  1. 11. Exposure, health effects, immunological markers and biomarkers of susceptibility among Swedish rubber workers

    Författare :Lena S Jönsson; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yrkesmedicin; arbetsmiljömedicin; industrial medicine; Public health; epidemiology; Folkhälsa; epidemiologi; Occupational health; Andningsorganen; rubber industry; polymorphisms; vulcanisation fumes; Respiratory system; nausea; headache; exposure-response relationships; biomarkers; symptoms; airways; eyes; TTCA; PAH; 1-hydroxypyrene;

    Sammanfattning : Workers in the rubber industry have an increased risk of several diseases, such as airway disease, cancer and probably cardiovascular disease. The exposure is very complex; carbon disulfide (CS2) and polycyclic aromatic hydrocarbons (PAHs) being two of the contaminants. LÄS MER

  3. 12. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits

    Författare :Pernilla Bohlin; Göteborgs universitet; []
    Nyckelord :passive air sampling; PAH; POP; occupational environment; residential environment; exposure; stationary air sampling; personal air sampling; PUF; evaluation;

    Sammanfattning : Human exposure to elevated levels of polycyclic aromatic hydrocarbons (PAHs) and trace organic compounds (e.g. PCB, OCP, PBDE) can be related to negative health effects. This raises demands of exposure measurements to be performed. LÄS MER

  4. 13. Rapid sample preparation and bioanalytical techniques for efficient screening of organic pollutants in the environment

    Författare :Malin Nording; Peter Haglund; Ron Hoogenboom; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accelerated solvent extraction; CAFLUX; food; immunoassay; PAH; PCDD; PCDF; pressurized liquid extraction; soil; CALUX; cell-based bioassay; chemically activated fluorescent gene expression; chemically activated luciferase gene expression; dioxin; ELISA; enzyme-linked immunosorbent assay; feed; Environmental chemistry; Miljökemi;

    Sammanfattning : Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need for simpler techniques. The work underlying this thesis assessed the potential utility of more convenient sample preparation and bioanalytical techniques for rapidly screening various environmental matrices that could be useful complements to higher resolution methods.

  5. 14. Role of sediment organic matter quality and benthic organisms for the fate of organic contaminants in marine systems

    Författare :Maria E. Granberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sediment; ecotoxicology; macrofauna; bacteria; PAH; PCB;

    Sammanfattning : Marine sediments constitute important contaminant sources within our environment. Organic matter input to marine sediments changes seasonally in terms of both quantity and quality, and has been profoundly altered in many coastal areas due to eutrophication. LÄS MER

  7. 15. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation

    Författare :Thomas Metz; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pulsed lasers; Physics; Fysik; Laser technology; Laserteknik; non-linear spectroscopy; maximum likelihood; curve fitting; data adjustment; statistical inference; formaldehyde; PAH; polycyclic aromatic hydrocarbons; lifetime imaging; two-dimensional; streak camera; LIF; laser-induced fluorescence; Fluorescence lifetimes; time-resolved;

    Sammanfattning : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. LÄS MER
