Identification of jet lubrication oil as a major component of aircraft exhaust nanoparticles

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 iphone 13 price dallas nanoparticles (diameters: < 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 rubbermaid 8 gallon trash can as a source of aircraft exhaust nanoparticles and also has an implication for their environmental impacts near airports and in the upper troposphere.
