  2. 16. Dynamics of forest soil chemistry

    Author : Mattias Alveteg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; critical loads; regional; recovery; acidification; modelling; SAFE; MAKEDEP; Kemiteknik och kemisk teknologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.

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

    Author : Ragib Kadribegovic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; prescriptive design; indoor air quality; air cleaning; energy efficiency; performance-based design; recirculation;

    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.

  5. 18. An evaluation of sources contributing to urban runoff pollution

    Author : Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. READ MORE

  6. 19. The use of air pollution control residues in landfill covers and for soil stabilization

    Author : Igor Travar; Richard Beaven; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : About 66% of all heat energy generated in Sweden originates from the incineration of municipal solid waste and biofuels such as wood, cardboard and peat. In addition to heat energy, incinerators generate about 1.7 Mt of ashes each year, of which 500 000 t are air pollution control (APC) residues. READ MORE

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

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

    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
