6. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden
Abstract : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. READ MORE

7. Application of scattered sunlight spectroscopy for quantification of gas emissions from anthropogenic and natural sources
Abstract : Monitoring of gas emissions from natural and anthropogenic sources is of importance due to their negative effects on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE

8. Environmental fate of chemicals released from consumer products : Multimedia modelling strategies
Abstract : The objective of this thesis was to assess the environmental fate and transport of chemicals emitted from consumer products through the development and application of modelling tools. The following hypotheses were tested: i) Multimedia fate models can be applied in a multistage assessment process to emerging chemicals when limited knowledge exists to identify the likely environmental fate and to direct further research; ii) the indoor environment acts as a source of anthropogenic substances in consumer products to the outdoor environment; and iii) chemical removal pathways in the indoor environment are important for the fate of organic chemicals in densely populated areas.

10. Aerosol Particle Sources Affecting the Swedish Air Quality at Urban and Rural Level
Abstract : During the last decades anthropogenic aerosol particles have attracted much attention due to their adverse health effects and their influence of climate change, and in Sweden, there are mainly three aerosol sources that affect the air quality; domestic wood combustion, traffic, and long distance transport, which includes new particle formation. This work concerns the characterization of these sources and an estimate of how much they contribute to the aerosol particle number (ToN) and mass concentrations (PM) in Swedish cities and at background locations.
