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?

Immediately following the end of the International Aircraft Cabin Air Conference held in London on September 17th and 18th, the international Network Aerotoxic Team posted a selection of images. The images offer an overview of the speakers and their subjects.

The conference was the second on the topic of Aircraft Cabin Air Quality. Participants and speakers are mainly the critics and warners who have been pointing out these unsolved problems for a long time. The aviation business, in particular, the airlines and the manufacturers, refused attendance yet again. Only PALL Aerospace and BASF, who both produce filter technologies, presented their products.

Below are the most prominent speakers and their topics, to be viewed on Aerotoxic Team's website:

  • Prof. David MICHAELS, author of the book "Doubt is their Product" (and other publications) with the subject "Chemicals are not innocent until proven guilty".
  • Dr. Daniel DUMALIN / Prof. VYVYAN on nerve damage
  • Susan MICHAELIS PhD: Is this a safety issue? The EASA way
  • Prof. Byron W. JONES on particles and ultrafine particles in cabin air from burnt oil residues
  • Prof. Dieter SCHOLZ from Hamburg on "Flight Mechanics Aircraft Systems". His original presentation among other topics can be found on his website.

Updates to follow as they arrive.

The London Economic (TLE): New Article On Toxic Substances In Flying

Once again, the TLE discusses the problem concerning in particular  the cocktail of chemical substances identified in the cabin air by EASA themselves, respectively in a study commissioned by EASA.

„What toxins are we being exposed to in air travel?“ is the headline of the article written by Bearnairdine BEAUMONT, who is in charge of the network.

Literature Study on Cabin Air by the BDLI In 2017 and 2015: Today, two respectively four years later.

We inquired about the outcome a third time on June 17th. And again, we didn't get any answer although the literature evaluation was adequately carried out by the German Aerospace Center (DLR) as the contractor and handed over to the BDLI.

Now we wanted to investigate by telephone, but we were unable to get through to the press office. A request we left on their a.m. for a call back has been ignored.

We now give up,  with the conviction that the results of the entire literature (FuSe study - Fume and Smell Events) concerning the problem of potentially contaminated cabin air did not have the desired outcome for the aviation business. There is no other explanation for BDLI’s behaviour.

Toxicological Cocktail Effects in Cabin Air

The result of a study published ten years ago carried out on behalf of the FAA: "Aerospace Toxicology: An Overview" states that "individual substances may not be particularly toxic" - but:

 "It is well established that the toxicity of individual substances differs from their mixture(s). Such a difference would be because of the interactive effects of chemicals present in the mixture(s). Thus, the overall toxicity would be the result of additive, potentiation, synergistic, and/or antagonistic type of interaction(s) among chemicals present in the mixtures in relation to the toxic effects exerted by the individual components of the chemical mixtures."

Precisely this is either denied or minimized in this country. Moreover, not investigated in any of the cases.

The researcher also evaluated a British study in which the ducts of the bleed air to the air-conditioning system were examined. The substances inside easily crumbled off, containing: aluminium, silicon, carbon, sulphur, phosphorus. Substances that  (can) impregnate the cabin air via the air conditioning system.

"This has nothing to do with flight operations."

Someone who knows: André FERNITZ, who has been working on the ground at Tegel Airport for thirty years. He describes the daily chaos that reigns there. Not only because the airport is much too small, but also because everything has to become cheaper and cheaper. At some point the capacity is overstretched but everything still has to function reasonably well with detrimental effects on the staff.

André FERNITZ also attended the "Fume Event Consultation Clinic" in Göttingen when it still existed. He too had residues of the engine oils in his blood and urine.

His report was published in the Berliner Tagesspiegel - "Report from The Runway".
