What Is the Most Poisonous Chemical Compound?

Answer 1

Most Poisonous Chemical

Answer 2

When you get right down to it, everything is poisonous. Water will kill you if you drink too much of it. Oxygen is a deadly poison, yet we need it to live. However, there are some chemicals that we are better off not encountering. Here's a list of the most poisonous chemicals known. Keep in mind, toxicity varies from one species to another (i.e., what may be poisonous for a mouse may be more/less poisonous to a human) and within a species (i.e., age, sex, genetics all affect susceptibility to a toxin). I've listed the name of the toxin, its source, approximate average lethal dose per kilogram of body weight (LD50), and the species.

1. tetanus
1 nanogram/kg
mouse, human

2. botulinal neurotoxin (bacteria)
1 nanogram/kg
mouse, human

3. shigella (bacteria)
1 nanogram/kg
monkey, human

4. palytoxin (coral)
60 nanogram/kg
dog (iv)

5. diphtheria (bacteria)
100 nanogram/kg
human

6. ricin (from castor beans)
1 microgram/kg
human

7. aflatoxins (mold which grows on nuts, legumes, seeds)
1-784 micrograms, depending on type of aflatoxin
duckling (oral)

8. shigella (bacteria)
1 microgram/kg
mouse

9. saxitoxin (shellfish)
3-5 micrograms
mouse (iv), about 50x higher dose orally

10. tetrodotoxin (fugu pufferfish)
10 micrograms
mouse (ip)

11. diphtheria (bacteria)
1.6 milligram/kg
mouse

Answer 3

how do you mean most poisonous? faster to kill or does most damage to the body.

Cyanide is used in the gas chamber, works in less than a minute because you breath it, an injection would be just as fast or faster.

the are to many chemicals that can kill you though

hydorflouric acid will eat you away and poison and kill you if you even get a small slash on you...

there is no "most" or "deadliest" really
