Inhaling Diesel Fumes Suppresses Immune Response
Researchers have duplicated the typical diesel-fume exposure of people living in the cities to lab rats and have determined that soot particles from diesel exhaust reduces the immune system’s capacity to fend off infection.
Bacteria survived for longer than a week in the lungs of diesel-exposed animals than those that has only breathed clean air.
Heart and Lung Disease Linked to Polluted Air
Most of the blood in the body moves via arteries and veins, but much smaller vessels called arterioles are responsible delivering blood to the capillaries in tissue. This flow is regulated by the arteriole’s ability to continually constrict or dilate. Animal experiments indicate that breathing soot and other airborne particles compromises the arterioles’ capacity to dilate. In the last decade there have been many studies that have linked both short-term and long-term exposure of air pollution created from fossil fuels to increased morbidity and mortality of cardiovascular diseases in general populations as well as been similarly linked to altered lung function and lung cancer.
