This report describes results of a survey undertaken at the Western Regional Research Laboratory in cooperation with the University of California at Riverside. Cabbage, carrots, corn, lettuce, strawberries, and tomatoes harvested from plants grown in (1) clean air (carbon-filtered air); (2) clean air fumigated with a low ozone level; and (3) clean air fumigated with a high ozone level were studied. The two ozone levels used (approximately 200 and 350 ppB O/sub 3/) represented levels commonly observed in the air in Southern California in summer and fall. Items determined quantitatively included five vitamins, solids, nitrogen, fiber, ash carbohydrate, and up to nine metals. The metals Ca, Cu, Fe, Pb, Mn, K, Rb, Sr, and Zn were determined using X-ray fluorescence spectroscopy. With the metals significant differences occurred with different plants. The nonmetal nutrients showed that ozone had some effect on the crops. Carotene, vitamin C, thiamine, and riboflavin were studied. This survey indicated that ozone did not have a major and generally deleterious impact on crop composition. It indicated some areas where ozone influenced crop composition. 14 references, 5 tables.
