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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Greta Smedje; Uppsala universitet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Uve Matson; [2004]
    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. Performance-based design of ventilation systems. Potential and limitations regarding indoor air quality

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ragib Kadribegovic; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; prescriptive design; indoor air quality; air cleaning; energy efficiency; performance-based design; recirculation;

    Abstract : It has been increasingly common to design for increased ventilation rates above legislative requirements specified in building codes and other norms as the most optimum way to improve indoor air quality. However, this concept has recently been challenged, for example, by studies demonstrating that the emissions or pollution from used traditional particle filters increases proportionally with air flow through the filter.

  4. 4. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools

    University dissertation from Örebro : Örebro University

    Author : Josefin Persson; Örebro universitet.; [2018]
    Keywords : 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.

  5. 5. Chemical emissions from building structures emission sources and their impact on indoor air

    University dissertation from Umeå : Umeå Universitet

    Author : Annika Glader; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE
