficiencies need to be addressed. To overcome these challenges, centralized and decentralized data sharing methodologies should be promoted to accelerate ML-guided strategies for HM removal.

Summary: An integrated strategy of 3D architecture design and chemical doping shows great potential in improving the performance of bio-based engineered carbon materials in environmental applications. This review paper critically examines the use of bio-based IHPC with integrated hierarchical porous structures as engineered catalysts and adsorbents for environmental purposes. The hierarchically interconnected pore architectures reduce electrical resistance and shorten diffusion pathways, facilitating ion and molecule transport. The high pore volume, large specific surface area, and abundant active sites contribute to high capacity for ion and molecule capture. Chemical doping creates functional groups and active sites on the bio-based IHPC surface, enhancing its reaction and interaction capabilities with pollutants. The paper demonstrates the efficiency of bio-based IHPC in various environmental applications, such as removing toxic trace elements and pollutants, carbon capture, enhancing anaerobic digestion, antimicrobial treatment, and oil-water separation. The influence mechanisms of pore architectures and chemical doping on the performance of bio-based IHPC are thoroughly discussed. Promising research directions for the preparation and application of bio-based IHPC are also presented.
