The purpose of this study was to evaluate pulmonary function changes in dogs acutely exposed to a combination of urban pollutant gases and aerosol particles. The exposure protocol and atmospheres were designed to maximize the possibility for observing interactions by testing a reactive pollutant mixture during exercise and making physiological measurements over the time course of the exposure.The multicomponent mixture included ozone (0.6 ppm), sulfur dioxide (5 ppm), and sulfuric acid aerosol (0.45 mg/m/sup 3/, 0.5..mu.. MMAD). Additional aerosol compounds were catalytic salts, MnSO/sub 4/ (0.2 mg/m/sup 3/,0.5..mu.. MMAD) and Fe/sub 2/(SO/sub 4/)/sub 3/(1.2 mg/m/sup 3/, 0.5..mu.. MMAD). The catalytic ions were present in the multicomponent mixture to promote incorporation of SO/sub 2/ into aerosols and conversion of sulfur IV to sulfur VI compounds. Relative humidity was controlled at 85%. The effects of ozone alone were studied for comparison.
