Horstman, D., W. McConnell, L. Folinsbee, S. Abdul-Salaam, AND P. Ives. CHANGES IN PULMONARY FUNCTION AND AIRWAY REACTIVITY DUE TO PROLONGED EXPOSURE TO TYPICAL AMBIENT OZONE (O3) LEVELS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/D-88/103 (NTIS PB88211891).
Description:
Daily ambient ozone levels between 0.08 and 0.12 ppm for periods exceeding 6 hours often occur in many urban, suburban, and rural areas of the United States and Europe. Substantial decrements in pulmonary functions, moderate to severe respiratory symptoms, and increased airway reactivity have been observed in young men performing moderate to heavy exercise. The study evaluates pulmonary responses of 22 healthy nonsmoking males, resulting from exposures to 0.08, 0.10, and 0.12 ppm ozone.
