This criteria document focuses on a review and assessment of the effects on human health and welfare of the nitrogen oxides, nitric oxide (NO) and nitrogen dioxide (NO2), and the related compounds, nitrites, nitrates, nitrogenous acids, and nitrosamines. Although the emphasis is on presentation of health and welfare effects data, other scientific data are presented in order to provide a better understanding of these pollutants in the environment. To this end, separate chapters are included which discuss the nitrogen cycle, sources and emissions, atmospheric chemical processes which transform emissions of nitrogen oxides into related airborne compounds, transport and removal processes, measurement methods, and atmospheric concentrations of nitrogenous pollutants.
