A total of 18 human subjects were exposed to ambient air for four hours on the first day of exposure and to four hours of 100 micrograms/cu. m. (0.033 micromole) sulfuric acid aerosol exposed to four hours of ambient air on both exposure days. Six biochemical blood parameters were measured pre and post exposure: glutathione, lysozyme, glutathione reductase, serum glutamic oxaloacetic acid transaminase, serum vitamin E and 2,3-diphosphoglyceric acid. The results indicate no significant effect of one four hour exposure of humans to sulfuric acid aerosol (100 micrograms/cu. m.). One significant effect did occur indicating an increase in glutathione reductase post exposure for both the control group and acid group. This report covers a period from October 23, 1978, to December 15, 1978, and work was completed as of May 1, 1979.
