For registration of agrochemicals in Europe, calculation of predicted environmental concentrations is mandatory. Input for the environmental fate models used for these calculations is frequently derived from terrestrial field dissipation studies. A new guidance for evaluating these studies is currently being developed by the European Food Safety Authority (EFSA). In this presentation, an overview of the procedure for deriving degradation rates as recommended in the existing material will be given, and the scientific background as well as implications on the study design will be discussed.
