Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment, into the atmosphere. The health effects caused by air pollutants may range from subtle biochemical and physiological changes to difficulty in breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system.

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.
