    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Arctic charr (Salvelinus alpinus L.) is a salmonid that is well adapted to cold waters and is commonly farmed in open net cages. A breeding program has enabled a relatively large production in Sweden, providing a continuous supply of fresh fish to the market. LÄS MER

  3. 12. Improved Assessment in Environmental Monitoring of POPs : Using monitoring data from the aquatic ecosystem and human milk

    Författare :Elisabeth Nyberg; Anders Bignert; Jochen Mueller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental monitoring; temporal trends; power analysis; sampling strategy; PCBs; DDTs; HCHs; HCB; PCDD Fs; fish; bird eggs; blue mussels; human milk; miljökemi; Environmental Chemistry;

    Sammanfattning : The thesis deals with several aspects of monitoring of persistent organic contaminants (POPs) in biological matrices, for example choice of sample, sampling design, and statistical treatment of data both for temporal and spatial trends and for compliance towards a set target value. The efficiency has been evaluated through statistical power analyses. LÄS MER

  4. 13. Sediment resuspension : Impacts and extent of human disturbances

    Författare :Ingrid Tjensvoll; Clare Bradshaw; Torgeir Heggelund Bakke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Resuspension of sediment by anthropogenic disturbances is a concern due to the impacts it has on organisms and ecosystems. Bottom trawling is one major cause of sediment resuspension. A field study showed that a small trawl created a sediment plume 120 - 150 m wide and 15-18 m high (Paper 1). The sediment in the same study was highly contaminated. LÄS MER
