Aerotoxic Syndrome – Fume Events

Aerotoxic Syndrome is the term given to the illness caused by exposure to contaminated air in jet aircraft. This term was first introduced in a published paper in 1999 by Dr Harry Hoffman (U.S), Professor Chris Winder (AUSTRALIA) and Jean Christophe Balouet PhD (FRANCE):
Aerotoxic Syndrome: Adverse health effects following exposure to jet oil mist during commercial flights”.

How is Aerotoxic Syndrome caused?

A supply of pressurised air is required by humans to sustain life at high altitude. This air is supplied direct from the compressor section of the jet engine and is known as ‘bleed air‘. Unfiltered bleed air is mixed inside the aircraft with recirculated cabin air at a ratio of 50/50. Although the recirculated is subsequently filtered, all of the bleed air which originates from the jet engines is unfiltered.
