Under the auspices of the Selby Commission, experiments were performed to determine the effects of simulated smelter smoke on the growth of barley. Barley was chosen because it is one of the most sensitive cultivated plants. The experiments were planned to furnish information upon the amount of visible injury caused by definite concentrations of sulfur dioxide acting during definite lengths of time. In addition, the effect of injuries upon the total growth and ultimate yield of the crop and the fertility of the seeds were investigated. An attempt was also made to determine the existence of invisible injuries and the extent to which they occur. Results indicated that 5 ppm of sulfur dioxide with a humidity of 40 applied for 1 hour continuously produces very acute injuries which kill the plant. However, when sulfur dioxide was applied for 10 minutes during each of 6 consecutive days, much less injury was produced.
