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。

The increasing use of traditional agricultural plastic mulch films (PMs) has raised significant environmental concerns, prompting the search for sustainable alternatives. Soil-biodegradable mulch films (BDMs) are often proposed as eco-friendly replacements; however, their widespread adoption remains contentious. This review employs a comparative life cycle assessment perspective to evaluate the environmental impact of PMs and BDMs across their production, use, and end-of-life stages, providing strategies to mitigate their impact on agroecosystems. BDMs generally exhibit lower energy use and greenhouse gas emissions than PMs but contribute to greater land-use demands. Reported eutrophication and acidification potentials are less consistent, varying based on feedstock types and the scope of assessment of BDM, as well as the end-of-life management of PM. The environmental burden of both mulch types is influenced by the life cycle stage, polymer composition, farming practices, additives, film thickness, and local climatic conditions. The manufacturing stage is a major contributor to energy use and greenhouse gas emissions for both PMs and BDMs, despite their shared benefits of increasing crop yields. However, post-use impacts are more pronounced for PMs, driven by end-of-life strategy and adsorbed waste content. While starch-based BDMs offer a more sustainable alternative to PMs, uncertainties regarding the residence time of BDM residues in soil (albeit shorter than PM residues) and their effects on soil health, coupled with higher production costs, impede widespread adoption. For BDM end-of-life, soil biodegradation is recommended. Energy and material recovery options are crucial for PM end-of-life, with mechanical recycling preferred, although it requires addressing eutrophication and human toxicity. This review discusses these complexities within specific contexts and provides actionable insights to guide the sustainable integration of mulch films into agricultural practices.

越来越多地使用传统农用塑料地膜（pm）引起了严重的环境问题，促使人们寻找可持续的替代品。土壤可生物降解地膜（bdm）经常被提议作为生态友好的替代品；然而，它们的广泛采用仍然存在争议。本综述采用比较生命周期评估的观点来评估pmms和bdm在其生产、使用和生命终止阶段的环境影响，并提出减轻其对农业生态系统影响的策略。与pm相比，bdm的能源使用和温室气体排放通常较低，但造成了更大的土地使用需求。报告的富营养化和酸化潜力不太一致，根据原料类型和BDM评估范围以及PM的寿命结束管理而有所不同。两种覆膜类型的环境负担受生命周期阶段、聚合物组成、耕作方式、添加剂、薄膜厚度和当地气候条件的影响。制造阶段是pm和bdm的能源消耗和温室气体排放的主要贡献者，尽管它们可以共同提高作物产量。然而，pm的使用后影响更为明显，这是由寿命终止策略和吸附废物含量驱动的。虽然淀粉基BDM提供了比PM更可持续的替代品，但BDM残留物在土壤中的停留时间（尽管比PM残留物短）及其对土壤健康的影响的不确定性，加上较高的生产成本，阻碍了BDM的广泛采用。对于BDM的报废，建议采用土壤生物降解。能源和材料回收方案对于PM的报废至关重要，机械回收是首选，尽管它需要解决富营养化和人体毒性问题。本综述在具体背景下讨论了这些复杂性，并提供了可操作的见解，以指导地膜与农业实践的可持续整合。

Microplastics have emerged as pervasive environmental pollutants, posing significant risks to both terrestrial and aquatic ecosystems worldwide. Current remediation strategies—including physical, chemical, and microbial methods—are inadequate for large-scale, in situ removal of microplastics, highlighting the urgent need for alternative solutions. Phytoremediation, an eco-friendly and cost-effective technology, holds promise in addressing these challenges, though its application to microplastic pollution remains underexplored. Here we show the capacity of Eichhornia crassipes (water hyacinth), a fast-growing, floating aquatic plant, to remove microplastics from contaminated water. Our results show that within 48 h, water hyacinth achieved removal efficiencies of 55.3 %, 69.1 %, and 68.8 % for 0.5, 1, and 2 μm polystyrene particles, respectively, with root adsorption identified as the primary mechanism. Fluorescence microscopy revealed that the extremely large and abundant root caps, featuring a total surface area exceeding 150,000 mm² per plant, serve as the principal sites for the entrapment of microplastics. Furthermore, a unique “vascular ring” structure within the stem prevents the translocation of microplastics to aerial tissues, safeguarding leaves for potential downstream applications. This study offers the first microstructural insight into the mechanisms underpinning water hyacinth's exceptional microplastic adsorption capacity and resilience, providing a promising framework for developing phytoremediation strategies to mitigate microplastic pollution in aquatic ecosystems.

