Carbohydrates are essential nutrients that serve as primary energy sources and structural components in living organisms. However, excessive consumption of conventional sugars has been increasingly linked to global health burdens such as obesity, diabetes, and metabolic disorders, as well as environmental concerns including greenhouse gas emissions. d-Tagatose, a naturally occurring rare sugar, has attracted considerable attention due to its low caloric value, prebiotic effects, and anti-obesity and anti-diabetic properties. Recent breakthroughs in targeted chemo-enzymatic synthesis, combined with directed evolution and systems metabolic engineering, have enabled more efficient and scalable production routes. Concurrently, the valorization of agricultural and food processing wastes as alternative raw materials aligns with circular bioeconomy principles and enhances sustainability. This review provides a comprehensive overview of recent technical advances, benefits, and ongoing challenges in d-tagatose production. We also highlight emerging strategies to facilitate commercialization and position d-tagatose as a cornerstone of the next generation of health-promoting sweeteners.

The accumulation of nitrates in water bodies caused by human activities poses a serious threat to human health and aquatic ecosystems. Electrocatalytic nitrate reduction reaction (eNO3RR), as a promising green process, can convert nitrate (NO3−) into high-value ammonia (NH3), achieving the goal of “turning waste into resources”. However, eNO3RR is a significantly complex process involving multiple influencing factors. Herein, we critically review the fundamental principles of NO3− reduction and selective NH3 synthesis in eNO3RR. The cathode engineering design for the NH3 generation by eNO3RR is systematically summarized, including a comparative analysis of precursor materials, such as precious metals, transition metals, and nonmetals. Moreover, the critical roles of reactor configuration, initial NO3- concentration, pH conditions, and competitive ions in determining the selectivity and yield of NH3 from NO3− reduction are thoroughly analyzed. This review also evaluates the research on efficient and compatible ammonia recovery technologies, addressing the core post-reaction processing gap in the field. Finally, techno-economic assessments and key challenges of eNO3RR are synthesized to examine the industrial potential and further implementation prospects.

A life cycle assessment (LCA) was conducted to evaluate the carbon footprint and resource efficiency of recycling straw waste into building materials. Three straw valorization pathways—straw resin-bonded particleboard (SRBP), straw cement-bonded particleboard (SCBP), and straw-based supplementary cementitious material (SCM)—were assessed and compared with the prevailing practice of straw open burning (SOB). Environmental and economic performance was evaluated in terms of greenhouse gas (GHG) emissions, global warming potential (GWP), non-renewable energy consumption, resource expenditure, and cost–carbon synergy indices. The assessment adopts a dual-dimensional framework, combining horizontal comparison among straw management scenarios with vertical benchmarking against conventional wood-based particleboards. Methodological novelty is further achieved by integrating a cost–carbon synergy index with a one-million-iteration Monte Carlo simulation to jointly quantify economic–environmental performance and uncertainty, and by grounding the analysis in region-specific industrial data from Jilin Province to support policy-relevant conclusions. Results show that SCM exhibits the lowest carbon footprint (273.18 kg CO2eq per ton of straw), whereas SOB produces the highest emissions (2834.80 kg CO2eq/t). Relative to conventional wood-based boards, SRBP and SCBP reduce GHG emissions by 9.90 % and 4.53 %, respectively, while lowering non-renewable energy demand by up to 3.08 % and 14.88 %. SCM achieves the largest emission mitigation potential, with a unit abatement cost of 0.072 CNY per kg CO2eq, substantially below representative social carbon cost thresholds, whereas SRBP and SCBP achieve positive cost–carbon synergy without direct fiscal support. Sensitivity analysis identifies transportation distance and molding electricity as dominant GWP drivers, and Monte Carlo simulation confirms the robustness of scenario ranking under parameter uncertainty. Overall, SRBP and SCBP offer economically viable pathways with synergistic emission reductions, while SCM provides substantial climate benefits through deep emission mitigation. These findings support targeted promotion of straw-based particleboards and the development of carbon-trading mechanisms for SCM, alongside logistics optimization and process-level emission reduction strategies.
采用生命周期评价方法（LCA）评价了秸秆废弃物资源化利用的碳足迹和资源效率。对秸秆树脂粘接刨花板（SRBP）、秸秆水泥粘接刨花板（SCBP）和秸秆基补充胶凝材料（SCM）三种秸秆增值途径进行了评估，并与秸秆露天焚烧（SOB）的普遍做法进行了比较。从温室气体（GHG）排放、全球变暖潜势（GWP）、不可再生能源消耗、资源支出和成本-碳协同指数等方面对环境和经济绩效进行了评价。该评估采用了双重框架，将秸秆管理方案的横向比较与传统木质刨花板的纵向基准相结合。通过将成本-碳协同指数与100万次蒙特卡罗模拟相结合，共同量化经济-环境绩效和不确定性，并以吉林省特定地区的工业数据为基础进行分析，以支持与政策相关的结论，进一步实现了方法上的新颖性。结果表明，SCM的碳足迹最低（每吨秸秆273.18 kg CO2eq），而SOB的碳排放量最高（2834.80 kg CO2eq/t）。与传统的人造板相比，SRBP和SCBP分别减少了9.90%和4.53%的温室气体排放，同时降低了3.08%和14.88%的不可再生能源需求。供应链管理实现了最大的减排潜力，单位减排成本为每千克二氧化碳当量0.072元人民币，大大低于代表性的社会碳成本阈值，而SRBP和SCBP在没有直接财政支持的情况下实现了积极的成本-碳协同效应。敏感性分析表明运输距离和成型电力是GWP的主要驱动因素，蒙特卡罗仿真验证了参数不确定性下情景排序的鲁棒性。总体而言，SRBP和SCBP提供了经济上可行的协同减排途径，而SCM通过深度减排提供了实质性的气候效益。这些发现支持有针对性地推广秸秆刨花板和发展供应链管理的碳交易机制，以及物流优化和过程级减排战略。

