Which component integrates hazard identification, exposure assessment, and dose-response to estimate risk and its significance?

• A. Integrates hazard identification, exposure assessment, and dose-response to estimate risk and its significance
• B. Only catalogs hazards
• C. Only measures exposure
• D. Only determines cheap alternatives

Answer: (A)

Risk assessment combines hazard identification, exposure assessment, and dose–response to estimate risk and its significance. Hazard identification asks what adverse effects a substance can cause. Dose–response describes how the likelihood or severity of those effects changes with dose. Exposure assessment estimates how much of the substance people are exposed to, including route, duration, and frequency. By integrating these components, you arrive at a risk characterization that quantifies both the magnitude of risk and its significance for a given population or scenario. The described option matches this integrated approach to estimate risk and its significance. The other choices are incomplete: cataloging hazards alone ignores exposure and dose–response; measuring exposure alone misses hazard and dose–response; looking for cheap alternatives does not address toxicity or risk assessment.
