Assessing the balance between ecosystem service supply and demand (ESSD) relationship and identifying its driving factors is essential for addressing ecosystem degradation. While previous local-scale studies have highlighted climate change and human activities as critical influences, their roles at a global scale remain poorly understood. Here, we analyze the global dynamics of supply–demand relationships for four key ecosystem services—food production, carbon sequestration, soil conservation, and water yield—over the period 2000–2020. We find that ESSD relationships generally exhibit spatially high supply-low demand and quantitatively surplus characteristics. Climate change and human activity influence ESSD relationships in dual-directional pathways. Specifically, they positively affect food production and soil conservation in 80.69 % and 72.50 % of global regions respectively; while negatively influencing carbon sequestration and water yield in 76.74 % and 62.44 % of global regions respectively. Human activity primarily shapes the ESSD relationships for food production and carbon sequestration, with mean contribution rates of 66.54 % and 60.80 % respectively; whereas climate change exerts greater control over soil conservation and water yield, with mean contribution rates of 54.62 % and 55.41 % respectively. Our findings clarify the direction (positive or negative), mode (individual or combined), contribution rates, and geographic distribution of these impacts. This research closes a critical gap in understanding global ESSD relationships and provides essential insights to inform sustainable ecosystem management from local to global scales.

评估生态系统服务供需平衡关系并确定其驱动因素是解决生态系统退化问题的关键。虽然以前的局地尺度研究强调了气候变化和人类活动的关键影响，但它们在全球尺度上的作用仍然知之甚少。本文分析了2000-2020年期间四种关键生态系统服务（粮食生产、碳固存、土壤保持和水产量）的全球供需关系动态。研究发现，ESSD关系普遍表现出空间上的高供给-低需求和数量上的过剩特征。气候变化和人类活动对ESSD关系的影响是双向的。其中，对全球80.69%和72.50%的地区的粮食生产和土壤保持具有积极影响；而对全球76.74%和62.44%的区域固碳和产水分别产生负面影响。人类活动主要影响粮食生产和碳固存的ESSD关系，平均贡献率分别为66.54%和60.80%；而气候变化对土壤保持和水分产量的影响更大，平均贡献率分别为54.62%和55.41%。我们的发现阐明了这些影响的方向（积极或消极）、模式（单独或联合）、贡献率和地理分布。这项研究填补了理解全球生态系统可持续发展关系的关键空白，并为从地方到全球范围的可持续生态系统管理提供了重要见解。

Antibiotics are increasingly prevalent in global environments, driving antimicrobial resistance and disrupting microbial cycling. These impacts pose threats to human, animal, and environmental health. Therefore, addressing this emergent issue necessitates a One Health framework that integrates these interconnected dimensions. Here we systematically review 137 antibiotics across diverse global environmental compartments. We find that sulfonamides, macrolides, quinolones, and tetracyclines are globally ubiquitous, particularly prevalent in Asia and Africa, whereas β-lactams dominates in Europe. Hierarchical clustering revealed ten priority antibiotics in liquid phases and eight in solid phases requiring urgent attention. Regional analysis indicated the highest antibiotic concentrations within wastewater treatment plant liquids in the Americas and surface waters in Africa, with generally lower levels detected in Asia and Europe. Utilizing a One Health assessment framework, we integrated Predicted No-Effect Concentrations for antibiotic resistance selection (PNEC_RS) relevant to human and animal health with Minimum Inhibitory Concentrations (MICs) affecting microbial nitrogen cycling processes. Risk assessment highlighted wastewater treatment plant liquids (20 % average exceedance) and animal manure (44 % average exceedance) as the most critical compartments. Africa exhibited the highest overall risk, averaging a 53 % exceedance rate. Notably, ciprofloxacin and ofloxacin in liquid phases, as well as enrofloxacin and norfloxacin in solid phases, emerged as antibiotics posing significant One Health risks. This study advances our understanding of antibiotic distribution globally, offering a foundation for targeted interventions to mitigate antibiotic-related risks across human, animal, and environmental health sectors.

