The effects of sulfuric acid particle concentration (mass/volume) and ambient temperatures on pulmonary function of young male nonsmokers were examined. Subjects (n=11) thrice repeated a sequence of 20-min exercise (ventilation approximately 30 liters/min) and 20-min sitting rest. Pre-and postexposure pulmonary function tests (forced vital capacity maneuvers, lung volumes, maximum voluntary ventilation, Raw, TGV, and helium-oxygen FVC) were measured.
