5.3.3.11 Good Exposure Assessment Practice
Several studies are dedicated to the performance of a decent Exposure Assessment
such as the
Good Exposure Assessment practice
(e.g., Hawkins et al.
1992
;US
Environmental Protection Agency
1992
;WHO
2005
). Like most Risk Assessment
elements, good Exposure Assessment practice underwent an evolution from the late
Table 5.2
Ten steps involved in good Exposure Assessment practice (partly based on ECETOC
2001
)
Steps involved
Persons involved
1
Draw-up of a project plan, including a
description of the following 9 steps
Project manager, primarily; secondary
regulator
2
Determination of the purpose of the
Exposure Assessment
Project team
3
Organisation of personnel, funds and (when
appropriate) facilities
Project manager
4
Identification of the stakeholders
Project team
5
Identification of political boundary
conditions
Project manager and decision-maker
6
Selection of risk tools, including:
•
special attention to the balance between
calculations and measurements (in body
fluids and tissues);
•
a choice for deterministic or probabilistic
Risk Assessment;
•
information about the most important
input parameters (including a
sensitivity/uncertainty analysis)

information about the (validation) status
of models, protocols, equations, lists,
graphs, etc.;
•
the procedures for the determination of
input parameters (including expert
judgement processes)
