The very first step in the risk assessment is problem formulation which defines the problem. This process explicitly identifies the components and sets the stage for the Risk Assessment (Environment Canada 2003, Health Canada 2004). All three components are essential in order for a contaminant-based health risk to exist. Absence of any one will remove the possibility of an unacceptable health risk.
