  2. 1. Methods for measurement of reactive metabolites as a basis for cancer risk assessment : Application to 1,3-butadiene and isoprene

    Author : Charlotta Fred; Margareta Törnqvist; Peter Farmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Abstract : 1,3-Butadiene is a general air pollutant associated with combustion of organic matter and is also an extensively used monomer in polymer production. The cancer risk estimation of 1,3-butadiene is encumbered with large uncertainties. READ MORE

  4. 2. Exposure to some carcinogenic compounds in air, with special reference to wood smoke

    Author : Pernilla Gustafson; Göteborgs universitet; []
    Keywords : formaldehyde; acetaldehyde; 1; 3-butadiene; benzene; polycyclic aromatic hydrocarbons; particulate matter; domestic wood burning; exposure assessment; personal exposure; experimental study;

    Abstract : The general population is exposed to air pollutants in both indoor and outdoor air from many different sources, including traffic, biomass burning, industries, cigarette smoking, and certain building materials. Air pollutants can cause a variety of health effects such as cancer and respiratory and cardiovascular diseases. READ MORE

  5. 3. Volatile Hydrocarbons in Ambient Air. Gas Chromatographic Assessment, Emissions and Human Exposure

    Author : Gunnar Barrefors; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adsorbent sampling; 1; gas chromatography; biomass burning; Benzene; ethene; vehicle emissions; urban air; tobacco smoke; 3-butadiene;

    Abstract : Hydrocarbons in ambient air constitute a potential health risk for a large number of individuals. The work reported in this thesis focusses on human exposure to volatile hydrocarbons in ambient air. The analytical determinations were made by adsorbent sampling followed by thermal desorption and gas chromatography. READ MORE

  6. 4. Alkylate Petrol. Environmental Aspects of Volatile Hydrocarbon Emissions

    Author : Ulf Östermark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrocarbons; small engines; alkylate; alkenes; ethene; benzene; 3-butadiene; two-stroke engines; reformulated petrol; reformulated gasoline; 1;

    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
