The widespread and indiscriminate use of biocides poses significant threats to global health, socioeconomic development, and environmental sustainability by accelerating antibiotic resistance. Bacterial resistance development is highly complex and influenced significantly by environmental factors. Increased biocide usage in households, agriculture, livestock farming, industrial settings, and hospitals produces persistent chemical residues that pollute soil and aquatic environments. Such contaminants contribute to the selection and proliferation of resistant bacteria and antimicrobial resistance genes (ARGs), facilitating their dissemination among humans, animals, and ecosystems. In this review, we conduct a critical assessment of four significant issues pertaining to this topic. Specifically, (i) the role of biocides in exerting selective pressure within the environmental resistome, thereby promoting the proliferation of resistant microbial populations and contributing to the global spread of antimicrobial resistance genes (ARGs); (ii) the role of biocides in triggering transient phenotypic adaptations in bacteria, including efflux pump overexpression, membrane alterations, and reduced porin expression, which often result in cross-resistance to multiple antibiotics; (iii) the capacity of biocides to disrupt bacteria and make the genetic content accessible, releasing DNA into the environment that remains intact under certain conditions, facilitating horizontal gene transfer and the spread of resistance determinants; (iv) the capacity of biocides to disrupt bacterial cells, releasing intact DNA into the environment and enhancing horizontal gene transfer of resistance determinants; and (iv) the selective interactions between biocides and bacterial biofilms in the environment, strengthening biofilm cohesion, inducing resistance mechanisms, and creating reservoirs for resistant microorganisms and ARG dissemination. Collectively, this review highlights the critical environmental and public health implications of biocide use, emphasizing an urgent need for strategic interventions to mitigate their role in antibiotic resistance proliferation.

杀菌剂的广泛和滥用加速了抗生素耐药性，对全球健康、社会经济发展和环境可持续性构成重大威胁。细菌耐药性的发展非常复杂，受环境因素的影响很大。在家庭、农业、畜牧业、工业环境和医院中越来越多地使用杀菌剂，产生持久性化学残留物，污染土壤和水生环境。这些污染物有助于耐药细菌和抗微生物药物耐药性基因（ARGs）的选择和增殖，促进它们在人类、动物和生态系统中传播。在这篇综述中，我们对与该主题有关的四个重要问题进行了批判性评估。具体而言，(i)杀菌剂在环境抗性组内施加选择压力的作用，从而促进耐药微生物种群的增殖，并促进抗微生物药物耐药性基因（ARGs）的全球传播；（ii）杀菌剂在触发细菌短暂表型适应中的作用，包括外排泵过表达、膜改变和孔蛋白表达减少，这通常导致对多种抗生素的交叉抗性；（iii）杀菌剂破坏细菌和使遗传内容可接近的能力，将DNA释放到在某些条件下保持完整的环境中，促进水平基因转移和抗性决定因素的传播；（iv）杀菌剂破坏细菌细胞的能力，将完整的DNA释放到环境中，并加强抗性决定因素的水平基因转移；（iv）杀菌剂与环境中细菌生物膜之间的选择性相互作用，加强生物膜凝聚力，诱导抗性机制，并为耐药微生物和ARG传播创造储存库。总的来说，这篇综述强调了使用杀菌剂对环境和公共卫生的重要影响，强调迫切需要采取战略性干预措施，以减轻其在抗生素耐药性扩散中的作用。

