here and here.
I'll be honest. There's too much information on Zyklon B for it to be easily condensed, and I hadn't the stomach to try and create a fiction piece. I wasn't there, and I've never really been able to wrap my mind around what it must have been like in the death chambers at Auschwitz.
Poisons A to Z: the Wrap-Up
Through time, many plants and animals evolved toxins - and methods of administration - either to protect themselves or to actively prey on others. At some point humans learned to use these poisons themselves, at first probably for hunting but as time went on, also to treat disease, kill unwanted vegetation and vermin, and...unwanted humans as well.

Mentions of deliberate poisonings date back to ancient Egypt, Greece and Rome. Poison was a very popular method of assassination. Mithridates VI was so afraid of being poisoned that he began to test substances on criminals, experimenting with various strengths and combinations as well as antidotes. He even administered small amounts of poison to himself in an attempt to gain immunity.
Agathodaimon, an ancient alchemist, makes mention of a“fiery poison”; when mixed with natron and dissolved into water, the water stayed clear, but when copper was dunked into it that water, it turned a deep green (which leads experts to believe that he was describing arsenic trioxide). Only fragments of his texts remain.
Persian physician and scholar Rhazes wrote Secret of Secrets, a book of chemical compounds, minerals and apparatus. His was the first mention of mercury compounds (such as mercury chloride) as medicine, particularly as a laxative and an ingredient in ointments for skin diseases like scabies (caused by mites, which the mercury killed) and weeping sores (such as those caused by syphilis).
A medieval poison ring was unearthed in Bulgaria in 2013. Murderous jewelry was thought of long before modern mystery writers came on the scene.
Poisons are still used today, both for good and for evil. People die daily, from accidental ingestion, environmental exposure, and by deliberate administration for purposes of murder (or 'sanctioned' execution).
The history of poison is intertwined with the history of mankind. I couldn't possibly cover all of them in the challenge. I've tried to use each post to highlight something unusual: a poison you might not have heard of, a more imaginative way to use it, a historical case which might be unfamiliar to you.
Other poisons/toxins/heavy metals which you may wish to research and include in your stories are listed below. (LInks are to my A to Z posts.) I have attempted to give each one a date or time frame, in case you are looking for a poison specific to a time period. The time is just a reference point; it doesn't mean that the poison was recognized as such. Many were first used as pigments, folk remedies, even hallucinogens. Some are also naturally occuring and have always been around, like mushrooms and castor beans. (I did not include all of the poisonous plants and venoms found in nature, as that would make the list far too long and unwieldy.)
