  1. 1. Ultrafine Particles in the Indoor Environment: Field and Laboratory Measurements

    Författare :Uve Matson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; indoor air; outdoor air; air quality;

    Sammanfattning : Clean air is one of the most fundamental human needs since poor air quality affects the health and the environment. It has been shown that people spend on average over 85 % of their time at work, home, school etc. Therefore, human exposure to air pollution may occur mostly indoors. Despite this fact, outdoor air pollution is also important. LÄS MER

  3. 2. WHAT ARE THE CHARACTERISTICS OF AIRBORNE PARTICLES THAT WE ARE EXPOSED TO? Focus on Indoor Environments and Emissions from Biomass Fired District Heating

    Författare :Aneta Wierzbicka; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles; indoor environments; biomass combustion;

    Sammanfattning : Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. LÄS MER

  4. 3. Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques

    Författare :Joakim Pagels; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; Teknik; Technological sciences; Indoor Air; In-Situ Measurement; Biomass Combustion; Morphology; Hygroscopic Growth; Volatility; TDMA; APS; ELPI; Respiratory Deposition; Fine Particles; Miljöteknik; kontroll av utsläpp; Ultrafine Particles;

    Sammanfattning : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. LÄS MER

  5. 4. Ultrafine Particles in Indoor Air. Measurements and modelling

    Författare :Uve Matson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; ventilation; air quality; outdoor air;

    Sammanfattning : 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. LÄS MER

  7. 5. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Författare :Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER
