Validation of the aggregated model and comparison with USA software

Summary
The modelling approach for aggregate exposure implemented in WP 6 will be validated by ANSES and DLO-B. Validation of the software for aggregate exposure assessment is important. The new model for aggregate exposure assessment will be validated in two different ways. First, unit tests will be written to assure the proper working of the code at a low level. These unit tests will simulate data with known outcomes, and check that the software performs adequately. DLO-B will set up simulation studies and will compare model outcomes with the true values behind the simulated data. Secondly, the new software is compared to the standard program for the exposure assessment of pesticides in the US by the EPA, which is DEEM-SHEDS. For the aggregated models ANSES, with the help of DLO-B, will compare the EuroMix model with the model used in the EPA (e.g. SHEDS-Multimedia). ANSES and DLO-B will write a validation report (D7.1, M36)
