16. Environmental occurrence and behaviour of the flame retardant decabromodiphenyl ethane
Sammanfattning : The environmental occurrence and behaviour of the brominated flame retardant (BFR) decabromodiphenyl ethane (dbdpe) has only been studied to a limited extent. It is structurally similar to decabromodiphenyl ether (decaBDE), which makes it conceivable that dbdpe may also become an environmental contaminant of concern. LÄS MER
17. Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic
Sammanfattning : Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation interactions (ari) and aerosol cloud interactions (aci). LÄS MER
18. Floodplain remediation in agricultural streams : improved process understanding for reduced eutrophication
Sammanfattning : Anthropogenically modified headwater streams are key pathways for high nutrient and sediment loads from agriculture, sustaining eutrophication and poor water quality in downstream aquatic ecosystems. To address this challenge, stream mitigation strategies are required that complement in-field measures, to intercept internal pollutant loading in streams. LÄS MER
19. Grassed swales for urban storm drainage
Sammanfattning : This thesis investigates the environmental, economic and functional aspects of using grassed swales for the conveyance and treatment of stormwater. A grassed swale is a shallow, grass-lined channel. LÄS MER
20. Influential factors in simulations of future urban stormwater quality : Climate change, progressing urbanization and environmental policies
Sammanfattning : Climate change is regarded as one of the main future challenges implyingchanging hydrological conditions in urban areas. At the same time many urbanareas are expected to grow due to increasing population, which will most likelycause a higher level of urbanization. LÄS MER
