  3. 2. Release rates and toxicity of metals from anti-fouling paints and the role of chemical speciation

    Författare :Erik Ytreberg; Britta Eklund; Magnus Breitholtz; Christina Rudén; Ingela Dahllöf; Stockholms universitet; []
    Nyckelord :Anti-fouling paints; Toxicity test; Ceramium tenuicorne; Nitocra spinipes; Copper; Zinc; Free Ion Activity Model FIAM ; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The aim of this doctoral thesis was to investigate and improve the risk assessment of anti-fouling paints. A new method, the Petri-dish method, was developed to determine release rates of copper and zinc from anti-fouling paints (Paper I). LÄS MER

  4. 3. Hazard Identification of Anti-fouling Paints and Contaminated Sediments by the Use of Biological Tests in Brackish Water

    Författare :Jenny Karlsson; Britta Eklund; Magnus Breitholtz; Göran Dave; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-fouling paints; Toxicity tests; Hazard identification; Sediment toxicity; Ceramium tenuicorne; Nitocra spinipes; Environmental engineering; Miljöteknik; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Ecotoxicological test methods are important tools in environmental risk assessment to investigate possible adverse effects that chemical substances may cause to aquatic ecosystems. The main aim of this doctoral thesis was to identify potential toxicity (hazard) of anti-fouling compounds and paints as well as contaminated sediments. LÄS MER

  5. 4. Improved Techniques for Protein Analysis Focusing on Membrane Proteins and Hydrophobic Peptides

    Författare :Theres Redeby; Åsa Emmer; Jonas ergquist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integral membrane proteins; Hydrophobic peptides; Sample handling; MALDI-TOF-MS; Structured sample support; CE; fraction collection; microchannel; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis, the vital cell functions performed by integral membrane proteins (IMPs) are briefly discussed. Such proteins are under-represented in most protein studies due to the hydrophobic nature of IMPs, which seriously complicate their solubilization, sample handling, preparation, separation and analysis.

  7. 5. Seaweed in the tropical seascape : Importance, problems and potential

    Författare :Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. LÄS MER
