This study clarified the modulatory mechanisms by which foliar or root application of biosynthesized titanium oxide NPs (g-nTiO2) alleviated atrazine (ATZ) toxicity to Lactuca sativa L. Compared with the ATZ-alone group, 10 mg/L g-nTiO2 intensified light-harvesting, photoelectron transfer, and reduced oxidative damage, thereby improving growth and inducing metabolic reprogramming. Specifically, g-nTiO2 activated pathways related to energy supply and defense detoxification, while stabilizing membrane lipid and nitrogen metabolism. Furthermore, the modulation of biomarkers involved in balancing cellular homeostasis and stimulating growth by g-nTiO2 ultimately boosted lettuce resistance to ATZ and physiological performance. Molecular docking analysis revealed that g-nTiO2 enhanced the Phase II metabolism of ATZ by glutathione and amino acids through increasing detoxification enzyme activities by 23–44%, which confirmed the driving role of NPs in alleviating ATZ phytotoxicity to lettuce. Collectively, these findings provide a prospective nanoenabled strategy for mitigating crop sensitivity to pesticide residues for safe and sustainable agricultural production.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"9 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

A sustainable food waste management approach involves anaerobic codigestion with sewage sludge, enhancing biogas production while managing waste. Although this technology has been successfully tested, the biological mechanisms determining its efficiency are still poorly understood. This study leverages genome-scale metabolic modeling of 138 metagenome-assembled genomes to explore species interactions in lab-scale anaerobic reactors fed with sewage sludge to increasing proportions of food waste. The models showed positive correlations with experimental biogas production (CH4: r = 0.54, CO2: r = 0.66), validating their reliability. The dominant methanogen, Methanothrix sp., adapted its metabolism based on feedstock, affecting methane yields, which ranged from 2.5 to 3 mmol/g of volatile solids·h with sewage sludge to 10–14 mmol/g of VS·h with high food waste. The integration of extracellular enzymes into the models highlighted the role in methane production of pectin degradation, protein hydrolysis, and lipid metabolism, mediated by Proteiniphilum sp., Kiritimatiellae sp., and Olb16 sp. The study identified 475 mutualistic interactions involving amino acid, hydrogen, acetate, and phosphate exchange and 44 competitive interactions in hydrolytic and fermentative processes. These insights can help optimize anaerobic digestion and sustainable waste management in urban settings.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"71 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, conventional systems predominantly depend on costly ion exchange membranes, which are often plagued by fouling and scaling challenges. Here, we introduce an ingenious electrochemically assisted calcium silicate (EACS) system capable of achieving a rapid pH swing from 8.5 to 10 within 1 h through the in situ utilization of H+ and OH– ions, eliminating the need for membranes. The EACS system incorporates a novel 3D-printed porous basket holder designed to house calcium silicate particles and a rod-shaped Ru–Ir anode. Under closed-circuit conditions, the packed calcium silicate reacts with H+ generated at the anode, releasing Ca2+ into bulk solution, while OH– produced at the cathode accumulates, resulting in an elevated bulk pH. This mechanism enables the EACS system to achieve exceptional phosphorus recovery efficiency (88.4%–96.6%) from various waste streams, with energy consumption as low as 24.4 kWh kg P–1. Long-term continuous flow experiments demonstrate that periodic replacement of depleted silicate minerals sustains system efficiency and stability. Furthermore, comparative analysis reveals that while carbonate and silicate minerals are functionally viable, silicate minerals exhibit superior performance in removal kinetics, product purity, and reduced carbon emissions. Notably, the effluent from the EACS system, enriched with Ca2+ and characterized by a high pH, exhibits potential for direct air carbon capture. The proposed EACS system offers a transformative approach to environmental remediation and industrial applications, leveraging the fundamental principle of pH-swing to open new avenues for sustainable solutions.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"24 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Therefore the development of novel strategies to efficaciously control infectious inflammation is urgently required. Nuclear factor-κB (NF-κB) as the central activator of pro-inflammatory genes plays a pivotal role in infectious inflammation. Here, nanoscale chirality was designed to modulate the inflammatory response through enantiomer-dependent blockade of the NF-κB signaling pathway. Chiral gold nanoparticles (AuNPs) with good cytocompatibility were prepared through a one-pot seedless method under wild conditions, showing efficacious alleviation of lipopolysaccharide (LPS)-induced inflammation in vitro and in vivo only by AuNPs with levorotatory chirality (L-AuNPs) rather than the dextrorotatory enantiomer (D-AuNPs). Mechanism investigation elucidated that lysosomal acidification of macrophages was inhibited through a high cellular uptake of L-AuNPs due to their weak interaction energy with cell membranes. Accordingly, the NF-κB rather than mitogen-activated protein kinase pathway was blocked by L-AuNPs through the selective inhibition of p65 phosphorylation, wherein the nuclear translocation of p65 was simultaneously depressed, so the secretion of pro-inflammatory mediators was reduced significantly. This study suggests that imparting chirality to nanoparticles can provide a novel protocol to efficaciously modulate health risks arising from infectious inflammation by improving the uptake of nanoparticles with anti-inflammatory activity.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"20 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study assessed the occurrence, removal, and risk for antimicrobial resistance (AMR) of 102 antimicrobial substances and selected transformation products (TPs) in wastewater effluent from 47 wastewater treatment plants (WWTPs) across Australia. Thirty-two antimicrobials and 13 TPs were detected, with 14 analytes occurring at >80% frequencies. Ampicillin, penicillin V, penicilloic V acid, fluconazole, and tazobactam M1 were observed with high median concentrations of >0.2 μg/L. Collectively, the WWTPs released 5.4 kg/day or 0.54 g/day/1000 inhabitants of antimicrobials/TPs into natural waters, with β-lactams, quinolones, nitroimidazoles/azoles, and sulfonamides comprising high volumes, which was correlated with the population’s socioeconomic statuses. Thirty-seven analytes were removed at rates >80% post-treatment, whereas quinolones, nitroimidazoles/azoles, lincosamides, and macrolide TPs were observed with poor removal efficiencies, which were affected by treatment processes and regional climate. Comparing measured concentrations with the predicted no-effect concentrations for AMR selection (PNECAMR), 7 antimicrobials exerted selection risk for resistant bacteria. Concerningly, ciprofloxacin posed medium/high risk in most of the assessed WWTPs. The accumulative effects of antimicrobial classes and certain TPs might further aggravate adverse impacts on AMR development. Our study provides insights into the presence and AMR implications of antimicrobials in treated wastewater, aiming to safeguard public health and ecosystems.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"34 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
