Cabin fume study finds no evidence of danger

A study of cabin fume events conducted by Cranfield University found no evidence that fume events in airliner cabins cause danger to the crew or to passengers. The study, contracted by the United Kingdom’s CAA and the Committee on Toxicity, measured air samples on a series of regular flights on five aircraft types: the BAe 146, Boeing 757, and Airbus A319, A320, and A321. Samples were taken during specific phases of all flights, and anytime fume events occurred (38 such events took place during the program). The samples were analyzed for the presence of volatile or semi-volatile organic compounds, carbon monoxide, and particles. Some neurotoxins were found, but at levels well within acceptable standards for the workplace or the home.
