The co-occurrence of microplastics and heavy metals, particularly cadmium (Cd), in terrestrial ecosystems poses a growing ecological risk, yet their combined effects on plant community functioning remain unclear. We conducted a full-factorial mesocosm experiment with four polypropylene microplastic levels (0, 0.1%, 0.5%, and 1% w/w) and two Cd treatments (0 and 10 mg·kg⁻¹) to assess species-specific and community-level responses. Measurements of soil properties, community composition, root traits, and productivity revealed that microplastic-Cd co-exposure consistently reduced community productivity, primarily through suppression of arbuscular mycorrhizal (AM) plant dominance. Root trait analyses indicated diminished intrinsic nutrient acquisition capacity, leading to greater dependence on AM symbiosis and narrowing the Levins’ ecological niche breadth of AM-associated species. Structural equation modeling identified community mycorrhization as the key mediator of productivity loss, while random forest analysis ranked the mycorrhizal index (determined by community-level mycorrhization) as the strongest predictor. Altered soil C:N:P stoichiometry and ionic conditions further emerged as critical environmental drivers constraining AM plants under co-exposure. Collectively, these findings demonstrate that microplastic-Cd interactions destabilize plant–soil symbioses and weaken community productivity by undermining AM plant dominance, underscoring the vulnerability of AM-dominated communities and the importance of integrating symbiotic strategies into ecological risk assessments.

微塑料和重金属，特别是镉（Cd）在陆地生态系统中的共存构成了越来越大的生态风险，但它们对植物群落功能的综合影响尚不清楚。我们在四种聚丙烯微塑料水平（0、0.1%、0.5%和1% w/w）和两种Cd处理（0和10 mg·kg毒血症）下进行了全因子中效实验，以评估物种特异性和社区水平的反应。土壤特性、群落组成、根系性状和生产力的测量表明，微塑料- cd共暴露持续降低群落生产力，主要是通过抑制丛枝菌根（AM）植物的优势性。根系性状分析表明，植物内在养分获取能力下降，对AM共生关系的依赖性增强，AM伴生物种的leins生态位宽度减小。结构方程模型发现群落菌根化是生产力损失的关键中介，而随机森林分析认为菌根指数（由群落水平菌根化决定）是最强的预测因子。土壤C:N:P化学计量和离子条件的改变进一步成为限制AM植物共暴露的关键环境驱动因素。综上所述，这些研究结果表明，微塑料-镉相互作用破坏了植物-土壤共生关系的稳定性，并通过破坏AM植物的优势地位来削弱群落的生产力，强调了AM优势群落的脆弱性，以及将共生策略纳入生态风险评估的重要性。

Ethylene production processes using alternative carbon sources like biomass or CO2 could have great potential for the olefins industry. Comparing the benefits and pitfalls of different process routes is challenging due to the vastly different feedstocks and key conversion technologies involved. Here, we performed an ex-ante techno-economic and environmental assessment to explore potential trade-offs of three low technology readiness level ethylene production processes. The three routes were: 1) biobased syngas fermentation to ethanol followed by ethanol dehydration, 2) direct electrochemical conversion of CO2, and 3) indirect CO2 and H2O electrolysis to form syngas followed by a Fischer-Tropsch step. This study found three main takeaways. Firstly, the biobased route significantly outperforms the direct and indirect routes in terms of techno-economic and carbon footprint performance. Secondly, the electrolyzer unit is the main factor limiting the techno-economic performance of the direct and indirect cases, reemphasizing the need for continued technological advancements and cost reductions by researchers in this domain. Finally, the indirect plant design, incorporating two electrolyzers and a Fischer-Tropsch step, is not techno-economically feasible for ethylene production, underscoring the need for further research on Fischer-Tropsch plant designs to advance the replacement of traditional fossil-based refineries.

