Membrane technology is pivotal in water reuse for limiting disinfection byproduct (DBP) formation in surface water and wastewater, enabling safe potable and non-potable applications. Wastewater effluents, rich in dissolved organic matter (DOM), act as major DBP precursors, posing challenges for water reclamation. Pretreatment-enhanced or hybrid membrane systems have emerged as essential strategies to control DBP formation and ensure water quality. This mini review critically examines recent advances in microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverses osmosis (RO) membranes for controlling DBP formation. While NF and RO can achieve up to 90–99 % removal of dissolved organic matter (DOM) and effectively reduce DBP formation potential (DBPFP) by over 80 %, MF and UF alone are limited in NOM/DBPFP removal and typically require integration with coagulation or other pretreatment processes for significant DBP control. However, low-molecular-weight neutral DBPs like NDMA remain challenging, with rejection rates frequently below 40 %. Hybrid systems, including ozonation-NF and photocatalytic membrane processes, show enhanced DBP removal efficiencies of up to 95 %, while offering benefits in fouling control and operational stability. Despite these advances, challenges persist in scalability, cost, and the environmental sustainability of emerging membrane materials. Future research should prioritize the integration of advanced nanomaterials, machine learning-driven membrane design, and life cycle assessments to enable safe and economically viable DBP management in water treatment and reuse.

膜技术在水回用中至关重要，可以限制地表水和废水中消毒副产物（DBP）的形成，从而实现安全的饮用水和非饮用水应用。富含溶解有机物（DOM）的废水是DBP的主要前体，对水的回收提出了挑战。预处理强化或混合膜系统已成为控制DBP形成和确保水质的基本策略。本文综述了微滤（MF）、超滤（UF）、纳滤（NF）和反渗透（RO）膜在控制DBP形成方面的最新进展。虽然NF和RO可以实现高达90 - 99%的溶解有机物（DOM）去除，并有效降低DBPFP （DBPFP）超过80%，但MF和UF单独去除NOM/DBPFP的能力有限，通常需要与混凝或其他预处理工艺相结合才能有效控制DBP。然而，像NDMA这样的低分子量中性dbp仍然具有挑战性，其排斥率通常低于40%。混合系统，包括臭氧氧化-纳滤和光催化膜处理，显示DBP去除效率高达95%，同时在污染控制和运行稳定性方面具有优势。尽管取得了这些进步，但新兴膜材料在可扩展性、成本和环境可持续性方面仍然存在挑战。未来的研究应优先考虑先进纳米材料、机器学习驱动的膜设计和生命周期评估的整合，以实现水处理和再利用中安全、经济可行的DBP管理。

Per and polyfluoroalkyl substances are durable synthetic organofluorines, and their toxicity has led to a worldwide environmental and public health dilemma. While their ubiquitous presence in air, water, food, and human serum is well documented, there are significant inequalities in how these substances are monitored, regulated, and managed, especially in developing areas where systems are inadequate or nonexistent. Current review underlines how technical deficiencies, poor governance, and socioeconomic barriers escalate PFAS risks throughout the Global South. This review covers remediation technologies such as adsorption, membrane separation, advanced oxidation, plasma treatment, and biochar based solutions, highlighting their potential and their challenges. Bridging data and treatment gaps will necessitate region-specific fate-and-transport models, open-access monitoring, and AI/ML driven predictive tools for flexible solutions. International binding agreements, technology transfer, and polluter pays strategies are essential. The management of PFAS necessitates a global approach that incorporates interdisciplinary methods and emphasizes justice-oriented solutions.

Per和多氟烷基物质是耐用的合成有机氟，它们的毒性已导致世界范围内的环境和公共卫生困境。虽然它们在空气、水、食物和人类血清中无处不在，但在如何监测、管制和管理这些物质方面存在重大不平等，特别是在系统不充分或不存在系统的发展中地区。目前的审查强调了技术缺陷、治理不善和社会经济障碍如何使整个南半球的PFAS风险升级。本文综述了吸附、膜分离、深度氧化、等离子体处理和生物炭等修复技术，重点介绍了它们的潜力和面临的挑战。弥合数据和治疗差距将需要针对特定区域的命运和运输模型、开放获取监测以及人工智能/机器学习驱动的预测工具，以实现灵活的解决方案。国际约束性协议、技术转让和污染者付费战略至关重要。PFAS的管理需要一种综合跨学科方法的全球方法，并强调以正义为导向的解决方案。

