This report documents the results of three related studies conducted to assess the impact of aircraft emissions of nitrogen oxides NOx and hydrocarbons Hc on air quality. The first study consisted of a field program carried out at OHare International Airport and an associated model development program, the purposes of which were to assess the effect of aircraft NOx emissions on ambient 1-hour concentrations of nitrogen dioxide NO2 and to provide a dispersion model suitable for the prediction of such concentrations. The second study involved the collection and laboratory analysis of samples of hydrocarbons in ambient air contaminated by jet aircraft exhaust, together with a determination of the type and relative amounts of the various hydrocarbons detected. The third study consisted of an analysis, based on available data in the literature, of the potential role of aircraft hydrocarbon emissions in the production of photochemical smog. The available literature dealing with the issue of aircraft contributions to photochemical smog has been reviewed and is discussed. At present, the available information is insufficient to evaluate the effect quantitatively. The requirements for further work that would enable a quantitative evaluation to be made are discussed.
