www.faa.gov(CO), partially combusted or unburned hydrocarbons (HC), particulate matter (PM), and other trace compounds. Generally, about 10 percent of aircraft pollutant emissions. 7. are emitted close to the surface of the earth (less than 3000 feet above ground level). The remaining 90 percent of aircraft emissions are emitted at altitudes above 3000 feet.

www3.epa.govParticulate matter (PM) is the general term used for a mixture of solid particles and liquid droplets suspended in air. U.S. EPA defines PM 10 as particle matter having a nominal aerodynamic diameter of 10 micrometer ( µm) or less. PM 2.5 is defined as PM less than or equal to 2.5 µm in aerodynamic diameter. In general, “coarse PM” refers ...
