Results and discussion

% Degradation
Key result
Remarks on result:
not readily biodegradable based on QSAR/QSPR prediction

Applicant's summary and conclusion

Interpretation of results:
not readily biodegradable
Conclusions:
The substance was predicted to be not readily biodegradable.
Executive summary:
