Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is inorganic
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVINGAccording to column 2 of Annex VII (standard information requirements for substances manufactured or imported in quantities of 1 tonne or more per year) of Regulation (EC) No 1907/2006 a study to determine ready biodegradability does not need to be conducted if the substance is inorganic. Lutetium-yttrium oxyorthosilicate, cerium doped is a stable inorganic compound which is manufactured by smelting of the underlying metal oxides. Due to the strictly inorganic character of the substance, a study to determine the ready biodegradability does not need to be conducted under Regulation (EC) No 1907/2006 (REACH).

Additional information
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.
