% Degradation
Parameter:
not specified
Value:
1
Sampling time:
28 d
Details on results:
The test material achieved only 1% biodegradation after 28 days and therefore can not be classed as readily biodegradable.

BOD5 / COD results

Results with reference substance:
The reference substance achieved 75% degradation after 12 days and 88% degradation after 28 days.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Interpretation of results:
other: not readily biodegradable
Conclusions:
The test material only achieved 1% biodegradation after 28 days and therefore can not be considered as readily biodegradable. The reference material achieved 88% degradation after 28 days, these results are considered valid.
Executive summary:

The study was conducted according to OECD guideline No. 301C. The test material achieved 1% biodegradation after 28 days and therefore can not be considered as readily biodegradable. The reference material achieved 88% degradation after 28 days, these results are considered valid.
