Effects of short-term exposures to sulfuric acid and ammonium sulfate aerosols upon bronchial airway function in the donkey

Journal Article · · Am. Ind. Hyg. Assoc. J.; (United States)
The effects of one-hour inhalation exposures to 0.3 to 0.6 ..mu..m H/sub 2/SO/sub 4/ and (NH/sub 4/)/sub 2/SO/sub 4/ aerosols in the donkey were studied in terms of alterations in pulmonary flow resistance and dynamic compliance, and changes in the regional deposition and tracheobronchial mucociliary clearance of an inert test aerosol. Short-term slowing of clearance followed certain single exposures to H/sub 2/SO/sub 4/ at 194 to 1364 ..mu..g/m/sup 3/ in three of four animals, while two of the four demonstrated a more persistent slowing of their clearance. These exposure levels produced no measurable change in resistance, compliance or regional deposition. Exposures to (NH/sub 4/)SO/sub 4/ up to approximately 2000 ..mu..g/m/sup 3/ had no measurable effect upon resistance, compliance, regional deposition or mucociliary clearance.
