Acute toxicity timeframe question: Acute toxicity is typically within what time frame?

Acute toxicity means harmful effects that appear soon after exposure, typically within a short window. In pesticide toxicology, symptoms from an acute exposure are usually evident within 24 to 96 hours. The other timeframes describe effects that develop over days to weeks or longer with repeated exposure, which are not considered acute. So the 24-96 hour period best represents acute toxicity.
