Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- 0
- Sampling time:
- 28 d
Any other information on results incl. tables
The degradation of sodium acetate was not affacted by the presence of the test substance, so the non-occurrence of biodegradation was not caused by toxic effects of the test substance on the inoculum.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- no
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The biological degradation of the substance was investigated in a study according to OECD 301 B (modified Sturm test). The substance was found to be not readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
