Given its extensive global usage and environmental persistence conferred by the stable triazine ring structure, the frequent detection of atrazine (ATZ) in the environment poses ecological and health risks. Spent mushroom substrate (SMS), as a widely available and low-cost agricultural waste, and its lignocellulosic composition and inherent porosity are conducive to generating highly aromatic and porous biochar structures for adsorbing ATZ. This study pioneeringly prepared biochar (BC) and acid-treated BC derived from SMSs of Pleurotus ostreatus, Oudemansiella apalosarca, and Lentinula edodes) via pyrolysis at 800 °C. Comprehensive characterization confirmed that the physicochemical properties of BC were significantly influenced by feedstock origin and acid treatment. Acid treatment improved specific surface area, porosity, and aromaticity, and alongside reduced hydrophilic ash content. Batch experiments indicated that acid-treated BC improved ATZ adsorption efficiency with removal rates increasing by 3.5–5.6 times, following the order of APBC (98.2 %) > AOBC (38.4 %) > ALBC (27.1 %). Adsorption kinetics and isotherms indicated heterogeneous surface interactions and multi-mechanism involvement. The elevated logK_OC values of acid-treated BC reflected stronger affinity for ATZ on organic carbon-enriched sites. Mechanistic analysis quantified four dominant pathways with distinct contribution ranges of pore filling (2.2–42.4 %), hydrophobic partitioning (2.2–47.2 %), π–π electron donor-acceptor interactions (15.6–49.8 %), and hydrogen bonding (0.9–35.0 %). Thermodynamic studies revealed spontaneous, endothermic, and entropy-driven adsorption processes, and adsorption capacity of ATZ was favored under acidic and high-temperature conditions. These findings not only offer a solution for agricultural byproducts SMSs reuse into high-efficiency adsorbents through pyrolysis and acid modification but also establish a method to mitigate pesticide contamination in aqueous systems.

鉴于阿特拉津在全球的广泛使用以及稳定的三嗪环结构所赋予的环境持久性，在环境中频繁检测到阿特拉津（ATZ）会带来生态和健康风险。蘑菇废底物（SMS）作为一种广泛利用的低成本农业废弃物，其木质纤维素成分和固有的孔隙度有利于生成高芳香和多孔的生物炭结构，以吸附ATZ。本研究率先从平菇（Pleurotus ostreatus）、白蜡菇（Oudemansiella apalosarca）和香菇（Lentinula edodes）的sms中提取生物炭（BC）和酸处理后的BC。综合表征表明，原料来源和酸处理对BC的理化性质有显著影响。酸处理改善了比表面积、孔隙度和芳香性，同时降低了亲水性灰分含量。批量实验表明，酸处理后的BC对ATZ的吸附效率提高了3.5 ~ 5.6倍，去除率依次为APBC（98.2%）、AOBC（38.4%）、AOBC（27.1%）。吸附动力学和等温线显示了非均匀的表面相互作用和多机制参与。酸处理BC的logKOC值升高反映了ATZ对有机碳富集位点的亲和力增强。机制分析量化了孔隙填充（2.2 - 42.4%）、疏水分配（2.2 - 47.2%）、π -π电子供体-受体相互作用（15.6 - 49.8%）和氢键（0.9 - 35.0%）四个主要途径。热力学研究揭示了ATZ的自发吸附、吸热吸附和熵驱动吸附过程，在酸性和高温条件下，ATZ的吸附能力更强。这些发现不仅为农业副产品SMSs通过热解和酸改性转化为高效吸附剂提供了解决方案，而且为减轻水系统中的农药污染提供了一种方法。

