1. {"_":"Revisiting the UV/permanganate process: HO and overlooked triplet-state intermediates drive benzoate derivative degradation.","sub":["222"],"sup":["•"]}
PMID:日期:2026-09-24The UV KrCl* excimer lamp outperforms traditional UV lamp in advanced oxidation processes (AOPs) due to higher photon energy, improved oxidant activation, and environmental safety. While previous studies primarily ascribed contaminant degradation in UV/permanganate to HO and reactive manganese species (RMnS), the role of substrate excited states remains largely underexplored. Here, we revisited benzoate derivative degradation mechanism in the UV/permanganate process by elucidating the origins of HO and the contribution of triplet-state benzoates. The degradation kinetics of terephthalic acid (TA) and 2-hydroxyterephthalic acid (2HTA) in UV/permanganate were 2.1 -7.3 times higher than UV/permanganate. Both HO and triplet benzoate derivatives contributed to their degradation. HO originated primarily from HO (67.9%) and permanganate (22.5%). Meanwhile, triplet-state TA (TA*) and 2HTA (2HTA*) reacted rapidly with permanganate at second-order rate constants (k) of 2.2 × 10 and 5.5 × 10 M⁻s⁻, respectively, followed by reactions of secondary intermediates (2HTA and e). Triplet-state-related pathways contributed 36.3% to 2HTA removal, and their roles were promoted under N purging. Even treating simulated drinking water, the synergistic effect of UV and permanganate was still significant. This study clarifies a novel degradation mechanism for benzoate derivative degradation in the UV/permanganate process, emphasizing the overlooked roles of triplet benzoate derivatives.

2. Pulmonary-route-dominant retention and exposure burden of biodegradable PLA microplastics: Radiotracer-based toxicokinetics and development of the TRACE exposure-response framework.
PMID:日期:2026-09-23Despite the growing adoption of polylactic acid (PLA) as a biodegradable alternative to conventional plastics, its biological fate following human exposure remains poorly defined. No study has systematically compared the toxicokinetics of PLA microplastics (MPs) across inhalation and oral exposure routes within a unified experimental framework. Here, we developed a radiotracer-based platform combining I radiolabeling and high-resolution SPECT/CT imaging to quantify route-dependent biodistribution and clearance kinetics of PLA MPs in mice. Intratracheal administration produced greater and more persistent tissue burdens than oral administration, with prolonged pulmonary retention, systemic redistribution, and a 2.25-fold higher blood area under the curve. To systematically link organ-level exposure burden with cellular biological response, we developed the TRACE (Toxicological Response And Cellular Exposure) framework, comprising five indices (TRACE-M, -C, -E, -R, -I) spanning mitochondrial injury, oxidative stress, and exposure-linked toxicity. TRACE-based analyses revealed stronger oxidative and ultrastructural stress responses in lung-derived cellular models than in gastrointestinal systems. Human exposure contextualization via allometric scaling and time-dependent mass-balance modeling further indicated that repeated inhalation may drive progressive pulmonary PLA accumulation under environmentally plausible conditions. Together, these findings establish inhalation as the dominant hazard route for PLA MPs and demonstrate that biodegradability does not confer biological safety.

3. Multi-source data fusion for precision prevention and control of groundwater pollution in industrial brownfields.
PMID:日期:2026-09-23Groundwater contamination at industrial brownfields is governed by interacting sources, hydrogeochemical processes, aquifer structures, and land-use context, making concentration-based assessment insufficient. We developed a data-driven, multi-source fusion framework based on latent class analysis for a large Chinese industrial brownfield. Using 379 monitoring wells, the framework integrated land-use patterns (L), hydrogeochemical patterns (H), groundwater vulnerability (V), contaminant mobility (M), and comprehensive pollution grade (P) to delineate prevention-and-control zones via statistical clustering. Mn and NH₃-N were the principal contaminants. The area was divided into five management zones: key monitoring (15.14%), protection and conservation (23.89%), transitional control (25.87%), critical control (15.73%), and urgent remediation (19.37%). Key monitoring zones exhibited low pollution but high mobility and vulnerability. Transitional zones faced mixed land-use pressures. Critical control zones require migration interception, while urgent remediation zones demand immediate containment and targeted remediation. By integrating contaminant occurrence, migration risk, environmental sensitivity, and management demand, this framework shifts groundwater risk assessment from identifying pollution intensity toward formulating differentiated control strategies.

