Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Degradation of 41 % was determined for test substance within the test period of 28 d. Hence, test substance is classified as 'Not Readily Biodegradable'
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A study was performed to assess the ready biodegradability of test substance according to EU Method C.4-D. and OECD Guideline 301 F.
The test substance in a mineral medium was inoculated with secondary effluent and incubated for 28 d under aerobic conditions. During this period the biodegradation of the test substance was determined on the basis of reduction in DOC.
The test substance showed 41 % degradation after 28 d. Therefore, the test substance is classified as not readily biodegradable. The reference substance showed 89 % degradation after 14 d.
The test substance is classified as not readily biodegradable (Dr. Caspers, 2002).
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.