The persistence of Pb²⁺ in aquatic systems necessitates efficient and recyclable adsorbents for sustainable remediation. In this work, pure LaFeO₃ (LFO) and Co-doped LaFeO₃ (LaFe₀.₉Co₀.₁O₃ and LaFe₀.₈Co₀.₂O₃) nanoparticles were synthesized via a sol-gel auto-combustion route and evaluated for lead removal from water. Structural analyses confirmed a single-phase orthorhombic perovskite structure with systematic reductions in lattice parameters and crystallite size upon cobalt substitution. Charge neutrality was maintained through the formation of tetravalent Fe⁴⁺ species, while XPS revealed the coexistence of oxygen vacancies and mixed Fe³⁺/Fe⁴⁺ valence states that collectively promote enhanced adsorption behavior. Optical measurements revealed a tunable bandgap, decreasing from 2.23 eV to 1.82 eV with increasing Co content, a trend further corroborated by DFT analysis. LaFe₀.₈Co₀.₂O₃ exhibited the highest Pb²⁺ adsorption efficiency, removing 2.49 ppm of Pb²⁺ from a 3.88 ppm solution, corresponding to a 64.2 % removal. The adsorption followed pseudo-second-order kinetics and the Freundlich isotherm. Enhanced magnetic properties with increasing Co content facilitate magnetic separation and indicate potential for future reusability. These results highlight that Co doping simultaneously improves adsorption performance and magnetic response, establishing Co-doped LFO nanoparticles as a promising perovskite-based platform for Pb²⁺ removal in water purification applications.

Pb 2 +在水生系统中的持久性需要高效和可回收的吸附剂来进行可持续的修复。在这项工作中，纯LaFeO₃（LFO）和共掺杂LaFeO₃(LaFe₀。₁O₃和LaFe₀₈Co₀。采用溶胶-凝胶自燃烧法合成了2 O₃纳米粒子，并对其去除水中铅的效果进行了评价。结构分析证实了一种单相正交钙钛矿结构，在钴取代后，晶格参数和晶粒尺寸都有系统的减小。通过形成四价Fe⁴⁺保持了电荷中性，而XPS揭示了氧空位和混合Fe³+ /Fe⁴⁺价态的共存，这些价态共同促进了吸附行为的增强。光学测量表明，随着Co含量的增加，带隙从2.23 eV减小到1.82 eV，这一趋势得到了DFT分析的进一步证实。劳工局代理大律师拉夫₀。指出₈₀。2 O₃的Pb 2⁺的吸附效率最高，从3.88 ppm的溶液中去除了2.49 ppm的Pb 2⁺，去除率为64.2%。吸附遵循拟二级动力学和Freundlich等温线。随着Co含量的增加，磁性能的增强有助于磁分离，并表明未来可重复使用的潜力。这些结果强调了Co掺杂同时提高了吸附性能和磁响应，建立了Co掺杂LFO纳米颗粒作为一种有前途的钙钛矿基平台，用于水净化应用中Pb 2 +的去除。

Oxygenated Polycyclic Aromatic Compounds (O-PACs) have been detected in soils and groundwater at sites polluted by Polycyclic Aromatic Hydrocarbons (PAHs), raising concerns due to their higher toxicity and potential to form larger pollution plumes. This study investigated O-PAC behavior in soils and identified the underlying mechanisms and influencing parameters. Breakthrough curves were generated to characterize the sorption of a PAH (fluorene – FLU) and an O-PAC (9H-fluorenone – FLUone), using soil columns at the laboratory scale. Desorption curves were also measured. These curves were modeled using the HYDRUS-1D model. The effects of pollutant concentration and influent flow rate were studied. Results indicated that FLUone exhibited a lower affinity for the soil matrix compared to FLU. This suggested that upon release from pollution sources in soils, O-PACs could migrate more rapidly to groundwater than PAHs, potentially forming larger pollution plumes. Additionally, the results confirmed that FLUone sorption onto soil was primarily controlled by surface mechanisms, with intra-aggregate diffusion playing a minor role. This finding was supported by the dependency of FLUone sorption on inlet solution concentration and corroborated by the modeling, indicating a lower sensitivity of the number of instantaneous sorption sites to a flow rate change. Nevertheless, results showed that lower O-PAC concentrations were associated with a higher proportion of intra-particle diffusion processes. FLUone sorption was more reversible than FLU sorption, indicating that O-PACs could be preferentially released from polluted soils. All these results highlighted the need to consider O-PACs alongside PAHs in polluted site characterization and monitoring.

