  1. 6. Investigation of unknown groundwater flows to two leachate ponds at Hovgården

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Katja Nordström; [2023]
    Nyckelord :landfill; leachate; principle component analysis; PCA; polishing pond;

    Sammanfattning : The leaching of groundwater into two polishing ponds, the last step in the wastewater treatment process on Hovgarden waste facility, was examined. The focus of this study was to analyse the PFAS composition profile (fingerprint) to trace the leaching groundwater. LÄS MER

  3. 7. Assessing the thyroid gland impairing effects associated to GenX exposure : A literature study

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Julia Mauritzon; [2023]
    Nyckelord :PFAS; GenX; HFPO-DA; Thyroid gland; PFAS; GenX; HFPO-DA; Sköldkörteln;

    Sammanfattning : GenX, a newly synthesized per- and polyfluoroalkyl substance (PFAS), has gained attention as a supposedly safer replacement for the long-chain PFAS, PFOA. Given the thyroid gland being known to be a target organ for the health effects of PFOA, it is crucial to investigate GenX potential impact on the thyroid gland. LÄS MER

  4. 8. 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

  5. 9. EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Lieke van Iersel; [2022-08-08]
    Nyckelord :oxygen consumption; zebrafish larvae; respirometry; endocrine disrupting chemicals; mixture toxicity;

    Sammanfattning : Chemicals affecting the endocrine system, so called endocrine disrupting chemicals (EDC’s), have been steadily increasing in the environment over the last 40 years. EDCs are harmful chemicals since they can act through multiple endocrine pathways, contain a wide spectrum of health effects that can be very persistent and can cause effects already at a low doses.

  7. 10. Does in vivo exposure to perfluorooctanesulfonicacid induce an altered colonic barrier function inmice?

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Hanna-Dalia Laar; [2022]
    Nyckelord :PFOA; PFAS; Ulcerative colitis; colon barrier; gastrointestinal permeability; Ussing Chamber;

    Sammanfattning : Background: Several environmental risk factors have been implicated in the pathogenesis ofinflammatory bowel disease (IBD) and might cause an altered barrier function, a hallmark ofIBD. Recent evidence suggests that patients with late-onset ulcerative colitis (UC) have anincreased serum level of perfluoroalkyl substances (PFAS), one of the major chemical groupscontaminating our diet.
