Abstract

Interest in air pollution injury to native vegetation has been generated with the construction and planned construction of large coal-fired power plants near the coal reserves in the southwest desert areas of the United States. Since information on the effects of SO2 on these native species was not available in the literature, fumigation studies were conducted with portable chambers placed over native species in the field with SO2 and SO2 + NO2. Pollutant concentrations were measured and controlled with instruments located in a mobile laboratory. Each fumigation was of two hours duration and the concentration ranged from 0.5 to 11 ppm SO2 and from 0.1 to 5 ppm NO2. Concentrations of SO2 above 2 ppm were required to cause injury to all but a few of the 87 species studied. Many of the native desert species proved to be highly resistant to injury from these gases.