抗生素在全球环境中日益普遍，推动了抗菌素耐药性并破坏了微生物循环。这些影响对人类、动物和环境健康构成威胁。因此，解决这一紧急问题需要一个统一健康框架，该框架集成了这些相互关联的方面。在这里，我们系统地回顾了137种抗生素在不同的全球环境隔间。我们发现磺胺类药物、大环内酯类药物、喹诺酮类药物和四环素类药物在全球普遍存在，尤其是在亚洲和非洲，而β-内酰胺类药物在欧洲占主导地位。分层聚类揭示了10种优先的液相抗生素和8种迫切需要关注的固相抗生素。区域分析表明，美洲和非洲地表水的废水处理厂液体中抗生素浓度最高，亚洲和欧洲检测到的水平普遍较低。利用One Health评估框架，我们整合了与人类和动物健康相关的抗生素耐药性选择的预测无效应浓度（PNECRS）和影响微生物氮循环过程的最低抑制浓度（mic）。风险评估强调废水处理厂液体（平均超标20%）和动物粪便（平均超标44%）是最关键的隔间。非洲的总体风险最高，平均超过53%。值得注意的是，液相的环丙沙星和氧氟沙星，以及固相的恩诺沙星和诺氟沙星，成为对健康构成重大威胁的抗生素。这项研究促进了我们对抗生素全球分布的理解，为有针对性的干预措施提供了基础，以减轻人类、动物和环境卫生部门的抗生素相关风险。

Under national carbon neutrality targets, energy-producing regions hold significant responsibilities for reducing emissions. Given the diverse economic, industrial, and resource profiles of these regions, tailored strategies are essential for designing regional emission pathways. Currently, a systematic analysis that simultaneously integrates broader national climate objectives and regional heterogeneity is lacking, hindering the formulation of localized roadmaps. To address this gap, we propose an integrated analytical framework combing top-down and bottom-up approaches. It considers macro-level constraints (socio-economic development) and micro-level feasibility (renewable energy potential and forest carbon sinks), incorporating diverse regional characteristics such as resource endowment, energy consumption patterns, and industrial structures. We apply this approach to an energy-producing region in central China. Our analysis highlights the need for a clean energy transition that maintains energy security and meets growing electricity demands. By 2060, wind and solar power are projected to account for 87 % of electricity generation, representing a substantial shift from the current fossil-fuel-dependent structure. Significant reductions in greenhouse gas emissions can be achieved by optimizing the energy structure, enforcing production controls, and deploying advanced technologies across industry, transportation, and buildings. Additionally, enhancing carbon removal strategies will further support emission reduction targets. This framework demonstrates the feasibility of achieving climate objectives in fossil-fuel-dependent regions, providing strategic guidance for integrating regional traits into national decarbonization plans.

根据国家碳中和目标，能源生产地区在减排方面负有重大责任。鉴于这些地区不同的经济、工业和资源状况，量身定制的战略对于设计区域排放路径至关重要。目前，缺乏同时整合更广泛的国家气候目标和区域异质性的系统分析，阻碍了本地化路线图的制定。为了解决这一差距，我们提出了一个结合自顶向下和自底向上方法的综合分析框架。它考虑宏观层面的制约因素（社会经济发展）和微观层面的可行性（可再生能源潜力和森林碳汇），并结合不同的区域特征，如资源禀赋、能源消费模式和产业结构。我们将这种方法应用于中国中部的一个能源产区。我们的分析强调了清洁能源转型的必要性，以维护能源安全并满足日益增长的电力需求。到2060年，风能和太阳能预计将占到总发电量的87%，这意味着目前依赖化石燃料的结构将发生重大转变。通过优化能源结构、加强生产控制以及在工业、交通和建筑领域部署先进技术，可以显著减少温室气体排放。此外，加强碳清除战略将进一步支持减排目标。该框架展示了在依赖化石燃料的地区实现气候目标的可行性，为将区域特征纳入国家脱碳计划提供了战略指导。

