On the relation between the indoor and outdoor concentrations of nitrogen oxides
Simultaneous measurements were made of the concentrations of NO, NO2, and CO inside and outside of a building. The building is located in the Los Angeles area, which is heavily polluted by photochemical smog, and the experiments were conducted at a time of the year when the pollutants in question tend to be high. The results show that there is a direct relationship between the inside and outside concentrations, and that the phase lag between the concentrations depends principally on the ratio of the building volume to the ventilation rate. Although the outside concentrations of the pollutants in question did not follow the same pattern every day, peak concentrations seemed to be related to "rish-hour" traffic. By reducing ventilation rates during these periods, it may be possible to reduce the concentration peaks inside of the building. The results support the belief that NO and O3 do not co-exist indoors except in very small quantities.
