Description of key information
For Acid Red 211 only few data on biodegradation in water are available to cover this endpoint. Among these two studies were selected as key study to cover this endpoint. FAT 20028/B was investigated to determine the biological oxygen demand (BOD5) and the chemical oxygen demand (COD). BOD5of FAT 20028/B was found to be 80 mg/g O2and COD was found to be 1071.24 mg/g O2. The corresponding BOD5/COD quotient can be calculated to 0.077, which demonstrates the substance to be not biodegradable.In another supporting study with FAT 20028/A, the inherent elimination after 21 days is 71 %. Additionally, few supporting studies available also consider the substance to be not biodegradable. Therefore, based on the biodegradation in water -screening tests, Acid Red 211 was considered as non-biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
- Type of water:
- freshwater
