  1. 11. Analysis of Per- and Polyfluorinated Substances (PFASs) in Eggs and Hen Food from Örebro County, Sweden

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Theolinda Hanell; [2015]
    Keywords : ;

    Abstract : Perfluorinated alkyl substances (PFASs) have been used for various purposes for decades and have shown to have toxic properties. The main source of human exposure seems to be through the dietary where eggs, fish, meat and dairy products are the main sources. READ MORE

    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

  4. 13. Transport of per- and polyfluoroalkyl substances in soil and groundwater in Uppsala, Sweden

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

    Author : Sofia Bergström; [2014]
    Keywords : PFASs; PFOS; perfluoroalkyl substances; groundwater; soil; surface water; river water; drinking water; aqueous film forming foams;

    Abstract : In recent years, per- and polyfluoroalkyl substances (PFASs) have received increasing public attention due to their persistence, bioaccumulation potential and toxicity to humans and wildlife. PFASs are widely used in various products including surfactants in paper, textiles, and aqueous film forming foams (AFFFs). READ MORE

  5. 14. 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

  6. 15. Effects of perfluorinated compounds on hepatic fatty acid oxidation in avian embryos using a tritium release assay

    University essay from Örebro universitet/Akademin för naturvetenskap och teknik

    Author : Ola Westman; [2009]
    Keywords : PFOS; avian toxicology;

    Abstract : The large use of perfluorinated compounds (PFCs) to produce fluoropolymers in consumer and industrial applications, including insecticides, plastics, non-stick surfaces and fire fighting foams has led to a well known widespread occurrence and high concentrations are found in wild life including avian species. For instance, concentrations of perfluorooctane sulfonate (PFOS) in eggs from the common guillemot in the Baltic Sea are among the highest in the Nordic environment. READ MORE
