Do you know what is toxic ??

Do you know toxic is very dangerous to our body??

Toxicity is the degree to which a substance is able to
damage an exposed organism.
Toxicity can refer to the
effect on a whole organism, such as an animal, bacterium,
or plant, as well as the effect on a substructure of the organism, such as a cell (Cytotoxicity) or an organ (organotoxicity), such as the liver (hepatotoxicity).
By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large.

A central concept of toxicology is that effects are dose-dependent; even water can lead to water intoxication when taken in large enough doses, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect.
