1. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

2. Occurrence of per- and polyfluorinated alkyl substances (PFAS), including ultra-short-chain compounds. Seasonal variation in rainwater from the Swedish west coast
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Per- and polyfluoroalkyl substances (PFAS) are a group of highly fluorinated compounds which comprises of more than 4700 substances. A smaller number of those substances is rou-tinely measured, usually the short (C4-C7) and long chain PFAS (>C7). READ MORE

3. A study to understand the information gap between total organofluorine analysis and total oxidizable precursor assay on polyfluoroalkyl/perfluoroalkyl substances (PFASs)
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Total oxidizable precursor (TOP) assay is an oxidation method to convert precursor compound of polyfluoroalkyl/perfluoroalkyl substances (PFASs) into measurable perfluorinated carboxylic acids (PFCAs). A previous mass balance study has shown that a loss of fluorine was observed after employing the method to convert the precursors in firefighting foams. READ MORE
