poisonousness

Capacity to kill

Poisonousness is the quality of being poisonous—capable of causing harm, illness, or death through chemical action.

The word applies literally to substances and organisms: the poisonousness of certain mushrooms, the poisonousness of snake venom.

It extends to anything toxic or corrupting: the poisonousness of their rhetoric.
