It isn’t a forum for ‘denial’ of anything. It’s a forum for genuine discussion of history. That’s why people have become frustrated with you, as you clearly are here with some other agenda.

I would ask what he thinks he will achieve by being here then? His low expectation of us means he is already predisposed to disagree and disregard what we say. He has an agenda and has no real desire to change his position that Herr Hitler and his band of merry men deaded 6m jews who didn't exist in gas chambers that cannot be shown.
Of the four million jews under German control, six million died and five million survived!

I am still waiting for any kind of argument resembler something slightly plausible to explain the chemical traces of cyanide in LK2.

How is he still not getting it? This would be alarming if it weren't so hilarious.

The highest trace that Markiewicz found was 640 µg/kg which equates to 0.64 ppm.

This is 1,000 times lower that what is found in an apple

This has all been explained to you before, see below. Cyanide as a chemical being found in nature in such ridiculously tiny quantities is not only meaningless, but it is laughable that you think this microscopic trace amounts lingered around in the unbound state for 80 years as proof of the holocaust, when we know that cyanide is completely unstable in this state.

Lol, LK1 is the supposed gas chamber. LK2 is the supposed undressing room.

You keep posting this in every topic, so you must think it's a pretty strong argument, but you've apparently missed that it's already been answered numerous times. Let me dumb it down for you.

Markiewicz et al 1994's highest cyanide reading from Crema II LK1 is 0.64 mg/kg. That is, just 0.000064% of the sample was measured to be cyanide. This is an incredibly small proportion, a number which would be considered below the margin of error in nearly all human pursuits.

Taking it as true, there is no difficulty in explaining this finding. Cyanide exists in nature. It's in the ground, it's in plants, it's in car exhaust, and it's in the atmosphere as HCN. A finding of trace cyanide in any location could easily represent these ambient cyanides. HCN was also the standard disinfestation tool during the exact years that gas executions are alleged to have taken place here, so any finding of cyanide could be the result of disinfestation.

As you yourself argued in a previous post, cyanide readings can be explained away as being the result of "contamination from weathering, renovation, or debris" or by merely being "adjacent" to somewhere gas was used. See this post: https://www.codohforum.com/viewtopic.php?p=12835#p12835.

You will now want to argue something about control samples, but it's already well-established that non-homicidal locations also had cyanide readings in the same range. These include living barracks, a washroom, an undressing room, and a farmhouse. See this thread: https://codohforum.com/viewtopic.php?t=463

Wow! CJ couldn’t even understand the simple question from Keen, let alone answer it. :?

CJ, focus now, he asked you to explain exactly what you think he is actually D E N Y I N G.

Do you understand?

I didn't say that it can be explained away. It wouldn't come close. And the controls showed zero cyanide. This is where it's very clear and simple to me that there was cyanide usage in that room if it was still detectable decades after.

Contamination can occur if samples are mishandled or exposed to modern cyanide sources in a lab. However, forensic studies of these sites often use strict chain-of-custody and cross-check samples from control locations to minimize this risk.

Studies (including by forensic experts like Jan Markiewicz in the 1990s) found trace cyanide residues in former homicidal gas chambers, with much higher levels in delousing chambers.

The distribution pattern of residues — concentrated on walls exposed to Zyklon B gas — matches historical use, not random contamination.

Well, that's rude and most definitely a projection.

The fact that apple seeds have more cyanide per gram than the highest residues found in gas chamber walls does not diminish the significance of the gas chamber findings.

The gas chamber cyanide residues reflect a different kind of chemical process — cyanide bound or trapped in building materials after exposure to hydrogen cyanide gas, not free cyanide or concentrated cyanogenic compounds. In apple seeds, cyanide is present as cyanogenic glycosides, which are organic compounds that release cyanide only upon digestion or crushing.

The very low ppm range (sub-1 ppm) in walls is consistent with decades of environmental degradation, weathering, and the chemical nature of cyanide binding in bricks/mortar.

The comparison highlights that cyanide presence in walls at sub-ppm levels is plausible and consistent with chemical expectations.

It demonstrates that absence of very high cyanide concentrations in gas chambers is not surprising or suspicious, given:
Short exposure times to Zyklon B gas.
Environmental weathering for decades.
Differences in chemical binding and physical context.

Analytical methods used (like Markiewicz’s microdiffusion/colorimetric test) detect cyanide reliably at levels much lower than 0.64 ppm—sometimes down to single µg/kg (ppb) levels.

Background samples taken from nearby, unrelated buildings at Auschwitz consistently showed no detectable cyanide. So the local geological environment and construction materials do not naturally contain cyanide at this level.

If 0.64 ppm were just background noise, you'd expect similar levels across all sampled buildings, but that is not the case. Cyanide residues are found only in specific rooms historically documented as gas chambers or delousing chambers.

Adjacent rooms, unrelated buildings, and control sites show no or negligible cyanide. This non-random spatial distribution makes contamination or background origin extremely unlikely.

Forensic protocols include chain-of-custody for samples, use of blanks and controls, and analysis by multiple independent labs. Consistency of results across labs and over repeated tests argues against lab contamination.

In addition to that, cyanide residues are just one part of a larger forensic and historical puzzle.

When you insult me and speak to me like that, it strongly suggests that you don't know what you are actually talking about and just repeating what you read from Rudolf et al.

My contention was that cyanide traces in the control samples were roughly equal to those in the supposed gas chambers. You offered "contamination from weathering, renovation, or debris" and adjacency as explanations for that. If you find these to be sufficient explanations for trace cyanides in the control samples, then surely they are also sufficient explanations for trace cyanides in the supposed gas chambers.

To the contrary, Leuchter, Rudolf, and Mattogno all took control samples that came back positive for trace cyanides. In all three cases their total cyanide content was actually higher than what Markiewicz measured by his method in any of his samples.

You know nothing about the chain of custody in any of these investigations, but chain of custody is not even in dispute here so it's totally irrelevant.

You can keep asking your AI to say this as many times as you like, but nearby buildings have in fact been found to have cyanide readings of 1.2, 1.3, and 9.6 mg/kg.

Instead of trying to understand why we don't believe in the Holocaust, it would be better for you to explain what convinces you to believe it happened and prove by A + B that the evidence you find essential actually corresponds to the proposed narrative.

That has been done, multiple times, by the historians who have researched A-B. This is a list of links to primary evidence, documents, witnesses, forensics and circumstantial evidence, that corroborates and converges to prove mass gassings and cremations;

https://holocaustcontroversies.blogspot ... ce-on.html

"Transfer inventory of 24 June 1943 on “14 showers” and “1 gas tight door” in crematorium 3 [Pressac, Technique , p. 430]"

That document corroborates witness descriptions of gas chambers made to look like showers.

"The showers were fitted to small blocks of wood sealed into the concrete roof of the gas chamber. There were no pipes connected to these showers, from which no water ever flowed."
