Acute exposure ties with which concept?

• A. Chronic toxicity
• B. Dermal irritation
• C. Acute toxicity
• D. Bioaccumulation

Answer: (C)

Acute exposure is about a brief, single, or short-term encounter with a chemical. The concept that best fits this situation is acute toxicity, which covers the immediate adverse health effects that can occur after such a short exposure. These effects typically show up quickly, within minutes to hours, and are often measured by acute toxicity metrics like LD50 or LC50. In contrast, chronic toxicity refers to effects from long-term or repeated exposure, such as cancers or organ damage that develop over time. Dermal irritation can happen from exposure, but it describes a specific skin reaction rather than the overarching idea of rapid toxic effects. Bioaccumulation describes buildup of a substance in an organism over time, linked to persistence and long-term exposure rather than the immediate response.
