  1. 11. 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.

  3. 12. Hydroxylated polybrominat­ed diphenyl ethers in Baltic Sea biota : Natural production, food web distribution and biotransformation

    Författare :Dennis Lindqvist; Lillemor Asplund; Walter Vetter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH-PBDEs; Baltic Sea; Biosynthesis; Environmental fate; Wildlife exposure; Metabolism; Analytical methods; Ceramium tenuicorne; Blue mussel; Gammarus spp.; Stickleback; Perch; Grey Seal; miljökemi; Environmental Chemistry;

    Sammanfattning : Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are naturally produced in aquatic ecosystems e.g. by algae. Many OH-PBDEs have been observed to be highly bioactive and to cause adverse effects through several pathways, e. LÄS MER

  4. 13. Neonatal Developmental Neurotoxicity of Brominated Flame Retardants, the Polybrominated Diphenyl Ethers (PBDEs)

    Författare :Henrik Viberg; Per Eriksson; Susan Schantz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; brominated flame retardants; polybrominated diphenyl ethers; PBDE; neonatal; development; neurotoxicity; behaviour; cholinergic system; Biologi; Biology; Biologi;

    Sammanfattning : This thesis examines developmental neurotoxic effects of polybrominated diphenyl ethers (PBDEs), PBDE 99, PBDE 153, and the fully brominated PBDE 209, after exposure during the newborn period in rodents. Our environment contains vast numbers of contaminants, including the flame retardants, PBDEs. LÄS MER

  7. 15. Large Volume Injection and Hyphenated Techniques for Gas Chromatographic Determination of PBDEs and Carbazoles in Air

    Författare :Petter Tollbäck; Conny Östman; Tuulia Hyötyläinen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; large volume injection; hyphenated techniques; LC-GC; GC-MS; mass spectrometry; GC; gas chromatography; carbazoles; PBDE; polybrominated diphenyl ethers; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis is based on studies in which the suitability of various gas chromatography (GC) injection techniques was examined for the determination of polybrominated diphenyl ethers (PBDEs) and carbazoles, two groups of compounds that are thermally labile and/or have high boiling-points. For such substances, it is essential to introduce the samples into the GC system in an appropriate way to avoid degradation and other potential problems. LÄS MER
