In case you didn't go to the Aerotoxic Association link, the CNN in the USA did
a good piece on contaminated bleed air yesterday which was very well explained by their reporter and by Capt Tristan Loraine.
(TwinJock: Life may be a terminal disease, but who knows what inhaling TCP can lead to? To me, breathing even small amounts of a neurotoxin every day at work can't be good for you. And as has been explained in numerous places, just because you're not affected doesn't mean everything's OK - due to individuals' genetic makeup, enzymes etc, not everyone has the same response.)
Not sure Why this has been moved to the cabin crew forum - it can affect anyone in an aircraft.
