Nitrogen-15 Dioxide Uptake and Incorporation by <i>Phaseolus vulgaris</i> (L.)

Abstract

The sorption rate and metabolic fate of nitrogen dioxide, a major air pollutant, have been determined for Phaseolus vulgaris (L.). Sorption was determined kinetically by chemiluminescent monitoring of (15)NO(2) removal from the test atmosphere and directly by mass spectrometric analysis of nitrogen derived from the plant tissue. Sorptive processes were first order with respect to (15)NO(2) concentration. Virtually all of the (15)NO(2) taken up was metabolized.
