A total of 20 human subjects were exposed to 100 micrograms/cu m (0.033 uM) sulfuric acid aerosol (0.5 micrometers mean mass diameter) for four hours per day for two consecutive days. A total of 17 human subjects were exposed to four hours of ambient air on both exposure days. The subjects were at rest during both exposures. Seven biochemical blood parameters were measured pre and post exposure and 20 hours after the second exposure: serum glutathione, red blood cell glutathione reductase, red blood cell glucose-6-phosphate dehydrogenase, lysozyme, serum glutamic oxaloacetic acid transaminase, serum vitamin E and 2,3-diphosphoglycerate. The results indicate no significant response in any of the seven biochemical blood parameters measured.
