  1. 1. Quartz in Swedish iron foundries : exposure and cancer risk

    Author : Lena Andersson; Håkan Westberg; Gunilla Lindström; Per Gustavsson; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Case-control study; crystalline silica; exposure assessment; iron foundry; lung cancer; morbidity; occupational hygiene; respirable quartz; Enviromental Science; Miljövetenskap;

    Abstract : The aims of the studies underlying this thesis were to assess the exposure to quartz in Swedish iron foundries and to determine the cancer morbidity for Swedish foundry workers. A cohort of 3,045 foundry workers and a final measurement database of 2,333 number of samples was established. READ MORE

  2. 2. Aerosol Measurements as Applied for Exposure Characterization

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Abstract : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. READ MORE

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

    Author : Kerstin Winkens; Ian T. Cousins; Urs Berger; Robin Vestergren; Heather M. Stapleton; Stockholms universitet; []

    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

  4. 4. 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 : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  5. 5. Non-image-forming effects of light : Implications for the design of living and working environments

    Author : Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

    Abstract : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. READ MORE
