Description of key information
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- freshwater
Additional information
The substance was found to be not readily biodegradable in a standard OECD 301F respirometric test. At a test concentration of 100 mg/L the biodegradation degree (BOD of ThOD) was 0 – 10%.
