Organic pollutants like per- and polyfluoroalkyl substances (PFASs) exhibit persistence, bioaccumulation, resistance to degradation, high toxicity, garnering significant attention from scholars worldwide. To better address mitigate the environmental risks posed by PFASs, this paper employs bibliometric analysis examine literature on PFASs' concentrations collected in Web of Science (WoS) database between 2019 2024. The results show that overall trend pollution research is relatively stable increasing. In addition, study also summarizes status traditional PFASs across different media typical freshwater basins. It analyzes surface water, sediment, aquatic organisms, elucidating their distribution characteristics potential sources. While perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS) levels water environments are declining annually, short-chain substitutes emerging as primary pollutants. Short-chain frequently detected whereas long-chain tend accumulate sediments. more likely concentrate protein-rich organs tissues. presence largely influenced human activities, such metal plating, fluoride industry development, industrial wastewater discharge. Currently, development China faces a complex dilemma, entangled policy legal constraints, production demands, use new alternatives, regulation restriction, creating vicious cycle. Breaking deadlock necessitates continuous active scientific particularly PFOS, with an emphasis detailed investigations sources sinks. Furthermore, ecological health risk assessments were conducted using Risk Quotient (RQ) Hazard (HQ) methods. Comprehensive comparison indicates (such PFOA) majority basins at low-risk level (RQ < 0.1 or HQ 0.2), PFOS some medium-risk (0.1 RQ 1), no basin high-risk level. adsorption removal approaches analyzed, revealing combination multiple treatment technologies novel integrated technology holds excellent prospects for PFASs.

Cytotoxic antibiotics (CA) present a pressing environmental concern due to their persistence and potential adverse effects on ecosystems human health. Conventional wastewater treatment methods often fail effectively remove these compounds, making it necessary explore advanced oxidation processes (AOPs) as promising alternatives. This review aims synthesize global data the dosages concentrations of common CA in diverse water sources, while evaluating efficacy AOPs degrading contaminants. Various AOPs, including photocatalysis, ozonation, Fenton-like processes, or combination, are discussed, highlighting mechanisms efficiency eliminating cytotoxic from aqueous environments. In addition, information about degradation by-products is provided. The rising consumption drugs underscores need for this up-to-date review, diseases were used treatment, show increasing numbers. By consolidating recent developments outlining challenges opportunities, serves valuable resource researchers, engineers, policymakers involved mitigating impact through AOPs.

Upcoming regulations aim to ban per- and polyfluoroalkyl substances (PFAS), including commercial polymeric PFAS, or fluoropolymers, such as poly(tetrafluoroethylene) (PTFE) poly(vinylidene fluoride) (PVDF), due their environmental toxicological impacts. However, fluoropolymers also provide crucial properties for clean energy transitions, regulation may hinder further technological advancements. Therefore, a facile one-pot recycling–upcycling strategy using inexpensive biomass, cellulose nanocrystals (CNCs), absorbents cocomponents fluoro-functionalized composites could align with global sustainability goals demands. Herein, we present closed-loop CNC-in-solvent (CiS) processing system, which involves stirring CNCs in only low-polarity solvents like toluene (CiS-T). Our study reveals that CiS-T is two-step process where the CNC–solvent interaction exposes CNCs' reducing end aldehyde protons solvent polarity promotes H–F bond formation. The used was recollected reused. Additionally, demonstrate practical application of PTFE– PVDF–CNC hybrids, byproducts process, performance-enhancing agents green-energy-harvesting devices triboelectric nanogenerators. findings not offer sustainable method overcome challenges from against but insights into developing an efficient, solvent-mediated CNC functionalization addresses forthcoming key industries.
