Class 1 integrons facilitate horizontal gene transfer, significantly influencing antibiotic resistance gene (ARG) dissemination within microbial communities. Wastewater treatment plants (WWTPs) are critical reservoirs of ARGs and integrons, yet the integron-mediated dynamics of ARG transfer across different WWTP types remain poorly understood. Here we show distinct ARG profiles associated with class 1 integrons in municipal and industrial WWTPs using a novel approach combining nested-like high-throughput qPCR and PacBio sequencing. Although industrial WWTPs contained higher absolute integron abundances, their relative ARG content was lower (1.27 × 107–9.59 × 107 copies/ng integron) compared to municipal WWTPs (3.72 × 107–1.98 × 108 copies/ng integron). Of the 132,084 coding sequences detected from integrons, 56.8 % encoded antibiotic resistance, with industrial plants showing lower ARG proportions, reduced ARG array diversity, and greater incorporation of non-ARG sequences. These findings suggest industrial WWTP integrons integrate a broader array of exogenous genes, reflecting adaptation to complex wastewater compositions. This work enhances our understanding of integron-driven ARG dynamics in wastewater and offers a robust strategy for environmental integron analysis.

Wastewater-treatment plants (WWTPs) enable urban water reclamation but are significant sources of greenhouse-gas (GHG) emissions. Because GHG output scales with the volume and pollutant load of influent sewage, city-wide water-use patterns offer a direct yet under-examined lever for decarbonizing WWTP operations. The feedbacks linking demand-side water conservation to plant emissions remain poorly understood, obscuring important mitigation co-benefits. Here we show a domino-effect feedback between urban water-use patterns with WWTP carbon emissions. Our analysis demonstrates that optimized water management can improve average WWTP eco-efficiency by up to 189 %, leading to an annual reduction in water consumption of 48.3 billion m3 and a decrease in GHG emissions by 1.67 million tons CO2-equivalent. Under this synergistic water-carbon management scenario, the wastewater sector could achieve carbon neutrality by 2037, seven years ahead of schedules based solely on technological advancements. Our findings present a novel and replicable framework that simultaneously addresses water scarcity and climate change. Unlike costly and slow-to-implement technological innovations, leveraging cross-sectoral synergies in water-intensive industries such as agriculture and manufacturing offers a pragmatic pathway to meeting critical carbon-reduction targets.

Organic pollutants remain a persistent threat to ecosystems and human health. In soils, humification gradually converts these compounds into stable humic substances and attenuates their toxicity, but the transformation can take decades—far too slow to match current pollution loads. In this Perspective, we argue that mature compost offers a pragmatic means to accelerate this process: it delivers partially humified intermediates that can “seed” soil humification and shorten its timescale from decades to seasons. Spectroscopic evidence shows that compost-derived humus is enriched in aromatic backbones and reactive functional groups (–COOH, –OH) that both catalyze further condensation of organic matter and immobilise pollutants through π–π stacking, hydrogen bonding and covalent coupling. By merging these catalytic and sorptive functions, compost amendments provide a scalable, low-cost route to the long-term stabilization of organic contaminants. We outline the key mechanistic questions that now need resolution—particularly the reactivity of specific intermediates in situ—to guide field trials and unlock the full potential of compost-driven accelerated humification as an environmental remediation platform.

Legacy phosphorus, accumulated from past anthropogenic activities, poses persistent and complex threats to global water quality. Despite extensive efforts to control phosphorus inputs, legacy phosphorus can persist for decades and undermine restoration goals. Emerging evidence suggests that shifts in regional development patterns profoundly reshape the dynamics and environmental risks of legacy phosphorus accumulation and mobilization. However, the mechanisms by which development pattern shifts reshape legacy phosphorus trajectories remain poorly understood. Here we show the complex pathways linking development-driven land-use changes, biogeochemical buffering capacities, and legacy phosphorus mobilization through an integrative modeling framework that couples developmental shift coefficients, anthropogenic phosphorus inventories, and riverine time-lag modeling to diagnose and predict long-term legacy phosphorus risks. Using the Songhua River as a case study, our results reveal that shifts from industrial to agricultural dominance significantly amplify legacy phosphorus accumulation by 86 times. Consequently, legacy phosphorus accounts for 65.4 %–69.9 %, surpassing current-year inputs and becoming the primary driver of riverine pollution. Furthermore, we demonstrate that development shifts systematically alter the dominant controlling factors, from fossil fuel emissions and drainage infrastructure to soil retention characteristics and agricultural practices, reshaping mitigation priorities. Our framework provides a generalizable methodology for quantifying legacy phosphorus risks under dynamic development patterns, offering immediate applications for water quality management. More broadly, this framework offers critical insights that can guide sustainable management strategies for linking evolving regional development patterns with long-term ecological restoration.

Biomanufacturing of hydrogen by acidogenic fermentation presents a promising avenue for sustainable hydrogen production; however, data on its full-scale application remain limited. Here we evaluate the performance of a 100 m3 continuous-flow stirred-tank reactor (CSTR) utilizing waste molasses and inoculated with aerobic excess sludge for hydrogen production. The reactor operated at 35 °C with a constant hydraulic retention time of 5.8 h, while the organic loading rate (OLR) was incrementally increased from 9.3 to 57.3 kg COD m−3 d−1. By day 19, stable ethanol-type fermentation was established, yielding an average of 265 m3 of hydrogen per day. Over the subsequent 72 days, the reactor maintained continuous operation, achieving an average hydrogen production rate of 282 m3 d−1 at an average OLR of 28.5 kg COD m−3 d−1. Bioaugmentation with Ethanoligenens harbinense YUAN-3 at a 0.5 % volume fraction relative to the mixed liquor volatile suspended solids further enhanced hydrogen production to an average of 348 m3 d−1. Despite fluctuations in the OLR between 17.1 and 55.2 kg COD m−3 d−1, ethanol-type fermentation persisted throughout the bioaugmentation period. These findings demonstrate the viability of full-scale acidogenic fermentation for efficient hydrogen biomanufacturing from high-strength organic wastewater.
产酸发酵生物制氢是一种很有前途的可持续制氢途径；然而，关于其全面应用的数据仍然有限。在这里，我们评估了一个100立方米的连续流搅拌槽反应器（CSTR）的性能，该反应器利用废糖蜜并接种好氧剩余污泥用于制氢。反应器运行温度为35℃，水力停留时间为5.8 h，有机负载率（OLR）由9.3 kg COD m−3 d−1逐步提高到57.3 kg COD m−3 d−1。到第19天，建立了稳定的乙醇型发酵，平均每天产生265 m3的氢气。在随后的72天里，反应器保持连续运行，平均产氢率为282 m3 d - 1，平均OLR为28.5 kg COD m - 3 d - 1。以相对于混合液挥发性悬浮物的0.5%体积分数添加乙醇寡聚烯habinense YUAN-3，进一步提高了产氢量，平均达到348 m3 d - 1。尽管OLR在17.1和55.2 kg COD m - 3 d - 1之间波动，但乙醇型发酵在整个生物增强期持续存在。这些发现证明了大规模产酸发酵从高强度有机废水中高效制氢的可行性。

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.

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 (PNECRS) 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.

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.

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 (RMSEcalibration = 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.