Hospital wastewater in upper middle-income countries (UMICs) is a major source of antibiotic residues, resistant bacteria, and resistance genes due to limited treatment and surveillance. This review synthesizes evidence to assess the scale of the problem, highlight knowledge gaps, and guide strategies to curb antimicrobial resistance spread. Conducted under PRISMA guidelines, the review analyzed studies from 2015 to 2025 on antibiotic residues, resistant bacteria, and resistance genes in hospital wastewater from UMICs, with emphasis on treatment technologies and public health risks. Fifty-seven studies showed that hospital wastewater in UMICs contains high levels of antibiotic residues, resistant bacteria, and resistance genes, even after conventional treatment. Multidrug-resistant pathogens such as E. coli, K. pneumoniae, P. aeruginosa, and A. baumannii were frequently reported, with resistance to last resort antibiotics including carbapenems and colistin. Findings underscore limitations of conventional treatment, risks of horizontal gene transfer, and urgent need for advanced technologies and stronger public protection measures.

中高收入国家（UMICs）的医院废水是抗生素残留、耐药细菌和耐药基因的主要来源，原因是治疗和监测有限。本综述综合了证据，以评估问题的规模，突出知识差距，并指导遏制抗微生物药物耐药性传播的战略。根据PRISMA的指导方针，该审查分析了2015年至2025年关于UMICs医院废水中抗生素残留、耐药细菌和耐药基因的研究，重点是处理技术和公共卫生风险。57项研究表明，即使经过常规处理，UMICs的医院废水也含有高水平的抗生素残留、耐药细菌和耐药基因。经常报道多重耐药病原体，如大肠杆菌、肺炎克雷伯菌、铜绿假单胞菌和鲍曼假单胞菌，并对包括碳青霉烯类和粘菌素在内的最后手段抗生素具有耐药性。研究结果强调了常规治疗的局限性、水平基因转移的风险以及迫切需要先进的技术和更强有力的公共保护措施。

Disinfection/oxidation byproducts (DBPs) are formed during water treatment. Nitrogenous DBPs (N-DBPs) are generally more toxic than the DBPs without nitrogen. Recently, DBPs of more than two carbons (“higher-carbon DBPs”) have been reported, but the status of higher-carbon N-DBP research has not been reviewed. This review assembled 355 individual compounds/structures of emerging higher-carbon N-DBPs and summarized the occurrence, precursors, and oxidation treatment for the 12 major classes (196 compounds/structures), including halogenated aromatic/cyclic compounds (nitrophenols, anilines, benzoquinone imines, pyridines, pyrroles, imidazoles, indoles, and nucleobases), as well as aliphatic/aromatic/cyclic compounds featuring nitrile, amide, and imide functional groups. Almost half of the major higher-carbon N-DBPs were confirmed by standards, but mass spectrometry-based identification is also common. Chlorination was the most studied disinfection method for higher-carbon N-DBPs, followed by chloramination and pre-ozonation, while chlorine dioxide and UV were not commonly considered. The levels of higher-carbon N-DBPs in real water samples ranged from <0.1 to ∼100 ng/L based on the limited studies, but their global occurrence remains unknown. Preliminary toxicity assessment showed that higher-carbon N-DBPs were more toxic than their non-nitrogenous analogues and the regulated DBPs. Potential synergy between the research of DBPs and contaminants of emerging concern (CECs) was discussed, as CECs can serve as a significant but previously overlooked source of precursors for both higher-carbon N-DBPs and the high-priority small-molecule DBPs. Strengthening the synergy between the research on DBPs and advanced oxidation processes (AOPs), especially regarding nitrogen-incorporation during AOP, will contribute to our understanding on the formation of higher-carbon N-DBPs.

消毒/氧化副产物（DBPs）在水处理过程中形成。含氮DBPs （N-DBPs）通常比不含氮DBPs毒性更大。近年来，已有两碳以上dbp（“高碳dbp”）的报道，但高碳N-DBP的研究现状尚未得到综述。本文综述了新兴的高碳N-DBPs的355个单独的化合物/结构，并总结了12大类（196个化合物/结构）的存在、前体和氧化处理，包括卤代芳香/环化合物（硝基酚、苯胺、苯醌亚胺、吡啶、吡咯、咪唑、吲哚和核碱基），以及含有腈、酰胺和亚胺官能团的脂肪族/芳香/环化合物。几乎一半的主要高碳n - dbp被标准确认，但基于质谱的鉴定也很常见。对高碳N-DBPs的消毒方法研究最多的是氯化法，其次是氯胺化法和预臭氧化法，而二氧化氯和紫外线消毒方法较少。根据有限的研究，实际水样中高碳N-DBPs的水平在0.1至100纳克/升之间，但其全球分布情况尚不清楚。初步毒性评估表明，高碳N-DBPs比它们的非氮类似物和受调控的DBPs毒性更大。讨论了DBPs和新兴关注污染物（CECs）研究之间的潜在协同作用，因为CECs可以作为高碳N-DBPs和高优先级小分子DBPs的重要前体来源，但以前被忽视。加强DBPs与高级氧化过程（AOPs）研究之间的协同作用，特别是在AOP过程中氮的掺入，将有助于我们对高碳N-DBPs形成的理解。

