Which component is included in the environmental health risk assessment alongside hazard identification, exposure assessment, and dose-response?

• A. Hazard identification
• B. Risk management
• C. Risk characterization
• D. Public education campaigns

Answer: (C)

In environmental health risk assessment, the four key steps are hazard identification, exposure assessment, dose–response assessment, and risk characterization. The question asks which component completes this set alongside the first three, and the answer is risk characterization. This step pulls together what hazards are present, how people are exposed, and how different doses relate to adverse effects to estimate the overall risk to health. It also conveys the amount of uncertainty and variability in the estimate, giving a concise picture of how serious the risk is and how confident we are in that assessment.

Risk management and public education campaigns are important activities related to communicating and addressing risk, but they occur after the risk assessment step and are not part of the formal risk assessment process itself.
