An attempt has been made to condense the great volume of literature for many different air pollutants and from many different plant systems. Only those responses that have been reported for several species are emphasized and the discussion is limited to responses obtained with intact plants. The general outline provides a focus; uptake becomes the crucial aspect of whether or not plants are injured by air pollutants. Pollutants must get into the plant to cause injury and the primary portal of entry is through the open stomata. Once into the plant, pollutants alter biochemical reactions, resulting in cell injury and causing economic losses for horticulturists. The authors have developed this outline for the pollutants sulfur dioxide (SO/sub 2/), hydrogen fluoride (HF), ozone (O/sub 3/), nitrogen dioxide (NO/sub 2/), and peroxyacetyl nitrate (PAN), which are the most common and and most damaging gaseous pollutants in the ambient environment.
