Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- ca. 3
- Sampling time:
- 28 d
- Remarks on result:
- not readily biodegradable based on QSAR/QSPR prediction
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- All validity criteria were met.
Degradation behaviour of positive control and toxicity control was normal. Abiotic degradation
was not observed. Both replicates of the test item showed good correspondence.
If degradation in the toxicity flask is below 25 % after 14 days, the test item can be considered
as toxic towards the inoculum. As degradation in the toxicity flask was 39.9 % after
14 days, the test item can be stated as “not toxic towards the inoculum in a concentration
of 42.1 mg/L”.
Ready degradability is defined in the guidelines as degradation surpassing 60% within 10
days after reaching a level of 10 %.
For the test item Solvent Red 119 only 3 % biodegradation was observed after 28 days.
The 10-day window could not be determined. The criterion of reaching 60% of degradation
is not met. Solvent Red 119 is therefore considered as “not readily biodegradable”.
Degradation missed 60% within 28 days, though. Therefore, the test item is considered as
“ not ultimately biodegradable within 28 days”, either.
No observations were made which might cause doubts concerning the validity of the study
outcome.
The result of the test can be considered valid. - Executive summary:
The test item Solvent Red 119 was tested using a concentration of nominally 20 mg organic
carbon/L (corresponding to 41.9 mg Solvent Red 119/L) in test medium following OECD
301B and EU-Method C.4-C.
Aniline was chosen as positive control.
Activated sludge was used as inoculum (concentration in the test 25.0 mg dry matter/L).
The test was left running for 28 days.
All validity criteria were met. Degradation of the positive control was 68 % after 8 days.
The following data were determined for the test item Solvent Red 119:
10-day-window: not detected
degradation at the end of 10-day-window: none
degradation at the end of the test: 3 %
pass level following guideline: 60 % at the end of 10-day-window for pure substances
respective 60 % at the end of the test for mixtures
For the test item Solvent Red 119 only 3 % biodegradation was observed after 28 days.
The 10-day window could not be determined. The criterion of reaching 60% of degradation
after 28 days is not met. Solvent Red 119 is therefore considered as “not readily biodegradable”.
As degradation missed 60% in the course of the test, Solvent Red 119 is considered as
not ultimately biodegradable within 28 days.
