2. 1. Determination of VOC Emissions from Surface Coatings by Environmental Test Chamber Measurements

   Author : Alireza Afshari; Chalmers University of Technology; []
   Keywords : chamber; surface coating; emission rate; measurement; VOC; concentration;

   Abstract : The emitting properties of different building materials are obtained by measurements in environmental chambers of a few established designs. In order to interpret the results from the measurements and to predict the influence on the indoor environment, it is necessary to have a good understanding of the parameters governing the emission process.

4. 2. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

   Author : Per-Olof Larsson; Tillämpad biokemi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

   Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

5. 3. Influence of building envelope on indoor air quality: Field measurements, analysis, and method development related to indoor odors

   Author : Fredrik Domhagen; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material emissions; VOC; odor; ventilation; indoor air quality;

   Abstract : The ventilation system should provide occupants with fresh air while removing excess pollutants from the building. However, increasing ventilation may inadvertently draw more pollutants into the occupant area or prove ineffective in altering emission rates from building materials and furnishings. READ MORE

6. 4. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

   Author : Julia Hammes; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

   Abstract : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

7. 5. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

   Author : Epameinondas Tsiligiannis; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

   Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE
