22. Methylmercury in boreal freshwater food webs
Sammanfattning : Mercury (Hg) and bioaccumulation of its organic form methylmercury (MeHg) has long been regarded as a global issue for human and wildlife health. This is of particular concern for Sweden, where forest harvests and wetlands remain hotspots of MeHg export to boreal freshwaters. LÄS MER
23. Role of sediment organic matter quality and benthic organisms for the fate of organic contaminants in marine systems
Sammanfattning : Marine sediments constitute important contaminant sources within our environment. Organic matter input to marine sediments changes seasonally in terms of both quantity and quality, and has been profoundly altered in many coastal areas due to eutrophication. LÄS MER
24. Persistent organic pollutants in benthic foodwebs
Sammanfattning : Concentrations of persistent organic pollutants (POPs) in aquatic biota are dependent on several factors both on individual and on system level. Bioaccumulation of POPs in pelagic biota in lakes as well as fish in streams has been shown to be dependent on nutrient regime of the system. LÄS MER
25. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities
Sammanfattning : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis). LÄS MER