Brominated and iodinated disinfection by-products: Recent advances in formation, characterization, and toxicity 溴化和碘化消毒副产物：形成、表征和毒性的最新进展

IF 6.6 Q1 ENVIRONMENTAL SCIENCES

Current Opinion in Environmental Science and Health

The formation of brominated and iodinated disinfection by-products is of concern due to impaired water quality, taste- and odor-issues, and health concerns. Progress in the identification of precursors among the complex organic matter reveals that low-molecular-weight by-products are the main toxicity drivers. These by-products could, however, originate from the degradation of high-molecular-weight organic matter, especially in the presence of iodide during chlorination or chloramination and algal bloom events. Alternative oxidants such as peracids or periodate reach different levels of assessment, considering the formation of by-products, demonstrating breakthroughs in this field but also remaining gaps to be filled.

由于水质受损、味道和气味问题以及健康问题，溴化和碘化消毒副产物的形成令人担忧。复杂有机物中前体的鉴定进展表明，低分子量的副产物是主要的毒性驱动因素。然而，这些副产物可能源于高分子量有机物的降解，特别是在氯化或氯胺化和藻华事件期间存在碘化物的情况下。考虑到副产品的形成，过酸盐或高碘酸盐等替代氧化剂达到了不同的评估水平，这表明该领域取得了突破，但也存在有待填补的空白。

Plastic pollution is now a major microbiological and biogeochemical challenge. This review critically evaluates the plastisphere, the microbial biofilm colonizing plastic debris, and establishes its role as an engine of environmental change. We posit the central hypothesis that the plastisphere functions as a mobile hotspot of microbial activity that disrupts natural biogeochemical cycles and introduces novel pollutant dynamics. To evaluate this, we investigate three key questions: (1) how does the metabolic core of the plastisphere reconcile high in vitro enzymatic potential with limited in situ degradation efficacy? (2) what is the dual role of the plastisphere in pollutant fate, acting as both a transport vector and a bioreactor? (3) how are these functions intensified by global change drivers? Our synthesis concludes that the plastisphere collective metabolism short-circuits natural elemental cycles and introduces novel pollutant vectors. Addressing this multidimensional threat requires interdisciplinary research to inform both mitigation policies and the transition to a circular plastic economy.

塑料污染现在是一个主要的微生物和生物地球化学挑战。这篇综述批判性地评估了塑料球，微生物生物膜定植塑料碎片，并确立了其作为环境变化引擎的作用。我们假设塑性球作为微生物活动的移动热点，破坏自然生物地球化学循环并引入新的污染物动力学。为了评估这一点，我们研究了三个关键问题：(1)塑性球的代谢核心如何协调高体外酶促电位和有限的原位降解效率？(2)塑料球在污染物命运中的双重作用是什么，既是运输载体又是生物反应器？(3)全球变化驱动因素如何强化这些功能？我们的综合结论是，塑性球的集体代谢缩短了自然元素循环，并引入了新的污染物载体。解决这一多维威胁需要进行跨学科研究，为缓解政策和向循环塑料经济过渡提供信息。

Urban runoff, shaped by human activities and land use, is a key source of microplastics (MPs), contributing to the contamination of rivers, groundwater, and coastal systems. Understanding MP sources, variability, and behaviour in urban runoff remains challenging due to their diverse origins and dynamic transport processes. Flood events accelerate the mobilisation of MPs, redistributing particles across catchments and ecosystems. Processes like fragmentation, ageing, and retention alter MPs’ size, shape, and surface properties, influencing their transport, accumulation, and interactions in different environments. This opinion article examines the potential of MP profiling to evaluate the extent and pathways of surface-groundwater interactions in urbanizing landscapes, with a focus on flood impacts. The study further highlights the coexistence of MPs with other pollutants and their potential infiltration into groundwater. Through analysis of microplastic contaminant loads, composition, and transport during and after flood events, this opinion demonstrates their dual function as markers of flood occurrences and tools for evaluating hydrological connectivity altered by urban development. The findings highlight the promise of MP hydro(bio)logy as a sensitive, cost-effective approach for integrated water management, improved flood impact assessment, and the formulation of urban planning strategies tailored to mitigate environmental risks in rapidly changing catchments.