在多环芳烃（PAHs）污染的土壤和地下水中检测到氧合多环芳烃（O-PACs），由于其较高的毒性和可能形成更大的污染柱，引起了人们的关注。本研究研究了O-PAC在土壤中的行为，并确定了其潜在机制和影响参数。利用实验室规模的土壤柱，生成突破曲线来表征PAH（芴- FLU）和O-PAC （9h -芴酮- FLUone）的吸附。同时测定了解吸曲线。这些曲线采用HYDRUS-1D模型建模。研究了污染物浓度和进水流量的影响。结果表明，与FLU相比，FLUone对土壤基质的亲和力较低。这表明，在土壤污染源释放后，o - pac比PAHs更快地迁移到地下水中，可能形成更大的污染羽流。此外，研究结果还证实了FLUone在土壤上的吸附主要受表面机制控制，团聚体内扩散起次要作用。这一发现得到了FLUone吸附对进口溶液浓度的依赖性的支持，并得到了模型的证实，表明瞬时吸附位点的数量对流速变化的敏感性较低。然而，结果表明，较低的O-PAC浓度与较高比例的颗粒内扩散过程相关。与FLU吸附相比，FLUone吸附的可逆性更强，表明O-PACs可以优先从污染土壤中释放。所有这些结果都突出了在污染场地的表征和监测中考虑o - pac和多环芳烃的必要性。

This study examines the oxidative potential of fine particulate matter (PM_2.5) in a metropolitan area by analyzing particle number size distribution and chemical composition across diurnal patterns. The oxidative potential was quantified using the dithiothreitol assay, normalized to 9,10-phenanthrenequinone (QDTT-OP). The QDTT-OP was apportioned to four sources: waste PET and wood burning (141 nm, 33 %), vehicle emissions (46 nm, 32 %), long-range transport (>429 nm, 22 %), and in-situ condensation process (15 nm, 13 %). Waste burning, characterized by the presence of terephthalic acid and levoglucosan accounted for the highest QDTT-OP during nighttime. Vehicle emissions were aligned with rush-hour peaks, while long-range transport was associated with elevated levels of secondary inorganic aerosols during regional intrusion events. In-situ condensation process, characterized by ultrafine particles, occurred during the early morning hours. The integration of positive matrix factorization with particle sizing and tracer analysis facilitated detailed identification of QDTT-OP sources. These results highlight the importance of addressing both regional combustion-related emissions and transported aerosols in assessments of PM_2.5 oxidative potential and associated public health impacts.

Membrane technology has been embraced as the best technology for process separation and purification by virtue of its economic and environmental advantages. The performance of membrane technology is assessed by its selectivity and hydraulic output, which are challenged by membrane fouling. Membrane fouling encourages hydraulic resistance and retarded the selectivity of the membrane. Therefore, membrane fouling is the prime downside of membrane technology and it can be modulated by developing the membrane surface chemistry and/or the filtration system hydrodynamics. Membrane surface chemistry and filtration system hydrodynamics development for membrane fouling control have been intensively explored and many concepts are emerging day by day. Therefore, its paramount to review the performance of the emerging concepts and develop a roadmap for exploration of new concepts. This manuscript reviews the recent advances in membrane surface chemistry and filtration system hydrodynamics development for membrane fouling control in liquid filtration. The focus is mainly on the mechanisms and limitations of membrane surface chemistry and filtration system hydrodynamics development for membrane fouling mitigation. Moreover, the manuscript also outlined the future perspectives of membrane surface chemistry and filtration system hydrodynamics development for optimum membrane fouling control.

