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

    Författare :Peter Molnár; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Impact of residential wood combustion on urban air quality

    Författare :Patricia Krecl; Christer Johansson; Johan Ström; Tami Bond; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; residential wood combustion; air quality; aerosols; black carbon; polycyclic aromatic hydrocarbons; particulate matter; particle size distributions; source apportionment; positive matrix factorization; compound-specific radiocarbon analysis; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Wood combustion is mainly used in cold regions as a primary or supplemental space heating source in residential areas. In several industrialized countries, there is a renewed interest in residential wood combustion (RWC) as an alternative to fossil fuel and nuclear power consumption. LÄS MER

  4. 3. Particle Emissions from District Heating Units Operating on Solid Biofuels

    Författare :Aneta Wierzbicka; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; particle emissions; biomass combustion;

    Sammanfattning : With the increasing interest in the use of biofuels for heat and energy generation there is a growing concern about emissions from their combustion. It has been shown that biofuel furnaces emit relatively high quantities of particulate matter in comparison to natural gas and light fuel oil furnaces. LÄS MER

  5. 4. Cookstoves, Candles, and Phthalates – Real Time Physicochemical Characterization and Human Exposure to Indoor Aerosols

    Författare :Christina Andersen; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerosol particles; OA; BC; cookstoves; candle emissions; phthalates; human exposure; PAHs;

    Sammanfattning : Exposure to air pollution is associated with adverse health effects in humans, with special concern for exposure to fine particulate matter (PM2.5). The physicochemical properties of aerosols impact the health effects. LÄS MER

  7. 5. The fate and ash transformations of phosphorus in combustion of biomass and sewage sludge

    Författare :Joel Falk; Marcus Öhman; Nils Skoglund; Dan Boström; Franz Winter; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The combustion of phosphorus (P)-rich biomass has a significant potential to increase the stock of biomass resources available for renewable heat and power production. In addition, the P-rich ashes have the potential as a fertilizer and could reduce the need for non-renewable P resources in agriculture. LÄS MER
