Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The level III fugacity modelling of EPIWEB v 4.1 was used on the structural analogue amides, C18(unsatd.), N,N-bis(hydroxyethyl), which is a direct adaption of the methodology of Mackay’s EQC model, which is a well established and validated distribution model.

Applicant's summary and conclusion
- Conclusions:
- The estimated percent distribution of amides, C18-unsatd., N,N-bis(hydroxyethyl) in air, water, soil and sediment, using Fugacity level III model (EPIWEB v 4.1) was 0.09, 23.78, 74.95 and 1.17 respectively. The estimated half life of the substance in air, water, soil and sediment, using Fugacity level III model (EPIWEB v 4.1) was 0.05, 15, 30 and 135 days respectively.
- Executive summary:
Distribution data in air, water, soil and sediment was estimated using Mackay level III fugacity modelling (EPIWEB v 4.1). This model is a direct adaption of the methodology of Mackay’s EQC model, and is a well established and validated distribution model.
The estimated percent distribution of amides, C18 -unsatd., N,N-bis(hydroxyethyl) in air, water, soil and sediment, using Fugacity level III model (EPIWEB v 4.1) was 0.09, 23.78, 74.95 and 1.17 respectively. The corresponding half live's in air, water, soil and sediment were 0.05, 15, 30 and 135 days respectively.
