Assoc. (Nov. 1949) Now, The Eye Irritation ! . Bye irritation during smog is caused by the combined action of many substances according to the most recent experimental evidence I It no longer seems ilkely that any one pollutant is responsible for the most disagreeable aspect of the dull murk occasionally plaguing many modern cities. In almost no instances during careful tests con ducted in the Smog Chamber at SRI have the characteristic smarting and watering of the eyes been caused by exposure to any single contaminant-' (In the amounts present during smog) known to exist In the Los Angeles air, for Instance. Yet when nine contaminants, making up.a "reconsti tuted" smog, were placed In the Smog Chamber, in actual smog concentra tion, definite eye irritation resulted. Thus it seems valid to con clude that smoggy eye ` irritation v stems .from many , materials . acting jointly. -- Stanford Research Institute
