Violet phosphorus (VP) has been demonstrated to be a more stable phosphorene nanomaterial compared to black phosphorus (BP). However, current research has primarily focused on the toxic effects of BP, with limited information available regarding the toxicity of VP. This study comparatively analyzed the ecotoxicity and mechanisms of action of environmentally relevant concentration exposures of the common green algae Tetradesmus obliquus to BP and VP nanosheets. The results revealed that VP exhibited a greater growth inhibitory effect on the algae compared to BP, which was linked to disruptions in cell membrane function. Both BP and VP induced intracellular oxidative stress responses, yet they did not cause oxidative damage to algal cells. Transcriptional responses suggested that the number of differentially expressed genes in the algae exposed to VP was 29 times higher than that in the algae exposed to BP. Metabolomic analysis indicated that the number of differentially expressed metabolites induced by VP exposure in the algae was twice as high as the changes induced by BP. Furthermore, integrated transcriptome and metabolome analyses highlighted significant differences between BP and VP in core pathways, key metabolites, and driving genes. The findings of this study underscore the importance of considering the impact of different types of phosphorene materials when assessing their environmental risks.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"190 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133678","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}

In the present study, a novel green-synthesized Fe–Zn bimetallic nanoparticle (Fe–Zn BNP) was evaluated for Cd remediation and growth-promoting potential. Fourteen day-old indica rice seedlings were co-treated with 10 μM CdCl2 and Fe–Zn BNPs (25 mg L−1) for seven days and assessed for growth, stress parameters, and Cd content. Results indicated that Fe–Zn BNPs could effectively restore impaired growth parameters (root, shoot length, fresh and dry weight) and elevate chlorophyll and its precursor molecules (δ-ALA and PBG), eventually increasing photosynthetic efficiency by 72.21%. Significant reduction of ROS formation and other stress markers (MDA, methylglyoxal) were also observed. This study revealed a significant increase in Fe and Zn content upon treatment of Cd-stressed seedlings with Fe–Zn BNPs. Fe–Zn BNPs were found to restrict Cd localisation in root apices and reduce translocation from the root to the shoot by phytochelatin-mediated Cd sequestration (32.38% in the shoot and 42.39% in the root). Simultaneously, Fe–Zn BNPs downregulated the expression of Fe and Zn transporter genes OsIRT1, OsZIP1, and OsZIP4. Therefore, this research offers a promising avenue for the efficient amelioration of Cd toxicity in rice and improved plant health by developing a novel BNP.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"58 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127431","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}

While short-term nanomaterial exposure effects have been extensively studied, the multigenerational effects and potential transgenerational inheritance remain poorly understood. Here, we systematically investigated the biological effects of long-term nanomaterial exposure across multiple plant generations using Arabidopsis thaliana as a model system. Five chemically distinct nanomaterials (carbon dots, SiO2, TiO2, Fe3O4 and graphene oxide) were applied through root exposure for five consecutive generations (T1-T5), followed by a nanomaterial-free recovery generation (T6). Whole-genome sequencing revealed no detectable genetic alterations in ENM-parental-exposed T6 plants compared to the parental-unexposed T6 control ones. Strikingly, transcriptional profiling found significant changes in gene expression, and the expression differences almost align with the phenotypic traits observed in the nanomaterial-treated T1 generation. Phenotypic traits, such as enhanced biomass accumulation originally induced in T1 -T5 generations persisted in T6 plants despite nanomaterial withdrawal, suggesting the occurrence of transgenerational memory. Our findings provide the first experimental evidence that multigenerational exposure to these five nanomaterials induces no detectable genetic alterations but transgenerational memory in Arabidopsis thaliana, offering new insights for sustainable nano-agriculture development.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"89 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116312","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 aim of this research was to characterize and quantify titanium dioxide and zinc oxides nanoparticles (NPs) that were released from two commercial sunscreens into three aqueous matrices (ultrapure, hard and soft natural waters) after two short term exposures: ∼15 min and ∼60 min. An inductively coupled plasma time-of-flight mass spectrometer (ICP-ToF-MS) was used to detect elements with mass to charge (m/z) ratios ranging from 26 to 210 amu within single particles (SP). The elemental compositions, mass distributions and isotopic ratios (47Ti/49Ti and 66Zn/68Zn) of the individual NPs were investigated in order to determine to what extent it was possible to discriminate the natural and engineered NPs. The coupling of an ion-exchange resin to the ICP-ToF-MS resulted in a reduced background signal for zinc, leading to the detection of reasonably small zinc oxide nanoparticles (size detection limit of ∼53 nm on the ICP-ToF-MS). For both commercial sunscreens, Zn was primarily released as dissolved forms, with nearly all of the Zn found below the size detection limits or adsorbed to NNP after 60 minutes. Based upon the SP-ICP-ToF-MS results, the detected NPs in the sunscreens mainly contained single elements, in contrast with the natural NPs. Elemental ratios were helpful to distinguish the ENP from NP, but isotopic ratios (Ti or Zn) were not a distinguishing factor for the NP, in this case. Spearman rank analysis provided an additional index to distinguish the different particle types.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"8 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116311","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}

