Thermal stratification is a significant phenomenon driven by complex interconnected factors that reduce mixing between the top and the bottom layers, impacting oxygen and nutrient dispersion and potentially causing fish mortality. This study has assessed the non-mixing occurrence in river flow using a classification approach, developing a novel hybrid data-driven model from key datasets of the Darling River in Menindee, Australia. The influence of various input variables using the proposed model is investigated, including meteorological drivers, hydrological factors, key data generated by the one-dimensional process-based model named LAKEoneD, and Physics-Informed Neural Networks. The study also considers stratification indices based on the Schmidt stability and empirical river mixing criteria. Supervised machine learning methods were used to classify a given day as mixing or non-mixing conditions. The results showed that the proposed hybrid model integrating Support Vector Machines with key data generated by LAKEoneD outperformed benchmarking models. The study also employed explainable artificial intelligence analysis, suggesting that the minimum air temperature and relative humidity, as the model inputs, played a role in predicting non-mixing river flow conditions. Importantly, the maximum air temperature was another potential input that affected the river flow system, particularly near a fish death event. We conclude that the proposed model can be used as a scientific stratagem for future research in predicting fish and other aquatic organism health related to river flow dynamics, which has implications for environmental authorities guiding better water quality management in river systems.
热分层是一种重要的现象,由复杂的相互关联的因素驱动,减少了顶层和底层之间的混合,影响了氧气和营养物质的分散,并可能导致鱼类死亡。本研究使用分类方法评估了河流流量中的非混合现象,并从澳大利亚Menindee的达令河的关键数据集开发了一种新的混合数据驱动模型。研究了使用该模型的各种输入变量的影响,包括气象驱动因素、水文因素、由一维过程模型LAKEoneD生成的关键数据以及物理信息神经网络。研究还考虑了基于施密特稳定性和经验河流混合准则的分层指标。有监督的机器学习方法用于将给定的一天分类为混合或非混合条件。结果表明,将支持向量机与LAKEoneD生成的关键数据相结合的混合模型优于基准模型。该研究还采用了可解释的人工智能分析,表明最低气温和相对湿度作为模型输入,在预测非混合河流流量条件方面发挥了作用。重要的是,最高气温是影响河流流动系统的另一个潜在输入,特别是在鱼类死亡事件附近。我们的结论是,所提出的模型可以作为未来研究的科学策略,用于预测与河流流量动力学相关的鱼类和其他水生生物的健康,这对环境当局指导更好的河流系统水质管理具有重要意义。

Surface waters that receive discharges from wastewater treatment plants and other sources of pollution are therefore highly susceptible to microbiological contamination. They can be contaminated by a wide variety of viruses, some of which are known to persist in the environment for extended periods. In this study, we assessed the viral contamination of the Seine and Marne rivers in the Paris area by analyzing 42 water samples collected in both winter and summer 2023. Norovirus GI and GII were quantified by RT-qPCR, and a high-throughput PCR array was used for the qualitative detection of 30 viruses, including enteric viruses, respiratory viruses, and indicators of fecal contamination. Noroviruses were detected in 10–82% of the samples tested, depending on the river and season, at concentrations ranging between 5.8 × 101 and 1.1 × 103 genome copies/L. Across the entire sampling campaign, the most prevalent human viruses detected using the PCR array were aichivirus, adenovirus, and bocavirus (74–83%), followed by enterovirus, astrovirus, norovirus, and cosavirus (12–26%). Some other viruses were sporadically detected (sapovirus, hepatitis A and E viruses, OC43, measles virus). The PCR array enables the simultaneous detection of diverse viruses in a single assay, making it a powerful tool for environmental surveillance of multiple pathogens. Its adaptability allows for the detection of a broad range of targets, delivering results within a short timeframe, typically within the same day.
因此,从污水处理厂和其他污染源排放的地表水极易受到微生物污染。它们可能被各种各样的病毒污染,其中一些已知可以在环境中持续很长时间。在这项研究中,我们通过分析2023年冬季和夏季采集的42份水样,评估了巴黎地区塞纳河和马恩河的病毒污染情况。采用RT-qPCR对诺如病毒GI和GII进行定量,并采用高通量PCR阵列对30种病毒进行定性检测,包括肠道病毒、呼吸道病毒和粪便污染指标。根据河流和季节的不同,在10-82%的检测样本中检测到诺如病毒,浓度在5.8 × 101和1.1 × 103基因组拷贝/L之间。在整个采样活动中,使用PCR阵列检测到的最常见的人类病毒是爱奇病毒、腺病毒和bocavavirus(74-83%),其次是肠病毒、astrovirus、诺如病毒和cosavvirus(12-26%)。零星发现其他病毒(萨波病毒、甲型和戊型肝炎病毒、OC43、麻疹病毒)。PCR阵列能够在一次检测中同时检测多种病毒,使其成为多种病原体环境监测的有力工具。它的适应性允许检测范围广泛的目标,在短时间内(通常在同一天内)提供结果。

