Reference
Description of key information
not readily biodegradable: 2.1% after 28 d
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
There is one study available, which investigated the biodegradation of the test substance in water according to OECD 301C. Microorganisms were inoculated with 100 mg/L test substance in closed bottles for two weeks and oxygen consumption as well as GC/FID was followed to estimate biodegradation.
After two weeks the test substance was degraded by 2.1% based on analysis of the test substance and 0% based on O2 consumption. Therefore, it was concluded that the test substance is not readily biodegradable according to the OECD criteria.
