  1. 1. Removal of ultrafine particles by intermediate air filters in ventilation systems. Evaluation of performance and analysis of applications.

    University dissertation from Chalmers University of Technology

    Author : Bingbing Shi; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor air quality; ultrafine particles; air cleaning; filter standard; intermediate filter; measurements; modelling; lifetime cost; particle source; health effect;

    Abstract : Epidemiological and toxicological studies demonstrate that ultrafine particles (UFPs) are strongly related with respiratory and cardiovascular diseases and syndromes. One common method to reduce human exposure to particulate air pollution is the use of intermediate class filters (F5-F9 class filters according to EN779:2002). READ MORE

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

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Camilla Andersson; Stockholms universitet.; [2009]
    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; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; tillämpad miljövetenskap; Applied Environmental Science;

    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. 4. Lidar Studies of Tropospheric Aerosols and Clouds

    University dissertation from University of Gothenburg

    Author : Frans Olofson; Göteborgs universitet.; University of Gothenburg.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : An improved description of aerosol and cloud processes is a prerequisite for successful prediction of future climate change. The climate on Earth is controlled by the radiation budget, i.e. the relation between the radiation going into and out from the atmosphere. READ MORE

  5. 5. Performance-based design of ventilation systems. Potential and limitations regarding indoor air quality

    University dissertation from Chalmers University of Technology

    Author : Ragib Kadribegovic; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; indoor air quality; ventilation; prescriptive design; performance-based design; air cleaning; recirculation; energy efficiency;

    Abstract : It has been increasingly common to design for increased ventilation rates above legislative requirements specified in building codes and other norms as the most optimum way to improve indoor air quality. However, this concept has recently been challenged, for example, by studies demonstrating that the emissions or pollution from used traditional particle filters increases proportionally with air flow through the filter.
