Per- and Polyfluoroalkyl Substances (PFAS)

Per- and polyfluoroalkyl substances (PFAS) are dangerous contaminants in the environment and have attracted much public concern. Because of their unique physicochemical properties including surface active behaviour and chemothermal stability, they have been extensively used in numerous sectors of the economy. Their extensive use and ubiquitous discharge into the environment pose a potential risk to the ecosystem in general, and human health in particular. PFAS may undergo biotransformation after discharge, which makes monitoring their occurrence and transportation challenging. Despite precautionary legislation, reducing PFAS concentrations in water and wastewater to below health advisory levels requires…
