  1. 1. Occupational exposure to fluorinated ski wax

    Författare :Helena Nilsson; Jonathan W. Martin; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated; polyfluorinated; FIS; occupational exposure; ski wax; biotransformation; metabolism; fluorotelomer alcohol; fluorotelomer acid; aerosol; dust; UPLC MS-MS; GC MS-MS; Kemi; Chemistry;

    Sammanfattning : Per- and polyfluorinated substances (PFAS) are used in the production of ski wax to reduce the friction between the snow and the ski. In this occupational study of ski wax technicians’ exposure to PFAS and particulate aerosol we have collected whole blood (wb) (n =94), air (n =84) and aerosol (n =159) samples at World Cup events from 2007-2011.

  3. 2. Assessment of human exposure to per- and polyfluorinated compounds (PFCs) : exposure through food, drinking water, house dust and indoor air

    Författare :Ingrid Ericson Jogsten; Gunilla Lindström; Bert van Bavel; Stuart Harrad; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human exposure; per- and polyfluorinated compunds PFCs ; dietary intake; drinking water; indoor environment; TECHNOLOGY; TEKNIKVETENSKAP; Environmental chemistry; Miljökemi; Chemistry; Kemi; Miljökemi; Environmental Chemistry; Kemi; Chemistry;

    Sammanfattning : Per- and polyfluorinated compounds (PFCs) are detected in humans worldwide but all sources of human exposure have not been fully characterized. The aim of this thesis was to evaluate the contributions from food, water, air and dust as sources for human PFC exposure in the general population. LÄS MER

  5. 4. Samarium(II)-mediated Reactions in Organic Synthesis - Method Development and Mechanistic Investigation

    Författare :Tobias Ankner; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Samarium II iodide; reduction; single electron transfer; nitro group reduction; mechanistic study; bond cleavage; deoxygenation; additives; toluenesulfonyl deprotection; defluorination.;

    Sammanfattning : This thesis describes the development of methods using divalent samarium reagents in organic synthesis. The main focus is placed on functional group reductions, but reductive formation of carbon-carbon bonds has also been investigated. LÄS MER

  7. 5. Exposure to perfluorinated alkyl substances and health effects in pregnant women and their children

    Författare :Matilda Ebel; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfluorinated alkyl substances; epidemiology; prenatal exposure; maternal health; child health; register studies;

    Sammanfattning : Per- and polyfluorinated alkyl substances (PFAS) are chemicals that have gained attention during the last years. There are about 10,000 different PFAS compounds, and due to their unique chemical characteristics, PFAS has been used in a variety of industrial applications and household products since the 1950s.
