1. Characterisation of PFASs and Organofluorine in Freshwater Environments : Transfer from water to land via emergent aquatic insects
Abstract : Per- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern, because many are highly persistent to degradation and have been linked to adverse effects in humans as well as their ubiquitous spread in aquatic environments. This thesis investigated distribution of PFASs and organofluorine in freshwater environments impacted by PFAS point sources. READ MORE

2. Fluorine mass balance in wildlife and consumer products : How much organofluorine are we missing?
Abstract : Per- and polyfluoroalkyl substances (PFASs) are a class of anthropogenic pollutants. Many PFASs are highly persistent and have been linked to adverse effects in humans. According to latest estimates, there are more than 4700 PFASs in global commerce, which poses immense challenges for environmental monitoring. READ MORE

3. Ultra-short-chain perfluoroalkyl acids : Environmental occurrence, sources and distribution
Abstract : Ultra-short-chain perfluoroalkyl acids (PFAAs) is a group of highly fluorinated and very stable chemicals. Their small molecular structure in combination with the acidic functional group result in highly polar compounds and concern has been raised as these substances may threaten our drinking water supplies.

4. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure
Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE

5. Stabilization remediation of soils contaminated with per- and polyfluoroalkyl substances (PFASs)
Abstract : Per- and polyfluoroalkyl substances (PFASs) are a major global concern in pollution of drinking water sources and aquatic environments. Due to the high persistence and mobility of these compounds, remediation methods for PFAS-contaminated soils are urgently needed to protect the surrounding environment and drinking water source areas.
