    Abstract : All hydrocarbons emitted from production and use of petrol are hazardous to human health and the environment, but to a different extent for individual compounds. This thesis compares and characterizes C2-C8 hydrocarbons related to alkylate petrol and conventional petrol. READ MORE

  5. 3. Exposure to motor exhaust in the occupational and general environment in Stockholm county

    Author : Marie Lewné; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Exposure measurement; NO2; Particles; EC; diesel exhaust;

    Abstract : In recent years, health hazards associated with air pollution from motor exhaust have received increasing attention. Lung cancer and heart disease have been linked to air pollution exposure. However, the knowledge concerning exposure levels, is insufficient, but is essential for risk assessment. READ MORE

    Abstract : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. READ MORE
