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.
