Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Screening for ready biodegradability was performed by the closed bottle test.
(-)-Beta-pinene is readily biodegradable according to the criteria of the OECD 301 guideline.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Key study conducted according to OECD 301 D Guideline and GLP without deviation.
(-)-Beta-Pinene was tested at a concentration of 2 mg/L. The inoculum was domestic activated sewage sludge. Degradation was assessed by measurement of oxygen consumption.
The pass level for ready biodegradability was reached in the required time window within the 28-d period of the test: 76% biodegradation on Day 28. This result can be used as key value for chemical safety assessment.Alpha pinene and delta 3 carene, which are structurally similar compounds, were also found to be readily biodegradable according to OECD 301 criteria.
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.
