  1. 11. In vivo dosimetry of some important industrial chemicals by measurement of their reaction products with hemoglobin

    Författare :Hermes Licea Pérez; Åke Bergman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Biology; fysikalisk biologi;

    Sammanfattning : Hemoglobin adduct measurements provide a useful tool for the development of models for risk assessment of chemicals. The measurements can be used to identify reactive metabolites and to determine the in vivo doses of these metabolites. LÄS MER

  3. 12. Assessment of Environmental Pollutants in Humans from Four Continents : Exposure levels in Slovakia, Guinea-Bissau, Nicaragua and Bangladesh

    Författare :Linda Linderholm; Åke Bergman; Maria Athanasiadou; Kristina Jakobsson; Myrto Petreas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; POPs; PCB; DDT; PBDE; HCH; metabolites; human exposure; children s exposure; placental transfer; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : Humans are continuously exposed to complex mixtures of anthropogenic chemicals. This thesis focus on human exposure to persistent organic pollutants (POPs). POPs ability to bioaccumulate and biomagnify together with the extensive historical use of POPs in e.g. LÄS MER

  4. 13. 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. 14. 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

  7. 15. 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
