  2. 1. Traffic Emissions of Aerosols

    Author : Matthias Vogt; Douglas Nilsson; Eiko Nemitz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. READ MORE

  4. 2. Studies of aerosol particle formation from various sources using ion and electron beam analytical techniques

    Author : Arash Gharibi; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GUPIX; TEM; SEM; EDX; biomass combustion; traffic; road; jet droplets; film droplets; Physics; Nuclear physics; Fysik; Kärnfysik; pollution control; Environmental technology; Aerosol particles; PIXE; sources emission; tire; Arctic; Miljöteknik; kontroll av utsläpp; Fysicumarkivet A:000;

    Abstract : The thesis presents the results of studies of aerosol particle formation using ion and electron beam analytical techniques. The sources of aerosol particle formation studied are the following: 1. production of primary aerosol particles in the high Arctic region during summers 2. READ MORE

  5. 3. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships

    Author : Jörg Beecken; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollution; compliance monitoring; shipping; ship emission; particle emissions; identification of polluting ships; emission factors;

    Abstract : Shipping significantly contributes to the world's anthropogenic emissions of sulfur, nitrogen species and particulate matter. These species affect the global radiative forcing as well as local acidification, eutrophication and human health. READ MORE

  6. 4. Nanoparticles from shipping and road traffic

    Author : Olof Jonathan Westerlund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Aerosols; Size distributions; Emissions; Plume processes; Shipping; Road traffic;

    Abstract : In the urban environment road traffic is the dominant source of aerosol particles while in coastal and harbour areas shipping is also a significant source. For shipping there are no direct regulations regarding particle emissions. READ MORE

  7. 5. Emission estimation based on traffic models and measurements

    Author : Nikolaos Tsanakas; Jan T. Lundgren; Joakim Ekström; Johan Olstam; Marcus Gerstenberger; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Traffic congestion increases travel times, but also results in higher energy usage and vehicular emissions. To evaluate the impact of traffic emissions on environment and human health, the accurate estimation of their rates and location is required. READ MORE
