Applying nano-delivery systems for phytohormones via foliar application has proven effective in reducing grain cadmium (Cd) levels in crops. However, the mechanisms underlying this reduction remain inadequately understood. This study integrated the determination of leaf photosynthetic parameters, Cd translocation analysis, and metabolomics to elucidate the effects of reduced glutathione (GSH) and melatonin (MT), delivered with or without chitosan-encapsulated mesoporous silica nanoparticles (MSN-CS), on grain Cd levels in rice. Our findings revealed that the foliar application of MT@MSN-CS significantly outperformed MT alone in reducing grain Cd levels and enhancing leaf photosynthesis under Cd stress. Conversely, GSH@MSN-CS showed comparable effects to GSH alone. Foliar-applied GSH@MSN-CS and MT@MSN-CS both decreased the Cd transport coefficients from panicle nodes to brown rice by 26.2–53.3%, with MT@MSN-CS demonstrating superior efficiency in reducing Cd concentrations across roots, stems, leaves, panicle nodes, and grains. Metabolomic analysis revealed substantial shifts in rice metabolite profiles following GSH@MSN-CS and MT@MSN-CS treatments. Foliar application of MT@MSN-CS or GSH@MSN-CS may rapidly and effectively activate the primary antioxidant defense system and alleviate membrane lipid peroxidation in rice grown on low-to-moderately Cd-contaminated soils by upregulating amino acid metabolism. The secondary defense mechanism, phenylpropanoid biosynthesis, was reprogrammed to reduce energy expenditure and decrease Cd translocation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

作者： Zhang, Qihang Ruan, Shiting Zhang, Ruiqian Zhashiquzong, Z. Wu, Weixiang Institute of Environment Pollution Control and Treatment College of Environmental and Resource Sciences Zhejiang University No. 866 Yuhangtang Road Hangzhou310058 China Zhejiang Province Key Laboratory for Water Pollution Control and Environmental Safety Technology Hangzhou310058 China Deqin County Bureau of Agriculture and Rural Affairs Rural Environment and Energy Service Station Diqing Tibetan Autonomous Prefecture674500 China

Utilization of perishable waste has emerged as the pivotal factor in enhancing the quality and efficiency of garbage classification in rural regions of China. Nevertheless, the operation of small-scale decentralized aerobic biological treatment facilities in rural areas will inevitably result in the emission of malodorous volatile organic compounds (VOCs). In this study, VOCs emission characteristics of three typical decentralized facilities for the treatment of perishable waste in rural areas were investigated using cold trap enrichment combined with gas chromatography and mass spectrometry to elucidate the characteristics and potential effects on environment and human health. The concentration range of different points in the mechanical composting (MC) treatment mode is from 43.555 to 4154.281 (mean value, 947.292) µg/m3, in the solar-assisted composting (SAC) it is from 99.050 to 2064.308 (636.170) µg/m3, and in the bioconversion by black soldier fly larvae (BBSF) it is 93.712 to 718.644 (283.444) µg/m3. Odor nuisance analysis showed that oxygenated compounds and aromatic compounds were the main odoriferous VOCs. Among all detected VOCs, o-xylene, toluene, and acrolein have the highest ozone formation potential (OFP). Toluene, ethyl benzene, and xylene are the VOCs with secondary organic aerosol generation potential (SOAP). Health risk analysis revealed that six VOCs collectively represent a potential carcinogenic risk, while acrolein exhibits a non-carcinogenic risk. In light of the odor nuisance, environmental impact, and potential health risk, the priority-controlled VOCs identified in decentralized aerobic treatment modes of rural perishable waste were acrolein, benzyl chloride, ethyl acetate, etc. The findings of this research can serve as a valuable reference for the selection of proper strategies in the precise control of VOCs. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

Elucidating the microbial mechanisms that trigger Fusarium wilt represents a key step in addressing the barriers to sustainable cropping. However,from the perspective of the complete microbiome, the integrated role of soil nutrients and microbial community in the fields with different rates of wilt disease remains unclear. In this study, we examined the potential interrelationships among the nutrients, bacteria, fungi, and protists in rhizospheric soils collected from the fields with watermelon cropping for 7 years at the Zhuanghang Experimental Station of Shanghai Academy of Agricultural Sciences,China. The soils collected were characterized by a high(HW, 81.25%) or low(LW, 6.25%) wilting rate. The HW soil was found to contain a higher abundance of Fusarium oxysporum(1.30-fold higher) than the LW soil, along with higher contents of available phosphorus(1.31-fold higher) and available potassium(2.39-fold higher). In addition, the interkingdom correlation between protists and bacteria in the HW soil was 2.08-fold higher than that in the LW ***, structural equation modeling revealed that an excess of soil available potassium enhanced the predation by potentially detrimental phagotrophic protists on potentially beneficial bacteria. In summary, our findings indicated that a balanced nutrient input and the interactions between protists(Cercomonas and Colpoda) and beneficial bacteria(Bacillus) played important roles in controlling the incidence of watermelon Fusarium wilt.

