  1. 1. Impact of PFAS exposure on the fecal metabolome

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Lisa Johansson; [2022]
    Keywords : Gut metabolites; LC-qTOF-MS; PFAS;

    Abstract : The human gut microbiota plays a crucial role in human health and therefore imbalances in gut microbiota functioning can lead to the development of metabolic disorders. Short-chain fatty acids (SCFA), tricarboxylic acid (TCA) cycle metabolites, bile acids (BA) and other metabolites are the essential compounds for the metabolome. READ MORE

    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

  4. 3. Mass flow and fate of per- and polyfluoroalkyl substances in a landfill in Uppsala, Sweden

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

    Author : Björn Bonnet; [2017]
    Keywords : PFASs; landfill; groundwater; sludge; STP; mass flow;

    Abstract : In this study, a landfill has been investigated in terms of the distribution of per- and polyfluoroalkyl substances and the environmental fate. 28 PFASs (13 PFCAs, 4 PFSAs, 3 FOSAs, 2 FOSEs, 3 FOSAAs and 3 FTSAs) have been analysed in 14 leachate, 11 groundwater and 9 sludge samples.

  5. 4. 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.

  6. 5. Analysis of Per- and Polyfluoroalkyl Substances (PFASs) in African Darter (Anhinga rufa) Eggs along Vaal River, South Africa : Comparison of Homologue and Isomer Profiles

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Felicia Fredriksson; [2016]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Perfluorooctane sulfonate PFOS ; linear and branched isomers; African Darter; Vaal River; bird eggs; Per- och polyfluoralkylerade substanser PFASs ; perfluoroktansulfonat PFOS ; linjära och grenade isomerer; African Darter; Vaal River; fågelägg;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of toxic and persistent organic compounds. Their properties make them extremely resistant and they have been shown to have bioaccumulation and toxic properties in the environment and also to biomagnify in both aquatic and terrestrial food webs.
