This transfer model can be used to estimate the concentration of several non-dioxin-like polychlorinated biphenyls (ndl-PCBs) in egg yolk fat and body fat of the laying hen based on oral exposure to feed contaminated with ndl-PCBs using contamination levels of individual congeners. General information on how to use the transfer models on this website can be found under “How to use”. The specific manual for the ndl-PCBs (congener-specific) – laying hen can be found here
