Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 1997
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Read Across justified because structure is nearly the same. Only the chain length differ (C6:2 origin, C8:2 analogue substance). Read across justification is supported by the comparable phys.chem. data.

Perfluorooctylethyliodide (8-2 FTI) CASNo. 2043-53-0
The ready biodegradability of Perfluorooctylethyliodide was investigated in an OECD 301B test (Sturm test). After 28 days less than 6 % CO2 was formed. Due to the test setting the volatile test substance may have disappeard from the test solution and may not be present over the whole test period (no substance specific analysis was applied) (Hoechst, 1997).
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).
