Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- other: not readily biodegradable
- Conclusions:
- BOD5 is found to be 0 mg O2/g.
- Executive summary:
BOD5 of FAT 20242/E was determined according to in house Ciba Geigy Methode A.15, which is comparable to internationally accepted guidelines. Based on these investigations, the BOD5 of test substance was found to be 0 mg O2/g.
Considering the COD value determined with the test substance which is 1337 mg O2/g, the resulting BOD5/COD quotient is also zero, indicating that the test substance is unlikely to be biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
