  1. 1. Synthesis of organobromines as a tool for their characterisation and environmental occurrence assessment

    Författare :Andreas Rydén; Göran Marsh; Vladimir Nikiforov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polybrominated diphenyl ethers; Brominated diphenyliodoniums salts; PBDEs; OH-PBDEs; MeO-PBDEs; Synthesis; Analysis; Abbreviations; Metabolites; Marine natural products; E-waste; Brominated flameretardants; miljökemi; Environmental Chemistry;

    Sammanfattning : Polybrominated diphenyl ethers (PBDEs) have been intensively used as flame retardants (FRs) and have become ubiquitous environmental pollutants. PBDEs form hydroxylated PBDEs (OH-PBDEs) as metabolites. Further, some OH-PBDEs and methoxy-PBDEs (MeO-PBDEs) are natural products. LÄS MER

  3. 2. Environmentally relevant chemical disruptors of oxidative phosphorylation in Baltic Sea biota : Exposure and toxic potentials

    Författare :Anna-Karin Dahlberg; Lillemor Asplund; Åke Bergman; Göran Marsh; Patrik Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxidative phosphorylation; OH-PBDEs; MeO-PBDEs; PBDEs; long-tailed duck Clangula hyemalis ; Baltic herring Clupea harengus ; Baltic blue mussel Mytilus trossulus x Mytilus edulis ; Baltic Sea; miljökemi; Environmental Chemistry;

    Sammanfattning : This thesis focuses on toxicity and occurrence of hydroxylated polybrominated diphenyl ethers (OH-PBDEs) in Baltic Sea biota. The aims were to assess OH-PBDEs potency for disruption of oxidative phosphorylation (OXPHOS) and determine their and related compounds exposure in Baltic blue mussel, herring and long-tailed duck.

  4. 3. Trends and exposure of naturally produced brominated substances in Baltic biota - with focus on OH-PBDEs, MeO-PBDEs and PBDDs

    Författare :Karin Löfstrand; Lillemor Asplund; Åke Bergman; Adrian Covaci; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Batlic Sea; Natural production; OH-PBDE; MeO-PBDE; PBDD; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : The semi-enclosed and brackish Baltic Sea has become heavily polluted by nutrients, anthropogenic organic and inorganic chemicals via human activities. Persistent organic pollutants (POPs) have been thoroughly investigated due to their linkage to toxic effects observed in Baltic biota. There has been far less focus on semi-persistent pollutants e.

  5. 4. Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

    Författare :Anna Malmvärn; Lillemor Asplund; Åke Bergman; Bert van Bavel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; hydroxylated polybrominated diphenyl ethers; methoxylated polybrominated diphenyl ethers; Baltic Sea; algae; natural production; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. LÄS MER

  7. 5. Monitoring persistent organic pollutants (POPs) in sub-Arctic and Arctic marine mammals, 1984 - 2009

    Författare :Anna Rotander; Bert van Bavel; Magnus Engwall; Jacob de Boer; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; marine mammals; North Atlantic Ocean; POPs; temporal variations; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Miljökemi; Environmental Chemistry;

    Sammanfattning : The Arctic has become an important indicator region for assessing persistence and bioaccumulation properties of persistent organic pollutants (POPs). This thesis is aimed at evaluating the occurrence of persistent halogenated POPs in seven species of sub-Arctic and Arctic marine mammals over a 25-year period. LÄS MER
