Key feature of ES-Modifier
• (Complicated) exposure assessment models assessible to DU – Establish the common boundaries that DU’s can
move within – preferably on an EU-association level– Flexible modification of use scenario from one set of
OC’s to another– Standard reference for DU’s 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/I’s and DU’s. Models
should be flexible and not overly conservative.– Formalised structured parameters required to be given by
supplier in ES: • DNEL/PNEC; PECregional; 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
