2. 1. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

   Author : Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. READ MORE

4. 2. Air pollution in Nairobi slums : sources, levels and lay perceptions

   Author : Kanyiva Muindi; Nawi Ng; Joacim Rocklöv; Elizabeth Kimani-Murage; Marie Thynell; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; perceptions; slums; health impacts; Nairobi; Epidemiology; epidemiologi; folkhälsa; Public health;

   Abstract : BackgroundAir quality in Africa has remained a relatively under-researched field. Most of the African population is dependent on biomass for cooking and heating, with most of the combustion happening in low efficiency stoves in unvented kitchens. READ MORE

6. 4. Source-Receptor Modeling of Air Pollution : Assessment of Source Contributions: Source Characterization and Chemometric Applications

   Author : Emma Hedberg Larsson; Christer Johansson; H.-C. Hansson; Ralf Torgrip; Paulo Artaxo; Stockholms universitet; []
   Keywords : Particles; Source-receptor modeling; PMF; Elemental source profiles; Levoglucosan; Wood combustion; Air pollution; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Particles released to the atmosphere from anthropogenic sources affect the Earth’s climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. READ MORE

7. 5. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide

   Author : David Michael Langhammer; Lars Österlund; Tomas Edvinsson; Gunnar Niklasson; Günther Rupprechter; Uppsala universitet; []
