Exposure Assessment is defined as...

• A. Process of estimating or calculating potential exposure of a health threat for an individual or population.
• B. Process of identifying hazards
• C. Health Risk Estimate
• D. Mission Statement

Answer: (A)

Exposure assessment is the process of estimating how much contact people have with a health hazard, considering who is exposed, what they are exposed to, and the magnitude, duration, and route of that exposure. It involves measuring or modeling contaminant levels in air, water, soil, or food and combining that with information about people’s activities and physiology to estimate actual or potential doses. This step provides the exposure magnitude and patterns that feed into risk calculations. It’s separate from identifying hazards (which asks what could cause harm) and from producing a health risk estimate (which combines exposure with dose–response to quantify risk). A mission statement is unrelated to assessing exposure.
