  1. 1. 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

  3. 2. 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

  4. 3. Integrating biochemical and growth responses in ecotoxicological assays with copepods

    Författare :Ulrika Dahl; Magnus Breitholtz; Peter Matthiessen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental toxicology; Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The understanding of effects of chemical exposure in nature is lagging behind. Predictions of harmful effects of chemicals on aquatic organisms rely mainly on ecotoxicity tests. LÄS MER

  5. 4. A different approach to ecotoxicological characterisation of sewage effluent; using sensitive and ecologically relevant methods

    Författare :Elin Lundström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Abstract Characterisation is used for quality assurance of effluent released into the environment. A different characterisation approach was in this thesis used for more sensitive and ecologically relevant whole effluent assessment. LÄS MER

  7. 5. Population modeling using harpacticoid copepods : Bridging the gap between individual-level effects and protection goals of environmental risk assessment

    Författare :Elin Lundström Belleza; Magnus Breitholtz; Annemette Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population modeling; Eco toxicity tests; Environmental risk assessment; Harpacticoid copepods; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : To protect the environment from contaminants, environmental risk assessment (ERA) evaluates the risk of adverse effects to populations, communities and ecosystems. Environmental management decisions rely on ERAs, which commonly are based on a few endpoints at the individual organism level. LÄS MER
