Risk Assessment of PECsoil in the Evaluation Procedure in Europe

Learning Outcomes:

• Learn how the PECsoil assessment in the EU is organised
• Learn how to perform PECsoil calculations at the initial tiers 1 and 2 using the analytical PERSAM model
• Learn how to use the results of PERSAM as input for higher tier calculations
• Learn how to perform higher tier calculations for PECsoil using the numerical models FOCUS PELMO and FOCUS PEARL
• Learn in how far groundwater simulations changed because of the new versions of FOCUS PELMO and FOCUS PEARL

This training is aiming to give you the basic knowledge on how to assess predicted environmental concentration of PPP and their active substances and metabolites in soil in the evaluation procedure in Europe. In a compact format of an intensive morning session, you will be familiarised with the philosophy of the PECsoil guidance documents of EFSA and the related software packages to perform individual PECsoil calculations. Compared to the traditional methodology the procedure for PECsoil includes scenarios for each of the three European zones. Furthermore, more processes are considered such as wash-off from crops and leaching to deeper soil layers. Finally, the PECsoil assessment is now embedded in a scheme of 4 different tiers including analytical and numerical models.

For a better visibility of the detailed calculations demonstrated during the training, we recommend to use a device with a large screen.
