Coral reefs are one of the ecosystems that are most affected by climate change, but they also support biodiversity, coastal stability, fisheries, and tourism around the world. This review uses a structured narrative literature review based on PRISMA protocols to put together evidence from 220 peer-reviewed articles (1996 to 2025) to see how warming seas, ocean acidification, rising sea levels, and stronger storms change coral ecology, structure, and ecosystem functioning. The results indicate that heightened thermal stress is the principal catalyst of mass bleaching and mortality, occurring with greater frequency and at larger spatial scales, whereas ongoing acidification persists in diminishing calcification, skeletal density, and recruitment success. The rise in sea level and damage caused by storms make habitat loss happen even faster, make reefs less complex, and make communities of reef-associated species less stable. Even though things are going this way, new interventions like coral gardening, larval propagation, assisted evolution, marine protected areas, and community-led co-management show promise for making things more resilient in the face of future climate change. The review emphasizes the necessity of immediate global carbon reduction in conjunction with customized conservation and restoration strategies at the local level. If no strong action is taken, coral reefs may not last long, and the economic security they provide may also go down.

珊瑚礁是受气候变化影响最严重的生态系统之一，但它们也支持着世界各地的生物多样性、海岸稳定、渔业和旅游业。本综述采用基于PRISMA协议的结构化叙事文献综述，将220篇同行评议文章（1996年至2025年）的证据放在一起，以了解海洋变暖、海洋酸化、海平面上升和更强的风暴如何改变珊瑚生态、结构和生态系统功能。结果表明，热应力升高是大规模白化和死亡的主要催化剂，发生频率更高，空间尺度更大，而持续的酸化持续降低钙化、骨骼密度和招募成功率。海平面上升和风暴造成的破坏使栖息地丧失得更快，使珊瑚礁变得不那么复杂，使与珊瑚礁有关的物种群落变得不那么稳定。尽管事情正在朝着这个方向发展，但新的干预措施，如珊瑚园艺、幼虫繁殖、辅助进化、海洋保护区和社区主导的共同管理，表明了在面对未来气候变化时使事情更具弹性的希望。该报告强调，必须立即在全球范围内减少碳排放，并结合地方层面的定制保护和恢复战略。如果不采取强有力的行动，珊瑚礁可能不会长久，它们提供的经济保障也可能会下降。

Cosubstrate type is a key factor shaping decolorization behavior, while magnetite (Fe₃O₄) is recognized as an electron transfer facilitator in anaerobic dye treatment systems. This study elucidated how cosubstrate type and Fe₃O₄ jointly influence anaerobic azo dye decolorization through batch and continuous experiments. In batch tests, five cosubstrates were comparatively evaluated for their decolorization performance under Fe₃O₄-free and Fe₃O₄-amended conditions. Complex cosubstrates (glucose and starch) likely favored enzyme-associated azo reduction, whereas simpler cosubstrates (ethanol, acetate, and propionate) exhibited decolorization patterns consistent with enhanced extracellular electron transfer (EET), particularly in the presence of Fe₃O₄. Ethanol achieved 85–95% decolorization efficiency and was identified as the most effective cosubstrate-Fe₃O₄ combination. In continuous operation, ethanol maintained stable decolorization over 235 days, and Fe₃O₄ addition further enhanced performance by 15%. A methanogenic activity assay confirmed that the acetoclastic pathway remained stable, while conductive conditions likely enabled additional electron-utilization pathways, such as EET, allowing concurrent methane production and dye reduction. Microbial and predicted functional analyses revealed enrichment of putative EET-associated taxa (e.g., Geobacter, Desulfovibrio, Pseudomonas, Methanosarcina, and Methanobacterium). This shift was accompanied by increased abundances of EET-related genes (1.5–2.3-fold) and reduced abundances of azoreductase-related genes (1.6-fold), supporting a transition toward EET-associated decolorization under conductive conditions. These findings highlight the synergistic role of cosubstrate selection and conductive materials in regulating decolorization behavior, offering practical insights for optimizing anaerobic dye wastewater treatment.

