I’m guessing that you mean as a preservative?

If so, no: the article is about a technique for destroying long-lived PFAS molecules, which are extraordinarily stable and therefore long lived, and about which there are health concerns (they do very odd things to biological systems in very low concentrations).

Linked in the article is the research paper detailing the technique: https://www.nature.com/articles/s44172-024-00267-4
