  1. 1. Air pollution and health – Indicators, trends and impacts

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Henrik Olstrup; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; health; measurements; trends; impacts; mortality; NOx; elemental carbon; AQHI; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : This thesis focuses on some of the limitations and difficulties that exist when it comes to quantifying the human health effects that arise as a result of air pollution exposure. The following four issues are particularly analysed and discussed: 1) The measurement techniques used for carbonaceous particles and their lack of consistency; 2) Do the health risks associated with exposure to PM10 depend on the content of elemental carbon in the aerosol?; 3) Trends in air pollutants and the health effects that arise as a result of changed exposure to the measured pollutants; 4) The associations between the measured concentrations of different air pollutants in Stockholm and the daily number deaths; 5) Air quality indicators and health outcomes as basis for an air quality health index (AQHI).

  2. 2. Regional studies of the optical, chemical and microphysical properties of atmospheric aerosols Radiative impacts and cloud formation

    University dissertation from Stockholm : Meteorologiska institutionen (MISU)

    Author : Admir Créso Targino; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; particles; optical properties; cloud; ice crystals; chemical composition; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap;

    Abstract : Atmospheric particles are ubiquitous in the Earth’s atmosphere and have potential to influence atmospheric chemistry, visibility, global climate and human health, particularly downwind from major pollution sources. The main objective of this thesis was to investigate questions pertaining to the microphysical, chemical and optical properties of aerosol particles by using in situ data collected during four experiments carried out in different regions of the Northern Hemisphere.

  3. 3. Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Patrik Winiger; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Radiocarbon; Air Pollution; Arctic Amplification; Climate Change; Arctic Haze; Atmospheric Transport Modeling; Emission Inventory; Carbon Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation interactions (ari) and aerosol cloud interactions (aci). READ MORE

  4. 4. Source-Receptor Modeling of Air Pollution : Assessment of Source Contributions: Source Characterization and Chemometric Applications

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Emma Hedberg Larsson; Stockholms universitet.; [2007]
    Keywords : Particles; Source-receptor modeling; PMF; Elemental source profiles; Levoglucosan; Wood combustion; Air pollution; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Particles released to the atmosphere from anthropogenic sources affect the Earth’s climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. READ MORE

  5. 5. Development and application of Differential Optical Absorption Spectroscopy (DOAS) for Asian urban air monitoring and atmospheric research

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Yu Yong; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian cities; air pollution; DOAS; free radicals; aerosol; long-path absorption; emission sources; industrial emission; atmospheric chemistry;

    Abstract : Urban air pollution is a serious concern in developing countries and there is a need for qualified measurements of a range of compounds on a nation-wide basis. A suitable potential technique for air monitoring is Differential Optical Absorption Spectroscopy (DOAS). READ MORE
