1. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies
Abstract : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. READ MORE

2. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment
Abstract : 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.

3. Contribution of stormwater ponds for road runoff to aquatic biodiversity
Abstract : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. READ MORE

4. Road construction materials as a source of pollutants
Abstract : This thesis deals mainly with road construction materials, particularly in cases where they may contribute polluting substances. The complexity of the measuring and evaluation of some pollutants with respect to sampling and chemical analysis is considered. READ MORE

5. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements
Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE
