Research & Science
The science behind cabin air safety.
Understanding the health effects of fume events requires rigorous research. We support and share evidence that informs policy, medical practice, and public awareness.
What we know
Cabin air in most commercial aircraft is drawn from engine compressors (bleed air). When seals fail or fluids leak, contaminants can enter the cabin.
- Tricresyl phosphate (TCP) — found in jet engine oil; known neurotoxin
- Carbon monoxide — from incomplete combustion
- Hydraulic fluid vapors — can cause respiratory and neurological symptoms
- De-icing fluid — ethylene glycol and propylene glycol compounds
Recognized symptoms
Symptoms can appear during or after a flight and may persist for days, weeks, or longer.
If you experience these symptoms after a flight, seek medical attention and mention possible cabin air exposure. Early documentation is important for both treatment and any future claims.
