Effects of ozone and brief exercise on specific airway conductance in man.
Four normal male subjects were exposed to 0.9 ppm ozone with exercise for five minutes. Specific airway conductance (Gaw/Vtg) was increased by exercise and decreased by inhalation of ozone in most subjects, but these effects were small. Ozone inhalation with exercise resulted in a highly significant decrease of Gaw/Vtg. It would seem that a peak concentration of 0.9 ppm of ozone for five minutes produces adverse effects when the subject undertakes exxercise in it.
