“Aircraft exhaust particles grow more harmful with age, lab study finds” — what this page in the network covers. Fine particles from aircraft exhaust become more toxic as they age, according to new laboratory research. Scientists found that the oxidative potential—a measure of a particle's ability to cause cellular damage—increases over time after emission. The study, which simulated atmospheric aging, suggests that chemical reactions in the air transform these particles, making them more potent triggers of oxidative stress in the human body. Oxidative stress is linked to inflammation and serious conditions like respiratory and cardiovascular disease.
The findings raise concerns for communities near airports and flight paths, where exposure to aged particles may be higher than previously thought. Researchers emphasize that current air quality models may underestimate health risks from aviation emissions. The work highlights the need for updated regulations and cleaner aircraft technologies.
