Nitrogen Dioxide Poisoning

Comparison of permeation devices and nitrite ion as standards for the colorimetric determination of nitrogen dioxide

“…His analyses showed that 1 mole of nitrogen dioxide was equivalent to 0.72 mole of nitrite ion. Since that time, values of the stoichiometric factor ranging from 0.5 to 1.00 have been reported (Gill, 1960;Kooiker, Schuman, et a!., 1963;Saltzman and Wartburg, 1965;Shaw, 1967;Stratmann and Buck, 1966). Buck and Stratmann (1967) maintain that the stoichiometric factor varies with concentration and approaches 1 at levels of N02 comparable to that found in the atmosphere.…”
