Organic Fluorine as an Indicator of Per- and Polyfluoroalkyl Substances in Dust from Buildings with Healthier versus Conventional Materials

A study investigated the presence of per- and polyfluoroalkyl substances (PFAS) in dust from buildings with “healthier” materials, finding lower PFAS contamination levels compared to conventional buildings, highlighting the importance of using chemical class-based methods for evaluating PFAS exposure.
