  1. 1. Known and unknown bioaccumulating per- and polyfluoroalkyl substances in pilot whales

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

    Författare :Victor Andréasson; [2020]
    Nyckelord :;

    Sammanfattning : Per- and- polyfluoroalkyl substances (PFASs) are widely used in commercial and industrial products and leach into the environment from different applications. PFASs poses an issue to both wildlife and humans because of different toxic properties. LÄS MER

  3. 2. Perfluorooctane sulfonate (PFOS) and related chemicals in eggs from Sweden and China

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

    Författare :Yasmin Karimi; [2019]
    Nyckelord :PFOS; PFOA; Chicken Egg; LC-MS MS; Organic egg; Conventional egg;

    Sammanfattning : Dietary intake is one of the major routes of human exposure to perfluoroalkyl and/or polyfluoroalkyl substances (PFAS). The objective of this study was to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) in organic and conventional egg from Sweden (n=8, consisted of 4 pooled eggs and 4 individuals) and China (n=9, consisted of 4 pooled eggs and 5 individuals) and compare the concentrations of PFAS between the two categories (organic and conventional).

  4. 3. Global Priority Perfluoroalkyl Substances in Surface Waters:Establishing Baseline Levels on Regional Basis.

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

    Författare :Abeer Baabish; [2019]
    Nyckelord :;

    Sammanfattning : Perfluorooctane sulfonic acid (PFOS) has been regulated under Stockholm Convention in 2009, perfluorooctanoic acid (PFOA) was listed in 2019. Perfluorohexane sulfonic acid (PFHxS) is under review and could be included in 2021. LÄS MER

  7. 5. Effect of PFOS and HBCD on the lipid profiles of developing rainbow trout (Onchorhynchus mykiss) analyzed with UHPLC/Q-TOF-MS

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

    Författare :Vanja Stefanovic; [2018]
    Nyckelord :Perfluorooctane sulfonate; hexabromocyclododecane; lipid metabolism; UHPLC Q-TOF-MS;

    Sammanfattning : Perfluorooctane sulfonate (PFOS) is widely used in industrial products and is potentially dangerous to the aquatic environment due to not being broken down whether by chemical or biological means, having a half-life of more than 41 years and disrupting hormones. Hexabromocyclododecane (HBCD) is the third most used brominated flame retardant and is of environmental concern as it bioaccumulates and magnifies in the food chain and is highly toxic to aquatic organisms.