Chromophoric dissolved organic matter (CDOM), characterized by unique optical properties, is an essential indicator for understanding aquatic organic matter dynamics within global carbon cycles. Soil erosion, a major source of CDOM received by lakes, transports terrestrial organic matter to water bodies, altering sources, bioavailability and molecular complexity of CDOM significantly. Yet, the spatial patterns of CDOM in lakes from different soil erosion regions are still unknown. Here, we developed a robust machine learning framework (RMSE_calibration = 0.87 m^-1) to estimate CDOM concentrations in lakes by integrating over 1300 in situ water samples with Landsat 8 OLI surface reflectance data. We then applied this model to map the spatial distribution of CDOM across lakes larger than 0.1 km² in 2020. Our analysis revealed distinct spatial patterns, with mean CDOM absorption coefficients at 355 nm of 3.73 m^-1 in freeze-thaw erosion regions, 6.31 m^-1 in wind erosion regions, and 3.72 m^-1 in hydraulic erosion regions, reflecting significant variations driven by erosion intensity. Two axes of PCA analysis explained over 48 % variations of CDOM for different soil erosion types. Chemical characterization indicated that polycyclic aromatic predominated in wind and hydraulic erosion regions, whereas freeze-thaw erosion regions exhibited higher proportions of peptides and unsaturated aliphatic compounds. This study highlights the crucial connection between terrestrial soil erosion processes and aquatic DOM composition, providing vital insights for evaluating global carbon cycling and carbon storage within inland ecosystems.

显色性溶解有机物（CDOM）具有独特的光学性质，是了解全球碳循环中水生有机物动态的重要指标。土壤侵蚀是湖泊吸收CDOM的主要来源，它将陆源有机质输送到水体中，显著改变了CDOM的来源、生物有效性和分子复杂性。然而，不同土壤侵蚀区湖泊CDOM的空间格局尚不清楚。在这里，我们开发了一个强大的机器学习框架（rmsecaration = 0.87 m-1），通过整合1300多个原位水样和Landsat 8 OLI表面反射率数据来估计湖泊中的CDOM浓度。然后，我们将该模型应用于2020年面积大于0.1 km2的湖泊的CDOM空间分布图。冻融化侵蚀区、风蚀区和水力侵蚀区在355 nm处的平均CDOM吸收系数分别为3.73 m-1、6.31 m-1和3.72 m-1，反映了侵蚀强度的显著变化。两轴主成分分析解释了不同土壤侵蚀类型下超过48%的CDOM变化。化学表征表明，风蚀区和水蚀区以多环芳香族化合物为主，冻融侵蚀区则以多肽和不饱和脂肪化合物为主。该研究强调了陆地土壤侵蚀过程与水生DOM组成之间的重要联系，为评估内陆生态系统的全球碳循环和碳储存提供了重要见解。

Sustainable detoxification and advanced treatment of toxic organic pollutants (TOPs) in wastewater are essential for water reclamation and ecosystem security. Although biological treatment is a low-carbon and eco-friendly approach for TOPs degradation, its effectiveness is often limited by the high toxicity and recalcitrance of TOPs. Oxidative and reductive reactions can degrade TOPs according to their intrinsic redox potentials. However, conventional biological or chemical oxidation treatment often fails to efficiently or purposefully cleave key functional groups, which leads to unsatisfactory performance of biological reactions or excessive chemical oxidation costs. This perspective proposes redox regulation as a strategy to moderately catalyse the oxidation or reduction of TOPs and thereby generate low toxicity and increased biodegradable intermediates, which will improve subsequent biological treatment. We summarize strong redox regulation techniques, including advanced oxidation and reduction processes, and weak redox regulation through low-energy electrical potential, along with the corresponding mechanisms and applications. Additionally, we explore the integration of redox regulation with biological treatment, either in a sequential mode or in situ. This study emphasizes the need for future research to focus on targeted and durable catalytic detoxification processes and to optimize balancing the carbon footprint, process control, operational efficiency, and economic feasibility. By integrating chemical reactions with microbial metabolism, redox regulation has the potential to transform wastewater treatment from isolated process optimization to a holistic approach. This perspective advocates for innovation of conventional wastewater detoxification technologies to achieve sustainable water purification and ecological risk control.