Per- and polyfluoroalkyl substances (PFAS) persistently challenge conventional water treatment technologies, particularly for short-chain species. This study develops an innovative electro-nanofiltration (E-NF) process that synergistically couples a direct current electric field with nanofiltration to enhance PFAS removal. Systematic investigation reveals that a forward-aligned electric field reduces PFOA permeation flux by 75.2% compared to conventional NF, primarily via electrophoretic migration. Under optimal conditions (11.1-13.3 V·cm⁻¹), the process achieves high rejection of PFOA (90.4%) and PFBS (83.9%) with competitive energy consumption below 1.92 kWh·m⁻³ under optimal conditions. We identify a critical hydraulic threshold at 0.8 MPa, beyond which concentration polarization dominates and leads to chain length-dependent rejection collapse. A modified solution-diffusion-electromigration model quantitatively decouples the transport mechanisms, determining higher apparent electrophoretic mobility for PFBS than for PFOA. The E-NF system demonstrates excellent reversibility and stability, confirming its potential as a robust and energy-efficient solution for mitigating PFAS contamination.

Air Pollution Control (APC) residues deriving from acid gas (HCl, HF, SO2) removal processes are typically disposed of in hazardous waste landfills. This study explores the potential reuse of these residues as alternative CO2 sorbents in the Calcium Looping process, leveraging their content of unreacted lime. APC residues originating from different industrial sources (waste-to-energy, ceramic, and glass plants) were subjected to multiple carbonation–calcination cycles and benchmarked against a reference hydrated lime. The observed performance was linked to the morphological and compositional variability of the residues. Ceramic APC residues exhibited an inverse correlation between CO2 uptake and the presence of stable fluorinated and sulfated phases. The monotonic decline in CO2 carrying capacity upon cycling was ascribed to sintering. Waste-to-energy residues displayed a more complex cyclic behavior, associated with the melting of chlorinated phases under calcination conditions and the consequent rearrangement of product layers on sorbent particles. Despite their lower performance compared to virgin hydrated lime, APC residues achieved up to 140 mg CO2/g sorbent after 10 cycles.

