    Abstract : 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. READ MORE

  3. 2. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Malin Bergman; [2017]
    Keywords : ;

    Abstract : 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. 3. Analysis of Per- and Polyfluorinated Substances (PFASs) in Eggs and Hen Food from Örebro County, Sweden

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Theolinda Hanell; [2015]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Effects of pH and Cation Composition on Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil Particles

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Malin Ullberg; [2015]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Soil; Partitioning coefficients; Partitioning; sorption; solution chemistry; electrostatic interaction; Visual MINTEQ; Perfluoroalkylsubstanser PFAS ; jord; partitioneringskoefficienter; sorption; lösningske- mi; elektrostatisk interaction; Visual MINTEQ;

    Abstract : 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. READ MORE

  6. 5. Bioaccumulation of poly- and perfluoroalkyl substances (PFASs) and mercury in European perch (Perca fluviatilis) : Spatial distribution and forest clear-cut (CC) effects in Swedish lakes

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Nesrin Negm; [2015]
    Keywords : PFAS; perfluoroalkyl substances; polyfluoroalkyl substances; European perch; forest clear-cut; bioaccumulation; lakes; mercury;

    Abstract : Recently poly- and perfluoroalkyl substances (PFASs) have gained increasing attention due to their ubiquitous distribution in the environment and adverse effects to human and wildlife. PFASs have unique chemical and physical properties such as surfactant characteristics and are used for many industrial applications (e.g. READ MORE
