  1. 1. Occupational exposure to brominated flame retardants : With emphasis on polybrominated diphenyl ethers

    Författare :Kaj Thuresson; Åke Bergman; Peter Fürst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; occupational exposure; Brominated flame retardants; polybrominated diphenyl ethers; air and serum concentrations; decabromodiphenyl ether; Environmental chemistry; Miljökemi;

    Sammanfattning : Brominated flame retardants (BFRs) are a diverse group of chemicals, which are used to slow down or inhibit the development of fires. BFRs are incorporated into a wide range of consumer products that are considered as potential fire hazards, such as TV-sets, household appliances, computers, and textiles. LÄS MER

  3. 2. Polybrominated diphenyl ethers and Tetrabromobisphenol A : Chemical synthesis, X-ray crystallography and Photochemical degradation

    Författare :Johan Eriksson; Åke Bergman; Lars Eriksson; Mats Tysklind; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Sammanfattning : In the 1960s’ several manmade chemicals were detected in the environment, far from their sources. The most well known, and most likely those with the largest impact on the society, were DDT and its related compounds, and PCBs. These anthropogenic compounds were characterised as persistent organic pollutants (POPs). LÄS MER

  4. 3. Synthesis and characterization of highly polybrominated diphenyl ethers

    Författare :Daniel Teclechiel; Göran Marsh; Vladimir Nikiforov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : Polybrominated diphenyl ethers (PBDEs) make up an important class of brominated flame retardants. The present production is mainly concentrated to DecaBDE but until recently also a significant production of PentaBDE and OctaBDE took place, leaving us with a large number of different PBDE congeners.

  5. 4. Metabolism of some polychlorinated biphenyl and polybrominated diphenyl ether congeners in the rat

    Författare :Anna Sandholm; Bert-Ove Lund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : For the understanding of the metabolic fate of xenobiotics, in vivo studies are needed. In this thesis the metabolism of CB-28 and CB-77 and BDE-209 in the rat are determined. In addition, pharmacokinetic studies of CB-28 and BDE- 209 are included. The compounds were radiolabelled and their excretion and tissue distribution determined. LÄS MER

  7. 5. Gas chromatography and mass spectrometry of polybrominated diphenyl ethers

    Författare :Jonas Björklund; Jacob De Boer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The aim of this thesis has been to develop accurate and sensitive analytical methods for the determination of polybrominated diphenyl ethers (PBDEs). It focuses on the development and optimization of gas chromatographic and mass spectrometric analysis of PBDE. LÄS MER
