A conceptual site exposure model should be created to illustrate and explain how the contaminant sources, exposure pathways and receptors are linked together to form the potential for health risk. This step should involve a simple diagram and short description of these interrelationships. The conceputal exposure model provides the basis for developing the mathematical exposure model and estimation of health risks.
Example 1: schematic picture of conceptual exposure model.
Example 2: schematic flow diagram of conceptual exposure model.
