Peruorinated compounds (PFCs) are synthetic organic chemicals used in a variety of industrial
and commercial applications, including surfactants in pesticides, surface protectors in textiles, furnishings, and food packaging. PFCs become emerging chemicals of concern and two of them,
namely peruorooctane sulfonate (PFOS) and peruorooctane sulfonyl uoride (POSF) were listed
as “restricted use” (Annex B) under the Stockholm Convention in May 2009. PFCs have an anionic
functional group and nonpolar peruoroalkyl chain. This moiety allows them to repel both water26.1 Introduction ... 593
