Results and discussion

% Degradation
Key result
Parameter:
% degradation (O2 consumption)
Value:
3
St. dev.:
0.01
Remarks on result:
not readily biodegradable based on QSAR/QSPR prediction

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Interpretation of results:
not readily biodegradable
Conclusions:
3% degradation was predicted
Executive summary:

The catalogic model for biodegradation was used within the QSAR Toolbox. 3% degradation based on BOD was predicted indicating the test substance is not readily biodegradable. Additional supporting documentation is provided in the prediction report attached in IUCLID.
