1. Persistent organic pollutants in the atmosphere - spatial and temporal variations
Abstract : In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region.

2. Polybrominated diphenylethers in the environment - Local and long range transport
Abstract : 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. READ MORE

3. Fractionation of the stable silicon isotopes : analytical method developments and selected applications in geochemistry
Abstract : During the last few decades, variations in the 'natural' isotopic abundances of stable elements (termed 'fractionation') have received considerable interest from the scientific community. Though analytical methods and techniques for the measurement of isotopic abundances with adequate figures of merit have been available for light elements (e.g. READ MORE

4. Building a map of the breast cancer proteome - Strategies to increase coverage
Abstract : Amongst the various –omics sciences, proteomics has the highest potential for functional characterization and consequently can contribute significantly to the field of cancer research. In particular, the focus of this thesis is on breast cancer. READ MORE

5. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures
Abstract : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. READ MORE
