  1. 1. The indoor environment in schools : Respiratory effects and air quality

    Author : Greta Smedje; Uppsala universitet; []
    Keywords : Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.

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

    Author : Uve Matson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; ventilation; air quality; 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. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Indoor air quality; volatile organic compounds; brominated flame retardants; organophosphate flame retardants; low-energy preschools; environmental certification; indoor dust; surface wipes;

    Abstract : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.
