Swiss team finds particle emissions from aircraft turbine engines at ground-idle induce oxidative stress in bronchial cells

Green Car Congress

In a study on the effect of exhaust particles from aircraft turbine engines on human lung cells, Swiss researchers have found that cells reacted most strongly to particles emitted during ground idling. The study also showed that the cytotoxic effect is only to some extent comparable to that of particles from gasoline and diesel engines.
