7. Towards Prospective Exposure Modeling of Nanoparticles - Applying Particle Flow Analysis and Kinetic Exposure Modeling for the Cases of TiO2 and Ag Nanoparticles
Abstract : The claims regarding the usefulness of nanoparticles (NPs) in different applications, such as wound dressings, solar cells and soil remediation, has been accompanied by concern that NPs may also pose risks to humans and to the environment. Considering the past century, when many substances later shown to cause unacceptable damage were manufactured in large amounts, there are reasons to thoroughly assess the risks of these NPs.

10. 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
