This study provides the first evidence that exposure to polystyrene nanoparticles (PS-NPs) induces a significant epitranscriptomic reprogramming, detecting 38 different tRNA mononucleotides and 49 oligonucleotides through a derivatization-LC-MS/MS approach. PS-NPs induced potent oxidative stress, marked by a 3.1-fold increase in reactive oxygen species (ROS) and a 2.6-fold increase in the RNA damage marker 8-oxo-GMP. Furthermore, this stress upregulated the acetyltransferase NAT10, leading to N4-acetylcytidine (ac4C) hypermodification that occurred specifically within the D-loop of tRNALeu under nanoplastics stress. Interestingly, NAT10/ac4C axis activation could also decrease the sensitivity to the chemotherapeutic agent sorafenib, increasing its IC50 from 6.9 μM to 25.7 μM. Crucially, this chemoresistance was reversed by both pharmacological inhibition (with Remodelin) and genetic knockdown (with siRNA) of NAT10, which subsequently ameliorated oxidative stress and re-sensitized the cells to sorafenib, confirming the pathway's causal role in modulating cellular response to nanoplastic exposure. Our findings establish the upregulation of the NAT10/ac4C axis as a targeted, adaptive response to nanoplastics-induced stress, revealing a direct mechanistic link between an environmental pollutant and impaired chemotherapeutic efficacy. This identifies the NAT10/ac4C axis as both a key mediator of nanoplastics toxicity and a promising therapeutic target to restore cellular health.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"102 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, the relative relevance of these two pathways for the occurrence and levels of QACS observed in surface waters is unknown. To resolve this issue, a process study was conducted on a small riverine system. QAC concentrations were below 0.1 ng/L during dry weather while they reached 90 ng/L during rainy weather. The concentration patterns of the parent QACs indicate that they originate mainly from surface runoff. Additionally, tributaries without wastewater treatment discharges delivered significant or even major QAC loads during rain events, also suggesting surface runoff from treated buildings as the predominant source. This interpretation is further solidified by using metoprolol as a marker for the river's wastewater fraction, thus calibrating a mass balance model. Both support the hypothesis that urban runoff dominates wastewater treatment plants as a source of QACs.On top of the parent compounds, QAC metabolites, originating from microbial degradation processes, were also detected.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"16 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 employed a comparative Partial Least Squares Path Modeling (PLS-PM) approach across four mangrove areas under a distinct anthropogenic pressure gradient in the Beibu Gulf. The models revealed a critical divergence: while sediment physical structure was the primary factor controlling the total distribution of HMs, their bioavailability was more intricately governed by a combination of sediment chemistry (salinity) and nutrient cycling (N, P). This fraction-controlled bioavailability, in turn, was a significantly better predictor of biological responses. For phytoaccumulation, while root uptake correlated with sediment bioavailability, the metal loads in aboveground tissues were largely decoupled from sediment conditions, challenging risk assessment paradigms based solely on sediment data. For microbial communities, their structure was more strongly associated with metal bioavailability than total concentrations, with these bioavailable fractions appearing to exert selective pressure on key taxonomic groups. This study demonstrates that a fraction-centric approach, which separates the drivers of distribution from those of bioavailability, is essential for mechanistically understanding and accurately managing HMs risks in coastal wetlands.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"49 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Passivator addition significantly reduced total As, arsenite (As(III)) and arsenate (As(V)) in soil porewater and As accumulation in rice plants. The abundances of sulfate-reducing gene (dsrA) increased by 136-225% and the functional microorganisms (e.g., Clostridium and Bacillus) were also increased with passivator amendment. The spatial distribution of As across the rhizosphere microzones exhibited strong distance-dependent mobility patterns. Total As, As(III) and As(V) increased from root-proximal (0-2 mm) to far-rhizosphere (8-10 mm) zones by 36-83%, 36-110%, and 28-397%, respectively. The abundances Geobacter and dsrA gene peaked in the root-proximal zone (0-2 mm) with passivator addition, driving As sequestration. These findings highlight that sulfur-based passivator amplifies rhizosphere effects through sulfur-iron interactions, establishing a sulfate-iron reduction-dominated As immobilization pathway.

