However, no reliable scientific reports have documented its abiotic dechlorination using Fe(0). In our study, we investigated the reaction between endosulfan and Fe(0) and found that endosulfan does not undergo reductive dehalogenation. Instead, it is hydrolyzed to yield equimolar quantities of endosulfan diol. This finding was verified using analytical methods, including GC–MS, IR and NMR, on the tentatively collected reaction product and by comparison with data for standard endosulfan diol. Iron oxide on the surface of Fe(0) we used was Fe₃O₄, which was verified by the XPS and Raman analysis. Acid-washed Fe(0) without Fe₃O₄ coating on the surface of Fe(0) could not hydrolyze endosulfan, nor could Fe₃O₄ alone without Fe(0), indicating that the combined roles of Fe(0) and the Fe₃O₄ coating are important. In contrast to previous studies showing alkaline hydrolysis of endosulfan at high pH, our results indicate that no hydrolysis occurred at pH 11 in the absence of Fe(0) over 48 h. Approximately 98% of the loss of endosulfan was accounted for by the hydrolytic formation of endosulfan diol, which was subsequently decomposed by Fe(0). This research provides the first evidence that Fe(0) and Fe₃O₄ on the surface of Fe(0) work together to create an alternative pathway for the breakdown of organochlorine pollutants.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In urban centers, CO₂ diffusion is often hindered by the complex-built environment, impairing carbon transfer from sources like buildings to sinks such as green spaces and reducing overall sequestration efficiency. Therefore, quantifying the influence of building layouts on CO₂ diffusion in central urban areas is crucial for fostering low-carbon communities and formulating urban planning strategies for climate change mitigation and adaptation. This study develops a methodological framework to explore how the form and layout of residential buildings in urban centers affect CO₂ dispersion. Taking Hangzhou as a case study, the spatial distribution of carbon emissions was first quantified via the IPCC inventory method. High carbon-emitting residential districts in central Hangzhou were then selected as study sites. Subsequently, a coupled WRF-HYSPLIT model was employed to simulate the trajectory paths and residence times of CO₂ diffusion under varying residential building heights, forms, and spacings. Finally, the relationship between building layout configurations and CO₂ diffusion mechanisms was examined, leading to the formulation of corresponding control measures and renewal strategies. Results indicate that: (1) building heights exceeding 36 m significantly obstruct CO₂ diffusion, with no further increase in hindrance beyond 80 m; (2) point-type buildings facilitate better diffusion than slab-type forms, with 36 m and 80 m point-type structures outperforming those at 54 m; and (3) under similar floor area ratios, high-rise layouts with larger building spacings demonstrated superior CO₂ diffusion compared to low-rise, closely spaced arrangements. This study offers empirical insights for optimizing residential building layouts to enhance urban carbon diffusion efficiency, contributing to China’s “Dual Carbon” strategy in urban design and renewal.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Those strong C–F bond formations justify the applicability of PFAS as a strong performer across industrial applications, due to their comprehensive properties, including resistance to water, heat, and chemicals, which lead to gradual accumulation and cause adverse health impacts. The complex behavior of PFAS in soil with different physicochemical characteristics has resulted in a lack of studies that utilize the molecular-level behavior in soil for further modelling purposes, which is important for a strong foundation for remediation measures. Therefore, this study focuses on elucidating theoretical, novel descriptions to fulfill the above-identified requirements. The developed paradigm, “Hydrophobically Driven Paradigm”, explains the strong attachment of PFAS to soil and the building of the PFAS-soil interface, employing the soil–water partitioning coefficient for clay soil from the literature. After confirming the strong attachment of PFAS to soil particles, the molecular-level interactions between PFAS and soil particles were explained by the framework, “System Retention Framework,” based on PFAS Zeta Potential (ZP) calculations derived under electrokinetic principles to describe the molecular-level retention behavior of PFAS. ZP values for two long-chain and short-chain PFAS were calculated using Henry’s and Nernst-Einstein equations. Results highlight that PFAS with higher ZP values have higher retention, while lower ZP values exhibit lower retention, in soil, confirming that the paradigm and framework can be used to define charge-driven interactions, followed by hydrophobically energized strong attractions, which are readily available for describing PFAS molecular-level behavior for future modelling with system contaminants.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"23 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 aims to investigate the removal of levofloxacin by the Advanced Oxidation Process (AOP) in a heterogeneous system of iron-loaded porous carbon from sugar palm fiber (Fe/SPF-C). Sugar palm fiber, a byproduct of the starch industry, is an abundant precursor for the production of porous carbon. Porous carbon was prepared through pyrolysis and followed by an activation process using gaseous CO₂. Iron oxide was then loaded onto porous carbon by wet impregnation at various %-wt loadings. Several characterizations of N₂-sorption, SEM–EDX, and FTIR were used to reveal the properties of the catalyst, such as specific surface area, pore distribution, morphological structures, iron oxide distribution, and functional groups. The results showed that increasing the Fe loading to 6% did not significantly alter the catalyst structure or pore distribution. The adsorption of levofloxacin showed the best fit with the Langmuir isotherm and the pseudo-second-order kinetic model, with a maximum adsorption capacity of 39.8 mg/g.
