Bioaccumulation of PFAS: PFASs from sediments and water can accumulate in marine organisms. Animals higher up the food chain accumulate more PFAS because they absorb PFAS in the prey they consume. In marine species of the food web. Bioaccumulation controls internal concentrations of pollutants, including PFAS, in individual organisms.
An example of PFAS is the fluorinated polymer polytetrafluoroethylene (PTFE), which has been produced and marketed by DuPont under its trademark Teflon. GenX chemicals and perfluorobutanesulfonic acid (PFBS) are organofluorine chemicals used as a replacement for PFOA and PFOS.
Perfluorodecanoic acid (PFDA) is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature. Over the last decades they have been used in consumer products and industrial applications.
