Aerotoxic syndrome is a phrase coined by Chris Winder and Jean-Christophe Balouet in 2000, to describe their claims of short- and long-term ill-health effects caused by breathing airliner cabin air which was alleged to have been contaminated to toxic levels (exceeding known, parts per million, safe levels) with atomized engine oils or other chemicals.[1] An assessment by the UK's House of Lords Science and Technology Committee found that claims of health effects were unsubstantiated.[2] An update in 2008 found no significant new evidence.[3] As of 2013 this syndrome is not recognized in medicine.
