1. 1. Cu(I) stabilizing polymers for marine anti-fouling applications

   Författare :Alireza Movahedi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; coordinating polymers; copper; anti-fouling coatings; CuAAC; triazole; epoxide.; polymer functionalization; click chemistry;

   Sammanfattning : The growth of marine organisms on immersed surfaces in seawater is known as biofouling and causes several problems for marine transportation. The need to combat fouling is thus of great importance. Copper has to be used in extreme amounts to act as an efficient biocide. LÄS MER

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

5. 4. Marine Seaweed Invasions : the Ecology of Introduced Fucus evanescens

   Författare :Sofia A. Wikström; Lena Kautsky; Ove Eriksson; Paul Lavery; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological invasions; marine; seaweed; algae; herbivory; enemy release hypothesis; phlorotannins; anti-fouling; Fucus evanescens; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : Biological invasions are an important issue of global change and an increased understanding of invasion processes is of crucial importance for both conservation managers and international trade. In this thesis, I have studied the invasion of the brown seaweed Fucus evanescens, to investigate the fate and effect of a perennial, habitat-forming seaweed introduced to a coastal ecosystem.

7. 5. 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
