This conference examined the effects of aircraft operations on ambient air quality. It has been becoming increasingly apparent that the scales to be considered range from local to regional and that aircraft as a source of emissions have to be distinguished from other airport-related sources such as passenger and ground support vehicles, and stored fuel. The following are among the technical findings of the conference on the pollutants of interest: (1) Hydrocarbons (HC) -- In view of the complex nature of the relationship between HC and the photochemical oxidant problem, it appears that aircraft as a source must be viewed along with other sources in the region; (2) Carbon Monoxide (CO) -- General aviation aircraft appear to make little contribution. With regard to other aircraft, periods and areas of intense activity (ramp and queuing areas, automobile access roadways, vicinity of buildings and terminals) may give rise to 'hot' spots. (3) Nitrogen Oxides (NOx) -- The NOx is emitted as nitric oxide (NO) along the runway. The problem may be quite local and its severity appears to be linked to the levels of ozone in the airport vicinity; and (4) Particles: Particle emissions do not appear to be a problem except for possible effects on visibility around airports.