废水中有毒有机污染物（TOPs）的可持续解毒和深度处理对水回收和生态系统安全至关重要。虽然生物处理是一种低碳、环保的降解TOPs的方法，但其效果往往受到TOPs的高毒性和难降解性的限制。氧化和还原反应可以根据其固有的氧化还原电位来降解TOPs。然而，传统的生物或化学氧化处理往往不能有效或有目的地切割关键官能团，从而导致生物反应性能不理想或化学氧化成本过高。这一观点提出，氧化还原调节是一种适度催化TOPs氧化或还原的策略，从而产生低毒性和增加可生物降解的中间体，这将改善后续的生物处理。本文综述了强氧化还原调控技术，包括高级氧化还原过程和低能量电位弱氧化还原调控技术，以及相应的机制和应用。此外，我们探索了氧化还原调控与生物处理的整合，无论是在顺序模式还是在原位。本研究强调了未来的研究需要关注有针对性和持久的催化解毒过程，并优化平衡碳足迹，过程控制，操作效率和经济可行性。通过将化学反应与微生物代谢相结合，氧化还原调控有可能将废水处理从孤立的过程优化转变为整体方法。这一观点提倡创新传统的废水解毒技术，以实现可持续的水净化和生态风险控制。

Conventional ecological risk assessments prioritize downstream anthropogenic impacts, overlooking risks arising from upstream processes involving highly hazardous substances and indirect emissions. This narrow focus obscures high-risk hotspots and renders traditional methodologies ill-suited for evaluating novel chemical entities. Nanopesticides, designed for targeted delivery of pesticidal active ingredients, are increasingly deployed to enhance efficiency, yet their altered environmental fate and transport dynamics may reshape end-of-life risks while their full lifecycle impacts remain uncharacterized. Here, we address this gap using imidacloprid (IMI) and its nano-encapsulated variant (nano-IMI) as case studies. By applying life cycle assessment and integrating the USEtox ecotoxicity model with the nano-specific SimpleBox4Nano framework, we quantify "cradle-to-gate" environmental impacts and derive substance-specific ecotoxicity metrics, enabling systematic characterization of end-of-life risks associated with these formulations. Production-stage ecological risks of nano-IMI (4.63 × 10³ CTUe) are approximately four times greater than those for conventional IMI (1.18 × 10³ CTUe). However, end-of-life freshwater ecological risks from nano-IMI emissions (0.012–6.93 × 10⁴ CTUe) are 2–5 orders of magnitude lower compared with IMI (1.59 × 10³–6.13 × 10⁶ CTUe), accounting for rainfall variability, toxicity data selection, fate, and environmental transport scenarios. Under equivalent rainfall conditions, nano-IMI exhibited up to three orders of magnitude lower integrated life-cycle freshwater ecological risks, underscoring its potential as an environmentally preferable alternative to conventional IMI. This research introduces a comprehensive and novel methodology for evaluating engineered nanomaterial alternatives across realistic environmental scenarios, providing essential insights into nanopesticide risk assessment throughout their lifecycle.

传统的生态风险评估优先考虑下游的人为影响，忽略了涉及高度有害物质和间接排放的上游过程产生的风险。这种狭隘的焦点模糊了高风险的热点，使得传统的方法不适合评估新的化学实体。纳米农药是为靶向递送农药活性成分而设计的，越来越多地用于提高效率，然而，它们改变的环境命运和运输动态可能会重塑生命末期的风险，而其整个生命周期的影响仍不清楚。在这里，我们使用吡虫啉（IMI）及其纳米封装变体（nano-IMI）作为案例研究来解决这一差距。通过应用生命周期评估，并将USEtox生态毒性模型与纳米特异性SimpleBox4Nano框架相结合，我们量化了“从摇篮到闸门”的环境影响，并得出了特定物质的生态毒性指标，从而能够系统地表征与这些配方相关的生命末期风险。纳米IMI （4.63 × 103 CTUe）的生产阶段生态风险约为常规IMI （1.18 × 103 CTUe）的4倍。然而，考虑到降雨变率、毒性数据选择、命运和环境运输情景，纳米IMI排放（0.012-6.93 × 104 CTUe）的生命末期淡水生态风险比IMI （1.59 × 103-6.13 × 106 CTUe）低2-5个数量级。在相同的降雨条件下，纳米IMI的综合生命周期淡水生态风险降低了3个数量级，强调了其作为传统IMI的环保替代品的潜力。本研究介绍了一种全面而新颖的方法，用于评估工程纳米材料在现实环境中的替代品，为纳米农药在其整个生命周期中的风险评估提供了重要的见解。

