Airports Pollute More Than Skies Above

An investigation has uncovered the presence of harmful ultrafine particles within aircraft cabins, posing a potential health risk to airline passengers. These microscopic particles, invisible to the naked eye and often unregulated, were found in significant concentrations during critical phases of flight.

Researchers discovered that pollution levels were at their peak when planes were boarding and taxiing on the tarmac. These concentrations surpassed the World Health Organization's threshold for high particle levels, although air quality improved once the aircraft reached cruising altitude. A similar pattern was observed on landing, with pollution increasing near airports.

The impact of these ultrafine particles extends beyond the airport environment, with studies showing they spread into neighboring communities. Concentrations measured a kilometer away from major airports were comparable to those found near busy city roads, affecting millions who live and work near flight paths.
