  1. 1. Respiratory effects of particulate matter air pollution : studies on diesel exhaust, road tunnel, subway and wood smoke exposure in human subjects

    Författare :Maria Sehlstedt; Sandström Thomas; Jamshid Pourazar; Anders Bucht; Steffen Loft; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Airway inflammation; antioxidant; bronchoscopy; detoxification; immunohistochemistry; particulate matter; Environmental medicine; Miljömedicin;

    Sammanfattning : Background: Ambient air pollution is associated with adverse health effects, but the sources and components, which cause these effects is still incompletely understood. The aim of this thesis was to investigate the pulmonary effects of a variety of common air pollutants, including diesel exhaust, biomass smoke, and road tunnel and subway station environments.

  3. 2. Exposure to particulate matter and the related health impacts in major Estonian cities

    Författare :Hans Orru; Bertil Forsberg; Eda Merisalu; Marko Kaasik; Per-Inge Grennfelt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Particulate matter; traffic; health impact assessment; cardiopulmonary; Environmental medicine; Miljömedicin; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Particulate matter (PM) is one of the most studied and problematic pollutants due to its toxicity and relati­vely high concentrations. This thesis aims to clarify the main sources and exposures of PM in Tallinn and Tartu, study the associations with health effects, and estimate the extent of those effects with health impact assessment (HIA).

  4. 3. Particulate and gaseous emissions from residential biomass combustion

    Författare :Christoffer Boman; Anders Nordin; Ingwald Obernberger; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; aerosols; air pollution; emissions; fuel pellets; residential biomass combustion; inorganic characterization; incomplete combustion; particulate matter; polycyclic aromatic hydrocarbons; trace elements; Kemi; Chemistry; Kemi;

    Sammanfattning : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. LÄS MER

  5. 4. Airborne particulate matter in a Sub-Saharan Africa city: Nairobi, Kenya, and at an Equatorial high altitude site: Mount Kenya

    Författare :Samuel Mwaniki Gaita; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray Fluorescence XRF ; Particle Induced X-ray Emission PIXE ; Particulate matter pollutants; Source apportionment; sub-Saharan Africa; Deposition fractions; High- altitude; Free troposphere; Spatial distribution;

    Sammanfattning : In Sub-Saharan Africa (SSA), air quality is gravely understudied despite the existing influential factors such a rapid urbanization and population growth that negatively affect the environment. Majority of urban areas in SSA face challenges that include lack of social services, poor infrastructure development, exponential increase of second-hand vehicles and extensive use of biomass-based fuel for energy needs.
