  2. 1. Analysis and human levels of persistent perfluorinated chemicals

    Author : Anna Kärrman; Gunilla Lindström; Bert van Bavel; Ulf Järnberg; Jessika Hagberg; Lennart Hardell; Derek Muir; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. READ MORE

  4. 2. Organofluorine Mass Balance and Per- and Polyfluoroalkyl Substance Analysis of Environmental Samples and Human Blood

    Author : Rudolf Aro; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Christopher Higgins; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organofluorine mass balance; PFAS; extractable organofluorine; unidentified organofluorine; whole blood; surface water; effluent; sludge;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) have been linked to a range of negative health and environmental effects. Regulations limiting and/or banning the use of some of the legacy compounds have been introduced. Consequently, the production and use of PFAS has diversified. READ MORE

  5. 3. Ultra-short-chain perfluoroalkyl acids : Environmental occurrence, sources and distribution

    Author : Maria Björnsdotter; Ingrid Ericson Jogsten; Anna Kärrman; Leo W. Y. Yeung; Tom Harner; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFASs; TFA; TFMS; point sources; precursors; solar radiation; atmospheric oxidation; atmospheric deposition; flux; Arctic;

    Abstract : Ultra-short-chain perfluoroalkyl acids (PFAAs) is a group of highly fluorinated and very stable chemicals. Their small molecular structure in combination with the acidic functional group result in highly polar compounds and concern has been raised as these substances may threaten our drinking water supplies.

  6. 4. Optimizing nontarget workflows for identification of organic contaminants in various matrices

    Author : Florian Dubocq; Anna Kärrman; Thanh Wang; Juliane Hollender; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nontarget analysis; workflow optimization; statistical analysis; mass defect plot; organic contaminants; environmental matrices;

    Abstract : Since year 2000, production of chemicals around the world has more than doubled. Chemicals are used in many and diverse applications in our everyday life and even if their properties are useful, some can have a negative impact on environment and humans. READ MORE

  7. 5. Contribution of polyfluoroalkyl phosphate esters (PAPs) and other precursor compounds to perfluoroalkyl carboxylates (PFCAs) in humans and the environment

    Author : Ulrika Eriksson; Anna Kärrman; Bert van Bavel; Gunilla Lindström; Jonathan Martin; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAPs; precursors; PFCA; exposure; indoor dust; human serum; WWTP; bird eggs; Chemistry; Kemi;

    Abstract : Per-and polyfluoroalkyl substances (PFAS) are anthropogenic compounds that have been spread all over the world. The use of fluorotelomer compounds, short-chained homologues, and other PFASs with perfluorinated moieties has emerged recent years. READ MORE
