Acute toxicity describes the bad effects of a substance that come either from a single exposure or from many exposures in a short amount of time (usually less than 24 hours). To be known as acute toxicity, the bad effects should happen within 14 days of the substance thouching something.
Acute toxicity is different from chronic toxicity. Chronic toxicity talks about the bad health effects from many exposures, often at lower levels, to a substance over a longer amount of time (months or years).
It is widely thought to be wrong to use humans as tests for acute (or chronic) toxicity research. However, some information can be picked up from investigating cases when humans accidentally make contact with the substance (e.g., factory accidents). Otherwise, most acute toxicity data comes from animal testing or, more recently, in vitro testing methods and inference from data on similar substances.
