Summary: In this study, the release behaviors and solid-liquid interface reactions of arsenic-containing iron minerals in simulated gastrointestinal bio-fluids were investigated. The results showed that goethite released 0.57 mg/L and hematite released 0.82 mg/L of arsenic, with bioaccessibility of 10.8% and 21.6% respectively. The release of arsenic was mainly coupled with acid dissolution and reductive dissolution of iron minerals, and proteases enhanced its mobilization. Calcium chloride reduced the bioaccessibility of arsenic, suggesting that calcium-rich food or drugs may be effective in reducing arsenic toxicity.

Summary: This study investigated the remediation of arsenic-contaminated abandoned mine soils. Oxalic acid was found to be the most effective washing reagent. Washing reduced the leachability and bioaccessibility of arsenic and iron in the treated soil, but it still exceeded the remediation criteria. Soil washing and subsequent solidification/stabilization could be an alternative option for remediating extremely contaminated abandoned mine soils.

Summary: A large amount of fish side streams are produced each year, causing significant economic and environmental issues. The study aimed to isolate high-value compounds from fish by-products and determine their effects on cell proliferation, as well as the influence of minerals and metals and the potential enhancement of cell proliferation by dietary antioxidants. The results showed negative effects on cell proliferation at high concentrations of hydrolyzed fish protein and collagen samples. However, pre-treatment with certain antioxidants increased cell proliferation. The highest mineral concentrations were found for P, Ca, and Mg, while metals appeared at almost undetectable levels in bioavailable fractions.

Summary: In this study, a dye pollutant (methyl orange) was effectively oxidized in a hydroxylamine-assisted Fenton system using various Al/Si/Fe- and Fe-containing minerals. The degradation kinetics of methyl orange were fastest in the olivine-HA Fenton system. The degradation rate constants were proportional to the dissolved Fe(II) quantities in the mineral suspensions, indicating the crucial role of dissolved Fe(II) quantity. Methyl orange was dominantly oxidized by center dot HO produced in the olivine-HA Fenton system. Lowering the pH resulted in the effective removal of methyl orange under various pH conditions.

Summary: In this study, a composite washing agent consisting of dithionite and tartaric acid was used to efficiently remediate arsenic-contaminated soils. The combination of these two compounds showed a synergistic effect, with dithionite promoting the dissolution of iron oxides and tartaric acid releasing some specifically adsorbed arsenic. The formation of Fe-TA complexes prevented the formation of new iron mineral phases and allowed for the release of more iron oxide-bound arsenic.

Summary: In this study, the effects of functionalized biochars (PBC and FePBC) and different irrigation regimes (CF and IF) on rice yield and the accumulation of As and Pb in rice grain were investigated. The results showed that FePBC increased rice yield under both CF and IF conditions. The concentration of As in grain was higher under CF conditions, whereas the concentration of Pb was higher under IF conditions. Therefore, the application of multiple-functionalized biochar can effectively increase rice yield and reduce As accumulation, particularly under IF conditions, but it is not applicable for Pb remediation in paddy soils.

Summary: Copper/carbon catalysts exhibit different pathways in peroxide activation depending on the electron-transfer regime, but the trigger for this transition is unclear. This study reveals that Cu species in sub-nanometre particles (SNPs) have an electrophilic nature, while Cu nanoclusters have a nucleophilic nature. The switch between nucleophile/electrophile nature leads to distinct catalytic mechanisms in activating peroxymonosulfate. The study demonstrates the regulable electroactive nature of carbon-supported Cu sites through scaling modulation and defect engineering.

Summary: Machine learning was used to predict the important factors affecting phytoextraction efficiency of hyperaccumulators. Heavy metal properties, especially the metal ion radius, were found to be the most important factors, while the plant family had the most influence on the bioconcentration factor, metal extraction ratio, and remediation time. The Crassulaceae family showed the highest potential as hyperaccumulators, related to gene expression and substance secretion. The insights from the machine learning model interpretation could guide efficient phytoremediation.

Summary: MW-assisted catalytic degradation of organic pollutants using Cu-loaded biochar catalysts showed high efficiency in the mineralization of refractory and high-concentration oxytetracycline. Reactive oxidizing species, which were barely detectable in a conventional heating system, played a crucial role in achieving the high efficiency in MW-assisted oxidation systems. The interactions between CuBC and MW were revealed by correlating the physiochemical characteristics to the MW absorption ability. These proposed catalytic systems have significant implications for the development of a high-throughput and low-carbon wastewater treatment technology.

Summary: This study investigated the interfacial transition zone (ITZ) in biochar-augmented carbon-negative cementitious materials using various analysis techniques. The results revealed significant changes in hydration degree and porosity at the edge of biochar. The integration of biochar and cement was mainly achieved through the formation of Ca-rich hydration products. In terms of mechanical behavior, biochar exhibited viscous-elastic deformation while hardened cement displayed plastic-elastic properties. The distinct differences in deformation contributed to the higher compressive strength of biochar-cement composites.

Summary: A PtNi/HT catalyst was prepared and used for glucose hydrogenation, achieving a high conversion rate of 95.7% and selectivity of 90.1% to polyols at 393 K in water. The catalyst demonstrated stability and recyclability for glucose conversion. Lower reaction temperatures favored hexitol production, while higher temperatures facilitated the generation of polyols with less carbon. The Pt delta--Ni delta+ pair on PtNi/HT played a crucial role in H2 activation and adsorption during glucose hydrogenation. The basic support of PtNi/HT efficiently catalyzed glucose isomerization and retro-aldol reaction in the aqueous phase.

Summary: In this study, the interaction between microplastics and biochar during environmental aging was investigated. It was found that early-stage interactions of microplastics and biochar could promote the release of dissolved organic matter (DOM) from biochar, while their long-term interactions resulted in the sorption of hydrophobic and small molecules of microbial byproduct-like DOM. Early-stage interactions also promoted the sorption of organic contaminants, but this promotion was no longer observed after aging due to the influence of heterogeneous aggregation.