Coastal wetlands store high amounts of organic carbon (OC) in their sediments, but long-term preservation of this carbon depends on habitat type, sediment depth, and the molecular characteristics of organic matter (OM). This study explores the dynamics of OC deposition and preservation across vertical profiles (0–30 cm) in two adjacent coastal habitats—mudflat, and salt-marsh—within the macrotidal system of the Aiguillon Bay (France). A multi-tracer approach was applied, combining stable isotopes δ13C, C/N ratios, lignin phenols, and fatty acids. Sediment OC content ranged from 13.4 to 23.2 mgC g−1, with the highest concentrations found in the salt-marsh. δ13C and C/N signatures revealed dominant marine source in the mudflat, with a secondary contribution from microphytobenthos, and mixed marine–C₃ plant inputs in the salt-marsh. Fatty acids and lignin compositions supported this partitioning, with surface mudflat layers enriched in labile microbial and algal-derived compounds, whereas deeper salt-marsh sediments retained more resistant, C3 plant-derived signatures resembling those of terrestrial OM source. OM degradation rates were closely linked to source composition and depth. Degradation was concentrated within the top 5 cm of salt-marsh and the top 10 cm of mudflat. Below these depths, biomarker profiles changed minimally, delineating a transition to longer-term preservation. First-order degradation constants were three times higher in mudflat (0.53 yr−1) than in salt-marsh (0.17 yr−1), despite similarly high sedimentation rates (1.8 and 2.2 cm yr−1, respectively). This reflects differences in OM lability, with even minor contributions from microphytobenthos enhancing reactivity in mudflats. Salt-marshes, with their intermediate OM reactivity and high sedimentation rates, emerged as hotspots of carbon accumulation (366 gC m−2 yr −1), while mudflats also contributed substantially to coastal carbon sequestration (239 gC m−2 yr −1). These results highlight the value of depth-resolved, biomarker-based approaches to identify habitat-specific degradation dynamics; ultimately better understanding carbon accumulation in coastal ecosystems.
滨海湿地沉积物中储存了大量的有机碳(OC),但这种碳的长期保存取决于生境类型、沉积物深度和有机质(OM)的分子特征。本研究探讨了法国Aiguillon湾大潮系统中两个相邻的沿海栖息地-泥滩和盐沼-在垂直剖面(0-30 cm)上的OC沉积和保存动态。采用多示踪法,结合稳定同位素δ13C、C/N比、木质素酚和脂肪酸。沉积物OC含量在13.4 ~ 23.2 mg - g-1之间,盐沼中OC含量最高。δ13C和C/N特征表明泥滩以海相为主,微底栖植物次之,盐沼以海相-C₃植物混合输入为主。脂肪酸和木质素组成支持这种划分,表面泥滩层富含不稳定的微生物和藻类衍生的化合物,而更深的盐沼沉积物保留了更抗性的C3植物衍生的特征,类似于陆地OM源。有机质降解率与源成分和深度密切相关。退化主要集中在盐沼顶部5 cm和泥滩顶部10 cm。在这些深度以下,生物标记谱变化最小,描绘了向长期保存的过渡。泥滩的一级降解常数(0.53年-1年)是盐沼的三倍(0.17年-1年),尽管沉积速率同样高(分别为1.8厘米和2.2厘米-1年)。这反映了有机质稳定性的差异,即使微小底栖植物的贡献很小,也会增强泥滩的反应性。盐沼具有中等有机质反应性和高沉积速率,成为碳积累的热点(366 gC m-2 yr -1),而泥滩也对沿海碳封存做出了重大贡献(239 gC m-2 yr -1)。这些结果突出了深度分辨、基于生物标志物的方法在识别栖息地特定退化动态方面的价值;最终更好地了解沿海生态系统中的碳积累。

