Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The method described for estimating the distribution is well accepted scientifically. The fugacity model level III used for estimating the distribution is based on the EPIWin (Estimation Program Interface) Suite, Suite of environmental predictive models developed by the U.S. EPA and Syracuse Research Corporation.

Results and discussion
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
