Hazard characterisations

Hazard characterisations are benchmark doses for active substances and for the chosen effect at the chosen target level (external or internal) of the hazard assessment. Hazard characterisations are based on points of departure, such as BMDs from dose-response models or externally specified points of departure (MDSs, NOAELs or LOAELs). The computation may involve inter-species conversion, intra-species factors and the use of kinetic models or absorption factors to convert external doses to internal doses. An extra option provides the possibility to use an additional assessment factor. This factor may be used to bypass inter- and intra species conversion, or may be used as an additional assessment factor to account for extrapolation for sources where appropriate data or information is scarce or missing.
