1. Human Exposure to Per- and Polyfluoroalkyl : Substances through Fish Consumption
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Human exposure to per- and poly-fluoroalkyl substances (PFAS) occurs mainly through two pathways, inhalation and ingestion. Dietary exposure to persistent organic pollutants (POPs), including PFAS, is driven mainly by the consumption of foods of marine or terrestrial animal origin. LÄS MER
2. Could fluorinated pharmaceuticals have an impact on the EOF amount in human blood?
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Recent studies have discovered an increasing amount of unknown organofluorine in human blood. This increase insinuate that humans might be exposed to potentially new and unidentified organofluorine compounds. LÄS MER
3. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances
Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. LÄS MER
4. Total oxidizable precursor assay: Applications and limitations. A study on the occurrence of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in Chinese Wastewater Treatment Plants
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Total oxidizable precursor (TOP) assay is an in-lab method which oxidatively converts precursor compounds of poly- and perfluoroalkyl substances (PFASs) into measurable perfluorinated alkyl acids (PFAAs). The method is a very strong tool to semi-quantify PFASs that would otherwise be missed in conventional targeted analysis using liquid chromatography - tandem mass spectrometry (LC-MS/MS). LÄS MER
5. The study of organofluorine analysis applied to totaloxidizable precursor (TOP) assay to understand perandpolyfluoroalkyl substances (PFASs)
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals which are used in a wide range of applications such as aqueous film forming foam (AFFF) for firefighting, paint, coating and cosmetics. For almost a decade, PFASs have received worldwide attention because of the ubiquitous detection of PFAS in the environment and their bioaccumulative, persistent and give toxic effects on animals and humans.
