This sort of stuff is bleeding heart b*llocks, and opens the door to those seeking another quick buck in compensation claims.
Having flown for 38 years (not all pressurised commercial stuff) I have not suffered in the slightest with all this crap about,
Oil lubricants leaking from aircraft engines and APU’s into bleed air systems has remained an inadequately addressed problem for over 25 years
If there was such a world-wide serious problem, then perhaps such constant and prolonged exposure would see pilots and cabin-staff littering grave yards having died of horrible respiratory problems - there is NO PROOF over the 25 years these folk are talking about that,
Industry has accepted crews and passengers being exposed to contaminated air

Another red-herring.........
Recent medical research has shown that long term repeated exposure to low levels of OPs will cause brain cell death.

I'm with Old King Cole in this, and concur with his views.
IF it is a problem, then it is very minor one and falls in with being alive on this earth - it's a big risk the minute you get out of bed.
Scaremungering is a sustainable hobby now.