使用生物质或二氧化碳等替代碳源的乙烯生产工艺对烯烃工业具有巨大的潜力。由于所涉及的原料和关键转化技术差异很大，比较不同工艺路线的优点和缺陷是具有挑战性的。在这里，我们进行了事前技术经济和环境评估，以探索三种低技术准备水平的乙烯生产工艺的潜在权衡。这三种途径分别是：1)生物合成气发酵制乙醇，然后乙醇脱水；2)CO2直接电化学转化；3)CO2和H2O间接电解制合成气，然后进行费托步反应。这项研究发现了三个主要结论。首先，生物基路线在技术经济和碳足迹性能方面明显优于直接和间接路线。其次，电解槽单元是限制直接和间接案例技术经济性能的主要因素，这再次强调了该领域研究人员持续技术进步和降低成本的必要性。最后，间接装置设计，包括两个电解槽和一个费托步骤，对乙烯生产在技术上经济上是不可行的，强调需要进一步研究费托装置设计，以推动替代传统的化石炼油厂。

The concurrent presence of antibiotics and microplastics (MPs) in aquatic environments poses a significant treatment challenge, as conventional approaches largely adhere to a “remove-and-dispose” framework. Herein, we present a sustainable strategy that repurposes iron by-products from Fenton reactions to create functional coordination centers for managing MPs. The newly developed Alginate-Fenton Smart Sequestration (AFSS) system utilizes in-situ generated Fe3+, which is usually considered waste from Fenton process, to cross-link sodium alginate and form a 3D network for effective encapsulation of MPs without the need for additional chemicals. The incorporated reversibility, achieved through biocompatible ascorbic acid, enables the controlled release of MPs, with recovery efficiencies reaching 86% under ambient conditions. The AFSS system demonstrated consistent performance in diverse environmental waters, efficiently degrading antibiotic and maintaining the removal of multiple types of MPs at over 97%. This work establishes a sustainable approach in which residual iron is transformed into a reusable resource for capturing and recovering MPs, thereby advancing water treatment towards circular resource management.

抗生素和微塑料（MPs）在水生环境中的同时存在给治疗带来了重大挑战，因为传统方法在很大程度上坚持“去除和处理”框架。在此，我们提出了一种可持续的策略，重新利用芬顿反应的铁副产品来创建管理MPs的功能协调中心。新开发的藻酸盐-Fenton智能封存（AFSS）系统利用原位生成的Fe3+（通常被认为是Fenton工艺的废物）交联海藻酸钠，形成3D网络，无需额外的化学品即可有效封装MPs。通过生物相容性抗坏血酸实现的掺入可逆性，使MPs可控释放，在环境条件下回收率达到86%。AFSS系统在不同的环境水域中表现出一致的性能，有效地降解抗生素，并将多种MPs的去除率保持在97%以上。这项工作建立了一种可持续的方法，其中残铁转化为可重复使用的资源，用于捕获和回收MPs，从而推动水处理朝着循环资源管理的方向发展。

In the last years great effort was made by the scientific community to investigate the role of phytoplankton in contaminants stress responses and metabolism. However, biotransformation pathways remain underexplored in phytoplankton groups, such as diatoms, that play important ecological roles in natural environment and that are routinely used in biotechnological processes. The present study adopted a multi-omics approach to investigate diclofenac (DCF) physiological effects, transcriptional responses and metabolism in the marine diatom Phaeodactylum tricornutum with the aim of getting an insight on biotransformation pathways. DCF resulted in mild physiological effects on P. tricornutum but gene expression analysis indicated that multiple molecular functions and biological processes were altered during exposure. Transcriptomic analysis suggested increased nutrients and energy requirements possibly associated with the contaminant stress and detoxification metabolism. DCF bioconcentration factor (BCF) was low and varied between 3.9 and 2.7 L Kg-1 depending on the exposure concentration. In total 6 DCF metabolites were detected of which 4’-Hydroxydiclofenac, a metabolite generally associated with Cytochrome P450 (CYP) enzymatic activity. Involvement of CYPs in biotransformation was suggested via indirect evidences. The five additional DCF metabolites detected presented high molecular weight. These metabolites were not previously described in the literature and were hypothesized to be generated via amino acid (or peptides) conjugation. Gene ontology analysis indicated that amino acid and peptide biosynthetic pathways were regulated upon DCF exposure supporting a possible correlation between organic contaminants detoxification responses and amino acid and protein metabolism in this diatom. Our findings provide mechanistic insights into contaminant detoxification and contribute to highlight the diversity of biotransformation pathways in phytoplankton.

