Thank you Tristan
Keep at it.
In the face of your organisation's (and others') constant and increased pressure, I'd like to think airlines and manufacturers are slowly realising that things have to change wrt Cabin Air Quality. I do know of some airlines who have already swapped out the engine oils they use, who have added better air filters and modified their maintenance/ engine inspection regimes to reduce the likelihood of fume events. There are also some airlines who have fitted detector/warning systems that are allied to better post-fume-event crew checklists, procedures and after-flight medical responses. Whilst they have done this very quietly so as not to embarrass the industry (maybe), it still is a start. Even the ever-increasing presence of the B787 on the world register is 'bio-marker' in itself - and those who fly this ac are immensely impressed by the air quality on board (even if Boeing SAY the concept was (re)introduced for other reasons).
Nonetheless, there is still a long, long way to go and all of the above does nothing for those who were harmed in the past, the recent past, or even those being harmed presently in aircraft/airlines who are slow on the uptake. Furthermore, it beggars belief that the most of the world's regulators are, in the main, still silent (Wake up CAA/FAA/EASA!).
The concerted Bradford Hills approach bears a close resemblance to the events of the 1960s and cigarette-smoking in Europe and America - which sadly took 20+ years to get governments to introduce bans on that 'bad habit' in public - but because of the slow response, many millions died or got sick despite the world getting there eventually. Let's hope that global aviation learns from that and introduces more-quickly the means to prevent airlines from poisoning their own staff and their fare-paying passengers in the pursuit of 'profits over safety' - also airlines would do well to consider compensating those personnel already affected. This might be expensive but probably a lot less so than fighting a deluge of class actions in the courts once the medical evidence exceeds critical mass for frequent-flyers - which is not far off even now.....
Contrary to what David Learmount says, I understand that 'Aerotoxic Syndrome' IS now an accepted medical term in many fields but that it needs to have its profile raised amongst the new generation of healthcare professionals - so when suffers present with symptoms, they can refer them more expeditiously to the appropriate specialists.
Well done and Good luck,
