The problem has been known since the 1950s - roughly 70 years and nothing has ever been done about it. The air in the cabin is still ‚bled off’ (the engines) in airplanes - with the well-known possible consequences for flight safety and health, in particular that of flight crew. We have the cultural history on 'Flying is safe' and the ongoing problems investigated at www.ansTageslicht.de/cabinair (EN).
Although the cabin air is 50% re-circulated in modern aircraft types, the basic problem remains unsolved. With one exception: the Boeing B787. This is/was also the state of knowledge at the first big conference on this topic in London in September 2017. The presentations can now be viewed here: www.aircraftcabinair.com
There are many reasons why no solutions are found: the targeted influencing of scientific discussions, the airlines’ economic interests, the links between politics and air transport industry and other reasons.
The ‚Aerotoxic Logbook’, launched in January 2017, is a first comprehensive documentation addressing the problem of potentially contaminated cabin air (www.ansTageslicht.de/Kabininenluft - German) and documents what is happening in this area. Or, what is not happening. And why not. This German language blog (www.ansTageslicht.de/ATLB) is now also available in English and can be accessed directly via this permalink: www.ansTageslicht.de/ENATLB. And you should also have a look at www.ansTageslicht.de/fume-event-files - an "ABC" under permanent construction.
With the ‚Aerotoxic Logbook’ we want to achieve international networking, bringing together all initiatives and activities to communicate about this unsolved problem and to initiate solutions. At the same time it is a scientific experiment: What must happen before a problem is addressed?