近年来，科学界对浮游植物在污染物胁迫反应和代谢中的作用进行了大量的研究。然而，硅藻等浮游植物群的生物转化途径仍未得到充分探索，它们在自然环境中起着重要的生态作用，并经常用于生物技术过程。本研究采用多组学方法研究双氯芬酸（DCF）在海洋硅藻三角藻（Phaeodactylum tricornutum）中的生理效应、转录反应和代谢，旨在了解其生物转化途径。DCF对tricornutum有轻微的生理影响，但基因表达分析表明，DCF对tricornutum的多种分子功能和生物学过程产生了影响。转录组学分析表明，增加的营养和能量需求可能与污染物胁迫和解毒代谢有关。DCF生物浓度因子（BCF）较低，随暴露浓度变化在3.9 ~ 2.7 L Kg-1之间。共检测到6种DCF代谢物，其中4′-羟基双氯芬酸是一种通常与细胞色素P450 （CYP）酶活性相关的代谢物。通过间接证据表明CYPs参与了生物转化。另外5个检测到的DCF代谢物呈现高分子量。这些代谢物以前没有在文献中描述过，假设是通过氨基酸（或肽）偶联产生的。基因本体论分析表明，暴露于DCF后，氨基酸和肽的生物合成途径受到调控，支持有机污染物解毒反应与该硅藻氨基酸和蛋白质代谢之间可能存在相关性。我们的发现为污染物解毒提供了机制见解，并有助于突出浮游植物生物转化途径的多样性。

Excessive sulfate (SO42−) flow into marginal seas through megacity rivers, posing a significant threat to the ecological environment of marginal seas. Tracing and quantifying the source of SO42− are essential for maintaining the health and stability of marine ecosystems. This study reported SO42− concentrations and δ34SSO4 in the Yongding River, a typical megacity river discharging into the sea in northern China. The SO42− concentrations averaged 147 mg·L−1, with δ34SSO4 values ranging from +5.85‰ to +14.99‰. Based on hydrochemical indicators and ion ratios, six potential sources were identified (agriculture, sewage, industry, precipitation, evaporite, and sulfide oxidation). A Monte Carlo inverse model integrating δ34SSO4 and ionic ratios was applied to quantify source contributions. Results show that natural weathering (61%) dominates upstream, while anthropogenic inputs (75%) increase downstream, with sewage and industry sources contributing 41% and 33%, respectively. Sulfide oxidation intensifies near reservoirs, suggesting enhanced oxidation driven by water regulation. Total SO42− flux increased longitudinally, with an estimated annual export of 2.31 × 10−4 Tmol yr−1 to the Bohai Sea. Over 70% of SO42− flux originated from anthropogenic sources, highlighting the critical role of human activities in disrupting sulfur cycling in marginal sea. A hydrology-load-redox (H-L-R) framework was proposed to emphasize the importance of multi-factor coordination in pollution control and land-sea integrated watershed management. This study demonstrates that inverse model holds significant promise for application in complex human-dominated systems, offering a viable approach to strengthen pollutant tracing and risk assessment in marginal marine environments.

过量的硫酸盐（SO42−）通过特大城市河流流入边缘海，对边缘海生态环境构成严重威胁。追踪和量化SO42−的来源对于维持海洋生态系统的健康和稳定至关重要。本文报道了中国北方典型的特大城市入海河流永定河的SO42−浓度和δ34SSO4。SO42−平均浓度147 mg·L−1，δ34SSO4值在+5.85‰~ +14.99‰之间。根据水化学指标和离子比，确定了6个潜在来源（农业、污水、工业、降水、蒸发岩和硫化物氧化）。采用蒙特卡罗反演模型积分δ34SSO4和离子比来量化源贡献。结果表明：自然风化在上游占主导地位（61%），而下游人为输入占75%，其中污水和工业来源分别占41%和33%。硫化物氧化在水库附近加剧，表明由水调节驱动的氧化增强。SO42−总通量纵向增加，估计每年向渤海输出2.31 × 10−4 Tmol yr−1。超过70%的SO42−通量来源于人为来源，突出了人类活动在破坏边缘海硫循环中的关键作用。提出了一个水文负荷-氧化还原（H-L-R）框架，强调多因素协调在污染控制和海陆一体化流域管理中的重要性。该研究表明，逆模型在复杂的人类主导系统中具有重要的应用前景，为加强边缘海洋环境中的污染物追踪和风险评估提供了一种可行的方法。