Wastewater treatment plants significantly contribute to greenhouse gas emissions, including nitrous oxide (N₂O), carbon dioxide (CO₂), and methane (CH₄). Current methods to measure these emissions typically target specific molecular compounds, providing limited scope and potentially incomplete emissions profiles. Here, we show an innovative ultra-broadband coherent open-path spectroscopy (COPS) system capable of simultaneously monitoring multiple greenhouse gases. This novel approach combines Fourier transform spectroscopy with a coherent, ultra-broadband mid-infrared light source spanning 2–11.5 μm at approximately 3 W power. Positioned above an aeration tank, the COPS system selectively detected absorption signatures for CH₄, CO₂, N₂O, ammonia (NH₃), carbon monoxide (CO), and water vapor (H₂O), enabling real-time, path-integrated concentration measurements with a temporal resolution of 40 s. Elevated concentrations of CH₄ and CO₂ were clearly identified within emission plumes traversing the beam path above the aeration tank. Additionally, CH₄ emission patterns closely tracked variations in ammonium loading from incoming wastewater, whereas CO₂ emissions correlated strongly with oxygen concentrations introduced during aeration. Measurements of N₂O, NH₃, and CO were stable and aligned closely with traditional point-based measurements from commercial gas analyzers. Our findings demonstrate that COPS offers a robust, comprehensive solution for the simultaneous real-time monitoring of multiple gases in complex and heterogeneous emission environments. This capability significantly enhances atmospheric and industrial emission assessments, potentially transforming the approach to emissions quantification and environmental management.

污水处理厂对温室气体排放有很大贡献，包括一氧化二氮（N2O）、二氧化碳（CO2）和甲烷（CH4）。目前测量这些排放的方法通常针对特定的分子化合物，提供有限的范围和可能不完整的排放概况。在这里，我们展示了一种创新的超宽带相干开放路径光谱（COPS）系统，能够同时监测多种温室气体。这种新颖的方法结合了傅里叶变换光谱与相干的超宽带中红外光源，光源跨度为2-11.5 μm，功率约为3w。位于曝气罐上方的COPS系统可以选择性地检测CH4、CO2、N2O、氨（NH3）、一氧化碳（CO）和水蒸气（H2O）的吸收特征，实现实时、路径集成的浓度测量，时间分辨率为40 s。在穿过曝气池上方光束路径的排放羽流中，CH4和CO2浓度明显升高。此外，CH4排放模式密切跟踪入水氨负荷的变化，而CO2排放与曝气过程中引入的氧浓度密切相关。N2O、NH3和CO的测量结果是稳定的，与传统的基于点的商业气体分析仪测量结果非常接近。我们的研究结果表明，COPS为在复杂和异质排放环境中同时实时监测多种气体提供了一个强大、全面的解决方案。这种能力大大加强了大气和工业排放评估，可能改变排放量化和环境管理的方法。

Soil bacterial and fungal communities play fundamental roles in biogeochemical cycles and ecosystem stability. Urbanization alters soil properties and microbial habitats, driving shifts in community composition, yet the divergent responses of bacteria and fungi and their ecological consequences remain inadequately understood. To elucidate these differential responses, we investigated soil bacterial and fungal communities along an urbanization gradient, ranging from undisturbed reference forests to urban parks, across three distinct climatic regions. To capture different disturbance intensities, urban parks were classified by tree age into old parks (>60-year-old trees) and young parks (10–20-year-old trees). Climate had a strong influence on soil microbiota, yet urbanization still significantly altered both bacterial and fungal communities in all regions. Urban disturbances homogenized soil microbial communities: average similarity among bacterial communities increased from ∼79 % in forests to ∼85 % in young urban parks, indicating substantial homogenization, whereas fungal communities showed little homogenization. Urbanization also homogenized microbial functional traits, with a greater reduction in trait dissimilarity for bacteria than for fungi. Bacterial communities exhibited high adjustability to urban conditions, dominated by generalist taxa (∼90 %), whereas fungal communities consisted mostly of specialists (∼83 %). Despite these asynchronous responses—bacteria adjusting and homogenizing more than fungi—overlapping functional traits between bacteria and fungi help maintain functional resilience in urban ecosystems.

