N2 - A combination of engineering design, stack sampling, environmental monitoring, and biological indicators was used to solve a serious public health problem resulting from a NO2-emitting chemical plant. Indicator plants (Phaseolus vulgaris) were placed at distances of about 600 m from the source in 8 different directions. After 4 days of exposure, necrotic lesions appeared on the mature leaves of the Phaseolus vulgaris plants at all stations. Good correlation between the duration of wind blowing from the source toward the plant site and the extent of injury (percent of injured leaves and percent of leaf area injured) observed after 2 to 3 weeks exposure at this site could be found.
