Additional information on environmental fate and behaviour
Administrative data
- Endpoint:
- additional information on environmental fate and behaviour
- Type of information:
- experimental study planned
- Study period:
- 2019-2020
- Justification for type of information:
- In the original draft decision, ECHA indicated that the identification of degradation products should be assessed via the OECD 309 approach. However, the Registrant instead to adapt this requirement in accordance with the requirements of Annex XI and instead proposes to use the EAWAG-BBD Pathway Prediction System, which predicts plausible pathways for microbial degradation of chemical compounds (the predictions use biotransformation rules), to identify potential breakdown products of the substance. If appropriate, and bearing in mind ECHA’s comment with regards to the need to assess the degradation products for their PBT/vPvB properties, subsequent analysis of these potential metabolites will be investigated using suitable QSAR such as the Biowin v.4.10, BCFBAF v.3.01 and ECOSAR v.1.11 Q(SAR) models within the EPISUITE software (v. 4.11 US EPA 2012), T.E.S.T. v. 4.1 and VEGA v.1.1.1 models and screened for PBT criteria.

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.
