Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)

Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, adapted
- Details on inoculum:
- Activated sludge from a biologic sewage treatment plant was used. The chosen plant is treating mostly domestic sewage.
Source and Pre-Treatment:
Source:
The sludge was taken from the activation basin of the ESN (Stadtentsorgung Neustadt) sewage treatment plant, Im Altenschemel, NW-Lachen-Speyerdorf.
Date of collection:
13. Jan. 2012, batch no: 20120113.
Pre-Treatment:
The sludge was filtrated, washed with tap water twice, then washed with and re-sus-pended in test medium. It was then aerated for > 12 hours. The dry matter was determined with 4420 mg suspended solids/litre. - Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 20 mg/L
- Based on:
- DOC
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Details on study design:
- The test vessels were aerated with purified (by activated charcoal), C02-scrubbed, moistened air. The scrubbing of carbon dioxide was achieved by bubbling the purified air through a flask containing 1.5 m-NaOH. To control the absence of C02, the air was then led through a flask containing a solution of Ba(OH)2 before reaching the test vessels.
Magnetic stirrers were used to prevent deposition of inoculum.
The emitted C02 was trapped in 0.25-m-NaC)H. Two scrubbers containing 100 mL each were connected in series to the test vessels. The initial IC value of the 0.25 m-NaOH was separately determined in each flask.
From each front scrubber flask, ten samples were taken in order to determine the emitted C02. (on days 0, 2, 4, 7, 9, 11, 14, 18, 23 and 29). The sample volume was 1 mL. The resulting change in the volume of the front flask was considered in the calculation of emitted C02 (see also chapter 8.2.1).
On day 28, 5 mL HCI 2-m. were added to each test flask in order to drive off dissolved C02. On day 29, samples from both scrubber flasks were taken.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- Ukanol FR 70 is not readily biodegradable following OECD 301B/EU C.4-C.
- Executive summary:
The test item Ukanol FR 70 was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 34.1 mg Ukanol FR 70/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 mg dry matter/L). The test was left running for 28 days. All validity criteria were met. Degradation of the positive control was 66 % after eleven days. The following data were determined for the test item Ukanol FR 70: 10-day-window: not detected
degradation at the end of 10-day-window: none
degradation at the end of the test: 4 %
pass level following guideline: 60% at the end of 10-day-window
Therefore, regardless of the 10-day-window, Ukanol FR 70 is not readily biodegradable following OECD 301B/EU C.4-C.
