  1. 11. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Nora Larsson; [2022]
    Keywords : Per- and polyfluoroalkyl substances PFAS ; Food packaging materials; Extractable organofluorine; Method development; Combustion ion chromatography; Targeted analysis;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

  3. 12. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE

  4. 13. PFAS in a Swedish wastewater treatment plant : An analysis of the effectiveness of major treatment steps on 33 PFAS

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonatan Forsberg; [2022]
    Keywords : Northern Sweden; PFAS; municipal WWTP; MBBR; GAC;

    Abstract : Wastewater treatment plants (WWTP) are known spreaders of per- and polyfluoroalkyl substances (PFAS) into the environment. Luleå University of Technology is conducting a yearlong study in which PFAS concentrations in the different treatment steps are measured at Uddebo treatment plant. READ MORE

  5. 14. 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

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

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

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

    Abstract : 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. READ MORE
