Abstract
The ozone concentration for pulmonary and symptom threshold effects in flight attendant surrogates was reported between 0.20-0.30 ppmv [ppm by volume] for a 3 h exposure with intermittent treadmill exercise at 1829 m (MSL) simulated cabin altitude. In sedentary occupants of the in-flight airline cabin, the same protocol was used except for omitting all treadmill exercise. Symptoms were assessed with a standardized questionnaire. Pulmonary function was assessed using standardized quantitative spirometry. Male smoker and nonsmoker airline passenger and cockpit crew surrogates 40-59 yr old were used. Small, but statistically significant displacements occurred in symptoms and in some spirometry parameters. The younger subjects usually appeared more sensitive to ozone than the older subjects. No significant differences appeared between smokers'' and nonsmokers'' responses to ozone exposure. The ozone threshold of these sedentary surrogates under these conditions is right at 0.30 ppmv.
