In an experiment studying the clearance via the blood of radiolabeled sulfuric acid aerosol in different species, the authors have observed that sulfur from sulfuric acid was rapidly cleared (from 2 to 9 minutes) from the lungs of animals into the blood following inhalation exposure. Sulfate is a normal constituent of the blood and is a normal metabolite of sulfur-containing amino acids, and
