  1. 21. Identification and Characterisation of Hydroxylated PCB and PBDE Metabolites in Blood : Congener specific synthesis and analysis

    Författare :Tina Malmberg; Åke Bergman; Olov Sterner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Sammanfattning : Hydroxylated polychlorinated biphenyls (OH-PCBs) are known metabolites of polychlorinated biphenyls (PCBs) in many mammalian, bird and fish species. Among those, certain OH-PCB congeners are strongly localised in the blood compartment of humans and wild animals. LÄS MER

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

    Författare :Patricia Moreira Bastos; Åke Bergman; Leif Kronberg; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxidation; Persistence; Photolysis; QSPR; BFRs; PBDEs; OH-PBDEs; Chemistry; 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. 23. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment

    Författare :Karin Norström; Åke Bergman; Mats Olsson; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bis 4-chlorophenyl sulfone; PCB methyl sulfone; Baltic Sea; Environmental chemistry; Miljökemi;

    Sammanfattning : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. LÄS MER

  7. 25. Hydrolysis and photolysis of brominated flame retardants and some traditional persistent organic pollutants : Reactivity as a tool in fate assessement of chemicals

    Författare :Sara Rahm; Åke Bergman; Stellan Marklund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Sammanfattning : An organic compound that remains in the environment for a long time is regarded as a persistent organic pollutant (POP). Still, persistency is not a well defined property with a firm definition. Instead it is a conceptual property of chemicals for which DDT and PCB are typical representatives. LÄS MER
