The report reviews the current state of knowledge regarding the health effects of nitrogen oxides, including nitric oxide, nitrogen dioxide, nitrites, nitrates, peroxacyl nitrates, and N-nitrosoamines. A critical review is provided of existing toxicological, human clinical and epidemiological assessment methodologies and data. Special consideration is given to the identification and explanation of the controversial issues surrounding health effects which have been related to ambient levels of NO/sub 2//NO. Evaluation of existing information on the effects of suspended nitrates and airborne nitrosoamines is emphasized. Suggestions are offered for future research programs involving the health effects of nitrogen oxides.