In this paper, the interactive toxicity of polystyrene (PS)-NPs and polylactic acid (PLA)-NPs with the typical Organic UV filters butyl methoxydibenzoyl methane (BM-DBM) on the intestinal health and metabolism of zebrafish (Danio rerio) was investigated at the tissue and molecular levels using wild AB zebrafish as a model organism. The results showed that both NPs and BM-DBM exposure alone or in combination induced different degrees of inflammatory symptoms in the zebrafish intestine, where PS and PS+B exposure groups also induced an imbalance of the zebrafish intestinal flora, causing a more severe intestinal inflammatory response than PLA and PLA+B. PS and PS+B also induced more metabolic pathways or differential metabolite alterations than PLA and PLA+B, respectively. The results of liver-related factor response showed that all exposure groups except PLA alone induced oxidative stress in liver tissue, and hepatic metabolic factors were also interfered with to varying degrees, with more severe organismal metabolic abnormalities induced in the PS and PS+B groups. The above reflected the liver friendliness of PLA, while highlighting the risk of hepatotoxicity of PS. Pearson correlation analysis proved that abnormal changes in metabolites such as lipids and lipid-like molecules due to changes in intestinal flora are most likely an important mechanism and cause of the abnormal response of intestinal and hepatic molecular indicators. We hope that our study will provide a basis for the ecological risk assessment of non-/biodegradable NPs and provide data support for the promotion of biodegradable plastics.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"89 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077541","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}

In vitro assays indicated that CDs-c had the highest scavenging activities against KMnO4, DPPH, ·OH, and O2- radicals. The changes in the morphology and chemical structure of these CDs after the reaction with ·OH suggested that the carboxy-like structures play significant roles in radical scavenging and antioxidant activity. Additionally, the calculation of reaction energy barriers using Density Functional Theory (DFT) revealed that the interaction between the carboxyl group and free radi-cals occurred in a barrier-free manner, resulting in the highest radical scavenging activity.

However, the effects of its structural parameters on membrane stability and oil-water separation performance remains unclear. This study performed molecular dynamics simulations to elucidate the underlying microscopic mechanisms. Results revealed that GO and PA spontaneously assembled into a stable sandwich-like membrane structure, wherein a highly oxidized lamellar GO framework enhanced PA accommodation. PA adsorbed robustly onto the GO surface through dense oxygen-containing functional groups, cross-liking adjacent GO sheets to precisely control interlayer spacing and suppress GO self-scrolling. Simulations further revealed that reduced GO oxygen coverage accelerated water permeation, while increasing the PA mixing ratio significantly improved oil-water separation performance, yielding a water flux of 4.1 molecules ns-1 and a separation efficiency of 96.3%. Energy analysis demonstrated that PA content dominated membrane hydrophilicity, imposing higher energy barriers for oil permeation than water. PA functionalization substantially enhanced the oil-water separation capability of GO membrane, with theoretical maxima reaching 97.5% separation efficiency and 98.8% water purity. These findings confirmed the dual role of phytic acid in stabilizing GO nanomembranes and promoting selective permeation of water and oil.

Since internalization is a prerequisite for inducing adverse effects, we investigated the roles of surface modifications and polymer composition in human liver cells (HUH-7). Our study compared the internalization and effects of a pristine polystyrene nanoplastic (PS50-NPLs), two carboxylated polystyrenes of different sizes (cPS50-NPLs and cPS100-NPLs), and two environmentally relevant nanoplastics derived from polyethylene terephthalate water bottles (PET-NPLs) and polylactic acid pellets (PLA-NPLs). Significant variations in cell internalization were observed, with cPS50-NPLs and PET-NPLs showing the highest levels, and PS50-NPLs the lowest. Interestingly, internalization alone did not correlate directly with the induced effects; only PET-NPLs and PLA-NPLs induced reactive oxygen species (ROS), genotoxicity, and increased cytokine release. These results suggest that while internalization is essential in assessing MNPL toxicity, harmful effects also depend on other particle characteristics. The notable impact of the true-to-life PET-NPLs and PLA-NPLs underscores the importance of using environmentally representative MNPLs to better assess the health risks associated with environmental MNPL exposure.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"155 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077556","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}
