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

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

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

    Sammanfattning : 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. LÄS MER

  2. 2. Do selected CF3-containing pharmaceuticals oxidize to trifluoroacetic acid (TFA)? – Analysis of ultra-short perfluoroalkyl acids (PFAAs) and their analytical challenges following oxidation

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Johanna Gillberg; [2022]
    Nyckelord :;

    Sammanfattning : Total oxidizable precursor assay (TOPA) has been used to understand the contribution of unknown precursors to the extractable organofluorine (EOF) compounds. The investigation of compounds containing a CF3 moiety especially connected to an aromatic ring is important because any compounds with such a moiety (pharmaceuticals) may oxidize to form trifluoroacetic acid (TFA).

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

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

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

    Sammanfattning : 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.

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

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Tilda Alvén Fimmerstad; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  5. 5. A Comparative Analysis of Per- andPolyfluoroalkyl Substances (PFAS) and ExtractableOrganofluorine (EOF) Using Solid PhaseExtraction-Weak Anion Exchange and Ion PairExtraction in SerumMarichal SalamehSpring 2021Independent project

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Marichal Salameh; [2021]
    Nyckelord :Extractable organofluorine EOF ; Per- and polyfluoroalkyl substances PFAS ; horse serum; human serum; ion pair extraction IPE ; solid phase extraction - weak anion exchange SPE-WAX ; liquid chromatography tandem mass spectrometry LC-MS MS ; combustion ion chromatography CIC ;

    Sammanfattning : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. LÄS MER
