Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Details on inoculum:
- Activated sludge sampled from the domestic water treatment plant "Louis Fargue" in Bordeaux on 9 January 2002. The sludge was prepared by filtration through a 0.5 mm sieve, then decanted into a mineral medium to decrease the dissolved organic carbon content. The activated sludge was aerated for 6 days and in accordance with the laboratory's own standard operating procedure MOP 5409/03 70 66 07.
Physico-chemical properties of the inoculum were reported as:
Suspended solids: 3.1 g/l
pH: 5.5
Dissolved oxygen: 7.6 mg/l - Duration of test (contact time):
- 28 d
Initial test substance concentrationopen allclose all
- Initial conc.:

- Initial conc.:

- Based on:

Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- Two test substance concentrations were used at 10 and 20 mg/l. An inoculum blank control and a positive control (sodium benzoate) were also established to measure the experimental conditions. The study was run in the dark at 20 degrees C +/- 1 degree C. Two replicates of each test substance concentration were used.
Reference substance
- Reference substance:
- benzoic acid, sodium salt
Results and discussion
- Preliminary study:
- No data
- Test performance:
- The test met the validity criteria for the following parameters:
- oxygen uptake (< 60 mg/l);
- variation between the two 10 mg/l replicates was < 20% at the end of the test
- reference substance showed biodegradability > 60% within 14 days
- 10 mg/l toxicity control biodegradation was > 25% within 14 days

- Sampling time:

- Remarks on result:
- other: not readily biodegradable
- Remarks:
- 20 mg/l test substance
- Details on results:
- The test substance as 10 mg/l is relied upon as the key result, which reported biodegradation at 21.1% after 28 days (average of two replicates). The test concentration at 20 mg/l is considered by the laboratory to have indicated a slight toxic effect at this concentration and the resulting biodegradation of 8% (average of two replicates) is not relied upon for further assessment.
BOD5 / COD results
- Results with reference substance:
- The positive controls (sodium benzoate) were reported as 77.3% and 57.1% in the 10 mgl and 20 mg/l, respectively, at day 14.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The test substance (10 mg/l) was incubated with domestic activated sludge for 28 days and achieved 21.1% biodegradation. The substance is not classified as readily biodegradable, but some degradation did occur.
- Executive summary:
The biodegradation of the test substance (at 10 mg/l) was assessed in a reliable OECD 301F Guideline study through the measurement of oxygen consumption when mixed with domestic activated sludge. After 28 days test duration, the test substance had degraded by 21.1% and is considered to be not readily biodegradable, although some degradation did occur.