受人类活动和土地利用影响的城市径流是微塑料的主要来源，导致河流、地下水和沿海系统受到污染。由于其来源多样和动态的运输过程，了解城市径流中的MP来源、可变性和行为仍然具有挑战性。洪水事件加速了MPs的动员，在集水区和生态系统中重新分配颗粒。破碎、老化和滞留等过程改变了MPs的大小、形状和表面性质，影响了它们在不同环境中的运输、积累和相互作用。这篇观点文章探讨了MP分析的潜力，以评估城市化景观中地表水-地下水相互作用的程度和途径，重点是洪水影响。该研究进一步强调了MPs与其他污染物的共存以及它们对地下水的潜在渗透。通过对洪水期间和之后微塑料污染物负荷、组成和运输的分析，该观点证明了它们作为洪水发生标志和评估城市发展改变的水文连通性工具的双重功能。这些发现突出了MP水电（生物）学作为一种敏感的、具有成本效益的综合水资源管理、改进洪水影响评估和制定城市规划战略以减轻快速变化的集水区环境风险的前景。

Desalination addresses freshwater scarcity, but hypersaline brine discharge raises ecological and health concerns. This review synthesizes 15 years of research on desalination brine impacts. Key stressors, high salinity, temperature, alkalinity, and metals, degrade water quality, biodiversity, and ecological balance. Effects include 40% plankton loss and 25–30% seagrass decline near outfalls. Elevated ions and residual chemicals disrupt microbes, fostering pathogens and disease. Regulatory frameworks remain fragmented. Advances in AI modeling and resource recovery offer mitigation, yet knowledge gaps persist on cumulative and synergistic impacts. Sustainable desalination requires integrated monitoring, AI-based management, and harmonized global regulations for ecosystem protection.

海水淡化解决了淡水短缺问题，但高盐盐水排放引发了生态和健康问题。本文综述了15年来海水淡化对盐水影响的研究。高盐度、高温度、高碱度和高金属等关键压力源会降低水质、生物多样性和生态平衡。影响包括40%的浮游生物损失和25-30%的海草在排水口附近减少。升高的离子和残留的化学物质破坏微生物，滋生病原体和疾病。监管框架仍然支离破碎。人工智能建模和资源恢复方面的进步提供了缓解措施，但在累积和协同影响方面的知识差距仍然存在。可持续的海水淡化需要综合监测、基于人工智能的管理和协调的全球生态系统保护法规。

Continuous accumulation of plastic litter in terrestrial ecosystems acts as a major pathway for the macroplastics (MaPs) and microplastics (MiPs) contamination into marine environment. This review synthesizes current knowledge on the sources, fate, and transport of plastic litter within soil–plant systems. It also presents a novel synthesis that connects plastic litter–induced modifications in soil properties and nutrient dynamics with physiological stress, root distortion, and reduced photosynthetic performance in plants. It was found that MaPs primarily affect soil structure by blocking pores and disrupting aggregation, whereas MiP impairs seed germination, nutrient uptake, photosynthesis, and redox imbalance via oxidative stress and leachates of toxic additives. Evidence indicates the uptake and vascular translocation of MiP in edible tissues causes potential risks to food chain. Finally, future research directions were proposed on soil remediation strategies, assessing long-term impact of MiPs and nanoplastics on plant genetic cycle.

陆地生态系统中塑料垃圾的持续积累是巨塑料（MaPs）和微塑料（MiPs）污染海洋环境的主要途径。本文综述了目前关于土壤-植物系统中塑料凋落物的来源、命运和运输的知识。它还提出了一种新的综合方法，将塑料凋落物引起的土壤性质和营养动态的改变与植物的生理胁迫、根系扭曲和光合性能降低联系起来。研究发现，map主要通过堵塞气孔和破坏团聚来影响土壤结构，而MiP则通过氧化应激和有毒添加剂的渗滤液来影响种子萌发、养分吸收、光合作用和氧化还原失衡。有证据表明，MiP在可食用组织中的摄取和血管易位会对食物链造成潜在风险。最后，提出了未来土壤修复策略的研究方向，评估了MiPs和纳米塑料对植物遗传循环的长期影响。
