To facilitate understanding of test results, this report begins with four primer sections on • PM characteristics, sources, air quality effects, and health consequences; • Hazardous air pollutants; • Field test methodologies; and • Models for the estimation of emissions, air quality effects, and health consequences. These primer sections are followed by a summary of test results and a review of relevant published material.

This more complete dataset will improve estimates of airport contributions computed by air quality models. The primary observations and conclusions from these studies that are of interest to the airport community are • Emissions data at the exhaust nozzle from a subset of engines operating in the commercial fleet have been collected.

The ratio of partially burned HC to lubrication oil depends on engine technology and thrust setting. For certain engines, lubrication oil constitutes up to 90% of the organic PM emitted at high thrust where combustor efficiency is maximized and unburned fuel is at a minimum.

They have yielded data from more relevant engine technologies than had been available previously. The measurement methods developed in these studies provide an excellent foundation for future studies.
