Remember - if this is on the ground, it could very well be exhaust from nearby jet engines getting sucked in by the aircraft engine(s). I noticed this just a couple days ago while sitting in a...

And I'm simply point out that if the air being sucked in from outside is contaminated, then the air inside will be similarly contaminated. Any meaningful analysis needs to look at the entire system....