Dams are vital for water resource security and energy supply, yet they present a significant challenge to terrestrial ecosystems. Most existing studies focus on a single region, lacking comprehensive analysis of the impacts of various types of dams on land use and land cover change (LULC) and landscape patterns as well as their gradient effects at a global scale. This study systematically analyzed the impact of global dams on the surrounding environment within 5-km gradient buffer zones, utilizing data from 6763 dams constructed between 1984 and 2018 in the Global Dam Tracker (GDAT) and the GLC_FCS30D global 30 m LULC data (1985–2020), alongside land use dynamics and landscape pattern indices. The results showed that from 1984 to 2018, new dams were primarily built in developing countries in Asia (3277 dams) and Africa (2079 dams) in the last 35 years. The majority of these dams were built for irrigation (32%) and hydroelectric power (20%). The construction of these dams resulted in a 120% increase in impervious surfaces and a 6% deforestation rate within the 5-km buffer zone, and the integrated land use dynamicity in the near-dam zone (0–2 km) was significantly higher than in the far-dam zone. Among them, irrigation dams exhibited the steepest distance decay rates, indicating the strongest impact on the surrounding land-use dynamics. After 1995, there was an increase in landscape fragmentation (patch density (PD)) and Shannon’s diversity index (SHDI) increased, while the aggregation index (AI) and mean patch area (AREA_MN) decreased. Our study provides a reference base for assessing the ecological effects of dams and managing them sustainably around the world.
大坝对水资源安全和能源供应至关重要，但对陆地生态系统构成了重大挑战。现有研究大多集中在单一区域，缺乏在全球尺度上对各类水坝对土地利用和土地覆盖变化（LULC）、景观格局的影响及其梯度效应的综合分析。本研究利用全球水坝追踪系统（GDAT）和GLC_FCS30D全球30 m LULC数据（1985-2020）中1984 - 2018年间建成的6763座水坝的数据，以及土地利用动态和景观格局指数，系统分析了全球水坝对5公里梯度缓冲区内周边环境的影响。结果表明，从1984年到2018年，在过去的35年里，新水坝主要建在亚洲（3277座水坝）和非洲（2079座水坝）的发展中国家。这些水坝大部分用于灌溉（32%）和水力发电（20%）。这些水坝的建设导致5 km缓冲区内不透水地表面积增加120%，森林砍伐率增加6%，近坝区（0-2 km）的综合土地利用动态显著高于远坝区。其中，灌溉坝的距离衰减速率最大，对周边土地利用动态影响最大。1995年以后，景观破碎化程度（斑块密度）增加，Shannon多样性指数（SHDI）增加，聚集指数（AI）和平均斑块面积（AREA_MN）减少。本研究为世界范围内大坝生态效应评估和可持续管理提供了参考依据。

Background
Air pollution is associated with poor health, including chronic diseases, cognitive declines, and physical limitations in late life. The financial burdens of these exposures are likely underestimated due to a reliance on indirect estimates not generated by individual-level data and the exclusion of out-of-pocket expenses and long-term care costs.
Methods
We used repeated measures of Medicare-linked survey data from respondents in the Health and Retirement Study (HRS), a nationally-representative, population-based, cohort study in the United States. We included all respondents aged ≥ 67 years who were enrolled in fee-for-service coverage between 2006 and 2016 to characterize associations between air pollution and Medicare and out-of-pocket healthcare spending. We estimated 10-year average concentrations of four key air pollutants (PM2.5, PM10-2.5, NO2, O3) for each respondent using residential histories and spatiotemporal models. We summarized Medicare and out-of-pocket (OOP) spending ($2016) for medical services, personal services, and prescription drugs for each respondent per month. Associations between 10-year average air pollution and monthly healthcare spending were assessed per interquartile range of exposure using linear and quantile regression, adjusting for confounding and accounting for survey design.
Results
Among 11,160 respondents (72 ± 7yrs), the mean annual total healthcare spending in Medicare and out-of-pocket spending were $16,680 and $3,156, respectively. Higher levels of PM10-2.5 and NO2 were associated with upward shifts in annual healthcare spending with $614 (95% CI: $324, $904) and $1,047 (95% CI: $580, $1,515) higher spending at the 90th percentile and $138 (95% CI: $113, $163) and $162 (95% CI: $123, $201) higher median spending, respectively. In contrast, associations with PM2.5 were not robust to the adjustment of co-pollutants, and O3 was associated with lower spending.
Conclusion
Interventions to reduce PM10-2.5 and NO2 may mitigate societal and personal healthcare spending for older adults, particularly for those with high medical needs.