4. Breaking kinetic limitations in Fenton-like processes: Freezing- enhanced activation of peracetic acid by ultra-low Mn(II) dosage for micropollutants degradation.
PMID:日期:2026-09-23Peracetic acid (PAA)-based Fenton-like systems have attracted considerable attention as promising advanced oxidation processes (AOPs) for water purification. However, the homogeneous activation of PAA by Mn(II), a widely employed transition metal, remains intrinsically inefficient under conventional conditions. In this study, we propose a novel cryogenic strategy that enables highly efficient activation of PAA by Mn(II) even at ultralow dosages. Notably, at neutral pH, the frozen PAA/Mn(II) system exhibited a 146.4-fold enhancement in the pseudo-first-order rate constant for sulfamethoxazole (SMX) degradation relative to that under ambient conditions. Mechanistic investigations revealed that high-valent manganese species predominated as the reactive intermediates under freezing conditions. Furthermore, theoretical calculations demonstrated that the ice-water interface promotes the localized enrichment of reactants while substantially reducing the critical activation energy barriers, thereby synergistically accelerating the Fenton-like reaction kinetics. A first-principles-based kinetic model quantitatively captured the temporal evolution of manganese species, identifying Mn(V) as the dominant reactive species in the frozen system. In addition, bicarbonate ions were found to further enhance SMX removal, and the frozen system exhibited robustness in complex aqueous matrices. Collectively, this work presents a compelling strategy for boosting PAA-based Fenton-like reactivity and establishes a new conceptual framework for water remediation under cold and freezing conditions.

6. Bioaccumulation, trophic transfer and exuvial elimination of polystyrene nanoplastics in a terrestrial predator-prey system.
PMID:日期:2026-09-22Despite the ubiquitous spread of nanoplastics, their trophic transfer and biological impacts in terrestrial ecosystems remain poorly understood. Here, europium-labelled 100 nm polystyrene nanoparticles (Eu-PS-NPs) were used as a tracer to investigate their accumulation, trophic transfer, and sublethal effects along a terrestrial predator-prey interaction involving larvae of carabid beetle Carabus lefebvrei and the snail Cantareus aspersus. Inductively coupled plasma mass spectrometry demonstrated significant accumulation in beetle larvae fed contaminated snails (0.01 and 0.1% w/w). Trophic transfer factors remained below 1, indicating no biomagnification. Eu-PS-NPs were mainly retained within the larval digestive tract (0.013 ± 0.004 and 0.072 ± 0.006 µg g in the 0.01% and 0.10% Eu-PS-NP group, respectively), whereas lower concentrations were detected in larval gut-free tissues (0.0033 ± 0.0005 and 0.011 ± 0.004 µg g, respectively). They were also detected in exuviae (0.049 ± 0.019 and 0.171 ± 0.022 µg g, respectively), suggesting ecdysis as a potential overlooked elimination pathway. Although survival was unaffected, significant sublethal effects, including reduced moulting rate and altered phenoloxidase activity, indicated developmental and immune modulation. These findings demonstrate that dietary nanoplastic exposure induces measurable physiological stress in terrestrial predators despite the absence of biomagnification. This study advances understanding of nanoplastic dynamics in terrestrial food webs and highlights the role of ecdysis in regulating particle burdens.

7. Suppression of arsenic trioxide dissolution by antimony substitution.
PMID:日期:2026-09-22Roasting arsenopyrite during gold production generates hazardous arsenic trioxide roaster waste (ATRW). At the Giant Mine, Canada, > 20,000 tonnes ATRW were aerially dispersed while another 237,000 tonnes are buried. Arsenolite [AsO] largely comprises ATRW, but minor elements may have substantial geochemical influence (e.g. Fe, Sb, Ca). To investigate controls on ATRW dissolution, we performed batch experiments on variable-composition Giant Mine samples. Following two weeks of anoxic reaction (21 and 4 ˚C), AsO dissolution (17.9 and 12.3 g L) only reached 72% and 73% of AsO solubility Up to a 27% decrease in dissolution was attributed to increased Sb:As weight ratios. Ionic strength (0.02 M NaCl, 0.20 M NaCl) and starting pH (4, 6, 8) differences resulted in < 5% variation in dissolution. X-ray absorption spectroscopy (XAS) identified no substantial As/Sb bonding differences between consistently trivalent pre- and post-dissolution solids. Pair distribution function (PDF) and automated mineralogy results support XAS modelling, indicating an increased abundance of As-Sb bonding compared to initial solids. Therefore, Sb may be predominantly locked in a persistent AsO-SbO solid-solution, where residue may remain stable following management-related dissolution of ATRW. Selective As dissolution increases relative concentrations of residual Au and Sb, and redistribute the risks associated with wastes.

