Health Effects Of Particulate Matter From Aircraft Engines

Aircraft emissions contribute to local and global air pollution. Health effects of particulate matter (PM); from aircraft engines are largely unknown since controlled cell exposures at relevant conditions are challenging. They examined the toxicity of non-volatile PM (nvPM) emissions from a CFM56-7B26 turbofan; the world’s most used aircraft turbine using an unprecedented exposure setup. So…