共底物类型是影响脱色行为的关键因素，而磁铁矿（Fe3O4）在厌氧染料处理系统中被认为是一种电子转移促进剂。本研究通过批量和连续实验，阐明了共底物类型和Fe3O4对厌氧偶氮染料脱色的共同影响。在批量试验中，比较了5种共底物在不含fe3o4和添加fe3o4条件下的脱色性能。复杂的共底物（葡萄糖和淀粉）可能倾向于酶相关的偶氮还原，而简单的共底物（乙醇、醋酸酯和丙酸酯）表现出与增强的细胞外电子转移（EET）一致的脱色模式，特别是在Fe3O4存在时。乙醇的脱色效率为85 ~ 95%，是最有效的助底物- fe3o4组合。连续运行235天，乙醇保持稳定脱色，添加Fe3O4使脱色性能进一步提高15%。一项产甲烷活性分析证实，丙酮裂解途径保持稳定，而导电条件可能会产生额外的电子利用途径，如EET，从而同时产生甲烷和染料还原。微生物和预测功能分析显示，假定的eet相关分类群（例如，Geobacter, Desulfovibrio, Pseudomonas， Methanosarcina和Methanobacterium）富集。这种转变伴随着eet相关基因的丰度增加（1.5 - 2.3倍）和偶氮还原酶相关基因的丰度减少（1.6倍），支持在导电条件下向eet相关脱色过渡。这些发现强调了共底物选择和导电材料在调节脱色行为中的协同作用，为优化厌氧染料废水处理提供了实际见解。

Current water management frameworks are often disjointed, failing to consider the full range of potential water uses. This fragmentation leads to inconsistent regulations; for example, potable water production from wastewater often faces stricter quality standards than water sourced from even wastewater-impacted surface waters. This article proposes a use-based approach to water management, developing water quality standards that account for the economic, public health, and ecological needs of downstream users. We advocate for expanding the concept of water quality from simple pollutant removal to “building water” to match the needs of users, so desired constituents are either left in the source water or added to treated water to meet specific user needs. This strategy requires a multidimensional, risk-based regulatory framework, supported by advances in data science and affordable measurement tools for effective enforcement. Such advancement enables a move beyond binary standards to foster sustainable global water resource management and mitigate scarcity.

目前的水管理框架往往是脱节的，没有考虑到潜在用水的全部范围。这种碎片化导致监管不一致；例如，从废水中生产饮用水往往比从受废水影响的地表水中提取的水面临更严格的质量标准。本文提出了一种基于用途的水管理方法，制定水质标准，考虑下游用户的经济、公共卫生和生态需求。我们主张将水质的概念从单纯的去除污染物扩展到“建筑水”，以满足用户的需求，因此所需的成分要么留在源水中，要么添加到处理后的水中，以满足特定的用户需求。这一战略需要一个多维的、基于风险的监管框架，并得到数据科学进步和负担得起的衡量工具的支持，以实现有效的执法。这种进步使我们能够超越二元标准，促进可持续的全球水资源管理，缓解水资源短缺。

Ensuring sustainable soybean supply and consumption under climate change is critical for global food and environmental security. China, as the world's largest soybean consumer, exerts substantial influence on global land use, trade flows, and carbon emissions through its evolving supply and consumption patterns. This study applies a computable general equilibrium model combined with an environmentally extended input-output approach to quantify how climate change and adaptive policy measures affect China's soybean supply and consumption and further transmit to the global supply chain. The results reveal that external shocks and climate stressors jointly reduce China's soybean production by up to 4.83%. Enhancing domestic self-sufficiency alone cannot close the growing demand gap, which leads to import reductions of 1.32%–8.26%. However, climate change intensifies supply risks and increases reliance on major exporters, while raising their emissions. By 2060, China's imports from Brazil and the other Latin American regions are projected to rise by 2.13%–2.82% and 2.15%–3.76%, respectively, with embodied emissions increasing by 91.90 × 10³–124.28 × 10³ tCO₂ and 15.75 × 10³–27.08 × 10³ tCO₂. Production subsidies could boost domestic production by 5.89%, reduce imports by 3.55%, and lower emissions by 253.54 × 10³ tCO₂. Technological advancements can mitigate climate-induced production declines by 1.36%–9.13% globally, stabilize Chinas's soybean imports within −0.01%–0.08%, and reduce emissions by 4.78 × 10³–45.60 × 10³ tCO₂. These adaptive strategies provide actionable insights for improving the resilience of the soybean supply chain.

