Recently, engineered nanomaterials (ENMs) have been developed to enhance plant growth and address the global food crisis. Studies on the effects of nanomaterials mostly indicate an increase in the spread of antibiotic resistance, while emerging findings reveal the potential of ENMs in mitigating ARG pollution. Unlike existing mechanisms such as adsorption, DNA damage, and microbial disinfection involved in ARG removal, ENMs are specifically modified (e.g., with particular chemical compositions or surface charge adjustment) to inhibit the transfer of ARGs and migration of antibiotic-resistant bacteria. The integration of ENMs with advanced technologies (e.g., CRISPR gene editing) holds great promise for remediating antibiotic resistance in soil-plant systems. Here, we provide an overview of ENM-ARG interactions and propose applications of tailored ENMs to inhibit ARG dissemination during the development of nano-enabled agriculture, addressing major challenges and directions for optimizing efficacy and safety of ENMs-based strategies for mitigating ARG contamination in agriculture.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"35 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031249","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 autocatalytic interaction between hematite and Fe(II)-oxalate has long been of interest for its environmental and industrial relevance. In this study we take advantage of iron isotopic labelling and mass-sensitive imaging at the single particle scale to determine how changes in solution composition correlate with the morphologic evolution of faceted, micrometer-sized hematite platelets. Net dissolution is confirmed through analyses of aqueous iron chemistry, as well as by quantitative atomic force microscopy. Isotopic mapping techniques show that Fe(II) readily adsorbs to (001) and (012) surfaces in the absence of oxalate, but when oxalate is present selective dissolution of the (001) surface prevails and 57Fe deposition via recrystallization is not observed. Comparison between particle microtopographies following reaction with Fe(II), oxalate, and Fe(II)-oxalate show substantially different behavior, consistent with distinct mechanisms of interaction with hematite surfaces. The extensive characterization conducted on the coupled solution/solid dynamics in this system provides new insight for distinguishing crystal growth, dissolution, and recrystallization processes.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"18 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026770","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 context, road traffic is a significant factor in the contamination of the urban environment in general, and runoff in particular. Some metals, such as Cu, Zn, Fe, and Ti, have been found in dissolved fraction (< 0.45 μm) in such water. The present study focuses on characterizing the number concentration and mass distribution of nanoparticles (NPs) containing Ti, Fe, Zn, and Cu in runoff from a heavily trafficked urban motorway (≈ 100,000 vehicles/day) in Nantes, western France. Seven runoff samples were taken between July 2023 and March 2024. A rainfall sample was also taken in the same proximity for comparative purposes, providing knowledge of atmospheric wet deposition levels. Using two sample preparation methods, filtration, and ultra-filtration, single particle ICP-MS (sp-ICP-MS) analysis confirmed the existence of the targeted elements in nanoparticulate fraction. Ti was found to be the most abundant element, followed by Fe, while Zn and Cu were less prevalent, with average number concentrations of 4.83 x 10^8, 1.68 x 10^8, 7.78 x 10^7 and 9.04 x 10^7 particles/L, respectively. Except for Fe, runoff samples exhibited higher concentrations of Ti, Zn, and Cu nanoparticles compared to the rainfall sample, with a larger average equivalent diameter indicating a likely anthropogenic origin. Comparisons between sample preparation methods demonstrates that the effectiveness of ultrafiltration is element dependent.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"45 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020407","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 significance of the difference between them was determined by the McNemar test. The mean number of visible LAG counted from the humerus is greater than the mean number of visible LAG counted from the phalanx, i.e., the humerus contains more growth marks than the phalanx. However, in individuals up to 15 LAG in C. mydas and 10 LAG in C. caretta, the mean number of visible LAG observed in both bone tissues is compatible. This was supported by the differences in the resorption rates calculated in both bones, indicating that the number of LAG lost due to resorption may also differ between these two bone types.

Subsequently, Co(II)-PIIMs-x nanofibers were fabricated via electrospinning. Co(II)-SIM-IIP were incorporated as fillers, while PAN was used as the substrate, aiming at selectively separating cobalt ions. Optimal performance was achieved with a 10% doping level of Co(II)-SIM-IIP, resulting in adsorptive capacity peaking at 112.74 mg/g, along with membrane flux of 1095 L/m² h, and a retention rate of 43.49%. The material exhibited excellent selectivity with high selectivity factors for various ions such as Ca2+ (7.42), K+ (55.98), Mg2+ (72.30), and Ni2+ (1.28). Adsorption mechanism results indicated that cobalt adsorption by Co(II)-PIIMs is governed by the adsorption rate control step and the even distribution of cobalt on the surface, aligning with chemisorption properties. After five adsorption-desorption cycles, Co(II)-PIIMs demonstrated excellent regeneration capability, maintaining over 95% of their initial adsorption capacity. These impressive selectivity factors underscore the material's capability to selectively adsorb cobalt ions over other competing ions, making it a promising candidate for efficient separation and purification processes in environmental remediation applications.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"11 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992327","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}

This study evaluated the effects of exposure to naturally-aged polyethylene terephthalate (PET) microplastics on <i>Physalaemus cuvieri</i> tadpoles to investigate particle retention and toxicological impacts after cessation of exposure. The MPs were characterized through scanning electron microscopy and Raman spectroscopy analysis, and the weathering action was confirmed. Furthermore, our results indicated a significant increase in the mortality of tadpoles exposed to PET-MPs and partial retention of MPs after depuration. A higher Redox Balance Index (involving ROS levels and SOD and CAT activity) observed in the PET-MPs group at the end of the depuration period reveals a greater redox imbalance in these tadpoles. On the other hand, exposure to MPs induced neurochemical dysfunctions, such as reduced dopamine levels and increased AChE/BChE ratio, which were evident even after the end of exposure. Furthermore, the increase in total protein levels was observed throughout the experiment only in the control group. Finally, multivariate analyses (PCA and discriminant analysis) confirmed the occurrence of a phenomenon called the “legacy effect,” showing a clear separation between groups in the distinct phases of the experiment. In addition, multivariate linear regression analysis revealed a significant influence of MPs on the response of the animals only at the end of the exposure period, suggesting that the response observed at the end of depuration was cumulative, reflecting the damage induced during exposure. Thus, it is concluded that exposure to naturally-aged PET-MPs generates cumulative toxic effects in P. cuvieri, even after removing the pollutant, reinforcing the need for mitigation strategies to minimize the prolonged impacts of MPs on aquatic ecosystems.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995609","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}
