Which term describes the result of an accidental or intentional single exposure to a toxicant?

• A. Chronic toxicity
• B. Acute toxicity
• C. Hypersensitivity
• D. Carcinogenicity

Answer: (B)

Acute toxicity describes the harmful effects that occur soon after a single exposure or short-term exposure to a toxicant. This captures the immediate response you’d expect from one-time contact, such as symptoms that appear quickly after ingestion, inhalation, or skin exposure. Chronic toxicity, on the other hand, results from repeated or prolonged exposure over time and may take longer to become evident. Hypersensitivity refers to an exaggerated immune reaction rather than the timing of exposure. Carcinogenicity deals with cancer-causing potential, typically studied over longer periods and not the immediate aftermath of a one-time dose. So, for a single exposure producing effects, acute toxicity is the best description.
