Prussian Blue is not just an innocent Dye
Yes, it is. I know that you're not a chemist and I'm not either, but this is what the chemists say. Simply having an element that's dangerous on its own in a chemical compound does not necessarily make the compound dangerous, which is why when you sprinkle some salt on your soup, the soup doesn't explode and you're not overcome by toxic gas. In fact, if you don't get enough salt in your diet, you will die. It's a good thing that when sodium is combined with chlorine, the result does not behave like sodium and chlorine.
Just reading some other things and noticed that - "The August 1965 autopsies and NS coronor's report determined that all four had died by drowning at the bottom of the 27-foot shaft, and suggested that it was carbon monoxide poisoning (from fumes emenating from the gasoline-powered pump that was running at the surface and, being heavier than air, filled the pit) which caused Robert Restall, his son Bobbie, Karl Graeser, and Cyril Hiltz each to lose consciousness and fall off the ladder and into the bottom of the watery shaft."
Carbon monoxide and hydrogen sulfide kill via a similar mechanism, by bonding to the iron in your blood and preventing oxygen from doing the same. Do they leave the same evidence in the body though? I don't know and I don't feel like running this one down. I wonder if poisoning via one can be confused with the other. Probably not, but it's something that's never occurred to me before.
The preferred method is to chelate heavy metals with massive doses of vit C . I personally know, since I have beem poisoned by both Arsenic and cyanide due to carelessness in assaying - no excuse, just familiarity. I am not dead just smell that way,I need to fix the hot water heater in the shower.
Incidentaly As is a poor choice for protecting something, You can generally make off with a treasure before any acute symtoms appear.
You should have been dead ten times over, half a century ago. I no longer trust your preventatives, Joe. I'm now convinced that you're not actually able to die, so your solutions to preventing death are probably invalid.
The Canadian Government (without an autopsy) then changed it to "Hydrogen Sulfide" with the explanation that apples had fallen into the hole.
That's a rather odd qualifier. Apples are not required. A wet hole in the ground is sufficient on its own.
Robert Restall would have been very aware of the rotten egg smell associated with this poison, but it was never reported.
Skip back a page or two. When the levels are high enough, you'll only catch a whiff...maybe not even that.
No, the rapid rate of death for all four in my opinion could only have been contributed to...Hydrogen Cyanide...
Define rapid. This stuff is deadly, but it works over minutes, not seconds. Believe it or not, I had training on how to deal with this a decade or two ago, in another life. The main takeaway from that was that if you smell bitter almonds, it's time to go. What I'm taking away from Wikipedia is that this is basically correct, but one or two of the guys with you may not smell it, as it's a genetic thing. Fortunately I never had to find out whether or not I could smell it. It would have only been an issue if things had gone terribly wrong, which they never have.
Before anyone asks, some torpedoes run on a fuel that produces hydrogen cyanide when it ignites. A fuel fire would produce this. The focus was on putting the damned fire out. Best defense is a good offense and all of that. I'm just remembering the highlights.
from the Pure Prussian
Blue the Freemasons had placed in this tunnel.
As a reminder, if they placed "Pure Prussian Blue" in there, it's non-toxic. If they placed hydrogen cyanide in there, it's not blue. In either case, it may not fit with your timeline. There are dates associated with both substances.
Fish kills are another subject entirely, and a very interesting one. We've had a few over the years out here, including an ongoing "fish massacre" in the Hood Canal. There are a couple of workable theories that can explain this. I'm fairly confident in one of them. It doesn't involve hydrogen cyanide. None of the others do either. Things may be different in your neck of the woods, but I'd look at the existing theories before advancing one like this. We don't know everything about anything, but we usually know something about that thing.
Just my opinion. Take it for what it's worth.
