    Sammanfattning : Air pollution with particulate matter (PM) raises considerable concern because of its adverse effects on human health. For this reason, and because the mechanisms of PM toxicity are not fully known, there is an urgent need to determine the chemical constituents of atmospheric PM, especially PM emanating from traffic - a major source of urban PM.

  3. 3. Determination of Polycyclic Aromatic Hydrocarbons in Various Environmental Matrices : Emphasis on extraction method development

    Detta är en avhandling från Stockholm : Department of Analytical Chemistry, Stockholm University

    Författare :Silvia Masala; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Very recently, air pollution was declared the world’s single largest environmental health risk by the World Health Organization. The goal of this thesis is to contribute to a better assessment of air pollution through the development of novel and exhaustive extraction methods for the analysis of polycyclic aromatic hydrocarbons (PAHs), which are mutagenic and carcinogenic air pollutants.

  4. 4. Traffic related air pollution with emphasis on particle associated polycyclic aromatic hydrocarbons Tire wear and biodiesel exhaust emissions

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Ioannis Sadiktsis; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is regarded as one of the more important components of air pollution causing adverse health effects. A large group of compounds associated with PM are polycyclic aromatic compounds (PACs) which comprises polycyclic aromatic hydrocarbons (PAHs). LÄS MER
