Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Interpretation of results:
under test conditions no biodegradation observed
Conclusions:
Based on the COD and BOD5 values found for the test item, the respective BOD5/COD quotient is close to zero, therefore, no biodegradeation is expected.
