Toxicity
Toxicity is the degree to which a substance can damage an organism.[1] It is the subject-matter of toxicology.
A central idea in toxicology is that almost everything is toxic when taken to excess. Effects are dose-dependent: even water can lead to 'water intoxication' when taken in too much. For even a very toxic substance such as elapid snake venom there is a dose below which there is no toxic effect.
Toxicity is species-specific.[2] A dose which is toxic to one animal may not be toxic to another.
