  2. 1. Physical properties and processes of secondary organic aerosol and its constituents

    Author : Kent Salo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

    Abstract : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. READ MORE

  4. 2. Formation, ageing and thermal properties of secondary organic aerosol

    Author : Eva U. Emanuelsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volatile organic compounds; biogenic; anthropogenic; secondary organic aerosol; troposphere; volatility; ozone;

    Abstract : In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes and properties of atmospherically relevant secondary organic aerosol (SOA) from both biogenic and anthropogenic origin.

  5. 3. Characterization of Aerosols Related to Occupational and Public Environments as Applied to Isocyanates and Road Wear

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The aim of this thesis was to characterize a personal denuder/filter sampler for isocyanate aerosol and to study the emission of airborne particles from the interaction between studded tires and pavements. Both types of aerosols are highly relevant for health studies in public and occupational environments. READ MORE

  6. 4. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols

    Author : Åsa M. Jonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tropospheric chemistry; monoterpenes; ozonolysis; secondary organic aerosol SOA ; G-FROST; AIDA; humidity; temperature; hydroxyl radicals; volatility; pinonaldehyde; climate and health;

    Abstract : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. READ MORE
