Indoor air quality study shows aircraft in flight may have lowest particulate levels

If you're wondering about levels of particulate air pollution in all kinds of indoor spaces — those on the ground, and those in the air — bet on the aircraft cabin having the lowest levels of tiny aerosol particles. That's according to a recent study led by assistant professor Nga Lee (Sally) Ng, who has a joint appointment with the School of Earth and Atmospheric Sciences. Delta Air Lines, which supported the study, also featured the research in a press release from the airline published in MarketScreener.
