FI: ennustettu pitoisuus ympäristössä (PEC) [T50879]
DE: PEC, predicted environmental concentration [T50879]; vorhergesagte Konzentration in der Umwelt [ENV]
FR: concentration prédite dans l'environnement (PEC) [T50879]
The objective of the exposure assessment shall be to predict the concentration of the substance which will eventually be found in the environment. That concentration is known as the predicted environmental concentration (PEC). However, in some cases, it may not be possible to establish a PEC and a qualitative estimation of exposure would have to be made.
