When a person has been exposed to an acutely toxic dose of a substance, they can be treated in a number of ways in order to minimize the harmful effects. The severity of the response is related to the severity of the toxic response exhibited. These treatment methods include (but are not limited to):

It is widely considered unethical to use humans as test subjects for acute (or chronic) toxicity research. However, some information can be gained from investigating accidental human exposures (e.g., factory accidents). Otherwise, most acute toxicity data comes from

The most referenced value in the chemical industry is the median lethal dose, or LD50. This is the concentration of substance which resulted in the death of 50% of test subjects (typically mice or rats) in the laboratory.

Limits for short-term exposure, such as STELs or CVs, are defined only if there is a particular acute toxicity associated with a substance. These limits are set by the
