  1. 1. Human Exposure to Per- and Polyfluoroalkyl : Substances through Fish Consumption

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Welmoed Nauta; [2023]
    Keywords : Per- and polyfluoroalkyl substances; Human exposure; Fish consumption; Glasbruket; Target analysis; Mass balance analysis;

    Abstract : Human exposure to per- and poly-fluoroalkyl substances (PFAS) occurs mainly through two pathways, inhalation and ingestion. Dietary exposure to persistent organic pollutants (POPs), including PFAS, is driven mainly by the consumption of foods of marine or terrestrial animal origin. READ MORE

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

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Tilda Alvén Fimmerstad; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Sofia Francois; [2021]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. READ MORE

  5. 4. Total oxidizable precursor assay: Applications and limitations. A study on the occurrence of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in Chinese Wastewater Treatment Plants

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Pontus Larsson; [2020]
    Keywords : ;

    Abstract : Total oxidizable precursor (TOP) assay is an in-lab method which oxidatively converts precursor compounds of poly- and perfluoroalkyl substances (PFASs) into measurable perfluorinated alkyl acids (PFAAs). The method is a very strong tool to semi-quantify PFASs that would otherwise be missed in conventional targeted analysis using liquid chromatography - tandem mass spectrometry (LC-MS/MS). READ MORE

  6. 5. The study of organofluorine analysis applied to totaloxidizable precursor (TOP) assay to understand perandpolyfluoroalkyl substances (PFASs)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Crystal Ho; [2018]
    Keywords : Poly- per-fluoroalkyl substances; total oxidizable precursor TOP assay; AFFFs; combustion ion chromatography; oxidation;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals which are used in a wide range of applications such as aqueous film forming foam (AFFF) for firefighting, paint, coating and cosmetics. For almost a decade, PFASs have received worldwide attention because of the ubiquitous detection of PFAS in the environment and their bioaccumulative, persistent and give toxic effects on animals and humans.
