- Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 56.2 mg/L
- Based on:
- DOC

- Parameter:
- % degradation (DOC removal)
- Value:
- > 35
- Sampling time:
- 14 d
Any other information on results incl. tables
In the toxicity control, containing the test item, the reference item sodium benzoate and activated sludge (inoculum), the initial DOC decreased by 44% within 14 days of exposure. Thus, according to the test guidelines the test item can be assumed to not inhibitory to activated sludge because degradation was > 35% within 14days.
Applicant's summary and conclusion
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- The test substance was found not to be biodegradable under the conditions of the test.