Seagrasses respond sensitively to both natural and anthropogenic pressures, making them effective indicators for assessing pressure-driven changes in marine ecosystem health. This study developed and validated a novel multimetric Seagrass Ecological Health Index (SEHI) by integrating drone-derived and in situ ecological metrics to assess nearshore seagrass condition in Unguja, Zanzibar. The index combines multiple parameters, including measures of abundance, taxonomic composition, eutrophication, leaf condition, and seascape fragmentation. Relationships between SEHI and key natural pressures—tidal desiccation (TEI) and wave exposure (REID)—as well as anthropogenic pressures such as hotel density, fishing intensity, seaweed farming, sea urchin density, and water quality, were evaluated. SEHI exhibited significant negative correlations with tidal desiccation (r = −0.70, p < 0.05), while wave exposure showed a negative but non-significant trend (r = −0.49), and sea urchin density (r = −0.70, p < 0.05), and responded strongly to phosphate, chlorophyll-a, and seaweed farming intensity. Among the component indicators, epiphytic cover showed the highest sensitivity to human pressures. Based on SEHI classification, five of the nine study sites were in moderate ecological condition, while two were in poor condition. The results demonstrate the robustness of the SEHI framework as an integrative, drone-based and field assessment tool capable of detecting seagrass ecosystem responses to multiple stressors. SEHI provides a scalable approach for monitoring and managing seagrass health in Zanzibar and other tropical, data-limited regions, improving the assessment and communication of seagrass ecological condition to managers and stakeholders involved in coastal and marine conservation.

海草对自然和人为压力都有敏感的反应，这使它们成为评估压力驱动的海洋生态系统健康变化的有效指标。本研究开发并验证了一种新的多度量海草生态健康指数（SEHI），通过整合无人机衍生的和原位生态指标来评估桑给巴尔Unguja近岸海草的状况。该指数结合了多个参数，包括丰度、分类组成、富营养化、叶片状况和海景破碎化。SEHI与关键自然压力-潮汐干燥（TEI）和波浪暴露(REID) -以及人为压力（如酒店密度、捕捞强度、海藻养殖、海胆密度和水质）之间的关系进行了评估。SEHI与潮汐干燥呈显著负相关（r = - 0.70, p < 0.05），波浪暴露与海胆密度呈显著负相关（r = - 0.49, p < 0.05），并对磷酸盐、叶绿素a和海藻养殖强度有强烈响应。各组成指标中，附生盖度对人为压力的敏感性最高。基于SEHI分类，9个研究点中有5个处于中等生态状态，2个处于较差生态状态。结果表明，SEHI框架作为一种综合的、基于无人机的现场评估工具，能够检测海草生态系统对多种应激源的响应，具有鲁棒性。SEHI为监测和管理桑给巴尔和其他数据有限的热带地区的海草健康提供了一种可扩展的方法，改善了海草生态状况的评估，并向参与沿海和海洋保护的管理人员和利益攸关方通报了海草生态状况。

Personal air sampling (PAS) is used to assess worker intake of airborne radioactivity in operations processing minerals containing naturally occurring radionuclides. Subsequent alpha particle counting of the PAS filter may be affected by self-absorption of the alpha particles in the dust matrix or filter, depending on the dust loading on the filter and the size of particles collected. This review investigates the potential for self-absorption on air sampling filters via a literature review and by applying a formula to correct past PAS data from the mineral sand industry. The findings indicate that PAS estimates of intake were consistently under-stated by at least 40% across work categories engaged in the operation and maintenance of mineral sand separation plants. An alpha particle self-absorption greater than 50% was derived when dust loading on the PAS filter exceeded 3 mg·cm^-2. The findings demonstrate that historical PAS data in industries where self-absorption effects are neglected can substantially underestimate worker radionuclide intakes and doses, with important implications for retrospective dose assessment.