在气候变化条件下确保大豆的可持续供应和消费对全球粮食和环境安全至关重要。中国作为世界上最大的大豆消费国，通过其不断变化的供应和消费模式，对全球土地利用、贸易流动和碳排放产生了重大影响。本研究采用可计算一般均衡模型，结合环境扩展投入产出方法，量化了气候变化和适应性政策措施对中国大豆供应和消费的影响，并进一步传递到全球供应链。结果表明，外部冲击和气候压力因素共同导致中国大豆产量减少高达4.83%。仅靠提高国内自给自足并不能弥补日益扩大的需求缺口，这将导致进口减少1.32%-8.26%。然而，气候变化加剧了供应风险，增加了对主要出口国的依赖，同时增加了它们的排放量。预计到2060年，中国从巴西和其他拉美地区的进口量将分别增长2.13% ~ 2.82%和2.15% ~ 3.76%，隐含排放量将分别增加91.90 × 103 ~ 124.28 × 103 tCO2和15.75 × 103 ~ 27.08 × 103 tCO2。生产补贴可提高国内产量5.89%，减少进口3.55%，减少排放253.54 × 103 tCO2。技术进步可以缓解全球因气候变化导致的产量下降1.36%-9.13%，将中国大豆进口量稳定在- 0.01%-0.08%，并减少4.78 × 103 - 45.60 × 103吨二氧化碳的排放。这些适应性策略为提高大豆供应链的弹性提供了可行的见解。

Carbon emissions of the aviation sector are expected to double by 2050, and there is an urgent need to change the approach to product and system design to enable a sustainability transition. Through a systematic literature review, this paper analyses 51 studies and provides a comprehensive overview of the current state of sustainable product development in the design of aircraft systems and sub-systems. A taxonomy of challenges across six categories is proposed, ranging from socio-ecological issues, regulations, economic context, design process, cognitive barriers, and technological limitations. This taxonomy supports clarifying the nature of problems practitioners may encounter when implementing sustainable product development. While aerospace companies face systemic challenges, this study argues that they can overcome structural, human, and technical barriers. But to overcome this, sustainable product development capabilities need to be developed, which this study maps across product development phases and organisational levels. Fourteen aerospace-tailored support methods are reviewed through the lens of these capabilities, showing gaps in enabling cross-functional communication, managing trade-offs systematically, and mitigating sustainability risks. This study advances the field of Sustainable Product Development by offering a sector-specific synthesis of challenges, capabilities, and support methods in aerospace. The findings align with broader sustainability literature and provide a foundation for future cross-sectoral research and methodological development. Together, these contributions support aerospace practitioners in navigating sustainable product development challenges, developing critical capabilities, and calls for further research to accelerate sustainability integration in product development.

