  7. ES-Modifier Prototype 1/2 GENERIC USE SCENARIO: • Application of paints; adhesives; sealants and cleaning agents on surfaces • Professional/Consumer • In-door/Out-door • Manual or Spray application • +++ other OC’s

  8. ES-Modifier Prototype 2/2 Human exposure assessment • Inhalation: Stoffenmanager (other choices possible) • (Dermal inhalation) Environmental exposure assessment: EUSES • Water • Water, STP • Soil (Excel version, RIVM/Radboud University)

  17. Input parameters: Conc: 25% Professional In-door Spray with aerosols Room size < 100m3 Large surfaces No ventillation + Half mask OUTPUT Exposure: Human/Env. Exposure/DNEL; PNEC +/- RMM

  18. 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.

  19. EUSES – calculation of PEC Lifecycle step Emission fractions MC: Main category Emission days UC: Use Category A/B tables Fraction of main source IC: Industry Category STP + Annual Production Concentration PEClocal = PEC + PECregional

EUSES – calculation of PEC Lifecycle step Emission fractions MC: Main category Emission days UC: Use Category A/B tables Product type Fraction of main source IC: Industry Category +extra User segment STP + Product technology Annual Production Sales outlet Concentration PEClocal = PEC + PECregional Can be ”overwritten” by ”expert DU” Default values DU-input

  22. Use: Brush application Adhesives assortment – real data Stoffenmanager Stoffenmanager > Ecetoc X=Y Where: In-door How: Manual Area: Medium Room: < 100 m3 # of operations: 1 Stoffenmanager < Ecetoc Vapour pressure Concentration Ventillation/LEV: No Duration: 8hrs Ecetoc class: 1 (Roller/Brush)

  23. Use: Spray application Adhesives assortment – real data Stoffenmanager Stoffenmanager > Ecetoc X=Y Where: In-door How: Spray w. aerosols Area: Large Room: < 100 m3 # of operations > 1 Stoffenmanager < Ecetoc Vapour pressure Concentration Ventillation/LEV: No Duration: 8hrs Ecetoc class: 2 (Spray)

  24. 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
