Substaintí sár- agus polafhluarailcile

Is comhdhúile ceimiceacha sintéiseacha orgánafluairín iad substaintí sár- agus polafhluarailcile (SSPFA) (Béarla: Per- and polyfluoroalkyl substances (PFAS nó 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.