个人空气取样（PAS）用于评估工人在加工含有天然放射性核素的矿物的作业中吸入的空气放射性。PAS过滤器的后续α粒子计数可能受到粉尘基质或过滤器中α粒子的自吸收的影响，这取决于过滤器上的粉尘负荷和收集的颗粒大小。本综述通过文献综述和应用公式来纠正矿砂行业过去的PAS数据，研究了空气采样过滤器自吸收的潜力。研究结果表明，在矿砂分离厂的操作和维护工作类别中，PAS对摄入量的估计一直被低估至少40%。当PAS过滤器上的粉尘负荷超过3 mg cm-2时，α粒子的自吸收率大于50%。研究结果表明，忽略自吸收效应的工业的历史PAS数据可能大大低估了工人的放射性核素摄入量和剂量，这对回顾性剂量评估具有重要意义。

Emissions from diesel-powered irrigation pumps (DIPs) in Nepal's agriculture sector contribute to climate change and local air pollution. This study presents the emission estimation using emission factors (EFs) for energy use in DIPs and estimates the contribution of DIPs to the GHGs emission in Nepal using both the bottom-up and top-down approaches. It involves analyzing data on the number of DIPs, the amount of fuel used for irrigation, hours of operations, and efficiency of the pumps. The various EFs for the DIPs were collected from the previous research reports and articles. The activity data for the bottom-up approach was collected from a telephone survey, field sampling, and review of the existing documents. The country-specific EFs for energy use in DIPs developed in Nepal by previous studies using sample measurements were used in this study. The estimated number of DIPs for 2024 is about 51,137 (1.5 to 9 hp; average 5 hp DIPs), operating an average of 192 h per year in Nepal. The DIPs consume 5891 m³ (kL) of fuel per year and emit 14,674 tons of CO₂, 20.9 tons of CH₄, 0.18 tons of N₂O, 71.3 tons of NO_x, 52.2 tons of non-methane volatile organic carbon (NMVOC), 332.0 tons of CO, 54.4 tons of PM_2.5, 40.30 tons of organic carbon (OC), 17.8 tons of black carbon (BC), and 0.6 tons of SO₂ each year. The number of solar-powered irrigation pumps (SIPs) is 3129, which is about 2% of total irrigation pumps in Nepal. Farmers are providing encouraging feedback on the use of SIPs in their small-sized farms. The study shows that the number of electricity-powered pumps has increased rapidly by replacing the DIPs after the mid-2010s due to increased access to the grid electricity. The assessment is expected to support identifying opportunities to reduce emissions through improvements in technology, management practices, and other strategies.

尼泊尔农业部门柴油灌溉泵（DIPs）的排放加剧了气候变化和当地空气污染。本研究提出了利用排放因子（EFs）对dip的能源使用进行排放估算，并使用自下而上和自上而下的方法估算了dip对尼泊尔温室气体排放的贡献。它包括分析dip的数量、用于灌溉的燃料量、运行时间和水泵效率等数据。dip的各种EFs是从以前的研究报告和文章中收集的。自下而上方法的活动数据是从电话调查、实地抽样和对现有文件的审查中收集的。在本研究中使用了尼泊尔以前使用样本测量的研究开发的针对dip能源使用的国别EFs。预计2024年dip数量约为51137台（1.5至9马力；平均dip为5马力），在尼泊尔平均每年运行192小时。DIPs每年消耗5891立方米（kL）燃料，排放14674吨二氧化碳、20.9吨CH4、0.18吨N2O、71.3吨NOx、52.2吨非甲烷挥发性有机碳（NMVOC）、332.0吨CO、54.4吨PM2.5、40.30吨有机碳（OC）、17.8吨黑碳（BC）和0.6吨SO2。太阳能灌溉泵（sip）的数量为3129台，约占尼泊尔灌溉泵总数的2%。农民对在他们的小型农场使用SIPs提供了令人鼓舞的反馈。该研究表明，由于电网供电的增加，2010年代中期以后，电动泵的数量迅速增加，取代了dip。预计该评估将有助于确定通过改进技术、管理实践和其他战略来减少排放的机会。
