A potential effect of the combination of ozone and sulfuric acid mist (H2SO4) on respiratory function has been postulated for humans simultaneously exposed to these two pollutants. Nine young men were exposed to 0.25 ppm ozone (O3), 1200-1600 micrograms/m3 sulfuric acid aerosol (H2SO4), and a combination of O3 and H2SO4. During the 2-hr exposures, the subjects exercised (ventilation = 30 L/min) three times for 20 min each. Air temperature was 35 degrees C and relative humidity 83%. Pulmonary function changes after exposure to ozone alone were not expected and were not demonstrated. If a reaction between the combination of O3 and H2SO4 and pulmonary function occurred, pulmonary function responses may have been anticipated following the combination exposure, but no significant changes were seen. It was concluded that the combination of ozone and sulfuric acid aerosol at levels in excess of Threshold Limit Values (TLV) levels do not cause pulmonary dysfunction.