This study investigated the effects of perfluorooctanoic acid (PFOA), a representative PFASs, on the combustion behavior of model organic sulfur compounds—sulfone (S) and mercaptan (M). The combustion of S/M–PFOA mixtures was primarily governed by the organic sulfur species, with PFOA reducing the heat threshold required for sustained combustion. The presence of PFOA enhanced the mineralization of organic sulfur, leading to significant emissions of SO₂, CH₃SH, and HF. The yields of CH₃SH and SO₂ from the mixtures increased by 1.11–5.58 and 1.30–6.34 times, respectively, compared with the organic sulfur alone, attributable to a “Trojan Horse” effect involving coupled radical and secondary reactions. PFOA lowered the binding energies of the mixtures by 26.55–62.57%, effectively reducing the combustion barrier of organic sulfur. The low formation energies of S–PFOA (–872.21 kcal/mol) and M–PFOA (–729.70 kcal/mol) confirmed the spontaneous and synergistic combustion of PFAS–sulfur mixtures. Overall, PFASs act as a “Trojan horse,” intensifying sulfur-related emissions during DS incineration.

A total of 21 PFAS were detected, with Σ21PFAS concentrations ranging from 2.69 to 97.0 ng/L.

PFAS levels varied notably across product types, water sources and treatment. Spring water showed the highest average Σ21PFAS concentration (37.5 ng/L), likely due to shallow, surface-impacted sources and minimal treatment. In contrast, lower levels were observed in mineral and purified waters, especially those from deeper aquifers or with reverse osmosis (RO) treatment. Risk quotient analysis indicated that, apart from PFOA and PFOS, most PFAS posed low to very low health risks under existing guidelines.

Recently, monitored natural purification, though eco-friendly, suffers from slow remediation rates. Here, we report an innovative approach through regulating endogenous iron cycle and hydroxyl radical (•OH) productions to accelerate natural soil purification while maintaining soil functionality. By periodically adding mild concentrations of H2O2 to activate soil iron minerals, we triggered an endogenous Fenton-like reaction, resulting in a significant 10.4-fold increase in •OH generation. Simultaneously, oxidized iron was regenerated through microbial reduction, completing the biogeochemical redox cycles of iron. Over five cycles of these redox processes, pollutant removal rate was enhanced by 6.3-fold, achieving >95% phenol degradation. Compared to chemical remediation, this approach reduced organic matter loss by 91% and preserved 96% microbial activity. Furthermore, treated soils maintained fertility, supporting vigorous lettuce and cabbage growth. To further advance this system, we developed an on-site H2O2 production system powered solely by sunlight, water, and air, eliminating the need for additional energy or chemical inputs. This integrated system demonstrates the potential for accelerated and sustainable soil remediation.

CL-600 demonstrated a maximum removal efficiency of 5.56-log10 for PhiX174, significantly surpassing the 0.58-log10 of unmodified ceramsite. This removal was dosage-dependent while overcoming the agglomeration issues common to traditional materials. Moreover, CL-600 maintained high inactivation across pH 5-9, even under high viral loads or natural organic matter. The primary inactivation mechanism of CL-600 was identified as adsorption-enabled contact inactivation at surface La sites. Structural analysis revealed damage to the capsid proteins, including proteins A, F, H and G. Furthermore, DNA exposure led to damage to nine pairs of functional genes, with the most significant damage corresponded to gene H. Collectively, these structural damages disrupted viral attachment, injection, and replication functionalities and leading to reduced infectivity.

This study evaluated the impact of four common MPs with varying degrees of UV aging on oil spill behavior, focusing on their roles in the formation of MPs-oil agglomerates (MOA), oil dispersion and sedimentation. MPs and oil primarily undergo agglomeration through interactions between hydrophobic and van der Waals forces. UV aging reduced the degree of agglomeration between MPs and oil. The aged MPs had more oxygen-containing functional groups and more negative potential. These properties enhanced electrostatic repulsion while decreasing hydrophobic and van der Waals interactions. Aged MPs promoted oil dispersion, and the oil dispersion efficiency increased by 6.6-13.7% while inhibiting oil sedimentation. The types and aging degrees of MPs were found to significantly affect their interaction with the oil, which further affected the transport behavior of oil spills in the water column.
