This transfer model can be used to estimate the concentration of dioxins in egg yolk fat and body fat of the laying hen based on oral exposure to feed contaminated with dioxins and dioxin-like PCBs using contamination levels of individual congeners. For estimations based on total TEQ levels only, the user is referred to the transfer model dioxins (total TEQ) laying hen". General information on how to use the transfer models on this website can be found under “How to use”. The specific manual for the dioxins (congener-specific) – laying hen can be found here. Detailed information about the model can be found in the model documentation as well as in the literature described below. A log with the changes made after the release of version 1.0 of the model can be found here.
