This explains jet lag, or at least a good portion of it. I always attributed jet lag to the radiation exposure from being so close to the sun and all the EMFs in the sky. My husband won’t eat before he gets on a flight because he will throw up afterwards.

We are exposed to so much crap. It’s not a mystery why there is so much chronic disease. It’s actually a small wonder why we aren’t all sick…

Wondering why this doesn't happen to all those pilots and elites flying around every day to their events......

Well, this explains why I always get sick after I fly.

My theory is that low levels of this are common.

Air supplies for forced-air respirators (for working in hazardous atmospheres) are REQUIRED to be from oil-less compressors for this reason.

You wonder if some sort of inexpensive mask might help.

Aircraft could probably be retrofitted with replaceable filters in their air ducts to prevent hazardous vapors from entering the occupied areas of the plane.

A reader just contacted me and said he routinely takes a carbon monoxide monitor on every flight but has never detected a problem.

Yes. Something suitable for organic vapors would be relatively cheap and effective. Many paint stores stock them.

The source of the air would be the same regardless of how it is compressed to cabin pressures.

According to everything I have read or been told by my aviator friends, the same compressor that compresses the air for the engine does so for the cabin. If the olfactory senses of pilots are so poor that they can't smell VOCs, they should be weeded out in their twice annual physicals.

"Jet engines require synthetic oils for lubrication. These oils contain ingredients such as tricresyl phosphate (TCP or TOCP), an organophosphate, which can be toxic to humans but only in quantities much larger than are found in aviation engine oil." wikipedia.org/wiki/Aerotoxic_syndrome FWIW

The folks in the oilfield have H2S sensors that usually alert (so I'm told) before humans can smell it. Since ToCP poisoning seems more likely than H2S, due to H2S's well-known smell, maybe the development of an ToCP sensor and/or deployment of one in every aircraft having the possibility of it getting into the passenger space would be a wise course.

Thanks for this timely information. I had only a glimmer of an idea about it.

I'd like to add a bit of background on the mercury-amalgam subject. There is a fantastic book - Root Canal Coverup - by George Meinig, D.D.S. - published in 1994. He was a founder of the American Association of Endodontists and had performed the procedure many times in his career. When a fellow named Hal Huggins encountered the meticulous 25-year root-canal research of Dr. Westin Price, he passed it along to George Meinig. His book is a thorough review (with pictures) of the whole potato, including a penetrating review of the kind of science that existed in Dr. Price's day. Dr. Price also had many illustrious collaborators over the years.

Thanks again

Many time just after engine startup, I detected a strong whiff of kerosene smell permeating the cabin. For those that do not know jet fuel is essentially kerosene. For high altitude flying and because of the very cold air outside the aircraft, additives are put in the jet fuel to keep it from turning into jelly. This could be part of the issue as well.

One fuel additive I researched years ago is ethylene dibromide (EDB) also known as

1,2-dibromoethane. The additive was used between 1953 to late 1975 in AvGas and JP-4.

Based on historical Air Force fuel usage, AvGas containing EDB as a lead scavenger would have been in use from approximately the 1940s to 1975. EDB is a suspected human carcinogen (1) that was historically added to leaded fuels to prevent the build-up of lead oxide deposits in engines, including aircraft engines.

There was a fuel pipeline leak at Kirtland AFB over many years (2) from 1953 to late 1975.

The fuel was AvGas and JP-4 at Kirtland AFB was phased out in 1975 and 1993.

A fuel additive that many are familiar with was an oxygenate for gasoline called MTBE. MTBE groundwater contamination was almost ubiquitous in all States. I believe only Mississippi was spared groundwater contamination from MTBE because it was never added to gasoline because MS had nonnonattainment areas (3).

All jet engine fuels contain additives but I have not kept up these. I spent a lot of time in from 2012 to 2020 researching PFAS contamination but that's another story.

I'm asthmatic & I used to suffer mild anxiety riding in my missus car because before I met her I'd not known many other people in SW London who drove or needed to, & as such I rode about on my bicycle, on the buses, trains & tubes, & on foot.

So for awhile, driving about in the missus car made me slightly anxious & I'd always need my inhaler after a short while.

But as time went by I began to notice that the asthma endured while the anxiety about being in the car had not. So I began to presume that driving was exposing me to the fumes of the other road users, either sitting in traffic or driving on busy British motorways... You're basically driving through all the fumes left in the road by those ahead of you!

But then I noticed yet another thing. The roads didn't have to be busy & if we travelled easily, for example over certain holidays or in the evening or at night, I still had the same problem. Twenty minutes in the car & I'd need my inhaler!

So I began to wonder if perhaps the push for greener exhaust meant that less of it was being expelled by the exhaust system, so as to dodge emissions targets, & instead was leaking into the vehicle. In the UK it's almost always cool, if not cold, so we almost always had aircon warming the car. And of course, cooling it on those rare summer days. I surmised that a percentage of the exhaust was getting into the aircon system, sitting literally right behind the engine, instead of being expelled from the rear of the car, where it is registered in testing.

So it's not just airplanes. It's cars too! My missus had a Toyota Aygo.

I should mention that one time, probably over Xmas with my missus extended family, I mentioned that I was thinking wearing a cycling mask in the car because of concerns about pollutants & I was roundly laughed out of the room.

Of course, they all ignored us & took the vaccines.

The rates of sickness is going to depend on aircraft to aircraft engineering vulnerabilities and servicing as mentioned. To tell how vulnerable the average passenger is, you would need to compare commercial aviation health disability rates of airline workers from country to country.

Great essay is chock full of important info. The air cabin thing brings to mind the times when I got a whiff of fuel exhaust when flying for eork. Glad I be retired and rarely travel by plane.

About the removal of root canal teeth and implants, are we just supposed to be toothless?

Yes important question. Gammal says that acrylic bridges work well and cause few problems. Zirconia ceramic implants are promising and I'm investigating them. Titanium causes lots of problems.
