Injury produced from a single toxic exposure is called _____ toxicity.

Explanation:
Acute toxicity is the injury that results from a single, short-term exposure to a toxin. When harm happens after one dose or brief contact, it’s classified as acute. Chronic toxicity, by contrast, comes from repeated or long-term exposure and accumulates over time. LD50 isn’t a type of toxicity; it’s a statistical measure of potency—the dose that would kill 50% of a test population—used to compare how toxic a substance is. Lethal describes death-causing potential, not the exposure pattern itself. So the correct concept for a injury from a single exposure is acute toxicity.
