Results and discussion
% Degradation
- Parameter:
- % degradation (CO2 evolution)
- Value:
- ca. 7 - <= 21
- Sampling time:
- 28 d
- Details on results:
- The temperature recorded in a vessel with water in the same room varied between 21.7 and 22.6 degree celsius with the pH values varying between 7.6 and 8.2.
BOD5 / COD results
- Results with reference substance:
- In the toxicity control more than 25% degradation occurred within 14 days. Therefore, the test substance was assumed to be not inhibitory on microbial activity.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- The test substance was not readily biodegradable under the conditions of the modified sturm test presently performed.
- Executive summary:
Not readily biodegradable
