1. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles
Sammanfattning : Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this th.. LÄS MER
2. Traffic related air pollution with emphasis on particle associated polycyclic aromatic hydrocarbons : Tire wear and biodiesel exhaust emissions
Sammanfattning : Particulate matter (PM) is regarded as one of the more important components of air pollution causing adverse health effects. A large group of compounds associated with PM are polycyclic aromatic compounds (PACs) which comprises polycyclic aromatic hydrocarbons (PAHs). LÄS MER
3. Studies of aerosol particle formation from various sources using ion and electron beam analytical techniques
Sammanfattning : 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. LÄS MER
4. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment
Sammanfattning : The prevalence of microplastic contamination has raised concerns about the potential risk and impact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP), polymer-modified bitumen, and road markings contribute to the emissions, and TWP are assumed to be one of the largest sources of microplastic emissions.

5. Characterization of Aerosols Related to Occupational and Public Environments as Applied to Isocyanates and Road Wear
Sammanfattning : 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. LÄS MER
