  2. 1. 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

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

    Author : Uve Matson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; indoor air; outdoor air; air quality;

    Abstract : 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. READ MORE

  5. 3. Be Aware of the Indoor Air. Physicochemical Characterization of Airborne Fine Particles in Occupied Homes : Physicochemical Characterization of Airborne Fine Particles in Occupied Homes

    Author : Yuliya Omelekhina; Metalund; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrafine particles UFP ; PM2.5; Black carbon; Indoor sources; Occupied homes; energy renovation;

    Abstract : Negative health effects of exposure to particles of outdoor origin have been confirmed by epidemiological studies. In developed countries, we spend on average 65% of our time in our homes. Thus, the properties of airborne particles indoors need to be understood. READ MORE

  6. 4. Energy Efficient Air Quality Solutions for Vehicle Cabins

    Author : Dixin Wei; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate system; private car; measurements; particulate matters; CO2; simulations; air quality; air filter; UFP; filter status; energy use; vehicle cabin;

    Abstract : Maintaining a good air quality level is essential for reducing potential health risks for human beings. Vehicle cabin is one common environment where people spend increasing amount of time in modern societies. It’s an environment challenged by elevated pollutants from surrounding traffics, especially small particles like PM2. READ MORE

  7. 5. Environmental Factors in Relation to Asthma and Respiratory Symptoms among Schoolchildren in Sweden and Korea

    Author : Jeong-Lim Kim; Gunilla Wieslander; Dan Norbäck; Lena Elfman; Nils Åberg; Uppsala universitet; []
    Keywords : Medical sciences; Allergen; allergy; asthma; dampness; diet; environment; formaldehyde; nitrogen dioxide; plasticizer; schoolchildren; ultrafine particles; MEDICIN OCH VÅRD;

    Abstract : This thesis studied environmental factors in relation to asthma and respiratory symptoms among schoolchildren in two countries. In Sweden, 1014 pupils (5-14 year) in 8 schools participated. Wheeze was reported by 7.8%, current asthma by 5. READ MORE
