[Acute effects of the natural atmospheric ozone exposure on lung function of clinically normal smokers and non-smokers].

The influence of moderate ambient ozone exposure on spirometric lung function and bronchial responsiveness was analyzed in 13 healthy adult nonsmokers and 11 asymptomatic smokers. The study was divided into an initial investigation at low atmospheric ozone concentrations of about 80 (range 68-102) micrograms/m3 and a subsequent similar testing at moderately elevated ozone concentrations above 140 (range 145-205) micrograms/m3. Overall there was a slight but significant impairment in forced expiratory volumes (p less than 0.
