  1. 6. Sorption of perfluorinated and polyfluorinated alkylated substances (PFASs) in the subsurface of an industrial site in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Carl Sköld; [2019]
    Keywords : Sorption; soil-water partitioning; Kd; PFOS; PFOA; PFHxS; Sorption; fördelningskoefficient; Kd; PFOS; PFOA; PFHxS;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of emerging chemicals which havereceived increasing attention due to their toxicity, persistent properties, and global distribution.In this study, sorption coefficients (Kd and KOC) of PFASs in an industrial site in Sweden wereevaluated.

  3. 7. Removal of poly- and perfluoroalkyl substances from water using the BDD electrode

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

    Author : Winnie Nassazzi; [2018]
    Keywords : PFAS; drinking water; advanced oxidation processes; membrane reject water; electrochemical treatment; BDD electrode;

    Abstract : Poly-and perfluoroalkyl substances (PFASs) have been used for a wide range of purposes due to their unique properties. Unfortunately, these compounds have been associated with several adverse health effects and high persistence in the environment, therefore, creating a need for their elimination from the environment.

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a diverse group of persistent organic pollutants. PFASs have a wide area of applications such as stain repellent for paper, textile, furniture and industrial products such as aqueous film forming foams (AFFFs) used for firefighting. READ MORE

  5. 9. Per- and polyfluoroalkyl substances (PFASs) in Swedish waters

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

    Author : Johanna Hedlund; [2016]
    Keywords : per- and polyfluoroalkyl substances; PFAS; fire training; firefighting foam; landfill; leachate; groundwater; surface water; effluent; drinking water;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) is a group of persistent, bioaccumulative and toxic pollutants. PFASs are widely used in industrial processes and products such as water- and fat repelling surfaces in clothes, paints and paper. They are also used in certain types of firefighting foams and have been found in ski waxes. READ MORE

  6. 10. Calibration and Application of Passive Sampling in Drinking Water for Perfluoroalkyl Substances

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Caroline Persson; [2015]
    Keywords : Perfluoroalkyl substances PFASs ; passive sampling; Polar organic compound integrative sampler POCIS ; sampling rate; calibration; application; drinking water; Perfluoroalkylsubstanser PFAS ; passiv provtagning; Polar organic compound integrative sampler POCIS ; provtagningsshastighet; kalibrering; tillämpning;

    Abstract : Perfluoroalkyl substances (PFASs) are global environmental contaminants and a need for monitoring levels has arisen due to their persistency and their ability to bioaccumulate. One relatively novel method of monitoring for both long and short time intervals and generating time-weighted average (TWA) concentrations is passive sampling for which no power, maintenance and supervision is required.
