Description: One-year-old yellow-poplar seedlings were treated with acid mist at pH 2.5, 3.5, 4.5, and 5.5 either alone or in combination with 0.1 ppm 03, S02, and NO2 or NO2 plus S02. After 4 and 8 weeks of treatment, height, leaf area, and leaf and new shoot weight were determined and growth analysis variables calculated. Height, leaf area, and dry weight decreased with increasing acidity in seedlings treated with acid mist alone. Similar, but smaller reductions occurred in seedlings treated with SO2 and acid mist, but no differences were found in seedlings fumigated with NO2, NO2 plus SO2, or ozone and acid mist. Further studies using different combinations of pollutants and acid mist must be conducted before their apparent interactions can be more accurately assessed.
