  4. 22. Modelling as a Tool to Evaluate Continuously Measured Concentration Value of Gaseous Indoor Air Pollutants

    Author : Martin Kraenzmer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NO2; modeling; TVOC; modelling; indoor air; pollutants; continuous monitoring; NOx; VOC; NO; O3; continuous measurement; CO; CO2;

    Abstract : Results from studies of air quality in buildings are often difficult to interpret and evaluate and, in order to avoid erroneous conclusions, special evaluating tools may be needed. Modelling in various forms can be used as a method of evaluating measured values from such investigations. READ MORE

  5. 23. Application of Infrared and UV-Visible Remote Sensing Techniques for Studying the Stratosphere and for Estimating Antrophogenic Emissions

    Author : Johan Mellqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stratospheric ozone; temperature dependence; non linearity; FTIR; VOC; flue gas; DOAS; long path FTIR; fugitive emissions;

    Abstract : Infrared and UV/visible broadband absorption techniques have been used in three applications related to environmental research and atmospheric science. The techniques are based on measuring the attenuation of light by the atmosphere in the infrared and UV/visible region, and since a very large number of species absorb light in these wavelength regions, the techniques studied allow the measurement of several species simultaneously.

  6. 24. Physical properties and processes of secondary organic aerosol and its constituents

    Author : Kent Salo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

    Abstract : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. READ MORE

  7. 25. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

    Abstract : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. READ MORE
