1. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method
Abstract : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.

2. Nanobubbles in water - how to identify them and why they are stable
Abstract : Gas bubbles smaller than 1 micrometer in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. READ MORE

3. The accessibility and chemical activity of polycyclic aromatic hydrocarbons in soil
Abstract : This thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. READ MORE

4. Study of arsenate adsorption on iron oxide by in situ ATR-FTIR spectroscopy
Abstract : Stabilization of arsenic contaminated soils by iron oxides has been proposed as a remediation technique to prevent leaching of arsenate into the environment. However, fundamental studies are needed to establish under which conditions the complexes formed are stable. READ MORE

5. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Abstract : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. READ MORE
