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

    Author : Uve Matson; Chalmers tekniska högskola; []
    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

  4. 7. Experimental Determination of the Deposition of Aerosol Particles in the Human Respiratory Tract

    Author : Jakob Löndahl; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; deposition; respiratory tract; health; air pollution; aerosol particle; ultrafine particles; lung; Fysicumarkivet A:000;

    Abstract : BACKGROUND: Aerosol particles have, since the antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution cause at least 100,000 deaths in Europe each year, whereof 5,000 in Sweden. READ MORE

  5. 8. Elemental composition of fine particles: exposure in the general population and influence from different sources

    Author : Peter Molnár; Göteborgs universitet; []
    Keywords : particulate matter; PM2.5; PM1; ultrafine particles; trace elements; personal exposure; X-ray fluorescence XRF ; indoor levels; air mass back trajectories; long-range transport; domestic wood burning;

    Abstract : The general population is exposed to particulate air pollution from many different local and regional sources. Examples of local sources are traffic, biomass burning and resuspended dust, while regional sources are dominated by combustion processes from heating, traffic and industries. READ MORE

  7. 10. Novel Methods for Sampling, Characterization and Analysis of Airborne Street Particles in a Health Perspective

    Author : Ali Reza Nosratabadi; Anders Ljungman; Per Leandersson; Helen Karlsson; Peter Molnár; Henrik Kylin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fine; Coarse; wear particles; health; Lead; Cadmium; Brake wear particles; Endotoxin; Interleukins; TEOM; IPRL;

    Abstract : Over the last decades, there has been much attention on air quality, especially in urban environments. A significant factor effecting the air quality in the urban environment is airborne particulate matter (PM). Long-term exposure to PM causes increased risk for heart disease, decreased lung function, exacerbation of asthma, and lung cancer. READ MORE
