1. Harmonisation (OC’s and RMM’s) of ES’s received from different suppliers.

2. Scale the ES according to specific needs (eg. customer request)

how to use es modifier
How to useES-modifier
  • Choose lifecycle stage (and user group)
  • Describe overall use according to DoU (Descriptors of Use)
  • Insert substance data (directly/plug-in)(Today ES-Modifier is substance based; future plans for preparations)
  • Choose models(Default models are Ecetoc TRA and EUSES)
  • Describe specific details of use
  • Make calculations and observe RCR results

Practical use of ’Descriptors of Use’

Evaluation of ES-Modifier by others

practical use of descriptors of use dou
Practical use of ’Descriptors of use’ (DoU)
  • DoU is the main tool recommended in guidance for
    • the identification of use
    • and the headline in the ES
  • DoU is input parameter to exposure models
    • PROC => Occupational exposure calculation
    • PC/AC => Consumer exposure calculations
    • LCS+SU/PC/PROC/AC => ERC=>environmental exposure calculations
  • Conclusion from case studies in RIP 3.2 and various workshops:
    • DoU is difficult to use/not reproducible
    • More help is needed to find your way around in DoU

2008

  • Improve tool on basis of feed-back
  • Workshop for stake-holders (November)
  • Discussion of responsibility with authorities
  • Validation of calculations – experts (and project team)
  • Validation of assumptions – experts

2009

  • Preparations (2009 action)
mixtures
Mixtures
  • Project on preparing a ”handy” guidance for preparing ES for mixtures
  • Paid by the Danish EPA
  • Project team:DI (project owner), DHI (hse consult)
  • Started spring 2008 - to be finished spring 2009
  • Two approaches being tested
    • DPD-method
    • RIP 3.5 guidance
  • Examples, examples, examples
