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.
