Abstract
The effects of one-hour inhalation exposures to 0.3-0.6 micrometers H2SO4 and (NH4)2 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 H2SO4 at 194-1364 micrograms/cu m 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 (NH4) SO4 up to 2000 micrograms/cu m had no measurable effect upon resistance, compliance, regional deposition or mucociliary clearance.
