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?

Commission's response to BfR's poisoning assessment

At the end of June we reported, that six years ago this panel of experts had dealt with the topic of fume events (view entry 27th June) but that they had shelved the topic - after "intensive discussions".

This was a reason for us to ask whether the commissions' members would be interested in more detailed information about the close crash in question at Cologne-Bonn airport, in particular regarding  the two pilots' flight reports (see Lufthansa subsidiary Germanwings: 19 December 2010). We had just sent these notes to everyone.

The commission's management now replied: "We will take these into account in our case evaluation and if new toxicological findings are available, we will discuss the facts again at the BfR Commission 'Assessment of Poisoning' meeting."

We will now ask how the commission how they intend to find the "existence of new toxicological findings". Whether they just want to wait for them, or whether they will ask specific questions,  or do research and if so, how exactly. Or whether they would like to commission expertises themselves.

No matter how:  We are staying on the ball.

BG Verkehr at the 10th Commercial Pilots' Day

As we now know, BG Verkehr offered a new presentation about  "Fume events in aircraft, the problems as seen from BG's standpoint",  to be viewed on YouTube, but suddenly offline.

The head of the Department for Prevention, Dr. Jörg HEDTMANN reports little news, but confirms that BG Verkehr now recognises such incidents as "occupational accidents". However, they do not consider from their point of view,  the possible long-term health consequences. Reason: One sticks to the "commonly known school of thought"  (34th minute into the video recording).

Since we - so far - do not know any "common school of thought" regarding this problem (at least none that should be taken seriously), we asked Mr. HEDTMANN which experts' names he associates with the "common school of thought". We made this request on 29th July.

We will report when we receive the answer.

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 .

The translations into English are making progress

Bearnairdine BEAUMONT has translated two more chapters into English at

The latter can also be downloaded as a PDF file intended for the worst case scenario, that you know what to do. But, there are also general tips and advice about what you can do if you want to help change a couple of things.

Lufthansa - BG Verkehr und Laboratory Technician ROSENBERGER: a perpetuum mobile

How industrially controlled research in connection with cabin air functions in Germany, is now also available as a graphic. LH finances BG Verkehr (as do others) on the one hand , on the other hand also the research (as do others) at the Hannover Medical School MHH. They can rely on Wolfgang ROSENBERGER’s results, to which Lufthansa themselves and BG Verkehr regularly refer, for example, in their refusal notices concerning applications for the recognition of the consequential health damages after fume events.

ROSENBERGER - respectively his former boss, who is now retired - works (as do others) in the spirit of the VALENTIN School of Erlangen, now in the fourth generation. (more here: Its outstanding characteristic is - and always has been - its openly demonstrated closeness to the professional occupational liability associations.
