  1. 6. Analysis and human levels of persistent perfluorinated chemicals

    Författare :Anna Kärrman; Gunilla Lindström; Bert van Bavel; Ulf Järnberg; Jessika Hagberg; Lennart Hardell; Derek Muir; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. LÄS MER

  3. 7. Modeling the global fate and transport of perfluoroalkylated substances (PFAS)

    Författare :James M. Armitage; Ian T. Cousins; Michael S. McLachlan; David Ellis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perfluoroalkylated substances; global-scale; fate and transport; Environmental chemistry; Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluoroalkylated substances (PFAS) are persistent contaminants that are widely distributed in the global environment. Despite the fact that these chemicals have been manufactured and used for over 50 years, there has been little scientific and regulatory interest until very recently. LÄS MER

  4. 8. Assessing environmental and contaminant stressors in a benthic amphipod

    Författare :Therese Jacobson; Brita Sundelin; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple stressors; Reproduction; Temperature; Food; Parasites; Fenarimol; PFOS; TBT; Endocrine disruption; Ecdysteroids; Microsporidia; Microcosm; Crustacea; Amhipoda; Monoporeia affinis; Biology; Biologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organisms in the aquatic environment encounter numerous stressors throughout their lifespan. Some of them are biotic such as food availability, predators and parasites. Others are abiotic and include shifting salinity and temperature change among others. LÄS MER

  5. 9. Fluorine mass balance in wildlife and consumer products : How much organofluorine are we missing?

    Författare :Lara Schultes; Jonathan P. Benskin; Michael McLachlan; Jörg Feldmann; Elsie M. Sunderland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFASs; PFOS; fluorine mass balance; organofluorine; EOF; TF; wildlife; consumer products; combustion ion chromatography; high resolution mass spectrometry; suspect screening; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a class of anthropogenic pollutants. Many PFASs are highly persistent and have been linked to adverse effects in humans. According to latest estimates, there are more than 4700 PFASs in global commerce, which poses immense challenges for environmental monitoring. LÄS MER

  7. 10. Tissue distribution studies and risk assessment of perfluoroalkylated and polyfluoroalkylated substances (PFASs)

    Författare :Daniel Borg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Perfluoroalkylated and polyfluoroalkylated substances (PFASs) represent a large class of man-made chemicals. These substances have emerged as environmental contaminants due to their extraordinary resistance to degradation, potential for bioaccumulation, toxicity and a global presence in humans, wildlife and the environment.