Fate modeling and spatial health risk assessment of urban polycyclic aromatic hydrocarbons using a kilometer-resolution multimedia model 基于公里分辨率多媒体模型的城市多环芳烃命运建模与空间健康风险评价

Polycyclic aromatic hydrocarbons (PAHs), as highly carcinogenic persistent pollutants, pose challenges for assessing urban multimedia distribution and exposure risks due to limited spatial resolution of conventional models. Traditional fugacity models, constrained by homogeneity assumptions, fail to capture environmental heterogeneity in high-density cities. This study developed a kilometer-resolution steady-state multimedia model to characterize the fate and health risks of PAHs in Nanjing, with model predictions validated against measured concentrations across 13 environmental compartments. The results reveal a distinct concentration hierarchy: organic film > sediment > soil > vegetation > water > atmosphere. Organic film (57.2–68.7 %) and water (28.5–37.5 %) are the dominant contributors to incremental lifetime cancer risk (ILCR), highlighting their priority for risk management. Health risks exhibit significant age differentiation: children are more sensitive to atmospheric PAH exposure, adolescents are predominantly affected by soil, vegetation, and organic film, and overall ILCR follows the gradient Adults > Youths > Children (ranging from 1.22 × 10^–9 to 4.00 × 10^–5), driven by age-dependent behavioral and physiological differences. Among individual PAHs, BaP (54.12 %-56.10 %) and DahA (20.47 %-23.39 %) dominate cumulative toxicity risks. Assessment of eight toxicity endpoints identifies respiratory toxicity, carcinogenicity, estrogen receptor toxicity, aryl hydrocarbon receptor toxicity, and antioxidant response disruption as core health impacts, primarily driven by high-molecular-weight PAHs. This high-resolution modeling framework enables precise identification of urban PAH pollution hotspots and age-specific exposure risks, providing critical scientific support for targeted pollution control and public health protection in high-density cities.

多环芳烃（PAHs）是一种高度致癌的持久性污染物，由于传统模型的空间分辨率有限，给城市多媒体分布和暴露风险评估带来了挑战。传统的逸度模型受到同质性假设的约束，无法捕捉高密度城市的环境异质性。本研究开发了一种千米分辨率的稳态多媒体模型来表征南京多环芳烃的命运和健康风险，并根据13个环境隔间的测量浓度对模型预测进行了验证。结果显示了一个明显的浓度层次：有机膜>；沉积物>；土壤>；植被>；水>；大气。有机膜（57.2 - 68.7%）和水（28.5 - 37.5%）是增加终生癌症风险（ILCR）的主要因素，突出了它们在风险管理中的优先地位。健康风险表现出明显的年龄差异：儿童对大气多环芳烃暴露更敏感，青少年主要受土壤、植被和有机膜的影响，总体ILCR遵循成人>；青年>；儿童的梯度（范围从1.22 × 10-9到4.00 × 10-5），受年龄依赖性行为和生理差异的驱动。PAHs中，BaP（54.12% ~ 56.10%）和DahA（20.47% ~ 23.39%）的累积毒性风险最大。对八个毒性终点的评估确定了呼吸毒性、致癌性、雌激素受体毒性、芳烃受体毒性和抗氧化反应破坏是主要由高分子量多环芳烃驱动的核心健康影响。这种高分辨率的建模框架能够精确识别城市多环芳烃污染热点和特定年龄的暴露风险，为高密度城市的定向污染控制和公共卫生保护提供关键的科学支持。

Heavy metal toxicity seriously threatens the health of people, plants, and the food chain in developing countries. A review of the Science Direct, PubMed, Web of Science, Google Scholar, Springer, and Scopus databases was performed to assess the sources, exposure, toxicity mechanism, human health aspects, and detection techniques related to Cd, Cr, Mn, Ni, and Cu between 2019 and 2024. Moreover, AI-powered models particularly Random Forest (RF) for predictive analysis and Convolutional Neural Networks (CNNs) for spatial mapping to highlight significant contamination hotspot, were examined for their efficiency and reliability to identify and detect the distribution of heavy metals. The environment is frequently polluted with heavy metals as a result of improper home waste disposal, industrial and agricultural operations, and overuse of pesticides and fertilizers in developing countries. China contributed the most to heavy metals research, followed by the United States. The accumulation and exposure to heavy metals lead to potential outcomes in humans. Long-term exposure to certain heavy metals is significantly associated with increased risk of developing various cancer types such as prostate, lung, throat, breast, blood, and brain cancers. The current study found in light of the existing identification and detection techniques' pros and cons, X-ray fluorescence spectroscopy (XRF) is a promising technique to quantify and detect heavy metals owing to its rapid, on-site, and non-destructive screening method.

