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

    Detta är en avhandling från Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

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

    Sammanfattning : 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. LÄS MER

  5. 5. Health effects of air pollution in Iceland respiratory health in volcanic environments

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Hanne Krage Carlsen; Umeå universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory health; air pollution; volcanic ash; epidemiology; hydrogen sulfide.; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : Air pollution has adverse effects on human health. The respiratory system is the most exposed and short-term changes in air pollution levels have been associated with worsening of asthma symptoms and increased rates of heart attacks and stroke. Air pollution in cities due to traffic is the major concern, as many people are exposed. LÄS MER
