The ability of a chemical to cause harm to an organism with only one exposure.

Explanation:
Acute toxicity is about harm from a single exposure. When a chemical can cause adverse effects after only one encounter, that immediate or short-term harm is described as acute toxicity. This contrasts with chronic toxicity, which results from long-term or repeated exposure; repeated-dose toxicity examines effects from multiple exposures over time; and delayed toxicity refers to harmful effects that appear after a delay following exposure, not necessarily right away. So a one-off exposure causing harm fits the idea of acute toxicity.