到2050年，航空业的碳排放量预计将翻一番，迫切需要改变产品和系统设计方法，以实现可持续转型。本文通过系统的文献综述，分析了51项研究，全面概述了飞机系统和子系统设计中可持续产品开发的现状。提出了六类挑战的分类，包括社会生态问题、法规、经济背景、设计过程、认知障碍和技术限制。这种分类法有助于澄清从业者在实施可持续产品开发时可能遇到的问题的性质。虽然航空航天公司面临着系统性挑战，但本研究认为，他们可以克服结构、人力和技术障碍。但为了克服这一点，需要开发可持续的产品开发能力，本研究将其映射到产品开发阶段和组织层面。通过这些能力对14种航空航天定制支持方法进行了审查，显示了在实现跨职能沟通、系统管理权衡和减轻可持续性风险方面的差距。本研究通过提供航空航天领域特定领域的挑战、能力和支持方法的综合，推进了可持续产品开发领域。研究结果与更广泛的可持续发展文献相一致，为未来的跨部门研究和方法发展奠定了基础。总之，这些贡献支持航空航天从业者应对可持续产品开发挑战，开发关键能力，并呼吁进一步研究以加速产品开发中的可持续性集成。

High groundwater nitrate associated with agricultural activity is a global environmental problem. However, linking spatial variability of groundwater nitrate and agricultural activity quantification needs to be elucidated. This paper seeks to explain the spatial variability of groundwater nitrate in the loess area of Tongchuan City, China, identify the contributing factors using hydrogeochemical and statistical methods, and analyze the connection between farmland leaching and groundwater nitrate quantitatively. Results indicate that the nitrate of the Quaternary alluvial pore water (QAP) is significantly higher during the wet season (3.60 to 68.24 mg/L) compared to the dry season (3.53 to 37.20 mg/L). QAP nitrate is significantly higher than that in loess fissure-pore water (LFP), which ranges from 0.66 to 5.47 mg/L during the wet season and 0.82 to 5.01 mg/L during the dry season. The thin and loose vadose zone of QAP makes the aquifer particularly susceptible to anthropogenic influences. Following recharge from LFP, the hydrochemical parameters in QAP increased by 1.22 to 3.12 times (except Na⁺ and pH), the change of average nitrate concentration in QAP (10.11 mg/L) was considerably higher than that in LFP (0.03 mg/L) due to farmland leaching. A significant correlation (R² = 0.70 exists between groundwater nitrate and farmland leaching in river valleys and on slopes where farmland is prevalent. Fertilizer accumulation in river valleys enhances downward leaching, thereby further exacerbating groundwater nitrate. These findings highlight that river valleys with extensive farmland in the Loess Plateau should be prioritized for preventing and controlling groundwater nitrate pollution from agricultural activities.

与农业活动有关的高地下水硝酸盐是一个全球性的环境问题。然而，地下水硝酸盐空间变异性与农业活动量化之间的联系还有待阐明。本文试图解释铜川市黄土区地下水硝酸盐的空间变异，运用水文地球化学和统计学方法识别影响因素，定量分析农田淋溶与地下水硝酸盐的关系。结果表明，第四纪冲积孔隙水（QAP）的硝酸盐含量在丰水期（3.60 ~ 68.24 mg/L）显著高于枯水期（3.53 ~ 37.20 mg/L）。QAP硝态氮含量显著高于黄土裂隙孔隙水（LFP），丰水期为0.66 ~ 5.47 mg/L，枯水期为0.82 ~ 5.01 mg/L。QAP薄而松散的渗透带使含水层特别容易受到人为影响。农田淋滤导致QAP中硝酸盐平均浓度（10.11 mg/L）的变化明显高于LFP (0.03 mg/L)，而补灌后QAP中除Na+和pH外的水化学参数增加了1.22 ~ 3.12倍。在河谷和农田多的坡地，地下水硝酸盐与农田淋滤呈显著相关（R2 = 0.70）。化肥在河谷的积累加速了向下淋滤，从而进一步加剧了地下水硝酸盐的恶化。这些研究结果表明，黄土高原具有广阔农田的河谷应优先防治农业活动对地下水硝酸盐的污染。

