Major aerosol pollutant in jet plane emission is Fluorocarbon.
Fluorocarbons are fluorinated carbon chain polymers that are used in an assortment of household and commercial products as waterproofing agents, lubricants, sealants, and leather conditioners.
Aircraft emissions vary with the engine type and the kind of fuel. Aircraft jet engines directly emit aerosol particles and condensable gases such as water vapor (H₂O), sulfuric acid and organic compounds, which lead to the formation of new, liquid (volatile) particles in the early plume by gas-to-particle conversion (nucleation) processes.
