1. An evaluation of sources contributing to urban runoff pollution
Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER
2. Polybrominated diphenylethers in the environment - Local and long range transport
Sammanfattning : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. LÄS MER
3. Suspended solids and indicator bacteria in stormwater runoff : Sources of bias in field measurements
Sammanfattning : Stormwater quality monitoring and control is a prerequisite for sustainable water resources management in urban areas. Stormwater monitoring programs are based on general water sampling guidance and, in the absence of standard procedures, employ various sampling and analytical methods. LÄS MER
4. Urban Surfaces as Sources of Stormwater Pollution : An Evaluation of Substances Released from Building Envelopes
Sammanfattning : Stormwater is an important transport pathway for pollutants from the urban environment into receiving water bodies, and, thus, it contributes to the deterioration of urban surface waters. The aim of this Licentiate thesis was to advance the understanding of the contributions of urban stormwater pollutants from building surface materials, and evaluate the implications for stormwater quality.

5. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency
Sammanfattning : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. LÄS MER
