  2. 1. Towards elimination of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Yannick Desplanques; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne; brake block; brake pad; railway; subway; TEI; wheel–rail; wear; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles from rail transport started in the late 1910s, the high mass concentrations of these particles have prompted concern among researchers interested in air quality. However, effective action has yet to be taken because relevant knowledge is still missing. READ MORE

  4. 2. Cardiovascular disease among professional drivers and subway staff in Stockholm

    Author : Carolina Bigert; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Myocardial infarction; occupation; particles; underground; hematological effects;

    Abstract : Professional drivers are at an increased risk of myocardial infarction (MI), but the underlying causes are not clear. The aims of this thesis were to broaden our understanding of the causal factors involved in this elevated risk of MI in professional drivers, and to study time trends in the incidence of MI in professional drivers.

  5. 3. Measuring Elemental Carbon in Occupational Environments

    Author : Anna Wallén; Hans-Christen Hansson; Göran Lidén; Karine Elihn; Thomas Kuhlbusch; Stockholms universitet; []
    Keywords : Diesel Exhaust Particles; Thermo-Optical Analysis; Black Carbon; Pyrolytic Carbon; Wood Smoke Particles; Water Soluble Organic Compounds; Asphalt Paving Work; Bio Fuels; Subway Aerosol; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Carbonaceous aerosol particles from combustion, such as diesel exhaust particles (DEP), harm human health and affect the Earth’s radiative system.Elemental carbon (EC) has been proposed to be used as a marker of DEP. READ MORE

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

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

    Abstract : 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.

  7. 5. Particularly harmful particles? A study of airborne particles with a focus on genotoxicity and oxidative stress

    Author : Hanna Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : particulate matter; particles; genotoxicity; oxidative stress; DNA damage; inflammation; subway; tire-road; wood;

    Abstract : Today it is well established that particulate matter (PM) cause a wide range of health effects. The underlying mechanisms likely include inflammation, oxidative stress and genotoxicity. There is however a lack of knowledge regarding how particles from different sources contribute to these effects. READ MORE
