The combined system boosted the degradation efficiency of LEV from 77.8% to 97.5%, improved the reaction rate constant by 2.3 times, and reduced energy consumption by 64.5%. DBD/chlorine process was highly efficient for LEV degradation across a pH range of 3.3-10.8, with removal rates varying from 90.3% to 97.5%. The electron paramagnetic resonance and scavenging experiments demonstrated the generation of reactive oxygen species (ROS, including HO•, 1O2, and O2•-) and reactive chlorine species (RCS) in the DBD/chlorine system, with 1O2 in the nonradical pathway being crucial for LEV removal. Crucially, effective activation of chlorine not only encouraged the production of reactive species but also prevented the formation of disinfection by-products (DBPs), successfully controlling the ecotoxicity of the reaction system. DBD could activate chlorine to form chlorate and HO•, which in turn triggered the production of RCS. The comparison of the LEV degradation pathway was proposed with or without chlorine in the DBD process. Finally, the effects of different water quality and water bodies demonstrated the application prospects of the DBD/chlorine process. This work provided an efficient technique for the elimination of antibiotics by non-thermal plasma/chlorine.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123727"},"PeriodicalIF":8.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845455","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}

This study investigates saline groundwater (SGW) pumping as a remediation technique for ASWI through experimental and field-scale analyses in a layered aquifer system characterised by diminishing permeability with depth. Experiments demonstrated that higher permeability layers reduced length of intrusion (Ltoe) whereas lower permeability layers restricted vertical displacement. The SGW pumping would be effective for gentler gradient and could be achieved by positioning the SGW wells at a distance of approximately one-third distance between the freshwater well and the coastal boundary. This hypothesis was tested by applying it to a layered case study with real aquifer settings with comparable conductivity anisotropy. Field study results confirmed the hypothesis, but cumulative impact of pumping rates and SGW well positioning showed smaller wedge penetration than experimentation due to higher field scale dispersion, resulting in optimal location within one-fourth of the distance. Diverging saddle points explain this phenomenon, which is necessary to provide a pulling force greater than freshwater abstraction. In contrast, an aquifer with passive saltwater intrusion location of wells should be near the shoreline to direct the hydraulic gradient towards the seawater boundary. Simulation results suggested that SGW pumping rates should be three to four times freshwater pumping rates to maximise Ltoe reduction. The findings from this study will aid in determining the optimal locations for placing subsurface intake wells for desalination operations in an aquifer that is impacted by ASWI.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123747"},"PeriodicalIF":8.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845421","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, previous studies have rarely addressed how varying degrees of vegetation degradation affect soil net nitrogen mineralization rates and their temporal dynamics in these sensitive ecosystems. Therefore, we conducted a three-year field-based soil core in situ incubation mineralization experiment on the northeastern margin of the Tibetan Plateau from 2019 to 2021 to assess the variations in soil net ammonification, nitrification, and mineralization rates during the growing season (June to October). The main aim was to determine the dynamic effects of different degrees of vegetation degradation (non-degraded, lightly degraded, moderately degraded, and severely degraded) on soil net nitrogen transformation processes, as well as the impact of seasonal fluctuations in soil temperature and moisture on net nitrogen mineralization. Results indicated that vegetation degradation significantly reduced the net ammonification rate by 22.09%-97.10%, significantly increased the net nitrification rate by 45.38%, and significantly decreased the net mineralization rate by 9.49%-16.25%. Redundancy analysis (RDA) and random forest models revealed the supportive role of soil water content in the soil nitrogen transformation processes, particularly in promoting nitrification, while soil temperature was identified as a positive regulator of N cycling enzyme activity, indirectly affecting net nitrogen mineralization rates.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123668"},"PeriodicalIF":8.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845491","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}

The model accounts for the heterogeneity of industrial structures and ownership attributes, examining both national aggregates and the adjustment paths and ownership trends across different provinces.

This study focuses on the cosmopolitan cold-water coral (CWC) Desmophyllum dianthus using ecological niche models (ENMs) to explore climate adaptation and conservation strategies. The findings indicated that D. dianthus occupied a broad ecological niche but had low ecological niche overlap across populations, suggesting local adaptations and supporting population-level ENMs. The models predicted that over 80% of D. dianthus suitable habitats would persist under SSP1-2.6 and SSP5-8.5 climate scenarios by the 2100s, potentially increasing to 95% as new habitats emerge, demonstrating its robust adaptability. However, localized environmental shifts could precipitate habitat losses in areas like the Reykjanes Ridge, Rockall Plateau, Mediterranean Sea, and Patagonian Shelf. We also applied Linkage Mapper to identify potential ecological corridors that intertwined nearshore macrohabitat patches with deep-sea stepping-stone habitats such as escarpments, seamounts, and ridges, maintaining population connectivity. Despite this, the habitats and ecological corridors of D. dianthus remained largely unprotected, with vulnerable portions lying outside of marine protected areas (MPAs), thus underscoring the urgent need for more MPA. These spatial-temporal predictions provide essential insights for the conservation and management of cosmopolitan CWC D. dianthus and serve as a benchmark for the adaptive survival of similar taxa.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123674"},"PeriodicalIF":8.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845403","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}

We focus on economic institutions because institutions that espouse economic freedom are essential for safeguarding environmental quality. We hypothesize that the spatial influence of these institutions varies both globally and regionally. The Moran's I test reveals significant spatial associations among countries, while the Wald and likelihood tests identify the spatial Durbin model as the most appropriate approach. Furthermore, the Hausman test indicates that a fixed effects model best captures the coefficients. Globally, economic institutions demonstrate a direct reduction effect of 16.4% and a spillover reduction effect of 4.4% on ecological footprint. However, these effects show considerable regional variation. In North America, East Asia and the Pacific, the Middle East, North Africa, Europe, and Central Asia, economic institutions effectively reduce ecological footprint, while their impact is negligible in other regions. These regional differences underscore the importance of addressing institutional deficiencies, encouraging policymakers in regions with limited effects to learn from best practices to enhance institutional effectiveness. These insights collectively advance the literature on economic institutions and environmental economics, emphasizing regional policy adaptation and the transboundary effects of institutional quality. The findings further reveal that economic institutions moderate GDP per capita to curb ecological footprint significantly. These conclusions hold even after addressing endogeneity using the generalized spatial two-stage least squares method. The study recommends that policies promoting economic freedom are essential to mitigate global environmental degradation.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123645"},"PeriodicalIF":8.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845476","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}
