Aged aircraft exhaust poses a rising threat to human health

Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract.

A University of Basel study found that the oxidative potential of aircraft exhaust particles increases significantly during atmospheric aging, while ship engine emissions remain largely stable, suggesting current air pollution regulations underestimate aviation's true health impact.
