With the aid of wind‐tunnel experimental setup, the possibilities that nitrogen monoxide (NO) is oxidized to nitrogen dioxide (NO 2 ) in various environments were studied, which include indoor, outdoor and darkroom conditions. By comparing their effects, a conclusion can be drawn that NO can be oxidized to NO 2 in indoor environment with a low rate, and micro amount of ozone, propylene and methane can accelerate the reaction: 2NO+ O 2 ·NO 2 . The initial concentration of NO has effect on the oxidation rate. When the initial concentration of NO ranges between 500 and 900 μg/L, natural logarithm of initial rate and natural logarithm of initial concentration have a good linear relation, so do m(1/[NO]) and the time ( t ). Besides mat, the possible oxidation mechanism of indoor NO has also been studied.
