Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The ready biodegradation of the test item was determined in a study according to OECD guideline 301 B. The degree of biodegradation was < 10 % CO2/ThCO2 after an exposure period of 28 days. The test item was not readily biodegradable under the conditions of this test.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The ready biodegradation of the test item was determined in a study according to OECD guideline 301 B. The test substance was tested in a concentration of 20 mg/L TOC nominal, equivalent to approximately 44 mg/L. Activated sludge from the municipal sewage plant Mannheim was used as inoculum. The degree of biodegradation was < 10 % CO2/ThCO2 after an exposure period of 28 days. The test item was not readily biodegradable under the conditions of this test. The required pass level for readily biodegradability within a ten days window was not reached. The results in this study are consistent with all validity criteria and the test is valid according to the test guideline of this study. No deviations from the test guidelines or other incidents occurred during the course of the reported test, which may have influenced the results.
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.
