    Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER

  5. 4. Transport of perfluoroalkyl acids from the ocean to the atmosphere via sea spray aerosol

    Författare :Bo Sha; Ian Cousins; Matthew Salter; Jana Johansson; Jonathan P. Benskin; Cora Young; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perfluoroalkyl acids; PFAAs; Per- and polyfluoroalkyl substances; PFAS; atmospheric transport; sea spray aerosol; industrial sources; Environmental Sciences; miljövetenskap;

    Sammanfattning : Perfluoroalkyl acids (PFAAs) are a subgroup of per- and polyfluoroalkyl substances (PFAS) that have been widely used in commercial and industrial applications. PFAAs are very persistent in the environment and some can bioaccumulate and have adverse health effects on human health. LÄS MER

  7. 5. Biostratigraphic implications of Neogene diatom abundances in the Norwegian Sea, the North Atlantic and the western North Pacific

    Författare :Per Bodén; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of three separate articles and are mainly concerned with the taxonomy of species from the genus Thalassiosira and quantitative diatom biostratigraphy in three oceanic regions of the northern hemisphere. The study material consists of Ocean Drilling Program (ODP) Holes 642B, 642C and 644A at about 67°N in the Norwegian Sea, Deep Sea Drilling Project (DSDP) Hole 552A at 56 N in the North Atlantic, and DSDP Site 578 at 34°N in the northwest Pacific.
