This study was aimed to analysis the degradation kinetics of nitrobenzene and aniline by the Fe-N/BC redox system. Factors such as the initial pH of the solution, PMS/NaBH4 concentrations, and pollutant concentrations were investigated to explore the variations in pollutant degradation rates in the system. The results indicated that the Fe-N/BC-catalyzed NaBH4 reduction of nitrobenzene followed first-order kinetics, while the Fe-N/BC-catalyzed PMS oxidation of aniline followed pseudo-first-order kinetics. When the pH was alkaline, the reaction was inhibited. Increasing the addition of NaBH4 and PMS from 0.05 to 0.5 g/L resulted in the reaction rate constants for nitrobenzene and aniline increasing from 0.115, 0.120 min-1 to 0.743, 0.354 min-1, respectively. As the pollutant concentration gradually rose from 2 to 50 mg/L, the reactions were inhibited, with the reaction kinetics for nitrobenzene and aniline decreasing from 0.348, 0.288 min-1 to 0.147, 0.091 min-1, respectively. © Published under licence by IOP Publishing Ltd.

2024 6th International Conference on Advanced Materials and Ecological Environment, AMEE 2024

This study was aimed to optimize the preparation conditions of Fe-N/BC catalyst. Citric acid iron and melamine was used to co-doped modified selected biomass, optimized factors included biomass type, acid washing time, iron-nitrogen doping amount and pyrolysis temperature, with nitrobenzene as the targeted degradation object. The optimal preparation conditions for Fe-N/BC iron-nitrogen co-doped biochar catalyst were determined. The results showed that using onion as the biomass, after 8 hours of acid washing, immersed in an ultrasonic solution of citric acid iron with a concentration of 8 g/L for 30 minutes, followed by adding melamine at a doping ratio of 5 g/g biomass and another 30 minutes of ultrasonication, centrifuged, water washed, and dried, then pyrolyzed at 900°C under N2 atmosphere for 1 hour. The obtained Fe-N/BC iron-nitrogen co-doped biochar catalyst exhibited the best removal efficiency for nitrobenzene in a catalytic reduction system, with a removal rate of 96.6% after 15 minutes of reaction. © Published under licence by IOP Publishing Ltd.

In this study, the citric acid iron and melamine was used to modify the selected biomass, preparing Fe-N/BC iron-nitrogen co-doped biochar catalyst. The BC, N/BC, and Fe-N/BC were characterized by SEM, XRD, FTIR, Raman, XPS, etc., to research the aspects of micromorphology, crystal structure, surface functional group types, and element composition. The results showed that Fe and N elements could be doped into the biochar successfully, making the particle size of Fe-N/BC smaller than that of BC, possessing a bigger surface area with a more abundant pore structure. Additionally, the graphitization degree of Fe-N/BC was enhanced, introducing active sites including pyridinic nitrogen, graphitic nitrogen, and Fe-Nx, enhancing the catalytic activity and electron transfer performance of the catalyst, enabling Fe-N/BC to simultaneously act on catalytic reduction and catalytic oxidation systems. © Published under licence by IOP Publishing Ltd.

