Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- - Source of inoculum/activated sludge: Mixture of polyvalent bacteria (activated sludge) from the aeration tank of a domestic sewage treatment plant, ARA Pro Rheno Basel communal.
- Pretreatment: The activated sludge was washed 4 times with tap water and the last time with test medium. A sample of the activated sludge was taken to determine the dry weight of the Suspended Solids. An amount corresponding to 2 - 3 g per litre of suspended solids was mixed with test medium. The pre-treated sludge was aerated until use
- Concentration of sludge: 30 mg/L - Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 100 mg/L
- Based on:
- test mat.
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- TEST CONDITIONS
- Composition of medium: The test water was prepared according to the testing guidelines.
- Test temperature: 21°C
- pH: pH value of all incubation flasks was measured at the beginning and at the end of the test
- pH adjusted: no
- Continuous darkness: yes
TEST SYSTEM
- Test vessels: 500 mL conical vessels containing 250 mL test medium, continuously stirred
- Test apparatus: Voith Sapromat apparatus
- Number of culture flasks/concentration:
Test item: 2 vessels
Inoculum control: 2 vessels
Procedure control: 2 vessels
Abiotic sterile control: 1 vessel
Inhibition control: 1 vessel
Biochemical Oxygen Demand: measured continuously by means of a BOD-meter
Biodegradation: Calculated on the basis of the ThOD
Oxygen consumption: automatically measured by the test apparatus (Voith Sapromat)
STATISTICAL METHODS: not performed

- Results with reference substance:
- Points of degradation plot (reference substance):
38 % degradation after 2 d
59 % degradation after 5 d
83 % degradation after 16 d
86 % degradation after 22 d

Any other information on results incl. tables
The biodegradation of the test substance was determined as 55% after 28 days of incubation. The test item did not reach the pass level of 60% for ready biodegradability in the Manometric Respirometry Test neither within the 10-day window nor after 28 days of incubation. Therefore, the test substance cannot be assessed as readily biodegradable.
Applicant's summary and conclusion
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.
