Herein, a delignified wood-derived carbon embedded with nitrogen (DLWC@N) was designed to enhance peroxymonosulfate (PMS) activation for the degradation of aqueous ciprofloxacin (CIP). The removal of lignin and hemicellulose in poplar wood was found to facilitate the formation of a more porous architecture and tailed the permeability of channels in the carbon. N species and N content were regulated on this hydrophilic cellulose skeleton through a simple pyrolysis strategy. The resulting DLWC@N-700 achieved 97.49% CIP removal within 60 min and exhibited 79.64 % removal efficiency after four consecutive cycles. The unique three-dimensional network structure in the derived carbon promoted the diffusion of the solution and exposed much more active sites. Graphitic N and N-O bonds as main active sites during PMS activation were revealed. The quenching experiments combined with electron paramagnetic resonance and electrochemical analysis unveiled that the degradation process was dominated by a non-radical pathway of singlet oxygen and electron transfer. Liquid chromatography-mass spectrometer results demonstrated that the main degradation pathway of CIP included hydroxylation, cleavage of the piperazine ring, and cyclopropane shedding, resulting in the formation of seventeen reaction intermediates.

The results indicated that bacterioferritin is widely distributed among the genera Jettenia, Brocadia, Kuenenia, and Scalindua. Using two bacterioferritins (K.S Bfr and Q1Q315) from Candidatus. Kuenenia stuttgartiensis, engineered E. coli strains expressing these proteins exhibited higher survival and preserved cellular integrity under 10 mM H₂O₂ stress compared with the wild-type bacteria (WB). In vitro experiments confirmed that bacterioferritin acts as a reactive oxygen species scavenger by eliminating H₂O₂ through iron oxidation at its ferroxidase center. Furthermore, it was found that the gene abundances of K.S Bfr and Q1Q315 increased.in anammox granules exposed to H₂O₂. Proteomic analysis revealed notable damage to membrane- and DNA-associated proteins in WB under H₂O₂ stress, accompanied by significant upregulation of conventional antioxidant proteins. However, this response was insufficient to protect WB from high concentrations of H₂O₂. In contrast, engineered bacteria showed a significant upregulation of ribosomal metabolic pathways, enhancing intracellular protein synthesis, particularly of K.S Bfr and Q1Q315. These proteins mediated reactions that consumed H₂O₂, thereby providing a crucial buffer period for cellular ribosomal activity.

However, the effects of pesticides on pollinator foraging behavior remain inconsistent. We studied whether buff-tailed bumblebees (Bombus terrestris) visited plants exposed to glyphosate-based herbicides (GBH) when non-contaminated plants were available. Additionally, we examined whether oral exposure to GBH and the presence of an invasive plant (Lupinus polyphyllus) influenced bumblebee foraging behavior. Our findings revealed that bumblebees visited recently GBH-treated plants in both field and flight cage experiments. Furthermore, bumblebees did not discriminate between GBH-treated and uncontaminated plants when the choice was based solely on the plant's emitted volatile compounds, which changed slightly after exposure. Oral GBH treatment reduced the foraging activity of bumblebees; a higher proportion of exposed bumblebees compared to control bees did not visit any plants. Nevertheless, in the presence of the plant invader, control bees visited fewer plants than GBH-exposed bees.

Projections were made for two age groups (<65 and ≥65 years) using five climate models under three greenhouse gas (GHG) emission scenarios aligned with shared socio-economic pathways (SSP1-RCP2.6, SSP2-RCP4.5, and SSP5-RCP8.5) across three time periods: base year (1995-2014), mid-21^st century (2031-2050), and end of the 21^st century (2081-2100). By the end of the 21^st century, in the absence of HA, the average heatstroke mortality rate (HMR; cases per population) in Japan is projected to increase 4.26- and 3.63-fold for the <65-year and ≥65-year groups, respectively, relative to the base year, under all climate models and GHG scenarios. With HA, these increases were reduced to 1.76- and 1.49-fold for the <65-year and ≥65-year groups, respectively.

