  1. 1. Cabin Air Quality in Commercial Aircraft Exposure, Symptoms and Signs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Torsten Lindgren; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; airline crew; aviation medicine; micro-organism; cabin air quality; air humidity; atopy; occupational exposure; environmental tobacco smoke ETS ; psychosocial work environment; Medicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. READ MORE

  2. 2. Ultrafine Particles in Indoor Air. Measurements and modelling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Uve Matson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air quality; ventilation; aerosols; airborne particles; outdoor air;

    Abstract : Clean air is one of the most fundamental human needs. Since people spen on average over 85% of their time indoors at work, home, school etc., human exposure to air pollution may mostly occur indoors. READ MORE

  3. 3. Impact of residential wood combustion on urban air quality

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)