Based on gaps found in the literature, the current review suggests that integrating AI algorithms with nanotechnology and new biosensor platforms to accomplish high-precision, real-time environmental monitoring is an important future direction. To protect the community, longitudinal health studies, biomonitoring, and the use of green remediation technologies should be encouraged.

在发展中国家，重金属毒性严重威胁着人、植物和食物链的健康。对Science Direct、PubMed、Web of Science、谷歌Scholar、施普林格和Scopus数据库进行了回顾，以评估2019年至2024年间与Cd、Cr、Mn、Ni和Cu相关的来源、暴露、毒性机制、人类健康方面和检测技术。此外，人工智能驱动的模型，特别是用于预测分析的随机森林（RF）和用于空间映射的卷积神经网络（cnn），以突出重要的污染热点，研究了它们识别和检测重金属分布的效率和可靠性。在发展中国家，由于家庭废物处理不当、工业和农业作业以及过度使用杀虫剂和化肥，环境经常受到重金属污染。中国对重金属研究的贡献最大，其次是美国。重金属的积累和暴露会对人类造成潜在的后果。长期接触某些重金属会显著增加患各种癌症的风险，如前列腺癌、肺癌、喉癌、乳腺癌、血癌和脑癌。目前的研究发现，鉴于现有鉴定和检测技术的优缺点，x射线荧光光谱（XRF）以其快速、现场、无损的筛选方法，是一种很有前途的重金属定量和检测技术。基于文献中发现的空白，目前的综述表明，将人工智能算法与纳米技术和新的生物传感器平台相结合，以实现高精度、实时的环境监测是一个重要的未来方向。为保护社区，应鼓励进行纵向健康研究、生物监测和使用绿色修复技术。

To evaluate the biocompatibility of various nanomaterials in aquatic invertebrates and their biocompatibility profiles relevant to gene delivery applications, this study systematically compares the effects of four representative nanocarriers—mesoporous silica nanoparticles (MSN), chitosan derivatives (CTMT), PEI–PEG copolymers (TNP), and lipid nanoparticles (LNP)—across four developmental stages of Penaeus monodon (Nauplius, Zoea, Mysis, and Post-larva). Acute effects on larval survival and development, tissue injury, and molecular responses were comprehensively assessed through mortality rates, morphological abnormalities, and multichannel fluorescence staining. Among the tested materials, MSN induced the most pronounced cellular damage and lethality at all stages, whereas TNP and LNP caused lower mortality, fewer larval malformations, and weaker cellular stress responses, indicating superior biocompatibility. Transcriptomic analysis revealed that MSN exposure triggered extensive differential gene expression associated with energy metabolism, protease regulation, and immune response, displaying distinct stage-specific patterns. Core gene network analysis identified RHOA, CASP1, and Spn88Ea as key mediators potentially involved in MSN-induced apoptosis and stress responses. Collectively, the findings indicate that TNP and LNP exhibit higher biocompatibility and may represent safer candidates for future nucleic-acid delivery studies, whereas MSN, despite its structural advantages, requires stringent control of dosage and exposure duration prior to application. This study provides essential data and theoretical support for the selection and safety evaluation of nano-delivery systems in aquatic animals.

