  2. 1. Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

    Author : Anna Malmvärn; Lillemor Asplund; Åke Bergman; Bert van Bavel; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Trends and exposure of naturally produced brominated substances in Baltic biota - with focus on OH-PBDEs, MeO-PBDEs and PBDDs

    Author : Karin Löfstrand; Lillemor Asplund; Åke Bergman; Adrian Covaci; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Batlic Sea; Natural production; OH-PBDE; MeO-PBDE; PBDD; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Abstract : 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. 3. PBDEs in the Environment : Time trends, bioaccumulation and the identification of their successor, decabromodiphenyl ethane

    Author : Amelie Kierkegaard; Lillemor Asplund; Cynthia de Wit; Michael McLachlan; Jacob de Boer; Stockholms universitet; []
    Keywords : PBDE; BDE209; dietary absorption; metabolism; debromination; bioaccumulation; decabromodiphenyl ethane; decabromodiphenyl ether; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : 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.

  6. 4. Biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins in east Africa

    Author : Omar A. Amir; Per Berggren; Graham Pierce; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth; reproduction; feeding ecology; bycatch; organohalogen compounds; dolphins; Tursiops aduncus; Zanzibar; East Africa; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

    Abstract : This thesis examines the biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar, Tanzania, based on research conducted and samples collected between 2000 and 2008. Distribution and occurrence are described based on incidental catches (bycatch) in gillnet fisheries. READ MORE

  7. 5. Levels of organohalogen compounds in White-tailed sea eagles (Haliaeetus albicilla) in relation to reproduction impairment in the Bothnian Sea

    Author : Ulrika Nordlöf; Lillemor Asplund; Björn Helander; Yngve Zebuhr; Michael Mclachlan; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The white-tailed sea eagle (Haliaeetus albicilla) is in the top of the marine food chain and its existence in Sweden has been threatened several times. The species succeeded to recover from the deep decline in the 1970s when the exposure to persistent organic pollutants influenced the reproduction negatively. READ MORE