Surgical procedures are resource-intensive and require sophisticated devices and equipment, stringent sterilization and disinfection protocols, considerable amounts of consumables and advanced operative technologies. These features collectively result in the generation of medical waste and healthcare-related emissions. While minimally invasive surgery offers patient-centred benefits such as reduced postoperative length of stay, it presents circularity challenges due to its reliance on single-use devices, as well as regulatory constraints on medical waste management. The growing demand for minimally invasive surgery has led to an increased use of devices like single-use surgical staplers. The most common end-of-life (EOL) treatment for single-use surgical staplers is incineration, due to safety concerns and regulatory restrictions. Therefore, evaluating the environmental impact of alternative waste management options (such as recycling) for these devices has become more crucial. This study evaluates the environmental impacts of a single-use, battery-powered surgical stapler. Hotspots are identified and the benefits of shifting from incineration with energy recovery to recycling after disinfection and sterilization are assessed. A life cycle assessment was conducted using the Environmental Footprint method, covering the entire life cycle. Four midpoint impact categories, climate change, freshwater ecotoxicity, fossil resource use, and mineral and metal resource use, along with a single score were analysed. The results show that the supply and manufacturing of components dominate the four impact categories and the single score, largely due to the supply of electronic components. EOL burdens are higher for incineration than for recycling, except for fossil resource use. Disinfection and sterilization are the main contributors to the recycling burden. For recycling to be more viable in terms of environmental sustainability, strategies should focus on device design to increase recyclability, improve recycling technologies, and make sterilization more efficient.
外科手术是资源密集型的,需要精密的装置和设备、严格的灭菌和消毒方案、大量的消耗品和先进的手术技术。这些特征共同导致医疗废物和医疗保健相关排放物的产生。虽然微创手术提供了以患者为中心的好处,例如缩短了术后住院时间,但由于依赖一次性设备以及对医疗废物管理的监管限制,它带来了循环挑战。对微创手术日益增长的需求导致了诸如一次性手术订书机等设备的使用增加。出于安全考虑和监管限制,一次性手术订书机最常见的报废(EOL)处理是焚烧。因此,评估替代废物管理方案(如回收利用)对这些设备的环境影响变得更加重要。本研究评估了一次性电池供电手术订书机对环境的影响。确定了热点,并评估了从焚烧和能源回收转向消毒和灭菌后再循环的好处。采用环境足迹法进行了覆盖整个生命周期的生命周期评估。四个中点影响类别,气候变化,淡水生态毒性,化石资源利用,矿物和金属资源利用,以及一个单一的分数进行了分析。结果表明,元器件的供应和制造在四个影响类别和单一得分中占主导地位,这在很大程度上是由于电子元器件的供应。焚烧的EOL负担高于回收,但化石资源的使用除外。消毒和灭菌是造成回收负担的主要原因。为了使回收在环境可持续性方面更具可行性,策略应侧重于设备设计,以提高可回收性,改进回收技术,并提高灭菌效率。

Introduction

Whether early-life exposure to persistent organic pollutants (POPs) associates with adult cognitive function is unknown. We examined the association of childhood serum POPs levels with cognitive function in midlife.

Methods

This was a prospective cohort study of 1304 children aged 3–18 years. Childhood serum levels of 18 POPs including p,p′-dichlorodiphenyltrichloroethane (p,p′-DDT), p,p′-dichlorodiphenyldichloroethylene (pp′-DDE), pentachlorobenzene (PeCB), hexachlorobenzene (HCB), hexachlorocyclohexanes (HCHs), polychlorinated biphenyls (PCBs), trans-nonachlor were measured in childhood and early adulthoood. In mid-adulthood, cognitive function was measured using a computerized test battery (CANTAB) including tests for 1) memory and learning, 2) working memory, 3) reaction time, and 4) information processing. We assessed the overall association of the 18 POPs with cognitive function (normalized with mean 0 and standard deviation 1) by deriving a POP mixture index using weighted quantile sum (WQS) regression.

Results

For every unit-increase in the derived POP index (range 0–3, SD = 0.7), 0.129 (95% CI: −0.244, −0.014) SD-units lower memory and learning in midlife was observed when adjusting for covariates and adult POP index. This association was stable as shown by repeated holdout validation (β = −0.086, 95% confidence interval: −0.160 to −0.011), corresponding to 1.7 years additional aging on memory and learning. The POP mixture index was predominated by HCB (23%), p,p′-DDT (21%), PCB99 (10%), and p,p′-DDE (10%).