We estimated 10-year average concentrations of four key air pollutants (PM<sub>2.5</sub>, PM<sub>10-2.5</sub>, NO<sub>2</sub>, O<sub>3</sub>) for each respondent using residential histories and spatiotemporal models. We summarized Medicare and out-of-pocket (OOP) spending ($2016) for medical services, personal services, and prescription drugs for each respondent per month. Associations between 10-year average air pollution and monthly healthcare spending were assessed per interquartile range of exposure using linear and quantile regression, adjusting for confounding and accounting for survey design.<h3>Results</h3>Among 11,160 respondents (72 ± 7yrs), the mean annual total healthcare spending in Medicare and out-of-pocket spending were $16,680 and $3,156, respectively. Higher levels of PM<sub>10-2.5</sub> and NO<sub>2</sub> were associated with upward shifts in annual healthcare spending with $614 (95% CI: $324, $904) and $1,047 (95% CI: $580, $1,515) higher spending at the 90th percentile and $138 (95% CI: $113, $163) and $162 (95% CI: $123, $201) higher median spending, respectively. In contrast, associations with PM<sub>2.5</sub> were not robust to the adjustment of co-pollutants, and O<sub>3</sub> was associated with lower spending.<h3>Conclusion</h3>Interventions to reduce PM<sub>10-2.5</sub> and NO<sub>2</sub> may mitigate societal and personal healthcare spending for older adults, particularly for those with high medical needs.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"1 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115962","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}

The United Nations' 2030 Agenda for Sustainable Development emphasizes conserving marine resources, making sustainable ocean economies a global priority. Coastal cities, critical hubs for marine-terrestrial systems, face dual pressures: driving growth and managing climate risks. This research examines how urban environmental resilience facilitates the sustainable marine economic development of coastal cities. Using data from 51 Chinese coastal cities spanning 2007 to 2022, the research constructs multidimensional indices for Marine Economy-Society Comprehensive Benefit Index and Environmental Resilience. To analyze the relationships, a two-way fixed-effects model is utilized. The analysis reveals that environmental resilience enhances the sustainable marine economic development, and with the mediating role of Foreign Direct Investment. Results demonstrate a nonlinear threshold effect: resilience significantly boosts sustainability in medium-resilience cities but yields diminishing returns in high-resilience regions. Regional heterogeneity is evident, with southern cities benefiting more due to export-oriented economies and disaster exposure, while northern cities face structural constraints. By integrating environmental and sustainable metrics, this research offers new insights into the resilience-sustainability linkages, enriches coastal studies with threshold and mediation frameworks, and provides actionable foundations for policymakers to tailor development strategies to local capacities.

This study investigates the performance and environmental impact of a 100% recycled EN 45500 aluminum alloy subjected to T6 heat treatment, using its primary counterpart as a benchmark. Both alloys were produced by gravity die casting under controlled laboratory conditions and subsequently characterized from a microstructural and mechanical standpoint. The recycled alloy exhibited a higher iron content, promoting the formation of Fe-based intermetallic compounds, which increased defect density and reduced ductility compared to the primary alloy. Heat treatment parameters were optimized to balance mechanical performance with energy efficiency. Tensile testing revealed that the recycled alloy achieved mechanical properties comparable to those of the peak-aged primary alloy when aged at 160 °C for 4.5 h, a less energy-intensive condition than the 180 °C for 4.5 h required by the primary alloy. The environmental impact analysis demonstrated a significant reduction in carbon footprint, from 19.6 kgCO2eq/kgAl for the primary alloy to 2.47 kgCO2eq/kgAl for the recycled one. For 100% recycled EN 45500 alloy, the heat treatment, including solution treatment and aging, accounted for 92.3% of CO2eq emissions, underscoring the relevance of heat treatment optimization. Overaging tests demonstrated that the recycled EN 45500 retained copper-driven thermal stability. Overall, the findings highlight the capability of recycled aluminum to meet both mechanical performance and sustainability requirements to produce advanced automotive applications.