The influence of geological background and sedimentary environment of watershed on spatial distribution of PTEs in sediments of alluvial delta is of great significance for prevention and control of soil PTEs pollutions in river delta. Research on it should still to be emphasized. This study took Pearl River Delta (PRD) as study area, sediment bores samples were collected from 10 points in different sub-watershed provenance and river delta. Discriminant analysis, principal component analysis and Pearson correlation analysis were utilized to investigate influences of watershed characteristic and sediment depositional environment on PTEs concentrations in sediments. The results show that sediment of bores from different sub-watershed provenances exhibit distinct geochemical characteristics which could reflect geological background in upper reaches of different sub-watersheds. Sediments carried by different rivers were constrained to their own low stand valleys and provided little opportunity for mixing between sources. PTEs of sediment in bores from delta area are principally controlled by provenance factors. Carbonate rocks, black rock series and polymetallic deposits are primary sources of PTEs in sediment of bores from delta area. Sedimentary environment constrains horizonal distribution patterns of PTEs of sediments in different bores. PTEs are enriched in silty and mucky clay strata of sediments formed by land-sea interaction. Drastic changes in hydrodynamic and chemical conditions are the main reasons for PTEs enrichment in sediments in terrestrial sedimentary and offshore sedimentary environment.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"123015"},"PeriodicalIF":7.7,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145231211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the low reactivity of gold tailings and the associated heavy metals may hinder hydration and compromise the mechanical and environmental performance of such systems. In this study, a super-sulfated cement (SSC) system incorporating gold tailings was developed and modified with lithium slag. The hydration behavior, strength development, pore structure evolution, and heavy metal immobilization performance were systematically investigated through multi-scale characterization. The results showed that the incorporation of 20 % gold tailings led to a notable reduction in compressive strength (up to 34.83 % at 7 days) due to the presence of inert minerals and hydration inhibitors. However, the replacement of 10 % gold tailings with lithium slag significantly enhanced strength at all ages, refined the pore structure, and increased the formation of C-S-H and ettringite (AFt). Thermogravimetric and calorimetric analyses confirmed that lithium slag accelerated hydration and increased the content of chemically bound water. SEM-EDS analysis revealed that heavy metals including As, V, and Mn were effectively immobilized within AFt and C-S-H matrices.

Despite extensive research, the factors influencing the severity of bronchiolitis remain poorly understood. Environmental factors, including exposure to particulate matter (PM) with diameters ≤10 μm (PM₁₀) and ≤2.5 μm (PM_2.5), are suspected of exacerbating RSV bronchiolitis by enhancing inflammatory pathways. We previously demonstrated that PM₁₀ and PM_2.5 levels during the three weeks preceding pediatric emergency department admission (the -3rd week AVG) are associated with increased bronchiolitis severity in infants. The bacterial nasal microbiota (bNM), lying at the interface between the environment and the airways, has emerged as a key modulator of host immune and inflammatory responses, potentially influencing the pathogenesis and course of bronchiolitis in response to environmental triggers. This study examines the effects of PM₁₀ and PM_2.5 on bNM composition in the context of bronchiolitis and explores the role of bacterial extracellular vesicles (bEVs) as potential modulators of inflammatory processes after PM exposure, using a zebrafish model to monitor the inflammatory response in vivo. We conducted a case-control study involving 110 infants diagnosed with bronchiolitis (cases) and 49 matched healthy controls (HC), revealing significant differences in bNM composition between cases and HC. The -3rd week average (AVG) of PM exposure influenced the bNM, with cases showing a higher relative abundance of Haemophilus influenzae (Hi), becoming more pronounced as PM levels increased. Injection of Hi-derived bEVs into zebrafish embryos induced a robust pro-inflammatory response, characterized by neutrophil recruitment and upregulation of inflammatory gene expression. Our findings reveal that air pollution alters bNM composition, potentially worsening bronchiolitis in infants through inflammatory processes.
