Applicant's summary and conclusion
- Conclusions:
- In this assay the biological removal of the substance is of 67.3% after 21 days. However results from tests simulating the condition in a sewage treatment plant (STP) cannot be used for assessing the degradation in the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
