Per- and polyfluoroalkyl substances (PFAS) transport refers to the movement of these man-made chemicals through various environmental media, such as air, water, soil, and biota. PFAS are a group of synthetic compounds that are widely used in consumer products, industrial processes, and firefighting foams. Due to their persistence and bioaccumulative nature, PFAS have been found to contaminate the environment and pose potential risks to human health. Research in this area focuses on understanding the fate and transport mechanisms of PFAS in different environmental compartments, as well as assessing the potential risks and impacts of PFAS contamination on ecosystems and human populations. This research is important for developing effective strategies for managing and remedying PFAS contamination in the environment.
