  3. 17. Indoor environment and air quality in hospital units : Symptoms and signs

    Författare :Klas Nordström; Uppsala universitet; []
    Nyckelord :Medical sciences; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : Indoor environment may influence the occurrence of symptoms such as eye, skin and upper airway irritation, headache and fatigue. The aim of the dissertation was to study relations between subjective indoor air quality, such symptoms, clinical signs from the nose and the eyes and the physical indoor environment, in particular the effect of dampness, type of building, and air humidification.
