Natural exposure to smog has caused scarring in the lungs of laboratory animals, and inhalation of sulphur-dioxide fumes produces "airways resistance" (inhibited replenishment of the blood's oxygen supply) in both guinea pigs and humans. In London, where the word smog originated, chronic bronchitis-emphysema, an irreversible pulmonary disorder that can cause eventual heart failure, is now the third biggest killer (behind heart disease and cancer) of men over 45, and British doctors attribute its rapid rise to polluted air. Recent samplings of London smog have revealed dangerous concentrations (300 to 400 parts per million...
LUNG DISEASE. In addition to an overall increase reported in the breathing disorder known as pulmonary emphysema, an apparently new form has been described in the last few years, said Manhattan's No-belman Dickinson W.
