  1. 1. Cardiovascular effects of diesel exhaust : mechanistic and interventional studies

    Författare :Magnus Lundbäck; Anders Blomberg; Benoit Nemery; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; diesel exhaust; nitrogen dioxide; endothelin-1; cardiovascular effects; exhaust particle trap; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

    Sammanfattning : Background: Air pollution is associated with negative health effects. Exposure to combustion-derived particulate matter (PM) air pollution has been related to increased incidence of cardiovascular and respiratory morbidity and mortality, specifically in susceptible populations. Ambient particles, with a diameter of less than 2. LÄS MER

  3. 2. Diesel exhaust and wood smoke : mechanisms, inflammation and intervention

    Författare :Ala Muala; Thomas Sandström; Mark W Frampton; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

    Sammanfattning : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. LÄS MER

  4. 3. Acute cardiovascular effects of biofuel exhaust exposure

    Författare :Jon Unosson; Jenny A Bosson; Anders Blomberg; Jeremy P Langrish; Campen Matthew; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular; air pollution; endothelial dyssfunction; arterial stiffness; wood smoke; woodsmoke; biodiesel; RME; biofuel; diesel exhaust;

    Sammanfattning : BackgroundAnthropogenic air pollution is a global health problem estimated to contribute to millions of premature deaths. Exposure to biomass smoke is common due to varying sources, such as wildfires, indoor cooking over open fires, and residential heating from wood stoves. LÄS MER

  5. 4. Volatility and number measurement of diesel engine exhaust particles

    Författare :Hanna Bernemyr; Hans-Erik Ångström; Nigel Clark; KTH; []
    Nyckelord :particle emissions; measuring methods; particle number measurements; dilution; rotating disc diluter; v-TDMA; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. LÄS MER

  7. 5. On the Agglomeration of Particles in Exhaust Gases

    Författare :Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. LÄS MER
