  1. 1. Removal of PFASs and Uranium from Drinking Water Using SorbixTM Anion Exchange Resin : Effects of Sodium Chloride on the Removal Efficiency

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Fawaz Rustum; [2021]
    Keywords : Perfluorinated; polyflourinated; adsorption; fluorotelomer; salt; perfluorerade; polyfluorerade; adsorption; fluorotelomer; salt;

    Abstract : The increasing awareness towards PFAS pollution makes it increasingly important to treat. Many agencies over the globe, including the Swedish Food Agency, are introducing ever so strict control over PFASs in drinking water. READ MORE

  3. 2. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Sofia Francois; [2021]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

    Abstract : 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. READ MORE

  4. 3. Groundwater Flow and Transport Modelling of PFASs in Åkersberga

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Worada Boonraksasat; [2019]
    Keywords : Groundwater modelling; contaminant transport; Visual MODFLOW; MODPATH; MT3DMS; PFASs; AFFFs;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of man-made organic chemicals that have been commercially used since the 1950s in many consumer products, including impregnated textiles, impregnated paper, nonstick products (e.g., Teflon), cleaning agents, and in firefighting foams.

  5. 4. Perfluoroalkyl substances (PFASs), flame retardants and cyclic volatile methylsiloxanes in indoor air in Uppsala, Sweden : occurrence and human exposure assessment

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Bo Sha; [2017]
    Keywords : passive air sampling; SIPs; indoor air; PFAS; flame retardants; siloxanes; human exposure;

    Abstract : Indoor air samples were collected from three buildings located at the Swedish University of Agricultural Science (SLU) campus in Ultuna, Uppsala, Sweden and from residences of nine volunteers working in the three buildings. Sorbent-impregnated polyurethane foam (SIP) disk passive air samplers were deployed in different types of rooms in the three buildings including computer room (n = 1), labs (n = 3), lecture rooms (n = 3), offices (n = 8) and dining areas (n = 3) and homes (n = 9) of the volunteers between September and November in 2016.

  6. 5. Assessment on Groundwater Contamination from a Former Hard Chromium Plating Site in Iggesund

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Isabell Alnehem; [2016]
    Keywords : ;

    Abstract : Before the persistent and toxicological properties of perfluoroalkyl and polyfluoroalkyl substances (PFASs) were known they were used worldwide. The thermal and chemical stability from the carbon-fluorine bond makes these substances desirable for industrial applications. READ MORE
