Particles from aircraft engines affect airways

In a unique experimental setup, Swiss researchers have investigated the effect of exhaust particles from aircraft turbine engines on human lung cells. The 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. According to the World Health Organization (WHO), seven million people worldwide die because of air pollution every year. For around 20 years, studies have shown that airborne particulate matter negatively affects human health. Now, in addition to already investigated particle sources like emissions from heating systems, industry and road traffic, aircraft turbine engine particle emissions have, in the wake of increasing air traffic, also become more important. As a result, scientific research of the particulate matter from air traffic is important for the development of environmental standards in the aviation sector.
