1. 1. Is two stage GAC better than one stage GAC for removing PFAS at a DWTP? : Investigation of PFAS removal from drinking water using two stage granular activated carbon (GAC) filter

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Oliver Ekesiöö; [2023]
   Nyckelord :GAC; PFAS; drinking water treatment; two stage GAC;

   Sammanfattning : The removal of 34 per- and polyfluoroalkyl substances (PFAS) were compared in a 1 stagegranular activated carbon (GAC) filtration to a 2 stage GAC filtration in a pilot study at adrinking water treatment plant (DWTP). The PFASs that were present in the water wereperfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluoropentanoic acid(PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), perfluorobutanesulfonic acid (PFBS), perfluoropentane sulfonic acid (PFPeS) and perfluorohexane sulfonic acid(PFHxS).

3. 2. Sorption of per- and polyfluoroalkyl substances (PFAS) in contaminated water using sustainable organic- and inorganic materials

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Natalie Storm; [2022]
   Nyckelord :Sorption | PFAS | Contaminated water | Bark | Steel slag | Biochar | Activated carbon;

   Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic compounds with unique properties, including chemical inertness, resistance to many degradation processes and amphiphilic structure. This makes them useful in a range of applications, but also very persistent and bioaccumulative in nature, where PFAS have been linked to adverse health effects in both animals and humans. LÄS MER

4. 3. Could fluorinated pharmaceuticals have an impact on the EOF amount in human blood?

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Tilda Alvén Fimmerstad; [2022]
   Nyckelord :;

   Sammanfattning : Recent studies have discovered an increasing amount of unknown organofluorine in human blood. This increase insinuate that humans might be exposed to potentially new and unidentified organofluorine compounds. LÄS MER

5. 4. Per- and polyfluoroalkyl substances (PFAS) and the effect on apoptosis in early porcine embryo development in vitro

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

   Författare :Anna Leclercq; [2021]
   Nyckelord :apoptosis; PFAS; PFOS; PFHxS; IVF; IVP; porcine; pig; embryo; TUNEL; reproduction;

   Sammanfattning : The aim of this study was to evaluate the effects of PFHxS (perfluorohexane sulfonic acid) and PFOS (perfluorooctane sulfonic acid) on early embryo development parameters and apoptosis on day 6 post fertilization in porcine embryos. A second purpose was to evaluate, and establish, the TUNEL assay in our IVF laboratory. LÄS MER

7. 5. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

   Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Pascal Camoiras González; [2019]
   Nyckelord :;

   Sammanfattning : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).
