What is the most poisonous man made chemical?

Answer 1

The most poisonous man made chemical is called dioxin...-Dak
I'm not sure there is agreement that dioxins are the most toxic (dioxins are actually a class of molecules in fact, the most toxic of which is call TCDD), but they are certainly high on the list. I found this at ens-newswire.com (see link on the left): "STOCKHOLM, Sweden, May 17, 2004 (ENS) - An international treaty banning 12 of the world's most deadly chemicals enters into force today - the 2001 Stockholm Convention on Persistent Organic Pollutants (POPs). Under the agreement, more chemicals can be added to the prohibited list but for now the 12 initial POPs are - aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex, toxaphene, polychlorinated biphenols (PCBs), hexachlorobenzene, dioxins and furans." See the Related Links to the left for the answer.

Answer 2

One of the most poisonous man-made chemicals is VX nerve agent, which is a potent neurotoxin that disrupts the nervous system and can be fatal even in very small doses. VX is classified as a chemical weapon and is banned under international law.
