11. Method for measurement of exposure to electrophiles : Strategy for identification and exposure estimation using N-terminal haemoglobin adducts
Sammanfattning : We are exposed to many chemicals in our everyday life. Some of these chemicals could pose risks for our health. To reduce such risks, it is important to know what we are exposed to, how much, and how toxic the chemicals are. LÄS MER
12. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER
13. Estimating children’s exposure to per- and polyfluoroalkyl substances
Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are highly stable, surface active chemicals, which are water- and oil/stain-repellent. Because of their unique properties, PFASs are widely used in consumer products. LÄS MER
14. Characterization of the MRI patient exposure environment and exposure assessment methods for magnetic fields in MRI scanners
Sammanfattning : Magnetic resonance imaging (MRI) has become one of the most common imaging modalities available in modern medicine, and it is an indispensable diagnostic tool thanks to the unparalleled soft-tissue contrast and high image resolution. It is also a unique exposure environment consisting of a complex mix of magnetic fields. LÄS MER
15. Setting occupational exposure limits : Practices and outcomes of toxicological risk assessment
Sammanfattning : Occupational Exposure Limits (OELs) are used as an important regulatory instrument to protect workers’ health from adverse effects of chemical exposures. The main objective of this thesis is to study risk assessment practices in the setting of OEL in order to produce knowledge that will help improve the consistency and transparency of OELs. LÄS MER
