Six adult male volunteers were exposed to 0.15ppm ozone and 0.15ppm sulphur dioxide alone, and in combination with intermittent light exercise over a period of two hours. Two of the subjects developed a cough upon inspiring deeply and coughed mildly during forced expiration when exposed to ozone alone or ozone in combination with sulphur dioxide. A significant enhanced decrease in specific airway conductance after exposure to the ozone plus sulphur dioxide mixture was observed in three of the subjects. These results suggest that the effect of the two gases at 0.15ppm was more than simply additive in some subjects when the subjects exercised in the presence of these gases.
