From page 1...
... Particulate emissions from ground vehicles (including GSE and ground access vehicles) , construction activity, and stationary sources are generally well characterized, at least for particle emission mass; emissions from aircraft main engines and APUs much less so.
From page 2...
... 5. Expand current understanding of the health impacts of PM emissions, especially for the fine and ultrafine particles, which are believed to have the most significant impacts on human health.
From page 3...
... isolate individual emission sources, for example, when evaluating the impact of airport operations on nearby communities. It would be a significant benefit to airports if characteristic markers or "fingerprints," based on for example, particle size, mass, composition, or a combination of these, could be defined that were unique to individual sources.
