Abstract

The present study tested some aqueous film-forming foam (AFFF) products for the presence of or the potential to form 1H,1H,2H,2H-perfluorooctanesulfonic acid (6:2FTS) and 1H,1H,2H,2H-perfluorodecane sulfonic acid (8:2FTS). The results demonstrated the appearance of significant levels of 6:2FTS and 8:2FTS after the oxidization of those AFFFs. The authors concluded that fluorotelomer skeletons exist but are derived from those formulations of AFFFs.

Keywords: AFFF; Fluorosurfactants; Oxidization; Perfluorotelomer.
