Where are poisons stored in the body?Storage and Binding
If the poison is not acute, then the poison must build up over time. Storage in adipose tissue (fat) will occur for those chemical compounds that are non-polar in nature. In some cases, especially those involving heavy metals, the poisons may be bound in the bones of the victim.
What is the most toxic poisoning?Botulinum toxin
Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
