Populærvitenskapelig sammendrag av avhandlingen:
Every day, we are exposed to chemicals through air, food, water and products we use. In partircular, PFAS (a group of >4700 organofluorine chemicals) are found in objects that we use eveyday (for example outdoor clothing) and have received international attention due to their presence in human blood worldwide and potential health effects. In this thesis we used different methods on human blood collected in the Tromsø Study to investigate how exposure to PFAS and other organofluorine chemicals in the Tromsø population has been changing between 1986-2015. The results show that in recent years the total organofluorine found in blood did not increase and PFAS concentrations have been declining (even if some individual PFAS are increasing). For the first time we measured PFAS precursors (chemicals that can be transformed to PFAS in our body) and found that they contributed little to organofluorine exposure. We also found that a significant part of the organofluorine in blood was explained by the presence of organofluorine pharmaceuticals. Lastly, part of the organofluorine in blood could not be described but this unidentified portion decreased between 1986-2015.
