Predicted no

The Predicted No Effect Concentration (PNEC) is the concentration of a chemical which marks the limit at which below no adverse effects of exposure in an ecosystem are measured PNEC values are intended to be conservative and predict the concentration at which a chemical will likely have no toxic effect They are not intended to predict the upper limit of concentration of a chemical that has a

Addendum

However the guidance for PNEC derivation given in the TGD refers to an exposure situation which is completely different from the exposure situation for rodenticides Also in the ESD PT14 it is questioned "if the PNECoral calculated according to the TGD is really very suitable for rodenticides" One issue not yet discussed at TM regarding PNECoral derivation for the primary and
