Is comhdhúile ceimiceacha sintéiseacha orgánafluairín iad substaintí sár- agus polafhluarailcile (SSPF) (Béarla: Per- and polyfluoroalkyl substances (PFASs)) a bhfuil adaimh iolracha fluairín acu ceangailte le slabhra ailcile . Mar sin, tá ar a laghad earra sárfhluarailcile amháin iontu,–C n F 2n –. [1] [2]

De réir na hEagraíochta um Chomhar agus Fhorbairt Eacnamaíochta (ECFE): [3] [4]

PFASs are defined as fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom (without any H/Cl/Br/I atom attached to it), i.e. with a few noted exceptions, any chemical with at least a perfluorinated methyl group (–CF3) or a perfluorinated methylene group (–CF2–) is a PFAS.
