Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Per multiple guideline tests, greater than 60 percent of 1,4-butanediol biodegraded in less than 7 days.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
Guideline study results indicate the 1,4 -butanediol (BDO) undergoes rapid biodegradation in water. In an OECD 301C guideline study, BDO was readily biodegradable (METI, 1992) and, in an OECD 302B guideline study, BDO biodegraded rapidly and completely such that it can be classified as readily biodegradable (BASF, 1977).
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.
