    Sammanfattning : The Northern Fulmar (Fulmarus glacialis) is one of the most abundant seabirds in the Northern Hemisphere and the most abundant seabird on the Faroe Islands. Except from a few sporadic observations up until the 1950´s no study has focused on this species on the Faroe Islands. LÄS MER

    Sammanfattning : Plasma from workers at an electronic dismantling plant were analysed for tri- to heptaBDEs (brominated diphenyl ethers), during 18 months. The different exposed groups showed concentrations ranging from 0.06to 2.8 ng g-1 (l. LÄS MER

  4. 3. Spatial Vision in Birds: Anatomical investigation of spatial resolving power

    Sammanfattning : Avian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. LÄS MER

  5. 4. Human exposure to organohalogen compounds in the Faroe Islands

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCB; PBDE; OH-PCB; human serum; Environmental chemistry; Miljökemi;

    Sammanfattning : The Faroe Islands in the North Atlantic are part of the sub-Arctic region, a remote region far from industrial activity. In spite of this remoteness, the Islands are not a sanctuary: exposures and effects of environmental pollutants mar its natural beauty and wildlife. LÄS MER
