Environmental context Per- and polyfluoroalkyl substances (PFASs), often called ‘forever chemicals’, have contaminated water sources worldwide and pose serious health risks. This study reviews how adsorption technologies – using materials such as activated carbon and advanced nanomaterials – can effectively capture and remove PFASs from water. These insights support the development of safer, more efficient treatment solutions and guide future policies to protect public health and the environment. Abstract Per- and polyfluoroalkyl substances (PFASs), a large and chemically diverse group of synthetic fluorinated compounds, have been extensively used in industrial processes and consumer products due to their remarkable thermal stability and resistance to degradation. However, their environmental persistence, bioaccumulation potential and associated health risks are of growing global concern, especially given that PFASs have been detected in over 98% of the US population and in ecosystems worldwide, with estimated environmental half-lives spanning decades to centuries. This review critically and comprehensively synthesises current knowledge on PFAS production, environmental dissemination and management strategies. It explores major contamination sources and pathways, highlights their global distribution and examines the evolving regulatory landscape. The review focuses on adsorption-based removal technologies, in-depth evaluating mechanisms of PFAS interactions with adsorbents su...
