Analysis of PFASs and TOF in products


Per- and polyfluorinated substances (PFASs) are a large group of substances used in industrial and consumer applications. There are thousands of PFASs on the global market, for many of which there is little information on their use. This study is a follow-up of a NORAP project from 2015 where different household products were analysed for PFASs. Here we further analysed these products for total organic fluorine (TOF) together with new analyses for individual PFASs and TOF in product types that are known to or suspected to contain PFASs. The analyses of new products showed that PFASs are widely used. The comparisons between analysed individual PFASs and TOF concentrations showed that for most samples the detected individual PFAS constituted only a very minor part of the TOF, illustrating large data gaps in our knowledge on which PFASs that are being used in these products.
