  1. 1. Immunohepatotoxicity of the persistent environmental pollutants perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS)

    Författare :Mousumi Rahman Qazi; Joe DePierre; Christopher Lau; Stockholms universitet; []
    Nyckelord :Perfluorooctanoate; Perfluorooctane sulfonate; Peroxisome proliferator-activated receptor-alpha; Hepatomegaly; Immunotoxicity; Thymus; Spleen; Biochemistry; biokemi;

    Sammanfattning : Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), manufactured for a variety of industrial and consumer applications, are ubiquitous environmental pollutants. Their accumulation in humans and wildlife raises serious health concerns. Here, we examined the potential effects of PFOA and PFOS on the innate immune system in mice. LÄS MER

    Sammanfattning : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. LÄS MER

  5. 4. 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. 5. 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.
