List of Poisons

Relative Toxicity of Chemicals


Poison Symbol

Any chemical becomes poison if you are exposed to enough of it and in the wrong way.

This is a list or table of chemicals that can kill you. Some of these poisons are common and some are rare. Some you need in order to live, while others you should avoid at all costs. Note that the values are median lethal values for an average human. Real-life toxicity depends on your size, age, gender, weight, route of exposure and many other factors. This list just offers a glimpse at a range of chemicals and their relative toxicity. Basically, all chemicals are poisonous. It just depends on the amount!
