Air pollution hurts the body both by directly inflaming and destroying the lung tissue and by weakening the lung's defense against contaminants. Our bodies have ways of protecting us from breathing dist, pollen, and germs. Air pollution is an additional stress on the body's defenses. A sticky substance called mucus lines our air passages. It traps germs and particles before they can enter the lungs. Then cells with tiny, waving hairs called cilia, push the mucus up and out of the body. Air pollution can paralyze or even destroy the cilia. That allows dirt and germs to build up in the mucus, leaving our bodies more vulnerable to disease. Our bodies also defend themselves against pollution by trying to breathe less. Air passages tighten temporarily and breathing becomes harder.
Smoking also harms the body's defenses, making the body more vulnerable to pollution and disease. It can make the effects of air pollution much worse. For more information, go to the American Lung Association of Washington at http://www.alaw.org/air_quality/indoor_air_quality/air_pollution_and_your_hea... .
This is clipped from the film, Smoke Dosage Apparatus (1963) made in Sweden about scientific research on the effects of air pollution inhalation on lungs. The film was made in 1963 for the cigarette company P. Lorillard Co. The entire film is available at the Internet Archives.