微塑料已成为普遍存在的环境污染物，对全球陆地和水生生态系统构成重大风险。目前的修复策略——包括物理、化学和微生物方法——不足以大规模就地去除微塑料，因此迫切需要替代解决方案。植物修复技术是一种生态友好且具有成本效益的技术，有望解决这些挑战，尽管其在微塑料污染中的应用仍未得到充分探索。在这里，我们展示了水葫芦（水葫芦），一种快速生长的漂浮水生植物，从污染的水中去除微塑料的能力。结果表明，在48 h内，水葫芦对0.5 μm、1 μm和2 μm聚苯乙烯颗粒的去除率分别为55.3%、69.1%和68.8%，其中根吸附是主要机理。荧光显微镜显示，极其巨大和丰富的根冠，其总表面积超过150000平方毫米，是微塑料捕获的主要场所。此外，茎内独特的“维管环”结构可以防止微塑料转移到空中组织，保护叶片的潜在下游应用。该研究首次从微观结构上深入了解水葫芦具有优异的微塑料吸附能力和弹性的机制，为开发植物修复策略以减轻水生生态系统中的微塑料污染提供了一个有希望的框架。

Precise identification and categorization of building materials are essential for informing strategies related to embodied carbon reduction, building retrofitting, and circularity in urban environments. However, existing building material databases are typically limited to individual projects or specific geographic areas, offering only approximate assessments. Acquiring large-scale and precise material data is hindered by inadequate records and financial constraints. Here, we introduce a novel automated framework that harnesses recent advances in sensing technology and deep learning to identify roof and facade materials using remote sensing data and Google Street View imagery. The model was initially trained and validated on Odense's comprehensive dataset and then extended to characterize building materials across Danish urban landscapes, including Copenhagen, Aarhus, and Aalborg. Our approach demonstrates the model's scalability and adaptability to different geographic contexts and architectural styles, providing high-resolution insights into material distribution across diverse building types and cities. These findings are pivotal for informing sustainable urban planning, revising building codes to lower carbon emissions, and optimizing retrofitting efforts to meet contemporary standards for energy efficiency and emission reductions.

建筑材料的精确识别和分类对于城市环境中碳减排、建筑改造和循环相关的策略至关重要。然而，现有的建筑材料数据库通常仅限于个别项目或特定的地理区域，只能提供大致的评估。不充分的记录和财政限制阻碍了获取大规模和精确的材料数据。在这里，我们介绍了一个新的自动化框架，利用遥感数据和谷歌街景图像，利用最新的传感技术和深度学习来识别屋顶和立面材料。该模型最初在欧登塞的综合数据集上进行了训练和验证，然后扩展到丹麦城市景观的建筑材料特征，包括哥本哈根、奥胡斯和奥尔堡。我们的方法展示了模型的可扩展性和对不同地理环境和建筑风格的适应性，为不同建筑类型和城市的材料分布提供了高分辨率的见解。这些发现对于为可持续城市规划提供信息、修订建筑规范以降低碳排放、优化改造工作以满足当代能效和减排标准至关重要。

