Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In the key study, after 28 days, the mean of degradabilities by BOD measurement was 85%, the mean of degradabilities by DOC measurement was 96%, and all of the disappearance rates of the test substance were more than or equal to 98%, all leading to the judgment that the test substance is readily biodegradable (Mitsubishi Chemical Safety Institute, 2001).
A Pseudomonas sp. strain was isolated by enrichment culture from soil using 2,3-dichloro-propanol-1 as the sole carbon source.
> 99 % degradation occured after 24 hours. Therefore the substance is considered readily biodegradable. (Castro, C.E. & Bartnicki, E.W., 1968)
In one strain, an inducible epoxide hydrase using glycidol as substrate was detected in 40000 g crude supernatants from bacterial extracts. Enzyme activity (30 degree C, pH 7.5, 5 mM glycidol): bacteria grown on epichlorohydrin 107 U/ g prot., grown on glycidol 817 U/g prot. Glycerol was identified as hydrolysis product (van den Wijngaard, A.J. et al., J., 1989).
Therefore, 2,3-epoxypropan-1-ol is 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.