8. A sustainable hydrometallurgical recovery strategy of critical metals from spent NCM via aspartame-assisted reductive leaching: Mechanism, stepwise recovery process and LCA.
PMID:日期:2026-09-22Inspired by the use of aspartame in sugar-free food additives, this study developed an aspartame-assisted reductive leaching process for the efficient dissolution of critical metals from spent NCM batteries. The speciation of the critical metals under different pH conditions was theoretically investigated, and the reductive leaching behavior was optimized using single-factor experiments and response surface methodology. Under optimized conditions (NCM-aspartame mass ratio 1:1.1, 65 °C, and 1.3 M HSO), the leaching efficiencies of critical metals exceeded 99%.More importantly, mechanistic investigations revealed that methanol generated during aspartame hydrolysis reduced high-valence transition-metal ions to soluble divalent species. Together with proton attack, this reduction promoted the collapse of the layered NCM structure. Leaching kinetic analysis further demonstrated that the process was controlled by surface chemical reactions. Furthermore, a stepwise recovery process was developed, in which Ni was first separated through selective chelation, Co and Mn were subsequently co-extracted, and Li was finally recovered by carbonate precipitation. The purities of all recovered products exceeded 98.5%. Besides, techno-economic analysis and life-cycle assessment demonstrated the economic feasibility and favorable environmental performance of the process, aiming to provide a sustainable hydrometallurgical strategy for the efficient recovery of critical metals from spent NCM batteries.

9. Long-term developmental alterations in intestinal microbiota, metabolism, and T-cell homeostasis in offspring rats following maternal tetrabromobisphenol A exposure.
PMID:日期:2026-09-22Tetrabromobisphenol A (TBBPA), a widely used brominated flame retardant, has been associated with adverse health effects. An exploratory NHANES analysis of urinary bisphenol A (BPA) was performed to provide general population-level context for bisphenol-related metabolic and inflammatory associations because urinary TBBPA measurements were unavailable. We investigated whether maternal TBBPA exposure (170 mg·kg⁻¹·day⁻¹) was associated with developmental alterations in offspring intestinal homeostasis. Maternal TBBPA exposure was associated with colonic inflammatory features, increased pro-inflammatory cytokine expression, and reduced Treg/Th17 ratios in F1 offspring. Gut microbiota composition was altered, including phylum- and genus-level differences, accompanied by altered fecal short-chain fatty acid composition and concentrations. Exploratory untargeted metabolomics identified nominally altered MS/MS-supported putatively annotated metabolite features. Primary bile acid biosynthesis had the lowest raw pathway-level p value and was therefore considered the top-ranked exploratory pathway, although no pathway remained significant after pathway-level FDR correction. Collectively, maternal TBBPA exposure was associated with developmental alterations in gut microbiota composition, microbial metabolites, fecal metabolic profiles, and intestinal T-cell homeostasis in F1 offspring, providing insight into the potential developmental intestinal immunotoxicity of TBBPA.

10. Moss crust microhabitats promote bacterial community convergence via homogeneous selection under multimetal contamination in restoring bauxite mines.
PMID:日期:2026-09-21Moss crusts are important ecosystem engineers in degraded mining lands, yet their role in regulating bacterial community assembly under metal contamination remains poorly understood. This study compared moss crust soil, underlying soil, and adjacent bare soil in a karst bauxite mine restoration area. Moss crusts significantly altered the distribution of multiple metals and promoted coordinated multimetal enrichment in moss-associated habitats, likely via upward capillary transport and biological adsorption. Compared with bare soils, moss crusts significantly increased bacterial richness, phylogenetic diversity, and community evenness. Moss-associated communities also showed markedly reduced spatial variability and stronger compositional consistency across sampling sites, indicating pronounced community convergence. Moss crusts selectively enriched bacterial groups associated with nutrient cycling and environmental adaptation, including Actinobacteriota, Bacteroidota, and Pseudomonadota, while maintaining clear vertical niche differentiation between crust and underlying layers. Bacterial community assembly shifted from heterogeneous selection in bare soils to homogeneous selection in moss-associated habitats. Multiple metals (Mg, Al, Mn, Zn, and Fe) were the primary factors influencing community structure and dynamics, overriding conventional soil properties (pH, EC, TP, and AP). By promoting homogeneous ecological selection under metal contamination, moss crusts stabilize microbial communities and may represent an effective nature-based strategy for restoring degraded bauxite mining ecosystems.
