Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The substance cannot be classified as ready biodegradable. The mean cumulative net percent CO2 evolved (percent biodegradation) from the aqueous test medium fortified with test substance at 10 mg C/L was -1.56% on day 28.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Based on the CO2 analysis results from this study, the test substance cannot be characterized as ‘readily biodegradable’ according to the OECD 301B guideline (does not reach 60% or greater CO2 evolution within a 10 -day window of exceeding 10% biodegradation).The rapid degradation of the reference substance confirmed the presence of an acceptable microbial community and confirmed system integrity.
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.
