1. 1. 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

3. 2. 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

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

   Författare :Peter Molnár; Göteborgs universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 5. Acute cardiovascular effects of biofuel exhaust exposure

   Författare :Jon Unosson; Jenny A Bosson; Anders Blomberg; Jeremy P Langrish; Campen Matthew; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular; air pollution; endothelial dyssfunction; arterial stiffness; wood smoke; woodsmoke; biodiesel; RME; biofuel; diesel exhaust;

   Sammanfattning : BackgroundAnthropogenic air pollution is a global health problem estimated to contribute to millions of premature deaths. Exposure to biomass smoke is common due to varying sources, such as wildfires, indoor cooking over open fires, and residential heating from wood stoves. LÄS MER