The selective catalytic hydrogenation of CO₂ to CO via the RWGS reaction is an effective avenue for resource utilization of CO₂. In this study, we prepared serial La₂O₃-doped Ru catalysts (i.e., RuLa/SBA-15) using a facile sequential impregnation method, and applied it for the selective hydrogenation conversion of CO₂ into CO. The La₂O₃ doping remarkably promotes the dispersion of Ru nanoparticles and induces the formation of electron-deficient Ru species (Ruⁿ⁺). In-situ DRIFTS study reveals that the hydrogenation of CO₂ over Ru catalysts with and without La₂O₃ doping proceeds through different pathways. Both CO and CH₄ are formed on non-doped Ru/SBA-15 with formate as the key intermediate, but only CO is generated on RuLa/SBA-15 via carbonate as the intermediate because of the weakened CO adsorption on Ruⁿ⁺. Thus, RuLa/SBA-15 exhibits outstanding CO selectivity for the hydrogenation of CO₂ without significant decline of activity. It achieves a CO₂ conversion of 51 % at 600 °C and nearly 100 % of CO selectivity across the examined reaction temperature of 300–600 °C, surpassing the performances of the non-doped counterpart (CO₂ conversion of 58 % at 600 °C and CO selectivity ranging from 2 %-63 %). This study provides a facile and cost-effective strategy to tune the structure of Ru catalysts for the hydrogenation conversion of CO₂ to obtain value-added products.

通过RWGS反应选择性催化CO2加氢制CO是CO2资源化利用的有效途径。在本研究中，我们采用简单的顺序浸渍法制备了一系列La2O3掺杂的Ru催化剂（即RuLa/SBA-15），并将其应用于CO2选择性加氢转化为CO。La2O3掺杂显著促进了Ru纳米颗粒的分散，诱导了缺电子Ru物质（Run+）的形成。原位DRIFTS研究表明，掺杂和未掺杂La2O3的Ru催化剂上CO2的加氢通过不同的途径进行。在未掺杂的Ru/SBA-15上，以甲酸盐为关键中间体生成CO和CH4，但由于Run+对CO的吸附减弱，以碳酸盐为中间体在rua /SBA-15上只生成CO。因此，RuLa/SBA-15对CO2的加氢表现出出色的CO选择性，而活性没有明显下降。在600°C下，它的CO2转化率为51%，在300-600°C的反应温度下，CO选择性接近100%，超过了未掺杂的对应物的性能（600°C下CO2转化率为58%，CO选择性范围为2% - 63%）。该研究为调整Ru催化剂的结构以实现CO2加氢转化以获得高附加值产品提供了一种简单而经济的策略。

Metformin, a widely prescribed antidiabetic drug, is frequently detected in aquatic environments due to its limited removal during wastewater treatment. Yet its environmental behaviour and ecological effect on microbial communities at the biogeochemically active sediment–water interface remains poorly understood. We examined metformin degradation and its effect on prokaryotic communities under diverse controlled oxygenation conditions in laboratory microcosms mimicking the sediment–water interface. In autoclaved microcosms, metformin showed slow dissipation without significant formation of transformation products, irrespective of oxygenation conditions. In contrast, biotic microcosms showed metformin biodegradation within 13 days following a lag phase of up to 28 days. Degradation was faster under anoxic conditions. Guanylurea was the sole transformation product detected, suggesting enzymatic hydrolysis and potential use of dimethylamine and guanylurea as carbon and nitrogen sources for microbial growth. Prokaryotic community composition was significantly affected by oxygenation conditions and repeated metformin contamination. Metformin exposure and changes in oxygenation regime had predominantly additive effects. Nevertheless, non-additive effects on procaryotic community composition emerged over time, particularly after repeated metformin exposure. Twenty-one bacterial taxonomic biomarkers of metformin exposure were tentatively identified, including methylotrophic taxa potentially associated with the utilisation of metformin and its metabolites. Microbial activity was essential for metformin dissipation at the sediment–water interface, and oxygenation regime modulated the effect of metformin and its transformation on prokaryotic communities. Our study shows the importance of oxygenation conditions and microbial community responses in assessing the behaviour and associated risks of pharmaceuticals in dynamic aquatic environments such as the sediment–water interface.

