   Abstract : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. READ MORE

3. 2. Method development of total oxidizable precursor assay for perfluoroalkyl acid precursors in domestic sludge

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Lydia Söderlund; [2018]
   Keywords : Total oxidizable precursor assay TOP assay ; Perfluoroalkyl substances PFASs ; Perfluoroalkyl acids PFAAs ; Sewage sludge; Oxidative conversion; Organofluorine;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are persistent organic pollutants used in industrial applications and are globally distributed in the environment. A group of PFASs that are difficult to measure with today’s method are perfluoroalkyl acid precursors (PFAA precursors) that, when degraded, serves as indirect sources of PFAAs. READ MORE
