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?

In cooperation with the Süddeutsche Zeitung:
Occupational Medicine + Fume Events. A Shadow Empire as a Cartel of Silence

One year ago, DokZentrum dealt with the topic „fume events“: the contaminated air in aircraft. We reconstructed how this health problem developed, and that most incidents do not appear in official statistics. This fact alone has a minimizing effect on the problem. However, the truth is: more and more pilots and crew members become unfit to fly due to exposure to toxic fumes, and are unable to work: 

These investigations left questions unanswered: Why isn’t  anyone taking this problem seriously? And why is nothing changing?

Now we have found the answers: it is the sector of  "occupational medicine" which, with its expert opinions, denies practically all connections between incidents, pollutants and subsequent health problems. In practically all cases.  It was the same scenario with asbestos, mercury, dioxin and other dangerous substances. And now it is contaminated cabin air.

The science of occupational medicine has been integrated into the system of "statutory accident insurance". This in turn is financed by the industry, the companies. Result: only 7% of all cases of occupational disability benefits are paid. Occupational medicine provides reliable help: for companies that are not prepared to take better precautionary measures since this is more expensive than compensation for a few cases.

Why isn’t anybody changing this? Because. it is a completely non-transparent system, it is a "realm of shadows". Nobody outside of the system knows about this. Not until 7pm this evening, when this documentation goes online: or alternatively: 

DokZentrum shares its research results with the „Süddeutsche Zeitung“. Tomorrow, Saturday, 26th May, a compact article will be available in the printed weekend edition as a full centre fold: Cartel of Secrecy.

In the future, silence will no longer be possible.  Although the Aerotoxic Logbook has had to take a short break over the last few weeks as a result of extensive research, we will continue to report continuously.
