Recent advances in nonthermal plasma (NTP)-enabled processes have yielded remarkable results and progress in the remediation of Per- and polyfluoroalkyl substances (PFAS), especially in the past three to five years. In comparison to typical chemical oxidation and reduction reactions that are conducted in bulk aqueous solutions with specific reactive oxidative or reductive species, the reported NTP-based PFAS degradations occur mainly at the water–bubble/air interface and increasingly in the bubble interiors. Further, the degradations occur simultaneously in the presence of a multitude of oxidative and reductive species, including radical, ion, photon, and hydrated electron species. These aspects have introduced some interesting science in such PFAS degradations. This opinion highlights such examples by both illuminating their salient features and more importantly proposing perspectives with respect to the observed science.

非热等离子体（NTP）工艺的最新进展在全氟烷基物质和多氟烷基物质（PFAS）的修复方面取得了显着的成果和进展，特别是在过去的三到五年里。与在具有特定活性氧化或还原物质的本体水溶液中进行的典型化学氧化和还原反应相比，报道的基于 NTP 的 PFAS 降解主要发生在水-气泡/空气界面，并且越来越多地发生在气泡内部。此外，降解在多种氧化性和还原性物质（包括自由基、离子、光子和水合电子物质）存在下同时发生。这些方面在 PFAS 降解方面引入了一些有趣的科学知识。该观点通过阐明这些例子的显着特征，更重要的是提出了与所观察到的科学相关的观点来强调这些例子。
