  2. 1. Use and environmental impact of antifouling paints in the Baltic Sea

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

    Abstract : 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. READ MORE

  4. 2. Studies of fish responses to the antifoulant medetomidine

    Author : Anna Lennquist; Göteborgs universitet; []
    Keywords : antifouling; fish; medetomidine; ecotoxicology; biomarker;

    Abstract : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. READ MORE

  5. 3. 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.

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

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

    Abstract : 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). READ MORE

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

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

    Abstract : 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. READ MORE
