FAS is a very large group of polyfluoroalkyl substances that is widespread in the aquatic environment, as a result from a broad range of uses in different products. PFAS range from small molecules to large plastic polymers as Teflon and the carbon-fluoride bond makes these substances slowly degradable in nature, so most of the compounds can be characterized as Persistant Organic Pollutants (POPs). The knowledge of the fate and dispersion of these compounds is still incomplete, and this is the background for the findings presented here as a little contribution from the STEP project on the matter, also pointing out what further work will be relevant to do with regard to sludge.
