  3. 3. Marine Seaweed Invasions the Ecology of Introduced Fucus evanescens

    Detta är en avhandling från Stockholm : Botaniska institutionen

    Författare :Sofia A. Wikström; Stockholms universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological invasions; marine; seaweed; algae; herbivory; enemy release hypothesis; phlorotannins; anti-fouling; Fucus evanescens; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi 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.

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

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm Univeristy

    Författare :Jenny Karlsson; Stockholms universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-fouling paints; Toxicity tests; Hazard identification; Sediment toxicity; Ceramium tenuicorne; Nitocra spinipes; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; tillämpad miljövetenskap; Applied Environmental Science;

    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. 5. Corrosion-induced release of zinc and copper in marine environments

    Detta är en avhandling från Stockholm : KTH

    Författare :Jan Sandberg; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; TECHNOLOGY Materials science Other materials science; TEKNIKVETENSKAP Teknisk materialvetenskap Övrig teknisk materialvetenskap;

    Sammanfattning : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. LÄS MER
