Description of key information
2 -EHA is readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In a manometric respirometry test conducted according to EU Method C.4-D (comparable to OECD guideline 301 F) biodegradation (BOD/ThOD) of 2-EHA of 70 - 80 % after 15 days was found (BASF AG 1988). The 10-day window criterion was fulfilled. As inoculum domestic activated sludge was used. Thus, under the conditions of the test, 2 -EHA was readily biodegradable.
A MITI-I test performed according to OECD 301C confirmed this result (JETOC/CITI 1992).
Based on the available test results, 2-EHA has to be regarded as 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.
