Abstract
The Benchmark-Dose (BMD) approach aims at determining an exposure level/dose corresponding to a predefined change in response, the Benchmark Response (BMR), usually defined over background using all available dose–response (DR) information by fitting mathematical models to the dose–response data. The statistical confidence interval of the BMD (BMD-CI) accounts for the statistical uncertainty and the lower (one-sided) confidence limit, denoted BMDL, is used as reference point (RP) or point-of-departure (PoD) for the characterization of the risk of hazardous compounds replacing the no-observed-adverse-effect level (NOAEL) when sufficient DR data are available. Concept, scope of application, prerequisites for conduct, and key check points of the application of the BMD approach are presented and guidance is given for regulatory practice. The use of the BMD-CI for establishing a Health Based Guidance Value (HBGV) or a Margin of Exposure (MoE) is outlined.