Conclusions

Childhood exposure to a high level of multiple POPs, such as HCB, p,p′-DDT and PCB99, was associated with poorer memory and learning in midlife, independent of adult exposure to those POPs.
早期接触持久性有机污染物(POPs)是否与成人认知功能相关尚不清楚。我们研究了儿童血清POPs水平与中年认知功能的关系。方法:对1304名3-18岁儿童进行前瞻性队列研究。测定了儿童和成年早期血清中p,p'-二氯二苯三氯乙烷(p,p'-DDT)、p,p'-二氯二苯二氯乙烯(pp'-DDE)、五氯苯(PeCB)、六氯苯(HCB)、六氯环己烷(HCHs)、多氯联苯(PCBs)、反式壬氯胺等18种持久性有机污染物的含量。在成年中期,使用计算机化测试电池(CANTAB)测量认知功能,包括1)记忆和学习测试,2)工作记忆测试,3)反应时间测试和4)信息处理测试。我们通过加权分位数和(WQS)回归得出POP混合指数,评估了18种POP与认知功能的总体关联(均值为0,标准差为1)。结果:当调整协变量和成人POP指数时,导出的POP指数每增加一个单位(范围0-3,SD = 0.7), 0.129 (95% CI: -0.244, -0.014) SD-单位的中年记忆和学习下降。经反复验证,这种关联是稳定的(β = -0.086, 95%置信区间:-0.160至-0.011),对应于1.7年的记忆和学习额外老化。POP混合指数以HCB(23%)、p,p′-DDT(21%)、PCB99(10%)和p,p′-DDE(10%)为主。结论:儿童期暴露于高水平的多种持久性有机污染物(如HCB、p、p'-DDT和PCB99)与中年时较差的记忆力和学习能力有关,与成年期暴露于这些持久性有机污染物无关。

This study assessed the effectiveness of constructed floating wetlands (CFWs) amended with biochar and bioactive biochar hanging columns in removing three pharmaceuticals and personal care products (PPCPs: metronidazole (MNZ), naproxen (NAP), and methylparaben (MeP)) along with residual organics and nutrients. The impact of biochar amendments on the removal of organics, nutrients, and targeted PPCPs was evaluated under both batch and continuous operations. In batch-scale experiments, CFWs incorporating bioactive/biochar columns and plants achieved over 80% removal of organics and 70% reduction in nutrients, driven primarily by the synergistic actions of plants, microbes, and biochar. PPCP removal rates were notably high, exceeding 80–90% in systems with plants and hanging biochar columns. In continuous mode, reductions of PPCPs and organics exceeded 75% at a 6-day hydraulic retention time (HRT), with performance declining at shorter HRTs. CFWs combining biochar columns and plants reduced ecotoxicological risk to aquatic life by up to 90%, outperforming units with only biochar or plants. Mass balance analysis indicated that 35–71% of PPCPs were removed through a synergistic action of plants, microbes and biochar in the CFWs. Pollutant reduction in biochar-amended CFWs occurred through multiple mechanisms, including adsorption onto biochar, photodegradation, microbial degradation, and plant uptake. Oxidative stress in plants, reactive oxygen species (ROS) accumulation, was plants due to PPCPs exposure, however amended biochar column can reduce the PPCP-induced phytotoxicity. Microbial analyses further revealed enrichment of biodegradation-associated genera (Pseudomonas and Nitrospira). These results reveal the synergistic role of biochar, plants, and microbial communities in enhancing pollutant attenuation in CFWs.
本研究评估了生物炭和生物活性生物炭悬浮柱改性人工漂浮湿地(CFWs)去除三种药物和个人护理用品(ppcp:甲硝唑(MNZ)、萘普生(NAP)和对羟基苯甲酸甲酯(MeP))及其残留有机物和营养物质的效果。在间歇和连续操作下,评估了生物炭改性对有机物、营养物质和目标PPCPs去除的影响。在批量规模的实验中,结合生物活性/生物炭柱和植物的CFWs实现了超过80%的有机物去除和70%的营养物质减少,主要是由植物、微生物和生物炭的协同作用驱动的。PPCP去除率非常高,在植物和悬挂生物炭柱的系统中,去除率超过80-90%。在连续模式下,在6天的水力滞留时间(HRT)下,PPCPs和有机物的减少量超过75%,而在更短的HRT下,性能下降。结合生物炭柱和植物的cfw可将水生生物的生态毒理学风险降低高达90%,优于仅使用生物炭或植物的装置。质量平衡分析表明,35-71%的PPCPs通过植物、微生物和生物炭的协同作用被去除。生物炭改性的CFWs通过多种机制实现污染物的减少,包括吸附在生物炭上、光降解、微生物降解和植物吸收。ppcp暴露导致植物氧化应激,活性氧(ROS)积累,而改性生物炭柱可以降低ppcp诱导的植物毒性。微生物分析进一步揭示了生物降解相关属(假单胞菌和硝化螺旋菌)的富集。这些结果揭示了生物炭、植物和微生物群落对CFWs中污染物衰减的协同作用。

