The electrode properties and treatment performance were evaluated using actual coking ROC, and the effects of La doping, anode pore size, reactor configuration, initial pH, current density, and flow rate were systematically investigated. The results showed that La doping increased the oxygen evolution potential from 2.17 to 2.33 V (vs. SCE) and enhanced the electrocatalytic performance of the filtration anode. The optimal system consisted of a 1.6% La-doped filtration anode with a pore size of 20 μm and a two-stage flow-through reactor. Under the optimized conditions of an initial pH of 6, a current density of 15 mA/cm², and a flow rate of 48 mL/min, the COD and TOC removal efficiencies reached 71.6% and 63.18%, respectively, after 240 min, with an energy consumption of 21.8 kWh/m³. Radical-scavenging experiments indicated the involvement of ·OH and ·O₂⁻ in the oxidation process, with ·OH showing a stronger apparent influence under the tested conditions. The COD removal efficiency decreased by only 2.0 percentage points over six consecutive cycles and remained at 60.5% after 40 cycles. These results demonstrate that the developed La-doped filtration anode coupled with the multistage flow-through reactor provides a promising approach for the advanced treatment of refractory industrial wastewater.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"237 24","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microplastics and nanoplastics (M/NPs) can interact with metal ions (MIs) and metal-based nanomaterials (NMs), creating co-exposure scenarios whose effects cannot be inferred from individual stressors alone. As primary producers and sensitive bioindicators, microalgae are particularly vulnerable to these mixtures. Using a microalgae-centred conceptual Adverse Outcome Pathway (AOP) network, this Review organizes evidence from upstream exposure modifiers through biological key events (KEs) to adverse outcomes. Beyond previous reviews that mainly considered M/NP–metal interactions, algal toxicity or data-driven prediction separately, we integrate physical particle effects, endogenous plastic leachates and adsorbed exogenous metals within one mechanistic framework and link them to KE-related endpoints and machine-learning-ready descriptors. Single and combined exposures are compared to identify shared and stressor-specific mechanisms, with oxidative stress and photosynthetic impairment emerging as central KEs. Particle-induced shading and adhesion, ageing, aggregation, metal speciation and dissolution, extracellular polymeric substance (EPS) production and eco-corona formation are evaluated as processes that alter the cell-accessible dose. Enhanced toxicity is favoured when plastic particles increase local metal delivery or when co-stressors converge on oxidative and photosynthetic pathways, whereas strong sorption, heteroaggregation, sedimentation and EPS-mediated extracellular sequestration can reduce cellular metal exposure and attenuate toxicity, including antagonism where this is demonstrated against an explicit additivity model. We further assess machine-learning and deep-learning applications and map model inputs and outputs to upstream descriptors, intermediate KEs and downstream outcomes. Priorities include environmentally realistic mixture designs, quantitative exposure characterization, multi-species and trophic-level validation, and standardized datasets for AOP-aligned, ML-supported assessment of M/NP and metal co-pollution.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"27 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, information on its occurrence in agricultural soils, transfer to soil biota, and environmental behavior under field conditions remains limited for North African agroecosystems. This study investigated chlorpyrifos-ethyl contamination in intensive potato-growing systems of Larache Province through an integrated experimental and computational approach. Soil and earthworm samples collected from ten agricultural fields were analyzed by GC–ECD following QuEChERS extraction, while quantitative structure–activity relationship (QSAR) models implemented in the VEGA platform were used to obtain descriptive estimates of physicochemical properties, environmental fate, bioaccumulation potential, and earthworm toxicity. Chlorpyrifos-ethyl was detected in soils at concentrations ranging from not detected to 0.0965 mg kg⁻¹ and in earthworms from 0.0078 to 0.0440 mg kg⁻¹, indicating exposure of soil organisms at the sampled fields. Bioaccumulation factors ranged from 0.18 to 2.65, indicating variable field accumulation among sampling sites. Among the ten investigated fields, seven exhibited risk quotients (RQ) above 1, suggesting potential ecological concern under the specific conditions and dates sampled; given the single-composite sampling design and the limited number of fields, this observation should be regarded as a preliminary field-level indication rather than a regional risk characterization. QSAR predictions consistently characterized chlorpyrifos-ethyl as a highly hydrophobic compound (LogKow = 5.32) with strong soil sorption (logKOC = 3.62), low water solubility (1.26 mg L⁻¹), moderate soil persistence (half-life = 13 days), limited biodegradability, and considerable bioaccumulation potential (logBCF ≈ 3). This intrinsic bioconcentration potential contrasts with the generally low field-derived BAF values, a pattern that likely reflects the distinction between standardized, intrinsic bioconcentration (BCF) and realized, bioavailability-limited field accumulation (BAF), rather than a direct inconsistency between the two lines of evidence. Overall, integrating field monitoring with QSAR-based environmental prediction provides a comprehensive framework for evaluating pesticide behavior and ecological risk and supports the development of sustainable pesticide management strategies in intensive agricultural systems.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"237 24","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected 73 surface soil samples and applied an integrated approach including geostatistics, correlation analysis, Principal Component Analysis (PCA), and the Positive Matrix Factorization (PMF) model. Descriptive statistics indicated moderate HM levels but widespread enrichment compared to background values.

