Plants are sensitive to air pollutants, and exposure to these harmful gases in the atmosphere results in vegetation injury. Not only do incidents of high air pollution cause visible damage, but also chronic, sublethal levels of air pollutants contribute to the weakening and eventual destruction of a plant's physiological life processes. Both the acute incident and sublethal levels adversely affect the growth, productivity, and quality of vegetation. As with pathogenic diseases, the extent and nature of injury or damage are determined by genetic, climatic, and meteorologic factors as well as by level and duration of exposure to various types of pollutants. The sources and symptoms of plant damage caused by SO/sub 2/, fluorides, ozone, and PAN are discussed.
