Per- and polyfluoroalkyl substances (PFAS) are a broad class of synthetic organofluorine compounds characterized by carbon chains that are fully or partially fluorinated, conferring exceptional thermal, chemical, and surfactant stability. As a research topic, PFAS encompasses their environmental persistence, bioaccumulation, complex transport and transformation pathways, and emerging toxicological profiles, including interactions with lipid metabolism, endocrine signaling, and immune function. Investigations address analytical challenges in ultra-trace detection, structural diversity (e.g., legacy vs. replacement PFAS), mixture effects, and the development of remediation technologies and regulatory frameworks, making PFAS a central focus in environmental chemistry, exposure science, and risk assessment.
PFAS, short for per- and polyfluoroalkyl substances, are not called "forever chemicals" for nothing. These fluorine-containing organic molecules are difficult to break down and are likely to remain in the environment for ...

Eating fish may well be good for you, but it carries a hidden risk of exposure to so-called "forever chemicals." A new study published in the journal Science has revealed that the global seafood trade is acting as a massive ...
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
