Description of key information
Total organic carbon (TOC) of Reactive Red 065 was found to be 31 % after 31 days. The BOD5 was fond to be 42 mg O2/g while COD was 688 mg O2/g; so the BOD5/COD ratio calculated as 0.06. Based on this value Reactive Red 065 should be considered as not biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
- Type of water:
- freshwater
