Examines the underlying structure and philosophy of the
Estimation and Assessment of Substance Exposure (EASE) model
version 2.0, developed by the UK Health and Safety Executive (HSE).
EASE is a knowledge-based modal used by regulators for assessing
new and existing substances. Aimed to provide a critical assessment
of the utility of its performance to date. Information was
documented by gathering surviving evidence and interviewing
personnel involved in its creation and development. Twenty seven
stakeholders participated in structured interviews on issues such
as the limitations of the model, suggestions for improvement and
accuracy and precision. They were also asked to comment on what
outputs they would like to obtain from an ideal model. Outlines
recommendations for the structure of a revised exposure
model.
