1. Road traffic metals : sources and emissions
Abstract : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. READ MORE

2. Traffic Emissions of Aerosols
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

3. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model
Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE

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