During the short-term effect of a mixture of ozone and sulfuric acid aerosol in different combinations, enhancement of toxic effects was found in rats in comparison with the effect of each of the individual components. Enhancement of the toxic effect was found during long-term exposure to a mixture of ozone and sulfuric acid aerosol in concentrations near the threshold concentration. A different species-specific sensitivity was shown in mice and rats with respect to the combined effect of ozone and sulfuric acid aerosol and to each component individually. The above enables one to recommend lowering the magnitude of maximum permissible concentrations of ozone and sulfuric acid aerosol by 2 with their simultaneous presence in the air of production areas.
