Toxic Fumes on Airplanes Causing Health Concerns for Passengers
Sometimes, airplanes can have a problem where engine oil leaks into the air that people breathe inside the plane.
This happens because of a system called 'bleed air.'
This air can bring in bad fumes, which can cause headaches and other health problems for passengers and crew.
These fumes often contain carbon monoxide and neurotoxins.
The FAA and airplane companies say they are working to fix the issue.
If you are exposed for a long time, it might affect your brain and nervous system.
Toxic fumes can leak into airplane cabins from engines.
The fumes consist of carbon monoxide and neurotoxins.
Fumes enter the cabin through a design element called 'bleed air'.
Fumes can cause health issues such as headaches and nervous system problems.
The FAA and aircraft manufacturers are aware of the issue.
