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.
摘要
测定了主要空气污染物二氧化氮在菜豆（Phaseolus vulgaris（L.））中的吸附速率和代谢命运。通过化学发光监测（15）NO 2 从测试大气中去除，并通过质谱分析植物组织中衍生的氮，直接确定了吸附动力学。吸附过程与（15）NO 2 浓度呈一级关系。几乎所有被吸收的（15）NO 2 都被代谢了。