Pakistan, like many other regions around the world, is experiencing the impacts of climate change, particularly in its northern region. These changes have adverse impacts on ecosystems and biodiversity. Herein, we have investigated future projections of temperature and precipitation trends for three periods historical (HT = 1975–2005), near-term (NT = 2010–2029), and mid-term (MT = 2030–2050) using climate model intercomparison projects along with global climate models (GCMs) including RCP4.5 and RCP8.5. The historical records spanning from 1975 to 2005 reveal that the Chilas region has a notable rise of 8 °C in maximum temperature (Tmax), whereas the Astore district exhibited a trend of decreasing temperatures. When examining the projected temperature trends using GCMs (RCP4.5 and RCP8.5), the Chilas region is predicted to undergo a further increase of 6 °C in Tmax. In contrast, the Babusar region is projected to observe a significant decrease of 2 °C for the period between 2010 and 2050. Additionally, the precipitation results obtained from historical-based analysis for the period 1975 to 2005 indicated that the Babusar area exhibited increased precipitation patterns to 20 mm on an annual basis. Similarly, the Astore region has the most significant decline in precipitation, with a reduction of 40 mm annually. The predicted precipitation patterns for the period between 2010 and 2050 under the RCP8.5 revealed that the Babusar region has maximum precipitation (25 mm). Conversely, the Astore region exhibited reduced precipitation patterns, recording minimum precipitation (40 mm). In the results from RCP4.5, the precipitation showed a similar pattern with a maximum of 35 mm and a minimum of 15 mm in the Babusar and Astore, respectively. The region’s glaciers, snow cover, and land use systems are deteriorated by these changes in temperature and precipitation patterns. The increased winter and decreased summer precipitation under varied temperatures and precipitation cau

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.

As one of the main emerging contaminants, microplastics (MPs) have received extensive attention due to their profound impact on freshwater ecosystems, and biofilms are almost exposed to various water environments. In this study, mature biofilms were used as the research object to establish a indoor microecosystems and the experiments of exposure to polystyrene microplastics (PS-MPs) and polypropylene microplastics (PP-MPs) with different particle sizes lasting 7 days. The research findings indicated that PS-MPs exhibit a greater enrichment effect on biofilms compared to PP-MPs as well as a more pronounced impact on microbial community of biofilms. Furthermore, it has been observed that the number of PP-MPs and PS-MPs enriched by biofilms was negatively correlated with their particle size. The results obtained from high-throughput sequencing of 16S rRNA revealed an increased abundance of Bacteroidetes in biofilms exposed to PP-MPs, while the presence of PS-MPs leads to decreased abundance of Proteobacteria and Planctomycetes in biofilms. The attachment of PP-MPs induced alterations in the abundance of at least 30 % of the dominant bacterial genera within biofilms. The heightened presence of Hydrogenophaga could potentially augment the nitrogen cycling capability within biofilms, whereas the reduced prevalence of Rhodobacter might impede their ability to carbon cycle. Analysis conducted using data from the KEGG database unveiled that MPs accumulation led to modifications in metabolic pathways including those related to biofilm photosynthesis, carbon fixation in photosynthetic organisms. In conclusion, elucidating the interaction between MPs and biofilms can offer crucial theoretical insights for addressing MPs pollution. © 2025 Elsevier Ltd. All rights reserved.

The advent of large-scale mobile monitoring using fast-response instruments has enabled hyperlocal mapping (≤100 m) of traffic-related air pollution (TRAP), with important implications for air quality management. However, most related studies have been confined within small areas due to the high cost and labor intensity. This study pioneers a cost-effective TRAP mapping method by incorporating large-scale mobile monitoring and land-use machine learning (LUML). Here, over 4.6 million 1 Hz high-frequency measurements (∼1300 h) were collected on a part of major roadways in the Chinese megacity of shenzhen. Unmeasured locations were estimated by LUML models to reduce measurement costs and labor intensity. Various ML algorithms and varying spatial aggregation segment lengths were incorporated to optimize the model performance. Hyperlocal maps of NO, NO2, and PM2.5were predicted across the entire road network covering over 1700 km2. Based on our results, LU-RF (random forest) for mapping NO and NO2and LU-GBM (Gradient Boosting Machine) for mapping PM2.5, demonstrated superior performance. Deep learning models, in contrast, did not yield comparable results. Finer partitioning of road segments (≤100 m) improved NO prediction performance, but worsened that for NO2and PM2.5. By deployment of optimal ML algorithms and segment lengths, the TRAP mapping accuracy increased by 20–80% compared to conventional land-use regression models. This study provides a promising and cost-effective approach to hyperlocal air pollution mapping and management in cities worldwide.
