Acute toxicity refers to the immediate effects after a single exposure, or within how many hours?

Explanation:
Acute toxicity deals with short-term effects that appear soon after a single exposure. The standard window used to capture these immediate responses is within 24 hours. That means if symptoms show up within a day of exposure, it’s considered acute; if effects occur after that period, they’re typically viewed as subacute or chronic depending on the duration and dosing. So 24 hours is the best fit for defining acute toxicity.
