What is the most toxic chemical known to man?

Answer 1

I believe that the substance known as botulinum is one of, if not the deadliest toxin known. Wiki has its own page describing this toxin.

Yes, the deadliest substance known to man is botulinum toxin produced by a bacteria. It has an LD50 of .05 microgram/Kg which means for a 70 kilogram man would only need to ingest only .0035 mg to have a fifty percent shot at death.

Answer 2

There are lots of criteria for determining what "most deadly" mean, as mortality speed, chance of recovery, lethal substance amount, how quickly it spreads, etc. are all considerations. Some of the most lethal substances I've heard of would be VX nerve agent and phosgene gas, although there are many other lethal chemicals out there.

Answer 3

Researchers at the U.S. Department of Energy's Ames Laboratory made a gem of a discovery while tinkering with an unlikely material -- it's the second-hardest bulk substance after diamond.

By introducing a small amount of silicon into an alloy of aluminum, magnesium and boron, they created a material slightly harder than cubic boron-nitride, the material now ranked second. But the Ames researchers hope that experiments with other additives will make it even harder.

Cyanide is a very dangerous chemical. This chemical prevents oxygenation of the body from blood, killing the body. In short, blood carries oxygen, cyanide prevents blood from carrying it, and no oxygen=dead.
