  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. A study of airborne wear particles from automotive disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Werner Österle; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Nanoparticles; Cellular automaton; Mechanical engineering; Maskinteknik;

    Abstract : During braking, both the disc and pads in disc brakes are worn. Since disc brakes are not sealed,some of the wear particles generated can become airborne. READ MORE

  5. 3. Characterisation of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Mats Gustafsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne; railway; brake; block; Other engineering mechanics; Övrig teknisk mekanik; SRA - Transport; SRA - Transport; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality.

  6. 4. Novel Methods for Sampling, Characterization and Analysis of Airborne Street Particles in a Health Perspective

    Author : Ali Reza Nosratabadi; Anders Ljungman; Per Leandersson; Helen Karlsson; Peter Molnár; Henrik Kylin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fine; Coarse; wear particles; health; Lead; Cadmium; Brake wear particles; Endotoxin; Interleukins; TEOM; IPRL;

    Abstract : Over the last decades, there has been much attention on air quality, especially in urban environments. A significant factor effecting the air quality in the urban environment is airborne particulate matter (PM). Long-term exposure to PM causes increased risk for heart disease, decreased lung function, exacerbation of asthma, and lung cancer. READ MORE

  7. 5. Towards a simulation methodology for prediction of airborne wear particles from disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Jens Wahlström; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Particle coefficient; Friction; Mechanical engineering; Maskinteknik;

    Abstract : During braking, both the rotor and the pads in disc brakes are worn. Since disc brakes are not sealed, some of the wear particles generated can become airborne. READ MORE
