Oxides of Nitrogen: Their Formation and Control in Stationary Sources

Over the last fifty years, a major concern of environmentalists, health care providers, national governments, and international organizations has been the unhealthy and destructive effects of air pollution. In this regard, much attention has the unhealthy and destructive effects of air pollution. In this regard, much attention has been given to a primary pollutant of air - oxides of nitrogen NOx. The two most important oxides of nitrogen with respect to pollution are nitric oxide NO and nitrogen dioxide NO2. In the atmosphere, elevated concentrations of these gases contribute to the greenhouse effect and ozone depletion. In addition, they foster the formation of acid rain and photochemical smog. Lastly, not only do NOx contribute directly to these atmospheric reactions, but they also participate in the production of secondary pollutants which have similar effects.