Cities play a pivotal role in global decarbonization, acting as a critical driver of carbon emissions. Accurately allocating carbon mitigation responsibility (CMR) is essential for designing effective and equitable climate policies. How cities manage carbon leakage across boundaries through supply chains and implement plan of increasing forest carbon sinks are important components for designing a fair and inclusive CMR. However, the combined impact of trade-related carbon leakage and forest carbon sinks on CMR allocation remains poorly understood. Here, we develop an integrated CMR allocation framework that accounts for both carbon leakage and variation of forest carbon offsets. When applied to the cities within the Guangdong–Hong Kong–Macao Greater Bay Area in China, it becomes evident that the inclusion of carbon leakage results in substantial alterations in mitigation quotas. Adjustments are observed to vary between ±10 % and 50 % across these cities from 2005 to 2020, a trend that is anticipated to continue until 2035. The redistribution of outsourced emissions through supply chains alleviates the mitigation burden on producer cities by 20–30 %. Additionally, accounting for carbon sinks substantially influences CMR allocation, particularly in forest-rich cities, which may see their carbon budgets increase by up to 10 %. Under an enhanced climate policy scenario, the growth rate of total mitigation quotas from 2025 to 2035 is projected to decrease by 40 % compared to a business-as-usual trajectory, reducing the burden on major producer cities. Our proposed CMR framework provides a robust basis for incentivizing coordinated mitigation efforts, promoting decarbonization in supply chains and enhancement of urban carbon sink capacities.

城市在全球脱碳中发挥着关键作用，是碳排放的关键驱动因素。准确分配碳减排责任（CMR）对于设计有效和公平的气候政策至关重要。城市如何通过供应链管理跨界碳泄漏，实施增加森林碳汇的计划，是设计公平、包容的碳排放管理体系的重要组成部分。然而，与贸易有关的碳泄漏和森林碳汇对CMR分配的综合影响仍然知之甚少。在这里，我们开发了一个综合的CMR分配框架，该框架考虑了碳泄漏和森林碳抵消的变化。当应用于中国粤港澳大湾区内的城市时，很明显，碳泄漏的纳入导致了减排配额的实质性变化。从2005年到2020年，这些城市的调整幅度在±10%到50%之间，预计这一趋势将持续到2035年。通过供应链重新分配外包排放，可将生产城市的减排负担减轻20 - 30%。此外，考虑碳汇对CMR分配产生重大影响，特别是在森林资源丰富的城市，这些城市的碳预算可能会增加10%。在强化的气候政策情景下，预计2025年至2035年的总缓解配额增长率将比一切照旧的轨迹下降40%，从而减轻主要生产城市的负担。我们提出的CMR框架为激励协调的减缓努力、促进供应链脱碳和增强城市碳汇能力提供了坚实的基础。

The parameters of activatedg sludge are crucial for the daily operation of wastewater treatment plants (WWTPs). In particular, mixed liquor suspended solids (MLSS) and apparent viscosity provide metrics for the biomass and rheological properties of activated sludge. Traditional methods for determining these parameters are time-consuming, require separate measurements for each index, and fail to provide real-time data for future ‘smart’ WWTPs. Here we show a real-time online microscopic image data analysis system that quantitatively identifies MLSS and apparent viscosity. Microscopic videos of activated sludge are captured in lab-scale sequencing batch reactors under chemical oxygen demand shock, yielding 41482 high-quality images. The Xception convolutional neural network architecture is used to establish both qualitative and quantitative correlations between these microscopic images and MLSS/apparent viscosity. The accuracies of qualitative identification for MLSS and apparent viscosity are both higher than 97%, and the quantitative correlation coefficients are 0.95 and 0.96, respectively. This quantitative correlation between microscopic images of activated sludge and its physical parameters, specifically MLSS and apparent viscosity, provides a basis for real-time online measurements of activated sludge parameters in WWTPs.

活性污泥的参数对污水处理厂的日常运行至关重要。特别是，混合液悬浮固体（MLSS）和表观粘度为活性污泥的生物量和流变特性提供了指标。确定这些参数的传统方法非常耗时，需要对每个指标进行单独测量，并且无法为未来的“智能”污水处理厂提供实时数据。在这里，我们展示了一个实时在线显微图像数据分析系统，可以定量识别MLSS和表观粘度。在化学需氧量冲击下，在实验室规模的顺序间歇式反应器中捕获活性污泥的显微视频，产生41482张高质量图像。Xception卷积神经网络架构用于建立这些显微图像与MLSS/表观粘度之间的定性和定量相关性。MLSS和表观黏度的定性鉴别准确率均大于97%，定量相关系数分别为0.95和0.96。活性污泥的显微图像与其物理参数（特别是MLSS和表观粘度）之间的定量相关性，为污水处理厂活性污泥参数的实时在线测量提供了基础。
