Here, six‑week‑old male mice were exposed to 125 mg/L 80 nm polyethylene nanoplastics, polyethylene nanoplastic/azoxymethane, polyethylene nanoplastics/azoxymethane/dextran sulfate sodium, and controls for 66 days. We assessed intestinal symptoms, colorectal tumorigenesis, and pathological, ultrastructural and molecular changes. Results show more colon tumors, of 18.3 versus 13.5, and heavier tumor burdens, of 113.1 versus 67.7 mm<sup>2</sup> in the mice treated with nanoplastics/azoxymethane/dextran sulfate sodium. Similarly, there were more colon tumors, of 6.0 versus 2.2, and heavier tumor burdens, of 26.0 versus 7.0 mm<sup>2</sup> in mice treated with nanoplastics/azoxymethane. Mice treated with nanoplastics alone developed colorectal neoplasms, of 2.9, with tumor burdens of 10.6 mm<sup>2</sup> and a pathology of polyp. Exposure to nanoplastics promoted tumor‑associated macrophages infiltration; disrupted microvilli, intercellular junctions, and the mitochondrial structures of colonic epithelium; and activated inflammation‑associated signaling pathways. Overall, the exposure to polyethylene nanoplastics facilitates the initiation and promotion of colorectal tumorigenesis, possibly by affecting mitochondrial structure and aggravating chronic colitis.</p>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"16 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560605","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 performance and the identification of degradation products were assessed by nuclear magnetic resonance and high-performance liquid chromatography. Results show the generation of several oxidizing agents such as hydroxyl radical, carbonate anion radical, and superoxide. The novel aspect is that the Fenton-like process can be achieved with Mg<sup>2</sup>⁺ serving only as a template to facilitate redox reactions rather than participating directly. The mechanisms for generating oxidizing radicals suggests potential applications in both environmental cleanup and biological processes.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 3","pages":"777 - 781"},"PeriodicalIF":15.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10311-025-01828-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, jet fuel consumed by the aviation industry is 1.5–1.7 billion barrels per year, resulting in 705 million metric tons of carbon dioxide emissions. Aircraft manufacturers have set ambitious goals, aiming for carbon-free growth post-2020 and a 50% reduction in greenhouse gas emissions by 2030. This issue can be solved by replacing fossil fuels with biofuels produced from modern biomass, thus meeting the carbon neutral objective. Here, we review the technologies to convert biomass into jet biofuel with focus on reactants, catalysts, and the chemistry of combustion. Reactants include alcohols, oil, esters, fatty acids, gas and sugars. Catalysts include Fischer–Tropsch catalysts, palladium, platinum, ruthenium, nickel, and molybdenum. The utilization of jet biofuels could potentially reduce greenhouse gas emissions by up to 80%. We also discuss economic implications.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 2","pages":"419 - 461"},"PeriodicalIF":15.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10311-024-01806-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
