Structures of the representative per- and polyfluoroalkyl substances (PFAS) discussed in this article. Short-chain PFAS are represented by perfluorobutane sulfonate (PFBS) and perfluorobutanoic acid (PFBA). Long-chain PFAS are represented by perflourooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Next generation PFAS are represented by GenX. For a more inclusive view of PFAS structures see Shaw et al., 2019 and Xiao, 2017 [5,6].
