Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- Within 28 days, a degradation of 1 % was determined for Bayticol P acid.
Bayticol P acid is considered to be "Not Readily Biodegradable".
All validity criteria of the test method were met:
The reference substance has reached the level for ready biodegradability by 14 days.
No toxicity of the test item was observed in the toxicity control.
The difference of extremes of replicate values of the removal of test chemical at the end of the test is less than 20 %.
Oxygen depletion in the inoculum blank did not exceed 1.5 mg/L dissolved oxygen after 28 days.
