Results and discussion
Effect concentrationsopen allclose all
- Duration:
- 3 h
- Dose descriptor:
- IC50
- Effect conc.:
- > 1 000 mg/L
- Duration:
- 3 h
- Dose descriptor:
- NOEC
- Effect conc.:
- 1 000 mg/L
- Details on results:
- In the inhibition control of the degradation test at a test concentration of 2 mg/l an inhibition of 25 % after 15 resp. 28 d was observed.
Applicant's summary and conclusion
- Conclusions:
- Na-SOS did not exert any observable toxci effect on activated sludge miicroorganisms at all test concentrations and can therefore be regarded to be harmless to microorganisms
