- % degradation (inorg. C analysis)
- Value:
- 93
- Sampling time:
- 28 d
- Details on results:
- Level of biodegradability > 60 % within 10 days.
BOD5 / COD results
- Results with reference substance:
- Percentage of average degradation > 60 % after 14 days of incubation.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The test item biodegradability is > 60% within 10 days in aerobic conditions. It is thus readily biodegradable.