土壤细菌和真菌群落在生物地球化学循环和生态系统稳定中起着重要作用。城市化改变了土壤性质和微生物栖息地，推动了群落组成的变化，但细菌和真菌的不同反应及其生态后果仍未得到充分了解。为了阐明这些不同的反应，我们研究了沿着城市化梯度的土壤细菌和真菌群落，范围从未受干扰的参考森林到城市公园，跨越三个不同的气候区域。为了捕捉不同的干扰强度，将城市公园按树龄划分为老公园（60年树龄）和幼公园（10 - 20年树龄）。气候对土壤微生物群有强烈的影响，但城市化仍显著改变了所有地区的细菌和真菌群落。城市扰动使土壤微生物群落均质化：细菌群落的平均相似性从森林的~ 79%增加到年轻的城市公园的~ 85%，表明存在实质性的均质化，而真菌群落几乎没有均质化。城市化也使微生物功能特征同质化，细菌的特征差异比真菌的特征差异减少得更多。细菌群落对城市条件表现出高度的适应性，以通才类群为主（约90%），而真菌群落主要由专才类群组成（约83%）。尽管存在这些不同步的反应——细菌调节和同质化比真菌更多——细菌和真菌之间重叠的功能特征有助于维持城市生态系统的功能弹性。

The global push for carbon neutrality highlights the need for rigorous assessments of whether national efforts align with stated targets. However, existing evaluations often prioritize commitments over tangible progress, lacking comprehensive and transparent metrics. To bridge this gap, we develop a multidimensional indicator system that evaluates targets, policies, actions, and effectiveness across key areas, including policy implementation, technology deployment, financial investment, and international cooperation. While 151 countries have pledged carbon neutrality—19 of which are developing nations that made commitments in 2024—implementation remains uneven. Only 72 countries have established complete policy frameworks, and advanced low-carbon technologies are concentrated in a handful of nations. Current trends indicate that global renewable energy capacity will reach just 2.7 times its 2022 level by 2030, falling short of the tripling target. Moreover, the global median action score in 2024 stands at only 25—far below the target of 65—highlighting the urgency for stronger efforts. Our findings reveal a significant gap between ambition and action, with renewable energy deployment lagging behind expectations. To accelerate progress, enhanced global cooperation, increased investment, and fewer barriers to technology diffusion are crucial. This study underscores the need for more implementation-focused tracking to ensure carbon neutrality commitments translate into measurable outcomes.

全球对碳中和的推动凸显了对各国努力是否符合既定目标进行严格评估的必要性。然而，现有的评价往往将承诺置于实际进展之上，缺乏全面和透明的衡量标准。为了弥补这一差距，我们制定了一个多维指标体系，对政策实施、技术部署、金融投资和国际合作等关键领域的目标、政策、行动和有效性进行评估。尽管151个国家已经承诺实现碳中和，其中19个是发展中国家，并在2024年做出了承诺，但实施情况仍然参差不齐。只有72个国家建立了完整的政策框架，先进的低碳技术集中在少数几个国家。目前的趋势表明，到2030年，全球可再生能源容量将仅达到2022年水平的2.7倍，达不到翻三番的目标。此外，到2024年，全球行动得分中位数仅为25分，远低于65分的目标，这凸显了加强努力的紧迫性。我们的研究结果揭示了雄心与行动之间的巨大差距，可再生能源的部署落后于预期。为加快进展，加强全球合作、增加投资和减少技术传播障碍至关重要。这项研究强调，需要更多以实施为重点的跟踪，以确保碳中和承诺转化为可衡量的成果。