We investigated coarse (PM10) and fine (PM2.5) particulate matter–bound carbon nanoparticles, characterizing their surface chemistry, morphology, topography, and composition to gain insights into their environmental toxicological implications. Comprehensive preclinical toxicological studies including in vitro cytotoxicity, oxidative potential and in vivo assessments were carried out to evaluate health risks associated with these ambient nanoparticles. This study revealed that PM10 and PM2.5 samples disintegrate into nanoparticles (<100 nm) in water extract during ultrasonication, indicating that PM consists of aggregated carbon nanostructures and metallic nanoparticles. These nanoparticulates can be internalized by cells and consequently reduce viability of human epithelial kidney cells (HEK-293) upto 64.95 ± 0.33% and 45.14 ± 2.8%, respectively, at 500 μg/mL in a dose-dependent manner relative to untreated controls. It also demonstrates that particulate-bound nanoparticles elicit significant toxic effects on macrophage cell line (RAW 264.7) derived from mice, primarily through induction of intracellular reactive oxygen species (ROS) surge. In vivo exposure to PM induces significant pulmonary toxicity, as evident from presence of inflammatory cell infiltration in BALF and distinct histopathological changes including vasculitis and vascular congestion, low grade focal hemorrhage, epithelial damage and alveolar cell hyperplasia, collectively underscoring the harmful consequences of particulate inhalation and this evaluation pave the way for awareness and targeted prevention strategies in the future.

Agriculture practices induce profound changes in soil biological properties and soil functioning. However, we still lack an understanding of how soil fungal biodiversity responds to various practices. Metagenomic tools were used to investigate soil fungal communities and inferred ecological functions based on functional guild classification in response to the effect of climate region and land management. This study assessed how seasonal timing and long-term land management affect soil fungal communities, with the aim of exploring their potential as candidate indicators of soil biological status. We collected soil samples across two regions of Israel (Mediterranean north and semi-arid south), three land-use types—orchard (OR), field crops (FC), and non-cultivated control (CO)—and two seasons—autumn and spring. Abiotic parameters varied significantly by season, region, and depth, underscoring the importance of considering sampling time in soil assessment. Fungal community composition showed marked differences between land uses, suggesting sensitivity to long-term management. CO and OR soils consistently exhibited higher fungal diversity and network connectivity, while FC soils had lower richness and unique taxa. A stable core community of 10 genera was found across treatments. Functional guilds were dominated by saprotrophs, though specific taxa and guild contributions varied by management type and season. Overall, our results emphasize the importance of sampling timing and land-use history in shaping fungal communities and support the potential of fungal-based indicators for assessing soil status across agricultural systems.
农业实践引起土壤生物特性和土壤功能的深刻变化。然而,我们仍然缺乏对土壤真菌生物多样性如何响应各种实践的理解。利用宏基因组分析工具对土壤真菌群落进行了研究,并基于功能行会分类推断了土壤真菌在气候区域和土地管理影响下的生态功能。本研究评估了季节时序和长期土地管理对土壤真菌群落的影响,旨在探索其作为土壤生物状况候选指标的潜力。我们收集了以色列两个地区(地中海北部和半干旱南部)的土壤样本,三种土地利用类型-果园(OR),大田作物(FC)和非栽培对照(CO),以及两个季节-秋季和春季。非生物参数随季节、区域和深度的变化而显著变化,强调了在土壤评估中考虑采样时间的重要性。真菌群落组成在不同土地利用方式下存在显著差异,表明对长期管理的敏感性。CO和OR土壤具有较高的真菌多样性和网络连通性,而FC土壤具有较低的丰富度和独特的分类群。在不同处理间发现了一个稳定的10个属的核心群落。功能行会以腐养生物为主,但具体的类群和行会的贡献因管理类型和季节而异。总体而言,我们的研究结果强调了采样时间和土地利用历史在塑造真菌群落中的重要性,并支持基于真菌的指标在评估农业系统土壤状况方面的潜力。
