  2. 11. Method for measurement of exposure to electrophiles : Strategy for identification and exposure estimation using N-terminal haemoglobin adducts

    Author : Efstathios Vryonidis; Margareta Törnqvist; Hitesh Motwani; Isabella Karlsson; Marie Pedersen; Gabriele Sabbioni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Haemoglobin adducts; Electrophilic exposure; LC-MS; Adductomics; Acrylamide; Environmental Sciences; miljövetenskap;

    Abstract : 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. READ MORE

  4. 12. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Author : Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Abstract : 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. READ MORE

  5. 13. Estimating children’s exposure to per- and polyfluoroalkyl substances

    Abstract : 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. READ MORE

  6. 14. Characterization of the MRI patient exposure environment and exposure assessment methods for magnetic fields in MRI scanners

    Author : Jennifer Frankel; Jonna Wilén; Anders Garpebring; Johan Olsrud; Peter Lundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electromagnetic fields; exposure assessment; magnetic resonance imaging; switched gradient fields; radiofrequency fields; exposure metrics; radiofysik; radiation physics;

    Abstract : 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. READ MORE

  7. 15. Setting occupational exposure limits : Practices and outcomes of toxicological risk assessment

    Author : Linda Schenk; Christina Rudén; Alan Boobis; Michael Gilek; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Assessment Factor; DNEL; Euroepan Union; Occupational Exposure Limit; REACH; Risk Assessment; Regulatory Toxicology; SCOEL; Uncertainty Factor; Toxicology; Toxikologi;

    Abstract : 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. READ MORE
