The Aerotoxic Logbook (ATLB) in English (EN)

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 (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:  

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 ( - German) and documents what is happening in this area.  Or, what is not happening. And why not. This German language blog ( is now also available in English and can be accessed directly via this permalink:

The information we collect in German is translated by Bearnairdine BEAUMONT who operates the network  and the blog

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?

Fume Events + "Commission for the Evaluation of Poisonings" at the Federal Institute for Risk Assessment (BfR)

This commission, consisting of 15-plus experts who all deal with poisoning and toxicological issues, ‚intensively discussed’ such a fume event from November 2012 – as mentioned in the protocol position ‚Top 13’ > ’News’. Background: a doctor felt obliged to report an incident to this commission, during which, in his opinion,  a ‚poisoning’ could not be ruled out. In cases of poisonings doctors are actually obliged to do so.

The incident in question was one of the most dangerous incidents happening regarding fume events: On December 19th 2010, the two pilots of a Germanwings Airbus were surprised by a fume event during their landing approach to Cologne/Bonn airport and were barely able to bring the 142-passenger aircraft to the ground. The co-pilot had to be suspended from flying for more than half a year, the captain was fit to fly again after just a few days. The pilots’ flight reports are a dramatic read; they can be found with further information here

The experts had apparently little concrete information but, according to the protocol were nevertheless able to assess a "causality as questionable due to the lack of toxicological analyses".

This prompted us to ask the commissioners whether they would be interested in more detailed information, specifically the flight reports of the two pilots. None of the commissioners replied to our first circular mail sent to everyone on April 11th. We sent a second mail on May 15th. Again: no feedback. Only one of the members let us know that we would receive an answer from the CEO.

Now we have yet again, sent another email on June 27th – to both the Managing Director Dr. Herbert DESEL and all commissioners with the two flight reports - to make sure this issue doesn't fall in between the cracks. We have also let everyone else know about it.

Now we will keep an eye on what happens in this commission. And we will document the progress .
