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.
