[Ozone, ventilatory function and bronchial reactivity].
Forty adult hospital workers were followed prospectively in 1989 by monthly assessment of the lung function and bronchial responsiveness to methacholine in a rural region in Switzerland. No correlation was demonstrated between these values and the concentrations of tropospheric ozone. Nevertheless, this is not incompatible with previous studies showing impairment of ventilatory function in subjects exposed to ozone, for several reasons: ozone levels in 1989 were low, the indoor concentrations were lower than outdoors and the volunteers performed little or no physical activity.
