1. Humanexponering för PFOS via konsumtion av egenfångad fisk från vattendrag runt Stockholm
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Sammanfattning : BAKGRUND: Per- och polyfluorerade alkylsubstanser, PFAS, är ett samlingsnamn för en stor grupp mycket stabila substanser. Vissa PFAS är klassade som persistenta, bioackumulerbara och toxiska (PBT-ämnen) och har en negativ hälsoeffekt på människor och djur. LÄS MER
2. An assessment of thermal desorption as a remediation technique for per- and polyfluoroalkyl substances (PFASs) in contaminated soil
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a diverse group of persistent organic pollutants. PFASs have a wide area of applications such as stain repellent for paper, textile, furniture and industrial products such as aqueous film forming foams (AFFFs) used for firefighting. LÄS MER
3. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.

4. Analysis of Per- and Polyfluorinated Substances (PFASs) in Eggs and Hen Food from Örebro County, Sweden
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Perfluorinated alkyl substances (PFASs) have been used for various purposes for decades and have shown to have toxic properties. The main source of human exposure seems to be through the dietary where eggs, fish, meat and dairy products are the main sources. LÄS MER
5. Effects of pH and Cation Composition on Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil Particles
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Per- and polyfluoroalkyl substances (PFASs) have drawn great attention recently, due to their environmental persistence, potential toxicity and global distribution. PFAS is a large family of substances, characterized by a perflourinated carbon chain and a functional group. LÄS MER