Climate change is driving unprecedented transformations in aquatic ecosystems, where microorganisms play a fundamental role in maintaining ecological balance and human health security. Rising water temperatures, pollution intensification, and extreme weather events are driving significant shifts in microbial community structures. These changes facilitate the proliferation of pathogenic microorganisms such as Vibrio cholerae and harmful algae like cyanobacteria, which thrive in warmer, nutrient-enriched environments. The resulting harmful algal blooms release potent toxins, such as microcystins, that contaminate drinking water and food supplies, leading to severe health impacts, including liver diseases and carcinogenesis. Furthermore, antibiotic resistance genes are spreading more rapidly due to climate-induced stressors, increasing the prevalence of antimicrobial-resistant pathogens and compounding the challenges for global health systems. This discussion article demonstrates that climate change influences aquatic microbial ecosystems through interconnected mechanisms, including shifts in gene transfer networks, alterations in microbial metabolism, and ecological feedback loops, ultimately increasing waterborne disease risks and antimicrobial resistance. Specific solutions are proposed, such as advancing wastewater treatment technologies to address climate-induced pollution, establishing global microbial monitoring networks leveraging remote sensing and molecular tools, and implementing early warning systems for waterborne disease outbreaks. Additionally, the discussion article emphasizes the critical role of international cooperation in funding and capacity-building efforts, particularly in developing regions with fragile infrastructures. By highlighting these pressing challenges and proposing actionable strategies, this research underscores the urgent need for integrated approaches to safeguard water resources, mitigate microbial hazards, and enhance public health resilience in an era of accelerating climate change.

气候变化正在推动水生生态系统发生前所未有的变化，微生物在维持生态平衡和人类健康安全方面发挥着根本作用。水温上升、污染加剧和极端天气事件正在推动微生物群落结构的重大变化。这些变化促进了霍乱弧菌等病原微生物和蓝藻等有害藻类的繁殖，它们在温暖、营养丰富的环境中茁壮成长。由此产生的有害藻华释放出强效毒素，如微囊藻毒素，污染饮用水和食物供应，导致严重的健康影响，包括肝病和致癌。此外，由于气候引起的压力源，抗生素耐药基因正在更快地传播，增加了抗微生物药物耐药性病原体的流行，并加剧了全球卫生系统面临的挑战。这篇讨论文章表明，气候变化通过相互关联的机制影响水生微生物生态系统，包括基因转移网络的改变、微生物代谢的改变和生态反馈回路，最终增加了水传播疾病的风险和抗菌素耐药性。提出了具体的解决方案，例如推进废水处理技术以应对气候引起的污染，利用遥感和分子工具建立全球微生物监测网络，以及实施水传播疾病暴发的早期预警系统。此外，讨论文章强调了国际合作在筹资和能力建设方面的关键作用，特别是在基础设施脆弱的发展中区域。通过强调这些紧迫的挑战并提出可行的战略，本研究强调了在加速气候变化的时代，迫切需要采取综合方法来保护水资源，减轻微生物危害，并增强公共卫生抵御能力。

Effective water management in large river basins requires a comprehensive understanding of policy effectiveness and regulatory frameworks. However, quantitative assessments of water-related policies remain limited. Here, we propose a novel quantitative framework for evaluating water policies in large river basins, providing an intuitive and systematic approach for decision-makers. Using the Yellow River Basin—the second-largest river basin in China—as a case study, we constructed a database of 1271 water-related policies spanning 68 cities. We assessed the completeness of nine representative policies, identifying key gaps in water environment governance. To evaluate management effectiveness, we developed a system integrating two key subsystems: water resource utilization and water environment treatment, incorporating climatic, economic, and industrial factors. Our findings reveal that water environment governance policies were more effective than those targeting water resource utilization, though their impact was delayed by one to two years. Furthermore, a risk-based analysis pinpointed critical water management challenges in each city, offering actionable insights for policy optimization. This framework provides a robust and scalable approach for assessing the effectiveness of complex water policies in large river basins, with global applicability for improving water governance.

大型流域的有效水资源管理需要对政策有效性和监管框架有全面的了解。然而，与水有关的政策的定量评估仍然有限。在此，我们提出了一个新的定量框架来评估大流域的水政策，为决策者提供了一个直观和系统的方法。以中国第二大河流黄河流域为例，构建了一个涵盖68个城市的1271项与水相关政策的数据库。我们评估了九项代表性政策的完整性，确定了水环境治理方面的关键差距。为了评估管理的有效性，我们开发了一个系统，集成了水资源利用和水环境处理两个关键子系统，结合了气候、经济和工业因素。研究结果表明，中国的水环境治理政策比以水资源利用为目标的政策更有效，但其影响要延迟一到两年。此外，基于风险的分析明确了每个城市的关键水管理挑战，为政策优化提供了可行的见解。该框架为评估大型河流流域复杂水政策的有效性提供了一种强有力的、可扩展的方法，对改善水治理具有全球适用性。

