What is arguably the fastest means of transportation may not be the safest as recent research shows that the air in aeroplane cabins can be contaminated by oil and engine related leakages.

A study of more than 200 cabin crew found a clear link between contaminated air and ill health.

Researchers from Stirling University found a clear pattern of acute and chronic symptoms, ranging from headaches and dizziness to breathing and vision problems.

Dr Susan Michaelis, of the university’s occupational and environmental health research group, said: “This research provides very significant findings relevant to all aircraft workers and passengers globally.

“There is a clear cause-and-effect relationship linking health effects to a design feature that allows the aircraft air supply to become contaminated by engine oils and other fluids in normal flight.

“This is a clear occupational and public health issue with direct flight-safety consequences.”

The study, published in the World Health Organisation journal Public Health Panorama, is the first of its kind to look in-depth at the health of aircrew.

Scientists conducted two separate reviews of flight attendant safety, examining the circumstances and symptoms of working in a pressurised air environments.

One test looked at pilots’ health and found that 88 per cent were aware of exposure to contaminated air.

Almost 65 per cent reported specific health problems while 13 per cent had died or experienced chronic ill health.

The other tests looked at specific oil leaks.

It found 80 per cent involved toxic fumes and all of the events took place when the aircraft was preparing for, or in flight.

Two thirds of the incidents involved further reports of fumes both before and after the incident.

A further 93 per cent involved symptoms ranging from in-flight impairment such as dizziness and headaches to incapacitation and almost 75 per cent included adverse symptoms in more than one crew member.

There were anywhere between 10 and 23 different symptoms reported in about half of the events.

Vyvyan Howard, professor of pathology and toxicology at the University of Ulster, added: “What we are seeing here is aircraft crew being repeatedly exposed to low levels of hazardous contaminants from the engine oils in bleed air, and to a lesser extent this also applies to frequent flyers.

“We know from a large body of toxicological scientific evidence that such an exposure pattern can cause harm and, in my opinion, explains why aircrew are more susceptible than average to associated illness.

“However, exposure to this complex mixture should be avoided also for passengers, susceptible individuals and the unborn.”

More than 3.5 billion passengers and 500,000 aircrew were exposed to low levels of engine oils in 2015, according to Stirling University.

Unfiltered breathing air is supplied to aeroplane cabins via the engine compressor.

    I agree that the cabin air may be harmful because its unfiltered oersay like no open windows so the getms circulating until they filter thru the vents is unsafe and should get tended to asap in my opinion
