Initial test substance concentration
- Initial conc.:
- 100 mg/L
- Based on:
- other: nominal sol source of organic carbon
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
- Remarks:
- ThOD
- Details on study design:
- The test was performed on a measured volume of inoculated mineral medium (250mL), containing the test item at 10 mg/L (directly added in flask after a period of 20 minutes of ultrasonication) as the nomila sol source of organic carbon and stirred in closed flasks at a constant temperature (20+/- 1°C) for up to 28 days.
Microbial respiration consumes O2 and releases CO2 which is absorbed by soda lime pellets present in the haedspace of flasks. This produces a decrease in pressure in the flask proportional to the amount of oxygen taken up by the microbial population during biodegradation, which was expressed as a percentage of ThOD (Theoretical Oxygen Demand).
Allowance was made for the endogenous activity of the inoculum by running parallel blancks with inoculum but without test item. Furthemore, in order to check the procedure, a reference compounds control (sodium benzote + inoculum) and a toxicity control (sodium benzoate + inoculum + test item) were run in parallel.
This test was performed in duplicate for the test item. pH of the contents was measured at the start and the end of the experiment.
The oxygen consumption is recorded every 112 minutes for each flask
Reference substance

Results and discussion
- Preliminary study:
- No data
- Test performance:
- All validity criteria given by the OECD 301F guideline were respected:
Oxygen uptake of the inoculum control was not greater than 60 mg/L
Variation between the two test item replicates was inferior to 20% at the end of the test
reference item showed a biodegradability superior to 60% within 14 days
pH values were comprised between 6 and 8.5

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The substance is readily biodegradable.
- Executive summary:
Readly biodegradability of the test item "2237 JG" was performed according to the OECD 301F guideline. The results obtained show that the test item biodegradability reached at the end of the sudy (i.e. 28 days), the 60% pass level was not reached in a 10 days windows.Because the substance is a UVCB and according to paragraph 4.1.2.9.5 of the regulation 286/2011 amending the CLP regulation 1272/2008, the 10 -day window does not have to be taken into account for this kind of substance. Therefore the substance is ready biodegradable.