Antibiotic release and transfer within environmental systems significantly impact ecological stability and human health, posing considerable safety risks. Consequently, accurate and efficient detection methods for antibiotics, particularly within complex environmental matrices, are essential. A growing body of research is focusing on antibiotic pollution in wastewater and other environmental settings. Nevertheless, pervasive matrix interferences in complex water matrices and the inherent limitations of standalone analytical approaches in sensitivity, detection range, and other performance metrics underscore the demand for more robust and versatile detection platforms. Here we show a comprehensive overview and critical assessment of antibiotic contaminants, examining their sources, environmental distribution, and current detection methods. We focus on emerging antibiotic detection technologies, comparing their performance and highlighting suitable application contexts. Furthermore, we discuss fundamental principles and historical advancements in antibiotic detection and analytical methodologies. Finally, we identify significant challenges for antibiotic detection in complex environments, suggest viable strategies for future improvements, and outline promising research directions. This review not only provides essential guidance for advancing environmental antibiotic monitoring but also sheds light on the development of a strategic framework for robust, integrated platforms enabling multiplexed antibiotic monitoring in challenging environmental water matrices.

Rainfall measurement at high quality and spatiotemporal resolution is essential for urban hydrological modeling and effective stormwater management. However, traditional rainfall measurement methods face limitations regarding spatial coverage, temporal resolution, and data accessibility, particularly in urban settings. Here, we show a novel rainfall estimation framework that leverages surveillance cameras to enhance estimation accuracy and spatiotemporal data coverage. Our hybrid approach consists of two complementary modules: the first employs an image-quality signature technique to detect rain streaks from video frames and selects optimal regions of interest (ROIs). The second module integrates depthwise separable convolution (DSC) layers with gated recurrent units (GRU) in a regression model to accurately estimate rainfall intensity using these ROIs. We evaluate the framework using video data from two locations with distinct rainfall patterns and environmental conditions. The DSC–GRU model achieves high predictive performance, with coefficient of determination (R²) values ranging from 0.89 to 0.93 when validated against rain gauge measurements. Remarkably, the model maintains strong performance during daytime and nighttime conditions, outperforming existing video-based rainfall estimation methods and demonstrating robust adaptability across variable environmental scenarios. The model's lightweight architecture facilitates efficient training and deployment, enabling practical real-time urban rainfall monitoring. This work represents a substantial advancement in rainfall estimation technology, significantly reducing estimation errors and expanding measurement coverage, and provides a practical, low-cost solution for urban hydrological monitoring.

高质量和高时空分辨率的降雨测量对于城市水文建模和有效的雨水管理至关重要。然而，传统的降雨测量方法在空间覆盖、时间分辨率和数据可及性方面存在局限性，特别是在城市环境中。在这里，我们展示了一种新的降雨估计框架，该框架利用监控摄像机来提高估计精度和时空数据覆盖率。我们的混合方法由两个互补的模块组成：第一个模块采用图像质量签名技术从视频帧中检测雨纹并选择最佳感兴趣区域（roi）。第二个模块将深度可分离卷积（DSC）层与门控循环单元（GRU）集成在回归模型中，以使用这些roi准确估计降雨强度。我们使用来自两个具有不同降雨模式和环境条件的地点的视频数据来评估该框架。DSC-GRU模型具有很高的预测性能，与雨量计测量值进行验证时，决定系数（R2）值在0.89至0.93之间。值得注意的是，该模型在白天和夜间条件下都保持了较强的性能，优于现有的基于视频的降雨估计方法，并展示了对各种环境情景的强大适应性。该模型的轻量级架构有助于有效的培训和部署，实现实际的实时城市降雨监测。这项工作代表了降雨估算技术的实质性进步，显著降低了估算误差，扩大了测量范围，为城市水文监测提供了一种实用、低成本的解决方案。

