acute toxicity (Acute toxicity describes the adverse effects of a substance that result either from a single exposure[1] or from multiple exposures in a short space of time (usually less than 24 hours).[2] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance.[2] Acute toxicity is distinguished from chronic toxicity, which describes the adverse health effects from repeated exposures, often at lower levels, to a substance over a longer time period (months or years).
