What is a receptor pool, and how does it relate to dispersion modeling?

• A. A pool of water receptors in sampling.
• B. A set of receptors used to assess potential exposure across a site.
• C. A term for the set of meteorological inputs.
• D. A group of sensors used to measure emissions.

Answer: (B)

In dispersion modeling, a receptor pool is the set of receptor locations you use to estimate potential exposure across a site. Think of it as the grid or network of points where the model reports concentrations or doses so you can see how impacts vary spatially and determine who might be exposed and to what extent. This collection helps you map exposure across neighborhoods, workers, or sensitive areas and to compare results against health-based benchmarks. It’s not about water sampling, meteorological inputs, or sensors measuring emissions. Those elements provide data that feed the model (weather conditions, emission rates), but the receptor pool is specifically the chosen locations where the model outputs—the estimated impacts—are evaluated. For example, you might place receptors at multiple locations around a facility to capture potential exposure across the surrounding area, then use those results to assess risk or compliance.
