Prussion-blue
I was thinking about Prussian-blue, the color in which fumigation chambers at Auschwitz had become from delousing with Zyklon gas. And the fact that some researchers could find ample traces of cyanide and Prussian-blue in the fumigation chambers and not in the gas chambers.
The fumigation chambers were meant to kill lice, very small bugs. These chambers possibly turned blue from over saturation from fumigation because of the size of the inhabitants and the very lack of their absorption rate. Those inhabitants took in far less gas than those whom were being exterminated in the gas chambers. Humans are able to take in much more of the gas, and their bodies are far better at absorbing the gas than that of a louse.
So, I'm thinking that the reason that the samples taken from both chambers revel different amounts of cyanide, being a heck of a lot to none at all are a result of the size of the occupancy and the differences in how they absorb. It takes much longer to kill lice than humans. So, in that regard, the testing of the color and the lack of cyanide to the scrapings from the areas in which were tested could have had the result they had due to my recent ideas regarding the situational differences between both chambers and the usage of them.
That said, the thought might make one leap from denial to acceptation. I don't know yet. Still researching. Still thinking...
