  2. 6. The role of the mitochondrion in organotin-induced T-cell apoptosis

    Author : Hélène Stridh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Apoptosis plays a central role in the development and the function of the immune system. The cell death program can, however, be inappropriately activated or suppressed under pathological conditions. Several toxins have been shown to interfere with intra-thymic processes, thereby contributing to autoimmune disorders. READ MORE

  4. 7. Bioaccumulation and biological effects of organic contaminants in Icelandic coastal waters

    Author : Halldóra Skarphéđinsdóttir; Åke Granmo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Miljögifter; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : In this thesis, studies on organic contamination from both diffuse and point sources in Icelandic waters are presented. The aim was to investigate bioaccumulation and biological effects of the contaminants or biomarkers, and their applicability in environmental marine coastal monitoring, especially in areas with moderate or low levels of contamination such as Iceland.

    Abstract : Ecosystem services constitute a precondition for human welfare and survival. This concept has also become increasingly popular among both scientists and policymakers. Several initiatives have been taken to identify and value ecosystem services. READ MORE

  6. 9. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats

    Author : Maria Lagerström; Ann-Kristin Eriksson Wiklund; Erik Ytreberg; Kent Salo; Andrew Turner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antifouling paint; XRF; leisure boat; recreational boating; copper; zinc; tributyltin; organotin compounds; risk assessment; biocide; metals; release rate; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biocidal antifouling (AF) paints is the most common way to prevent fouling on leisure boat hulls. The main aim of this thesis was to investigate the pathways through which AF biocides, past and present, may reach the environment through their use on leisure boats and to improve the risk assessment of biocidal AF paints intended for amateur use.

  7. 10. Barnacle Bioadhesive Bonding Formation, Strength and Control

    Author : Mattias Berglin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barnacle adhesive plaque; poly dimethylsiloxane ; fouling release coatings; bioadhesion; marine biofouling;

    Abstract : The current technology for keeping ship hulls free of marine biofouling requires the use of toxic compounds such as copper, organic biocides and tributyl tin (TBT). The compounds that are released have been shown to have negative effects on non-target organisms, and a worldwide ban of TBT is currently being introduced. READ MORE
