Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The test item attained a mean degradation value of 88% degradation after 28 days and satisfied the 10 day window validation criterion. The test item can therefore be considered to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
A reliable study was performed in accordance with GLP and OECD Guideline 301F to assess the ready biodegradability of 9-dodecenoic acid, methyl ester in an aerobic aqueous media and soil/sediment. The test item, at a concentration of 100 mg/L was exposed to inoculum consisting of sewage treatment microorganisms and soil/sediment filtrate with mineral medium in sealed culture vessels in diffuse light at 21 ± 1 °C for 28 days.
The degradation of the test item was assessed by measurement of daily oxygen consumption values. Control solutions with inoculum and the reference item, aniline, together with a toxicity control were used for validation purposes.
The test item attained a mean degradation value of 88% degradation after 28 days and satisfied the 10 day window validation criterion. 9-dodecenoic acid, methyl ester is therefore 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.