二甲双胍是一种广泛使用的降糖药，由于其在废水处理过程中的去除有限，在水生环境中经常被检测到。然而，它的环境行为和对生物地球化学活跃的沉积物-水界面微生物群落的生态影响仍然知之甚少。我们在模拟沉积物-水界面的实验室微观环境中研究了二甲双胍在不同控制氧化条件下的降解及其对原核生物群落的影响。在高压灭菌的微观环境中，二甲双胍表现出缓慢的耗散，而没有显著的转化产物的形成，无论氧合条件如何。相比之下，生物微生物在长达28天的滞后期后13天内显示二甲双胍的生物降解。在缺氧条件下降解速度更快。唯一检测到的转化产物是冠脲醛，这表明二甲胺和冠脲醛有可能被酶解并作为微生物生长的碳源和氮源。氧化条件和二甲双胍反复污染对原核生物群落组成有显著影响。二甲双胍暴露和氧合状态的改变主要是加性效应。然而，对原核生物群落组成的非加性影响随着时间的推移而出现，特别是在反复暴露二甲双胍后。初步鉴定了21个二甲双胍暴露的细菌分类生物标志物，包括可能与二甲双胍及其代谢物利用相关的甲基营养分类群。微生物活性对二甲双胍在沉积物-水界面的耗散至关重要，氧化机制调节二甲双胍及其在原核生物群落中的转化作用。我们的研究显示了氧化条件和微生物群落反应在评估药物在动态水生环境（如沉积物-水界面）中的行为和相关风险中的重要性。

Rotenone is one of the most widely used botanical insecticides. During spraying and residue formation, it can create aerosols that enter the human body through the respiratory tract, posing significant environmental exposure risks. However, the toxicological mechanisms targeting specific organs after inhalation remain unclear, and research on multi-organ toxicity is currently lacking. This study employed in vivo experimental methods to establish an animal model simulating low-dose inhalation exposure scenarios. Mice were exposed to 0.5 h of daily inhalation of rotenone for 28 d at concentrations of 0.36, 3.6, and 5 mg/m³. Histopathological analysis revealed that rotenone exposure exerted toxic effects in the mice lung, brain, and ovarian tissues. The pro-inflammatory factors, tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), and interleukin-2 (IL-2) were significantly elevated in both the brain and lung. The most significant increase in TNF-α levels was observed in brain tissue from the rotenone-treated group (214.52–381.31%). In addition, rotenone exposure reduced alpha diversity of lung microbiota and significantly (***, p ≤ 0.001) increased secretion of endocrine hormones (estradiol, progesterone, and testosterone). This study provides systematic evidence for rotenone-induced multi-organ toxicity following inhalation exposure, offering a new perspective for assessing the health risks of airborne pesticide residues.

鱼藤酮是应用最广泛的植物性杀虫剂之一。在喷洒和残留形成过程中，它会产生通过呼吸道进入人体的气溶胶，造成重大的环境暴露风险。然而，吸入后针对特定器官的毒理学机制尚不清楚，目前缺乏对多器官毒性的研究。本研究采用体内实验方法，建立模拟低剂量吸入暴露情景的动物模型。小鼠每天吸入鱼藤酮0.5小时，浓度分别为0.36、3.6和5 mg/m3，持续28天。组织病理学分析显示，鱼藤酮暴露对小鼠肺、脑和卵巢组织产生毒性作用。脑、肺组织中促炎因子、肿瘤坏死因子（TNF-α）、白细胞介素-1β (IL-1β)、白细胞介素-2 （IL-2）水平均显著升高。鱼藤酮治疗组脑组织中TNF-α水平升高最为显著（214.52 ~ 381.31%）。此外，鱼tenone暴露降低了肺微生物群的α多样性，并显著（***,p≤0.001）增加了内分泌激素（雌二醇、黄体酮和睾酮）的分泌。本研究为鱼藤酮吸入后引起的多器官毒性提供了系统证据，为评估空气中农药残留的健康风险提供了新的视角。
