- 41 mg/L
- Based on:
- formulation
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
Reference substance
- Reference substance:

- Parameter:
- % degradation (O2 consumption)
- Value:
- ca. 0
- Sampling time:
- 28 d
BOD5 / COD results
BOD5 / COD
- Parameter:
- COD
- Value:
- 1.26 other: mg/mg
- Results with reference substance:
- Not readily biodegradable
Applicant's summary and conclusion
- Conclusions:
- The percentage biodegradation of the test substance was 0% over 28d, so the test substance is considered not to be readily biodegradable under the conditions of the study presently performed
