Researchers have detected an understudied class of per- and polyfluoroalkyl substances (PFAS), known as fluorotelomer ethoxylates (FTEOs), in indoor dust and industrial wastewater samples collected across two provinces in Canada. They found the highest concentrations of FTEOs in dust found in healthcare settings, such as a hospital, a pharmacy, and a medical school, and in effluent produced at a healthcare linen cleaning facility (Environ.
