  1. 21. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Författare :Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. LÄS MER

  4. 23. 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

  5. 24. Some biotic and abiotic aspects of the environmental chemistry of PAHs (polycyclic aromatic hydrocarbons) and PCDD/Fs (polycychlorinated dibenzodioxins and dibenzofurans)

  7. 25. Properties of some chlorinated polycyclic aromatic hydrocarbons with respect to chemical analysis

    Författare :Ulrika Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes chemical and biological properties of chloro-added and chloro-substituted PAHs with respect to chemical analysis. The work includes biological testing with Ames assay, study of chemical reactivities in chlorination reactions and retention characteristics on normal phase stationary phases for HPLC, as well as analysis of urban air samples with respect to chlorinated PAHs (Cl-PAHs).
