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

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Författare :Andreas Rydén; Stockholms universitet.; [2013]
    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; Environmental Chemistry; miljökemi;

    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

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

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Anna-Karin Dahlberg; Stockholms universitet.; [2015]
    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; Environmental Chemistry; miljökemi;

    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.

  3. 3. Comparison of experimentally and theoretically determined oxidation and photochemical transformation rates of some organohalogens to promote prediction of persistence

    Detta är en avhandling från Stockholm : Department of Environmental Chemistry, Stockholm University

    Författare :Patricia Moreira Bastos; Stockholms universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxidation; Persistence; Photolysis; QSPR; BFRs; PBDEs; OH-PBDEs; MEDICINE Chemistry; MEDICIN Kemi; miljökemi; Environmental Chemistry;

    Sammanfattning : The diversity of choices we have to make everyday influence our environment and ourselves in more ways than most of us realise. Anthropogenic substances, such as flame retardants, date back as early as 450 BC when the Egyptians used alum to reduce flammability. LÄS MER

  4. 4. PBDEs in the Environment Time trends, bioaccumulation and the identification of their successor, decabromodiphenyl ethane

    Detta är en avhandling från Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Författare :Amelie Kierkegaard; Stockholms universitet.; [2007]
    Nyckelord :PBDE; BDE209; dietary absorption; metabolism; debromination; bioaccumulation; decabromodiphenyl ethane; decabromodiphenyl ether; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Polybrominated diphenyl ethers (PBDEs) are important chemical flame retardants, but also environmental pollutants. Their bromine substitution lends them a different bioaccumulation behaviour than the better studied organochlorines.The contamination of a Swedish lake with lower brominated BDEs was assessed by a retrospective study of pike.

  5. 5. Brominated flame retardants and perfluoroalkyl acids in Swedish indoor microenvironments Implications for human exposure

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Justina Björklund; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. LÄS MER
