Description of key information
87.5% degradation after 28 days, fulfilling 10-day window (OECD 301F, manometric respirometry test). The substance is therefore considered to be readily biodegradable.
Key value for chemical safety assessment
Additional information
A manometric respirometry test with Octadec-9-enedioic acid (EC 802-122-7) was conducted by Yanzhen (2015). The study was conducted according to GLP and OECD guideline 301F. Activated sludge was exposed to an initial test item concentration of 21 mg/L and O2-consumption was measured. 61.9% and 87.5% degradation were reached after 5 and 28 days, respectively. Thus, the pass level of >60% degradation within 10 days is fulfilled and the test item is considered to be readily biodegradable.
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.
