Nitrogen dioxide is a reddish-orange-brown gas with a
characteristic pungent odor. The partial pressure of NO2 in the
atmosphere restricts it to the gas phase at usual atmospheric
temperatures. It is corrosive and highly oxidizing and may be
physiologically irritating. The presence of nitrogen dioxide in
ambient air has been associated with a variety of respiratory
diseases. NO2 is essential to the production of photo
