   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. LÄS MER

   Sammanfattning : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. LÄS MER

4. 8. Levels of brominated flame retardants in humans and their environment : occupational and home exposure

   Sammanfattning : Plasma from workers at an electronic dismantling plant were analysed for tri- to heptaBDEs (brominated diphenyl ethers), during 18 months. The different exposed groups showed concentrations ranging from 0.06to 2.8 ng g-1 (l. LÄS MER

5. 9. Aerosol Measurements as Applied for Exposure Characterization

   Författare :Andreas Dahl; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

   Sammanfattning : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. LÄS MER

7. 10. Essays on Corporate Exposure to Macroeconomic Risk

   Författare :Niclas Andrén; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inflation; interest rates; macroeconomic exposure; exchange rates; risk exposure; risk;

   Sammanfattning : Uncertainties in the macro economy are important sources of risk in today’s business world. Unexpected changes in exchange rates, interest rates, and inflation rates can lead to changes in corporate wealth and competitiveness and, in the extension, corporate market values – to what extent is the topic of this thesis.
