Key feature of ES-Modifier (Complicated) exposure assessment models assessible to DU –Establish the common boundaries that DUs can move within – preferably on an EU-association level –Flexible modification of use scenario from one set of OCs to another –Standard reference for DUs potential later implementation in own IT-systems Translates expert language into an interphase understandable by DU-formulator.

Conclusion Important to have an ES-modifier tool for DU- formulator Requirement: –Agreement on models across M/Is and DUs. Models should be flexible and not overly conservative. –Formalised structured parameters required to be given by supplier in ES: DNEL/PNEC; PEC regional ; Phys.-Chem. Data. –Active role by DU-branch associations on a European scale – preferably across several industry sectors. –As broad as possible to pay the cost of the validation needed between the stakeholders
