  1. 1. Measuring occupational dust exposure with a passive sampler

    University dissertation from Umeå : Umeå university

    Author : Mariam Shirdel; Umeå universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dust particles; mineral; PM10; PM2.5; respirable fraction; UNC passive aerosol sampler; working environment;

    Abstract : Objectives: In a working environment it is important to measure dust exposure to evaluate possible health issues. Passive sampling could be an alternative to active sampling with pumps when measuring occupational dust exposure. One passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). READ MORE

  2. 2. Elemental composition of fine particles: exposure in the general population and influence from different sources

    University dissertation from Umeå : Umeå university

    Author : Peter Molnár; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; particulate matter; PM2.5; PM1; ultrafine particles; trace elements; personal exposure; X-ray fluorescence XRF ; indoor levels; air mass back trajectories; long-range transport; domestic wood burning;

    Abstract : The general population is exposed to particulate air pollution from many different local and regional sources. Examples of local sources are traffic, biomass burning and resuspended dust, while regional sources are dominated by combustion processes from heating, traffic and industries. READ MORE

  3. 3. Aerosol Particle Sources Affecting the Swedish Air Quality at Urban and Rural Level

    University dissertation from Department of Physics, Lund University

    Author : Adam Kristensson; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wood combustion; traffic; long distance transport; nucleation; urban; background; PM2.5; PM10; source contribution; PIXE; Physics; Environmental technology; Fysik; pollution control; emissions; Aerosol particle; sources; Miljöteknik; kontroll av utsläpp; size distribution; Fysicumarkivet A 2005:Kristensson;

    Abstract : During the last decades anthropogenic aerosol particles have attracted much attention due to their adverse health effects and their influence of climate change, and in Sweden, there are mainly three aerosol sources that affect the air quality; domestic wood combustion, traffic, and long distance transport, which includes new particle formation. This work concerns the characterization of these sources and an estimate of how much they contribute to the aerosol particle number (ToN) and mass concentrations (PM) in Swedish cities and at background locations.