为了评估各种纳米材料在水生无脊椎动物中的生物相容性及其与基因传递应用相关的生物相容性特征，本研究系统地比较了四种具有代表性的纳米载体——介孔二氧化硅纳米颗粒（MSN）、壳聚糖衍生物（CTMT）、PEI-PEG共聚物（TNP）和脂质纳米颗粒（LNP）在单对虾（Nauplius、Zoea、Mysis和幼虫后）四个发育阶段的影响。通过死亡率、形态学异常和多通道荧光染色综合评估对幼虫存活和发育、组织损伤和分子反应的急性影响。在所测试的材料中，MSN在所有阶段诱导的细胞损伤和致死性最为明显，而TNP和LNP的死亡率较低，幼虫畸形较少，细胞应激反应较弱，表明其具有较好的生物相容性。转录组学分析显示，MSN暴露引发了与能量代谢、蛋白酶调节和免疫反应相关的广泛差异基因表达，显示出不同的阶段特异性模式。核心基因网络分析发现，RHOA、CASP1和Spn88Ea是可能参与msn诱导的细胞凋亡和应激反应的关键介质。总的来说，研究结果表明TNP和LNP具有更高的生物相容性，可能是未来核酸递送研究中更安全的候选物，而MSN尽管具有结构优势，但在应用前需要严格控制剂量和暴露时间。本研究为水生动物纳米给药系统的选择和安全性评价提供了必要的数据和理论支持。

The burgeoning field of smart textiles for pollutant gas sensing and capture is poised to revolutionize personal safety and environmental monitoring, offering a crucial alternative to bulky, stationary systems by providing personalized, real-time data. This comprehensive review synthesizes the latest advancements across the entire technology spectrum, starting with fundamental sensing principles. We analyze the mechanisms, materials, and recent breakthroughs in chemiresistive sensing (leveraging materials like graphene and carbon nanotubes for high-sensitivity electronic response) and optical/colorimetric sensing (providing visible, quantifiable feedback). Furthermore, we detail the active pollutant removal capabilities, encompassing adsorption such as Metal-Organic Frameworks (MOFs) for high-capacity capture), absorption, and catalytic conversion (for proactive pollutant neutralization). The review highlights the role of innovative nanomaterials and the scalability of key fabrication methods, including inkjet, screen printing, electrospinning, and In-situ growth. These technologies underpin promising applications in personal protective equipment, indoor air quality monitoring, environmental protection, and medical diagnostics.

The global issue of plastic waste accumulation may eventually be addressed through biological systems that break down plastics and utilize the resultant by-products. In the current study, we primarily focus on the practical applicability of these systems in real-world scenarios. We examined the differences between controlled laboratory condition (CC) and environmental-like controlled condition (ECC) for consumption efficiency, feeding behaviour, and the effect on larval health for plastic biodegradation assay. Plastic sample exposed to insects shows significant chemical modification in fourier-transform infrared spectroscopy (FTIR) spectrum suggesting oxidative and structural degradation. In-silico toxicity (PROTOX-3.0) results shows high probability for hepatotoxicity, mutagenicity, carcinogenicity, blood-brain barrier (BBB) permeability, and interactions with cytochrome P450 (CYP2C9) highlighting toxicity concern for ethylene. Molecular docking results shows strong binding affinities of several enzymes (oxidoreductases and hydrolases) with plastic polymers supports our findings, indicating potential role in degradation.

塑料废物积累的全球性问题最终可能通过分解塑料并利用由此产生的副产品的生物系统来解决。在目前的研究中，我们主要关注这些系统在现实世界场景中的实际适用性。在塑料生物降解试验中，我们研究了受控实验室条件（CC）和类环境控制条件（ECC）在消耗效率、摄食行为和对幼虫健康的影响方面的差异。在傅里叶变换红外光谱（FTIR）中，暴露于昆虫的塑料样品显示出明显的化学修饰，表明氧化和结构降解。硅毒性（PROTOX-3.0）结果显示其极有可能具有肝毒性、致突变性、致癌性、血脑屏障（BBB）渗透性以及与细胞色素P450 （CYP2C9）的相互作用，突出了乙烯的毒性问题。分子对接结果表明，几种酶（氧化还原酶和水解酶）与塑料聚合物具有很强的结合亲和力，这支持了我们的发现，表明它们在降解中具有潜在的作用。彗星分析表明，食用塑料会导致食用塑料的昆虫幼虫产生严重的遗传毒性应激。
