 A
conceptual model is a visual representation (a map, flow chart,
or schematic) of hypothesized relationships between ecological
entities and the stressors to which they may be exposed, accompanied
by a written description of this process and of the risk questions.
|
Conceptual models for ecological risk assessments are developed
from information about:
- Source.
- Stressors.
- Receptors.
- Potential exposure.
- Predicted effects on an ecological entity (the assessment endpoint).
Depending on why a risk assessment is initiated, one or more of
these categories of information are known at the outset. Creating
conceptual models helps identify the unknown elements.
