Applicant's summary and conclusion
- Interpretation of results:
- under test conditions no biodegradation observed
- Executive summary:
The closed bottle test (OECD 301D) was conducted by the BAYER AG.
Tested concentrations were in a range up to 80 mg/L, the test duration was 28 days, the inoculum consisted of non adapted, activated sludge.
The test showed after 28 days 0% degradation. Therefore, 3,4 -DCA is regarded as non readily biodegradable in surface waters.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
