Solution to cabin air contamination looms

Aircraft cabin air contamination, a persistent issue for airlines because their crew and passengers face the risk of consequent neurological harm, may soon be alleviated by advances in chemical science, according to a new scientific paper published in the UK-based Journal of Hazardous Materials.

The study, sponsored by French industrial lubricant manufacturer NYCO, says: “The research underscores the urgency to replace hazardous industrial OPs [organophosphates] due to their documented neurotoxic effects and associated risks.” The study states analysis of OP chemical structures reveals that “one of the identified clusters had a favourable safety profile, which may help identify safer OPs for industrial applications”. Those applications include aero-engine lubricants, which at present are proven to be the source of contaminants released into aircraft air conditioning systems when “fume events” occur. NYCO has, for years, been researching the possibility of producing aero engine lubricants that are as effective as existing ones, but less toxic.

Findings and consequences from the paper, entitled “Organophosphate toxicity patterns: A new approach for assessing organophosphate neurotoxicity”, will be revealed at the 17-18 September 2024 Aircraft Cabin Air Conference at Imperial College, London.

Also to be presented at the conference is the detail of new tests on passengers and crew that can reveal “biomarkers” in their blood proving that they have been exposed to toxins specific to aircraft cabin air contamination, enabling appropriate remedial actions to be taken by those affected.

In terms of mitigation options while the OP risk to airline passengers and crew remains at its present level, also presenting at the conference are Sweden-based CTT on the subject of cabin air humidification and active carbon filters; BASF on dealing with volatile organic compounds and ozone conversion; and PTI Technologies which will reveal its latest bleed air filtration capabilities.

Surly bonds

“Oh I have slipped the surly bonds of earth and danced the skies on laughter-silvered wings…”

You what?

Poet John Gillespie Magee, who wrote this, was a pilot. A long time ago.

Meanwhile for a passenger, flying short haul economy class today (even short-haul business class) is utterly dire. All of it.

From the experience of online booking to being “processed” by the airport, and finally injected – as if hypodermically – via a windowless jetway into a claustrophobic cabin.

A good crew can lift the experience marginally, but the excitement of flying is dead.

The combined ideas of getting airborne and travel to faraway places once had an element of romance. The imagination, given just a little space, could soar. The soul could breathe.

Back at home, the travel brochure still paints sunlit, azure pictures, the airline promises onboard service and a welcome.

Travel reality then suffocates the images. Every aspect of the “service” is individually commoditized and charged for.

Toward the end of October I booked a flight from London Heathrow to Malta, with Air Malta. All the above comments applied. Punctuality was not a problem. But there was more.

There was something totally dead about the trip once the pax were on board. The cabin crew delivered everything, from the safety briefing to the cabin service, as if they were zombies.

The flight deck crew did not make a single announcement at any point. There were no flight progress displays, and zero information was provided about the destination weather and the arrival.

Air Malta, in its current manifestation, is not long for this world, so crew morale was almost certainly a factor. A successor will duly arrive, but any existing crew who are re-employed know they will enjoy less beneficial terms and conditions. Like the employees at their competitors.

Flying is indeed cheap. It has never been cheaper. But it is joyless. For crew and passengers.

You get what you pay for.
