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

    Författare :Maria Lagerström; Ann-Kristin Eriksson Wiklund; Erik Ytreberg; Kent Salo; Andrew Turner; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Impacts of recreational boating in coastal seascapes and implications for management

    Författare :Jenny Egardt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; leisure boats; management; environmental impact; marine national park;

    Sammanfattning : Kosterhavet National Park, a marine protected area on the Swedish west coast, is a popular destination for tourists and attracts over half a million visitors annually. Many of the tourists arrive by boat, and the natural harbours are frequently visited. LÄS MER

  4. 3. 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

  5. 4. Use and environmental impact of antifouling paints in the Baltic Sea

    Författare :Maria Alexandra Bighiu; Ann-Kristin Eriksson-Wiklund; Bethanie Carney Almroth; Manu Soto; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boats; antifouling paints; metals; XRF; in situ; caging; Theodoxus fluviatilis; toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Biocide-based antifouling (AF) paints are the most common method for preventing biofouling, i.e. the growth of algae, barnacles and other organisms on boat hulls. AF paints for leisure boats are predominantly based on copper (Cu) as the main biocide, with zinc (Zn) present as a pigment and stabilizer. LÄS MER

  7. 5. Exploring the (re-)configuration of environmentally unsustainable practices - Antifouling in the Baltic Sea

    Författare :Bianca Koroschetz; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable consumption; reconfiguration of practices; linkages Fritidsbåtar miljöaspekter; Konsumtion miljöaspekter; Konsumentpsykologi miljöaspekter;

    Sammanfattning : This thesis explores how to (re-)configure environmentally unsustainable practices into more sustainable forms in the empirical context of leisure boat antifouling. Current antifouling practices predominantly involve the use of biocide-based paint to avoid the adherence of marine organisms to boats. LÄS MER
