6. Use and environmental impact of antifouling paints in the Baltic Sea
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. Integrative approaches in ecotoxicological testing: Implications for biomarker development and application
Sammanfattning : Ecotoxicology aims to understand toxic effects of chemicals in the environment. Effects can be observed at different levels of the biological organization, from molecular to ecosystem level. LÄS MER
8. Redskap för lärande? : Återkoppling i samhällskunskap på gymnasiet
Sammanfattning : This dissertation explores written and oral feedback in different contexts. The study is based on interviews with five Swedish teachers in Civics and on observations of their way of giving feedback in the classroom. Furthermore, teachers’ comments on the students’ written tasks were examined. LÄS MER
9. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats
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.

10. Pharmaecological perspectives : Exposure studies using coastal Baltic Sea organisms
Sammanfattning : This thesis investigates the effects of pharmaceutical substances on coastal Baltic Sea organisms. Despite an increasing awareness of the occurrence of pharmaceuticals in various aquatic compartments, current knowledge of their possible effects on non-target organisms is limited. LÄS MER
