  1. 21. Effects of pH and Cation Composition on Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil Particles

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Malin Ullberg; [2015]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Soil; Partitioning coefficients; Partitioning; sorption; solution chemistry; electrostatic interaction; Visual MINTEQ; Perfluoroalkylsubstanser PFAS ; jord; partitioneringskoefficienter; sorption; lösningske- mi; elektrostatisk interaction; Visual MINTEQ;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) have drawn great attention recently, due to their environmental persistence, potential toxicity and global distribution. PFAS is a large family of substances, characterized by a perflourinated carbon chain and a functional group. READ MORE

  3. 22. Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

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

    Author : Anna Östlund; [2015]
    Keywords : PFASs; perfluoroalkyl substances; removal efficiency; granular activated carbon; GAC; anion exchange; AE; dissolved organic carbon; DOC;

    Abstract : Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. READ MORE

  4. 23. Effect of organic carbon, active carbon, calcium ions and aging on the sorption of per- and polyfluoroalkylated substances (PFASs) to soil

    University essay from Institutionen för geovetenskaper

    Author : Erika Schedin; [2013]
    Keywords : PFAS; sorption; soil; calcium; active carbon; organic carbon; aging.;

    Abstract : Per- and polyfluoroalkylated substances (PFASs) are a large group of organic chemicals that have gained an increased attention during recent years. Many of the compounds have shown to be persistent, toxic and bioaccumulating and they are found in water, soils, sediments, biota, animals and humans across the globe. READ MORE

  5. 24. Sustainable phosphorus management of horse paddocks at Julmyra