Spatial analysis revealed high concentrations of Cr and Ni in southern mountainous areas (natural origin), while Cd and Hg hotspots were associated with industrial and agricultural zones. The potential ecological risk was generally low, but Cd and Hg were the primary risk contributors, with 33.8% and 47.0% of samples posing moderate ecological risk, respectively. The PMF model quantified four primary sources: natural sources (57.0%), natural-agricultural mixed sources (18.3%), industrial-traffic sources (12.9%), and agricultural-industrial mixed sources (11.7%).

This review critically analyzes 113 experimental studies published from 2017 to August 2026 on nanomaterials (NMs) applied to tomato (Solanum lycopersicum), emphasizing relationships among physicochemical properties, dose, delivery route, mechanisms of action, efficacy, and phytotoxicity. The evidence is organized into four functional categories: nanofertilizers and nanobiostimulants, nanopesticides and stress-mitigation agents, nanocarriers and controlled-release systems, and phytotoxicity/ecotoxicology. Beneficial responses involve nutrient delivery and ion release, improved nutrient bioavailability, photosynthetic and metabolic stimulation, direct antimicrobial activity, defense activation, and mitigation of abiotic and chemical stress. Nanocarriers can also enhance the delivery and release of nutrients, phytohormones, nucleic acids, and pesticidal compounds. However, responses strongly depend on concentration, particle size and morphology, surface chemistry, coating, dissolution behavior, exposure conditions, and environmental context. Evidence remains uneven across laboratory, greenhouse, and field studies, and environmental transformations are still poorly characterized. Safer application will require function-specific dose optimization, rigorous characterization, mechanistic validation, and greater field-scale assessment. Ultimately, the information presented herein will provide researchers with directions to address research gaps and enable the integration of nanotechnology as a tool for sustainable tomato agriculture.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"232 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the commodity plastics, polyethylene terephthalate (PET) - extensively used in single-use bottles and textiles - exhibits hydrolytic stability and mechanical resilience, making it more resistant to natural degradation but extremely problematic for long-term persistence as MPs and NPs. In this study, photocatalytic degradation of PET MPs and NPs is investigated using hematite nano-ellipsoids (~ 250 nm major axis and ~ 50 nm minor axis) as the photocatalyst under visible light illumination. For this study, commercial PET granules are converted into NPs (~100 nm) via flash nanoprecipitation (FNP). The extent and efficiency of PET degradation is systematically evaluated using PET NPs of 100 nm under visible light irradiation at neutral pH, which exhibited mean 42±0.4% mass loss over 8 hours, with a reduction in particle size from 100 nm to ~10 nm. PET MPs (~100 μm) photocatalytic degradation exhibited 32±0.4% of weight loss and an overall particle size reduction from 100 μm to 0.8 μm after 8 days. The photocatalytic degradation of PET due to reactive oxygen species is found to be faster for NPs compared to MPs due to the higher specific surface area of NPs. These results establish HNEs as a highly effective and environmentally benign photocatalyst for accelerating PET micro- and nanoplastic degradation, offering a low-complexity and scalable platform for advanced plastic remediation applications.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"188 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal BCBS preparation condition was mixing BC with BS in deionized water for 1 h, resulting in a sulfur content of 48.6%. Elemental analysis, SEM–EDS, FTIR, XRD, and XPS were used to characterize BCBS and investigate the adsorption mechanisms before and after metal uptake.

Newly emerged bees were exposed to sugar syrup containing 12.5, 25, and 50 mM lithium citrate. Mortality increased monotonically with dose: 10-day survival was 0.94 in the control and 0.84, 0.22, and 0 at 12.5, 25, and 50 mM, respectively (all pairwise contrasts significant, Benjamini-Hochberg correction). Histological analysis of the midgut revealed pronounced epithelial damage, characterized by severe desquamation and cellular shedding into the lumen, even at the lower dose of 12.5 mM, with the highest severity at 12.5 mM rather than 25 mM; the peritrophic membrane remained intact in all groups. Furthermore, 16S rRNA gene sequencing revealed variation in the relative abundance of several core gut bacteria across treatment groups, although neither alpha- nor beta-diversity differed significantly among groups. At the highest lithium concentration (25 mM), <i>Gilliamella</i> showed a markedly lower median relative abundance, whereas <i>Frischella</i> was relatively more abundant; however, these patterns were not statistically supported by differential abundance analysis and did not indicate a consistent concentration-dependent response.

However, the rational integration of these two functions at the electrode level is fundamentally constrained by the divergent material requirements for efficient faradaic ion storage and robust electrocatalytic oxidant generation. Here, we demonstrate that sub-nanometer iron nanoclusters (Fe NCs) spatially confined within a zeolitic imidazolate framework (ZIF-67) via a pore-mediated vapor diffusion (PVD) strategy reconcile these competing demands within a single electrode architecture. The nanoconfinement of Fe NCs within the ZIF-67 micropores serves a dual purpose: it drastically shortens the solid-state chloride-ion diffusion pathways, enabling ultrafast faradaic charge storage with exceptional cycling stability, while simultaneously creating highly active catalytic sites for the continuous in situ electro-generation of reactive oxygen species (ROS) and reactive chlorine species (RCS). Of note, the electrode operates as a “capture-and-kill” platform, wherein negatively charged bacteria are electrostatically enriched at the anode surface and subsequently eradicated by the locally generated oxidative species, with dead cells desorbing during electrode regeneration. The optimized Fe NCs@ZIF-67 electrode delivers a competitive desalination capacity of 49.3 mg g-1, an ultrafast desalination rate of 0.31 mg g-1 s-1, and nearly 100% capacity retention over 20 cycles, while achieving the efficient inactivation of Escherichia coli.
