  1. 1. Analysis of fluoroalkyl sulfonamide (FASA) based copolymers : An indirect source of non-polymeric PFAS

    Författare :Felicia Fredriksson; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Robert Letcher; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PFAS; FASA-based copolymers; fluorine mass balance; EOF; sludge; TF; earthworm; exposure;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are an extensive group of anthropogenic compounds and are of global concern due to their negative effects on the environment and humans. Most environmental research reports non-polymeric PFAS, leading to a scarce understanding of polymeric PFAS, despite their large share on the global market. LÄS MER

  3. 2. PFAS in the water supply: source water contamination

    Författare :Dauren Mussabek; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; source water; drinking water; per- and polyfluoroalkyl substances; PFAS; AFFF; UV treatment;

    Sammanfattning : Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. LÄS MER

  4. 3. Influence of gut microbiota on xenobiotic toxicity in a Caenorhabditis elegans model with a focus on arsenic and PFAS

    Författare :Jagadish Mangu; Jana Jass; Abul Mandal; Nektarios Tavernarakis; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; physiological responses; gut microbe models; arse-nite; arsenate; PFAS; PFOS;

    Sammanfattning : Exposure to environmental toxins presents a hazard to humans. Inorganic metalloid- arsenic (As), organic chemicals- per and poly-fluoroalkyl substances (PFAS) are frequently detected in the environment. Exposure to As and PFAS is associated with multiple adverse effects in humans and animals. LÄS MER

  5. 4. Remediation of per- and polyfluoroalkyl substance-contaminated soil and groundwater, using electrokinetic and stabilisation methods

    Författare :Georgios Niarchos; Fritjof Fagerlund; Anett Georgi; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PFAS; contamination; emerging contaminants; forever chemicals; pollution; soil; groundwater; remediation; electrokinetic; stabilisation; activated carbon;

    Sammanfattning : Per- and polyfluoroalkyl substances, commonly known as PFAS, are emerging contaminants with a worldwide environmental distribution and a concerning (eco)toxicological profile. The omnipresence of PFAS in various environmental media poses risks to the quality of our drinking water sources. LÄS MER

  7. 5. Analysis of Perfluoroalkyl Acids in Swedish Biota : Temporal trends, tissue distribution and toxicity

    Författare :Katrin Holmström; Urs Berger; Gregg Tomy; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PFOS; PFAS; pollutant; Baltic guillemot; peregrine falcon; Monoporeia affinis; time trend; toxicity; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. LÄS MER
