Abstract
Cardiopulmonary and metabolic responses of 20 adult males (age 19-29) before, during and after a 2-hour exposure to either filtered air or 0.50 ppm ozone under four ambient conditions (25C, 45% rh; 31C, 85% rh; 35C, 40% rh; 40C, 50% rh) were determined. Exercise at 40% of the individual's V02 max was performed from 60-90 min of exposure. There were no cardiovascular changes due to ozone exposure but heart rate increased and stroke volume decreased with increasing heat stress. Rectal, mean body, and mean skin temperature also increased. There was a decrease in vital capacity and total lung capacity due primarily to a reduction of inspiratory capacity following ozone exposure. The combination of heat stress and ozone exposure resulted in significantly greater impairment of pulmonary function. The trachial-bronchial irritation caused by ozone reduces the vital capacity and maximum expiratory flow and this effect is more pronounced when the ozone exposure occurs in a hot environment.
