Abstract. Jet engine aircraft are ubiquitous and significant sources of atmospheric nanoparticles. Using size-resolved particulate samples collected near a runway of the Narita International Airport, Japan, we clearly demonstrate that organic compounds in the ambient nanoparticles (diameter: <30 nm) were dominated by nearly intact forms of jet engine lubrication oil. This finding provides direct evidence for the importance of unburned lubrication oil as a source of aircraft exhaust nanoparticles and also has an implication for their environmental impacts near airports and in the upper troposphere.

Short summary
Jet engine aircraft are significant sources of atmospheric nanoparticles. Using size-resolved particulate samples collected near a runway of the Narita International Airport, Japan, we clearly demonstrate for the first time that organic compounds in aircraft exhaust nanoparticles (diameter: <30 nm) were dominated by nearly intact forms of jet engine lubrication oil. This finding has an implication for their environmental impacts near airports and in the upper troposphere.
