Dans la caractérisation du risque, il faut tout d'abord déterminer la concentration à laquelle la substance n'aurait probablement pas d'effets sur les points finaux d'évaluation. Il s'agit de la valeur estimée sans effet observé (VESEO), qui est ordinairement calculée en divisant la VCT [valeur critique de la toxicité] par un facteur d'application.
