The Information-Gathering Process

Risk assessors should integrate information about:

• The stressors.
• The characteristics of the ecosystems potentially at risk.
• How those ecosystems might be exposed to those stressors.
• What effects might result from that exposure.

This information provides the foundation for the remaining three steps in problem formulation.
