  1. 1. Radiosynthesis of Perfluoroalkyl Substances Chemical analysis, uptake, distribution, and partitioning studies

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Maria Sundström; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; PFBS; Environmental Chemistry; miljökemi;

    Abstract : Perfluoroalkyl substances (PFASs) are widely utilized manmade chemicals. Their properties have made them highly appreciated in a variety of industrial and consumer product applications, including fire-fighting foams, hydraulic fluids, as well as in cookware and food contact papers.

    Abstract : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. READ MORE

  3. 3. Comparative avian developmental toxicity of PFAAs

    University dissertation from Örebro : Örebro universitet

    Author : Marcus Nordén; Örebro universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chicken; herring gull; cormorant; PFAA; PFOS; PFOA; toxicity; levels; Biology; Biologi;

    Abstract : Perfluoroalkyl acids (PFAAs) are persistent organic pollutants that can commonly be found in environmental matrixes and wildlife from all over the globe. The PFAAs have been used in applications such as water and dirt repelling treatments for textiles, oil-resistant paper coatings and fire-fighting foams. READ MORE

  4. 4. Analysis and human levels of persistent perfluorinated chemicals

    University dissertation from Örebro : Örebro universitetsbibliotek

    Author : Anna Kärrman; Örebro universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; NATURAL SCIENCES Chemistry; NATURVETENSKAP 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

  5. 5. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Shahid Ullah; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental Science; PFASs; PFAAs; PFOA; PFOS; Precursor; FOSA; PAPs; Method development; LC-MS; SPE; Dietary sample; Drinking water; Human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE
