Crop damaging hydrocarbons which produce the same effect as smog are present in automobile exhaust gases. In the presence of ozone, auto exhaust fumes diluted 1:116 produced typical damage to the five smog indicator plants (spinach, sugar beet, bat, endive, alfalfa). Comparison with gasoline indicated that hydrocarbons from automobile exhaust gases are at least equally as effective as gasoline in producing typical smog damage on the five indicator plants. Because of the significance of the findings expressed in this report, the Los Angeles County Air Pollution Control District is continuing investigations to determine the impact of the total contribution of exhaust gases to the air pollution effects found in the community. 19 references, 3 tables.
