Acute toxicity refers to toxicity from

• A. A single exposure to a pesticide
• B. Repeated exposures to a pesticide
• C. Exposure over years
• D. Exposure through ingestion only

Answer: (A)

Acute toxicity means the adverse health effects that show up soon after exposure to a pesticide, typically from a single exposure or a brief exposure event. The emphasis is on the quick onset of symptoms, rather than the amount of time over which exposure occurs. Repeated exposures over time can lead to chronic or subchronic toxicity, which develops from longer-term accumulation. Long-term exposure over years falls into the chronic category, not acute. The route of exposure (ingestion, inhalation, or skin contact) isn’t what defines acute toxicity; it’s the short time frame of the effects. So a single exposure is the best descriptor of acute toxicity.
