  1. 1. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

    Författare :Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Uptake Processes of Polychlorinated Biphenyls at the Base of the Pelagic Food Web

    Författare :Anna Sobek; Örjan Gustafsson; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCBs; plankton; equilibrium partitioning; uptake; aquatic food web; Environmental chemistry; Miljökemi;

    Sammanfattning : Hydrophobic organic contaminants (HOCs) are persistent, toxic to biota and are known to bioaccumulate in food webs. In this thesis, polychlorinated biphenyls (PCBs) were used as model compounds to study the fate and transport of HOCs in the aquatic environment. LÄS MER

  5. 4. Assessment of organochlorine contamination in the aquatic environment of Latvia with perch and heron as biomarkers

    Författare :Karlis Valters; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Chemistry; miljökemi;

    Sammanfattning : Polychlorinated biphenyls (PCBs), DDT, DDT transformation products, and several other organochlorine substances (OCS) have been analysed in numerous species and matrices from different parts of the world including Arctic environments. However, knowledge on levels and distribution of OCS is still lacking for many regions world-wide including the Eastern Europe in general. LÄS MER