N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and its oxidation derivative, 6PPD-quinone (6PPDQ), have been extensively detected in environmental and biological samples, raising significant concerns regarding their chronic aquatic toxicity at environmentally relevant concentrations. However, the underlying mechanisms driving this chronic toxicity remain largely unexplored. Here we show that zebrafish exposed to 6PPD and 6PPDQ exhibit distinct toxicokinetic profiles, with 6PPD preferentially accumulating in the liver and 6PPDQ predominantly targeting the brain. Exposure to both compounds impaired zebrafish growth, induced hepatic damage, and disrupted locomotor behavior. Transcriptomic analysis of liver tissue revealed disturbances in lipid and carbohydrate metabolic pathways in both treatment groups, with distinct differences in gene expression patterns and biochemical responses between 6PPD and 6PPDQ. Specifically, both compounds downregulated peroxisome proliferator-activated receptor gamma (PPARγ) and elevated the expression of pro-inflammatory cytokines (TNF-α and IL-6). Molecular dynamics simulations and surface plasmon resonance experiments further demonstrated that hepatotoxicity was associated with direct binding of these compounds to PPARγ, a critical regulator of lipid metabolism and inflammation. Our findings highlight the hepatotoxic risks of 6PPD and 6PPDQ to aquatic life. Importantly, 6PPDQ exhibited greater toxicity compared to 6PPD, emphasizing an urgent need for targeted environmental controls and regulatory actions to mitigate ecological harm and potential public health consequences.

N-（1,3-二甲基丁基）-N ' -苯基-对苯二胺（6PPD）及其氧化衍生物6PPD-醌（6PPDQ）已在环境和生物样品中广泛检测到，引起了对其在环境相关浓度下的慢性水生毒性的重大关注。然而，驱动这种慢性毒性的潜在机制在很大程度上仍未被探索。本研究表明，暴露于6PPD和6PPDQ的斑马鱼表现出不同的毒性动力学特征，6PPD优先在肝脏积累，而6PPDQ主要针对大脑。暴露于这两种化合物会损害斑马鱼的生长，引起肝损伤，并扰乱运动行为。肝脏组织转录组学分析显示，两个治疗组的脂质和碳水化合物代谢途径均出现紊乱，6PPD和6PPDQ在基因表达模式和生化反应方面存在明显差异。具体来说，这两种化合物都下调过氧化物酶体增殖物激活受体γ (PPARγ)并升高促炎细胞因子（TNF-α和IL-6）的表达。分子动力学模拟和表面等离子体共振实验进一步证明，肝毒性与这些化合物与PPARγ的直接结合有关，PPARγ是脂质代谢和炎症的关键调节因子。我们的研究结果强调了6PPD和6PPDQ对水生生物的肝毒性风险。重要的是，与6PPD相比，6PPDQ表现出更大的毒性，强调迫切需要有针对性的环境控制和监管行动，以减轻生态危害和潜在的公共卫生后果。

Efficient management of temporal latency and spatial heterogeneity remains a critical challenge in sensor-based pH regulation for smart water management, primarily due to inherent response delays and mass transfer constraints. In oxidation systems with dynamic pH environments, delayed responses can lead to issues such as cyanide release, unwanted side reactions, or pipe damage. To address these challenges, we propose a “pause-then-adjust” control strategy, exploiting the pH-responsive generation of hydroxyl radicals (^•OH) in a modified Fenton reaction system. This system utilizes hydroxylamine as an electron donor and ethylenediaminetetraacetic acid (EDTA) as a stabilizer for iron ions. Within the pH range of 7.0–10.0, the coexistence of [Fe²⁺-EDTA]²⁻ and [Fe³⁺-OH-EDTA]²⁻ complexes facilitates efficient electron transfer, resulting in the selective and sustained production of ^•OH radicals. The inherent pH-responsiveness of this strategy enables rapid and spatially coherent adjustments, offering a robust supplementary method for addressing complex and evolving requirements in advanced water treatment systems.

有效管理时间延迟和空间异质性仍然是基于传感器的智能水管理pH调节的关键挑战，主要是由于固有的响应延迟和传质限制。在具有动态pH环境的氧化系统中，延迟反应可能导致氰化物释放、不良副反应或管道损坏等问题。为了解决这些挑战，我们提出了一种“暂停然后调整”的控制策略，利用改进的芬顿反应体系中羟基自由基（•OH）的ph响应生成。该系统利用羟胺作为电子供体，乙二胺四乙酸（EDTA）作为铁离子的稳定剂。在7.0 ~ 10.0的pH范围内，[Fe2+-EDTA]2−和[Fe3+-OH-EDTA]2−配合物的共存有利于有效的电子转移，从而选择性地持续产生•OH自由基。该策略固有的ph响应性使快速和空间一致的调整成为可能，为解决高级水处理系统中复杂和不断变化的要求提供了一种强大的补充方法。
