Key result
Parameter:
% degradation (CO2 evolution)
Value:

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.