A 24-h pre-biodrying phase was introduced in 10-d double-phase biodrying-enhanced composting (BEC) to accelerate the humification of kitchen waste by promoting the generation of phenolic-rich aromatic skeletons, key humic precursors for the lignin-protein and polyphenol pathways. To explore how biodrying promotes phenolic hydroxyl accumulation, macromolecule decomposition, particularly lignin, was investigated. Compared to day 9 of 15-d conventional bioaugmented mechanical composting (BMC) without pre-biodrying, BEC achieved 78.32 ± 15.96 % higher lignin degradation by day 9 (p −1). Microbial analysis further revealed that oxygen availability, improved by frequent stirring and aeration during biodrying, enriched Bacillaceae and Issatchenkia, which accelerated bioheat generation and created thermophilic conditions favorable for Bacillus and Saccharomonospora capable of lignin demethoxylation (via vanAB, ligM) and β-O-4 cleavage (via ligD, ligL, ligE, ligF, ligG). High temperatures also enhanced microbial cooperation, enabling the lignin degraders to obtain nutrients, cofactors, and detoxification agents for basal metabolism and lignin degradation from Oceanobacillus, Gracilibacillus, Sinibacillus, Georgenia, Nigrospora, and Aspergillus, thereby reducing their metabolic burden and allowing them to focus on lignin degradation. This study is the first to unveil the humification mechanism during composting from the perspective of macromolecule decomposition, especially lignin, for the generation of phenolic-rich aromatic skeletons as key humic precursors, providing theoretical support for developing simple, effective strategies to accelerate composting. © 2025 Elsevier Ltd

A CN-supported Mn3O4 (Mn3O4-CN) composite was synthesized as a catalyst for the catalytic ozonation of 2,3-dimethylpyrazine degradation in wastewater. The catalytic efficiencies of 2, 3-dimethylpyrazine were investigated under various ozone dosages, catalyst dosages, pH and temperature conditions. The results showed that under the conditions of an ozone dosage of 3mg/L, a catalyst dosage of 0.02g/L, pH =7 and a temperature of 10°C, the degradation rate of pollutants reached 100% within 20 min. Scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction and other characterization methods were used to analyze the properties of the prepared Mn3O4-CN. It was confirmed that Mn3O4 and CN were successfully bonded, and the valence states of Mn were mostly +2 and +3. The reactive oxygen species analysis demonstrated that the surface hydroxyl groups and oxygen vacancies were identified as the main active sites, and .OH was the main active oxygen species generated in the reaction system. The cyclic experiments showed that the Mn3O4-CN has good stability and reusability. © 2025 Chinese Society for environmental Sciences. All rights reserved.

Cyclodextrin metal-organic framework (CD-MOF) with environmentally friendly components has attracted enormous attention in the past few decades. However, the fragile aqueous stability has limited its application in aqueous catalysis. In this work, we have devised a novel strategy to cope with the problems by introducing the well-defined gold nanoclusters (AuNCs) onto the cyclodextrin ligand through host-guest chemistry. The combination with AuNCs endowed the fragile CD-MOF with excellent multi-enzyme mimicking catalytic abilities, including peroxidase (POD), oxidase (OXD), catalase (CAT) and glucose oxidase (GOx)-mimetic activities. Furthermore, based on its intrinsic POD-like activities, by constructing the typical enzyme cascade reaction, a colorimetric sensor based on Au38/γ-CD-MOF was developed for the rapid and sensitive of carbaryl and butyrylcholinesterase (BChE) activity, respectively. In addition, combined with the smartphone, a portable paper-based sensor was developed, which could realize the on-site and semiquantitative detection of pesticide residues by identifying the RGB value. This low-cost and easy-operation portable assay shows great potential for online detection of pesticides exposure and monitoring other disease biomarkers. © 2025 Elsevier B.V.
