  1. 1. Chemical emissions from building structures emission sources and their impact on indoor air

    Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE

  2. 2. Traffic Emissions of Aerosols

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

    Author : Matthias Vogt; Douglas Nilsson; Eiko Nemitz; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. READ MORE

  3. 3. Emissions of volatile organic compounds from wood

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

    Author : Karin Granström; Bengt Månsson; Ann-Margret Strömvall; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOC; terpenes; drying; wood; emissions; spouted bed; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds.The purpose of this work was (1) to develop a method to establish the amount of emitted substances from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbons, (3) to examine the emissions of monoterpenes during production of pellets, and (4) to examine the natural emissions from forests with an eye to implications for modelling.

  4. 4. Reducing Diesel Engine Emissions - An Experimental Investigation

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

    Author : Arjan Helmantel; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical methods; Soot; Diesel; Emissions; HCCI;

    Abstract : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. READ MORE

  5. 5. Road traffic metals sources and emissions

    University dissertation from Kalmar

    Author : David Hjortenkrans; Bo Bergbäck; Per-Arne Malmqvist; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. READ MORE
