This study evaluated the effects of acidic fog on winter crops of the San Joaquin Valley (alfalfa, broccoli, carrot, onion, potato, and wheat), and spring crops of the South Coast Air Basin (alfalfa, celery, green pepper, strawberry, and tomato). The study also evaluated the interaction between acidic fog and ambient oxidants on the crops of the South Coast. For the spring study, fog at pH 1.68, 2.69, or 7.24 was applied twice weekly to potted plants grown in open top field chambers or air exclusion plots for seven weeks. Fog at pH 1.68 caused necrosis on leaves and fruit of all species. Season long exposure to pH 1.68 fog reduced yield in strawberry, tomato, green pepper, and alfalfa. Species differed widely in their sensitivity to acidic fog.
