Readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One valid key study is available to assess the biodegradation of γ-decalactone. This study was performed in an aerobic aqueous media, according to OECD Guideline 301F. γ-decalactone was exposed to activated sewage sludge micro-organisms at a concentration of 100 mg/L with culture medium in a sealed culture flask at 22°C for 28 days. The degradation of γ-decalactone was assessed by the measurement of oxygen consumption daily. Control solutions with inoculum and the reference substance, aniline, together with a toxicity control were used for validation purposes. γ-decalactone attained 82% degradation after 28 days, meeting the 10-day window.
In conclusion, γ-decalactone is considered 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.
