Any other information on results incl. tables
The substance showed a BOD value of 4.8 mg oxygen/100 mg and 85.2 mg oxygen/100 mg for the BOD and COD, respectively. Based on these findings a BOD/COD-ratio of 0.42 was determined.
Applicant's summary and conclusion
- Conclusions:
- The BOD/COD-test was conducted with the analogue substance. Based on its BOD/COD-ratio of 0.05, the analogue substance is considered to be biologically degradable by about 5 %. Accordingly the analogue substance has to be regarded as "not readily biodegradable". Due to the structural similarity this has also to be concluded for the substance subject of registration.
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.
