  1. 36. Radiofrequency fields : exposure, dose and health

    Författare :Jonna Wilén; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic fields; SAR; Specific Absorption; subjective symptoms;

    Sammanfattning : The overall aim of this thesis is to increase our knowledge of relevant exposure parameters when discussing possible health implication from exposure to radiofrequency electromagnetic fields (RF), especially effects that might occur at non-thermal levels.In this thesis an effort is made to broaden the exposure assessment and to take the exposure time into account and combine it with the Specific Absorption Rate (SAR) and the field parameters (electric and magnetic field strength) to approach a dose concept.

  4. 38. Environmentally relevant chemical disruptors of oxidative phosphorylation in Baltic Sea biota : Exposure and toxic potentials

    Författare :Anna-Karin Dahlberg; Lillemor Asplund; Åke Bergman; Göran Marsh; Patrik Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxidative phosphorylation; OH-PBDEs; MeO-PBDEs; PBDEs; long-tailed duck Clangula hyemalis ; Baltic herring Clupea harengus ; Baltic blue mussel Mytilus trossulus x Mytilus edulis ; Baltic Sea; miljökemi; Environmental Chemistry;

    Sammanfattning : This thesis focuses on toxicity and occurrence of hydroxylated polybrominated diphenyl ethers (OH-PBDEs) in Baltic Sea biota. The aims were to assess OH-PBDEs potency for disruption of oxidative phosphorylation (OXPHOS) and determine their and related compounds exposure in Baltic blue mussel, herring and long-tailed duck.

  7. 40. Biomarkers of exposure to pesticides in humans

    Författare :Eva Ekman; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :Biomarker; Mass Spectrometry; Pharmacokinetics; Exposure assessment; Peticides; Pregnant Women; Biomonitoring; Urine; LC-MS MS; Biomarker; Mass Spectrometry; Pharmacokinetics; Exposure assessment; Peticides; Pregnant Women; Biomonitoring; Urine; LC-MS MS;

    Sammanfattning : Almost every human is exposed to pesticides, in work environments, by domestic use and via diet, drinking water and personal products. Current research expresses concern that low dose exposure over time can lead to adverse health effects. LÄS MER