Using the Yellow River Basin—the second-largest river basin in China—as a case study, we constructed a database of 1271 water-related policies spanning 68 cities. We assessed the completeness of nine representative policies, identifying key gaps in water environment governance. To evaluate management effectiveness, we developed a system integrating two key subsystems: water resource utilization and water environment treatment, incorporating climatic, economic, and industrial factors. Our findings reveal that water environment governance policies were more effective than those targeting water resource utilization, though their impact was delayed by one to two years. Furthermore, a risk-based analysis pinpointed critical water management challenges in each city, offering actionable insights for policy optimization. This framework provides a robust and scalable approach for assessing the effectiveness of complex water policies in large river basins, with global applicability for improving water governance.</div></div>","PeriodicalId":34434,"journal":{"name":"Environmental Science and Ecotechnology","volume":"24 ","pages":"Article 100537"},"PeriodicalIF":14.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental protection policies (EPPs) play a pivotal role in advancing sustainable development and maintaining ecological balance by establishing clear directives and standards. However, a comprehensive methodology to evaluate the effectiveness of these policies remains underdeveloped. Here, we employ a difference-in-differences (DID) approach to assess the effectiveness of EPPs, using the implementation of the Resident Work (RW) policy as a quasi-natural experiment. Drawing on urban-level panel data from the Yangtze River Basin between 2016 and 2021, we demonstrate that the DID model robustly evaluates the RW policy's impact on water quality improvement. Cities that adopted the RW policy experienced a 0.0098 reduction in water pollution compared to non-adopting cities. A dynamic analysis revealed progressive water quality improvements over time, with stronger effects observed in economically disadvantaged cities. Furthermore, higher policy evaluation scores correlated with greater improvements in water quality. This study highlights the utility of the DID model in quantifying EPP effectiveness and offers a scalable framework for policy evaluation in environmental management.

环境保护政策通过制定明确的指令和标准，在促进可持续发展和维护生态平衡方面发挥着关键作用。然而，评价这些政策有效性的综合方法仍然不发达。在这里，我们采用差异中差异（DID）方法来评估epp的有效性，并将常驻工作（RW）政策的实施作为准自然实验。利用2016 - 2021年长江流域城市层面的面板数据，我们证明DID模型对节水政策对水质改善的影响进行了稳健评估。采用RW政策的城市与未采用政策的城市相比，水污染减少了0.0098。一项动态分析显示，随着时间的推移，水质逐渐改善，在经济落后的城市，效果更明显。此外，较高的政策评价分数与水质的较大改善相关。本研究强调了DID模型在量化环境保护计划有效性方面的效用，并为环境管理中的政策评估提供了一个可扩展的框架。

The global production and use of antimicrobial chemicals surged during and after the COVID-19 pandemic, yet their developmental toxicity in aquatic organisms at environmentally relevant concentrations remains poorly understood. Here, we investigate and compare the developmental effects of two restricted antimicrobial chemicals—triclosan (TCS) and triclocarban (TCC)—and three alternative antimicrobials—benzalkonium chloride (BAC), benzethonium chloride (BEC), and chloroxylenol (CX)—on zebrafish embryos (Danio rerio) at concentrations of 0.4, 4, and 40 μg L⁻¹. We find that BAC induces the most severe reduction in hatching rates, followed by TCS, TCC, BEC, and CX. BAC also exhibits the strongest inhibition of heart rate, with toxicity levels comparable to those of TCS and TCC. All tested chemicals, except CX, cause significant teratogenic effects. Transcriptomic analysis reveals substantial disruptions in immune-related coagulation cascades and mitogen-activated protein kinase signaling pathways. Further validation via protein-protein interaction network analysis and real-time quantitative polymerase chain reaction confirms that altered expression of key hub genes in these pathways impacts bone and heart development, as well as immune system function, potentially driving developmental toxicity. This study provides the first systematic comparison of developmental toxicity among currently used antimicrobials at environmentally relevant concentrations, revealing that the alternative antimicrobial BAC poses greater developmental risks than the banned TCS and TCC. These findings raise concerns about the safety of BAC as a widespread substitute and highlight the necessity for more rigorous environmental risk assessments of alternative antimicrobials before their large-scale application.

