Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The substance is to be considered as readily biodegradable because the biodegradation reached 75% within 28 days, and the 14 -day window was met.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One study is available assessing the biodegradation of the test item in water. The study was performed according to 92/69/EEC method C.4-E and GLP. Even though there is limited information available on the study description, the results can be used for this endpoint in a conclusive manner.
As indicated in the OECD guideline 301 the value obtained in a 14-d window is accepted in the Closed Bottle method if it is considered that the number of bottles necessary to evaluate the 10-d window causes the test to become too unwieldy. Therefore, the substance is to be considered as readily biodegradable because the 14-day window was reached. The biodegradation was 75% in 28 days.
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.
