Description of key information
Melonal underwent 75% biodegradation after 28 days in the key ready biodegradability study. The 10-day window criterion was also fulfilled.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The Ready Biodegradability of Melonal has been determined in two ready biodegradability tests (Rudio 2000, Kreutzer 2012). Both are GLP studies, performed according to the Manometric Respirometry OECD 301F Test. The level of degradation achieved after 28 days was 68% and 75% respectively, which exceeds the pass level of 60% theoretical oxygen demand. The 10 day window criterion was not quite met in the first study (Rudio 2000, onset of degradation on day 3, 51% on day 13),which was performed at a high test concentration of 100mg/L. However, it was fulfilled in the second study, which was performed at 20 mg/L (Kreutzer 2012; 33% biodegradation on day 3 and 68% on day 13).Thus, Melonal should be regarded as readily biodegradable.
An inhibition control was included in the Rudio 2000 ready biodegradability test. At the concentration used in the test (100 mg/l), Melonal was not inhibitory to the micro-organisms. This concentration can be considered as a NOEC for the toxicity to STP microorganisms.
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).