在2019冠状病毒病大流行期间和之后，全球抗微生物化学品的生产和使用激增，但它们在环境相关浓度下对水生生物的发育毒性仍知之甚少。在这里，我们研究并比较了两种限制性抗菌剂三氯生（TCS）和三氯卡班（TCC）以及三种替代抗菌剂苯扎氯铵（BAC）、苯扎氯铵（BEC）和氯二酚（CX）在0.4、4和40 μg L−1浓度下对斑马鱼胚胎（Danio rerio）的发育影响。我们发现BAC诱导孵化率降低最严重，其次是TCS， TCC， BEC和CX。BAC对心率的抑制作用也最强，毒性水平与TCS和TCC相当。除CX外，所有测试的化学物质都有显著的致畸作用。转录组学分析揭示了免疫相关凝血级联和丝裂原激活的蛋白激酶信号通路的实质性破坏。通过蛋白质-蛋白质相互作用网络分析和实时定量聚合酶链反应进一步验证，这些途径中关键枢纽基因表达的改变会影响骨骼和心脏发育，以及免疫系统功能，潜在地驱动发育毒性。本研究首次系统比较了当前使用的抗菌剂在环境相关浓度下的发育毒性，揭示了替代抗菌剂BAC比禁用的TCS和TCC具有更大的发育风险。这些发现引起了人们对BAC作为广泛替代品的安全性的关注，并强调了在大规模应用替代抗菌剂之前对其进行更严格的环境风险评估的必要性。

The sustainable treatment of hypersaline organic wastewater (HSOW) remains a significant challenge in industrial wastewater management, as conventional approaches often fail to meet stringent discharge standards and low-carbon sustainability targets. Halotolerant and halophilic microbial strains offer promising solutions, yet their application is hindered by limited stress resistance, thus hindering effective treatment and achieving near-zero liquid discharge. In this review, we systematically examine endogenous strategies, such as microbial mutualism and genetic engineering, alongside exogenous approaches, including functional materials, electrical and magnetic stimulation, and 3D bioprinting, to improve microbial resilience in hypersaline environments. Furthermore, we propose an integrated treatment framework that combines physicochemical and biochemical processes, leveraging biological detoxification and biological desalination to enhance the treatment of HSOW while minimizing environmental impact and carbon emissions. By advancing the understanding of microbial stress adaptation and optimization strategies, this review provides critical insights into the development of sustainable, low-carbon wastewater treatment solutions.

高盐有机废水（HSOW）的可持续处理仍然是工业废水管理中的一个重大挑战，因为传统方法往往无法满足严格的排放标准和低碳可持续发展目标。耐盐和嗜盐微生物菌株提供了有前途的解决方案，但它们的应用受到有限的抗逆性的阻碍，从而阻碍了有效的处理和实现接近零的液体排放。在这篇综述中，我们系统地研究了内源性策略，如微生物共生和基因工程，以及外源性方法，包括功能材料，电和磁刺激，以及3D生物打印，以提高高盐环境下微生物的恢复能力。此外，我们提出了一种综合处理框架，结合物理化学和生物化学过程，利用生物解毒和生物脱盐来加强对HSOW的处理，同时最大限度地减少对环境的影响和碳排放。通过促进对微生物胁迫适应和优化策略的理解，本综述为可持续、低碳废水处理解决方案的发展提供了重要见解。
