Results show that the fluorotelomer alcohol impaired the development of the blood–brain barrier and altered brain immune microenvironment, causing anxiety-like behavior and impairments in learning memory. Mechanistic studies suggest that this is due to the activation of the serine and threonine kinase AKT/nuclear factor kappa-b/matrix metalloproteinases signaling pathway, resulting in the degradation of the tight junction protein occludin, which in turn caused disruption of endothelial barrier function.

They contribute to the production of reactive oxygen species in environmental media, leading to oxidative stress in biological organisms. This stress can provoke inflammation and damage to biological macromolecules, potentially resulting in cardiopulmonary dysfunction. In this review, we discuss the formation and classification of EPFRs. Typically, EPFRs form through electron transfer from organic compounds to transition metals during thermal processes. In metal-free environments, however, organic compounds can undergo bond cleavage, generating EPFRs under thermal conditions and light exposure. EPFRs are generally categorized into three types: oxygen-centered, carbon-centered, and those containing heteroatoms centered on either oxygen or carbon. We also provide a detailed summary of the fundamental characteristics of EPFRs in different environments such as air, soil, and water. Given their role as electron donors, EPFRs have potential applications in degrading organic pollutants in the environment. The review comprehensively addresses the deleterious impacts of EPFRs on organism health, highlighting risks to metabolic functions and cardiopulmonary health. Furthermore, it underscores the potential involvement of EPFRs as electron donors in atmospheric chemical reactions. The pivotal role of EPFRs in environmental pollutant transformation warrants more studies in future research endeavors.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 3","pages":"1327 - 1343"},"PeriodicalIF":15.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139750215","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}

Depending on whether the cell had a porous or a smooth surface, microplastics adsorbed to the cell surface via embedding or denting, leading to minor defects or noticeable wrinkles in cell walls. Results also showed that microplastics penetrate into microalgae. Such cellular engulfment of microplastics was less present in typical diatoms because diatoms bear a porous frustule capable of trapping tiny particles. Moreover, we observed a novel type of deformation, bowl-shaped depressions, only in non-porous microalgae.

The addition of either cadmium or doxycycline decreased the glucokinase and glyceraldehyde-3-phosphate dehydrogenase activities, and their combined pollution had a higher impact on adenosine triphosphate than on nicotinamide adenine dinucleotide. Moreover, the activities of the electron transport system, nitrate reductase, and nitrite reductase were enhanced by short-term pollutant exposure, but inhibited by long-term pollutant exposure.
