- Based on:
- other: reference substance
- Remarks:
- Nominal concentration
- Details on study design:
- A measured volume of inoculated mineral medium, containing a known concentration of test substance as the nominal sole source of organic carbon, is stirred in a closed flask at a constant temperature (± 1°C) for up to 28 days. Evolved carbon dioxide is absorbed in sodium hydroxide pellets. The consumption of oxygen is determined by measuring the pressure drop in the respirometer flask. The Biological Oxygen Demand (BOD), amount of oxygen taken up by the microbial population during biodegradation of the test chemical (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD (Theoretical Oxygen Demand, calculated from the elemental composition, assuming that carbon is oxidized to carbon dioxide, hydrogen to water and nitrogen to ammonium, nitrite or nitrate).

- Degradation of the reference substance, Sodium Benzoate, attained 72% by Day 7 and 84% by Day 14.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Executive summary:
Folione undergoes 80% biodegradation after 28 days in the test conditions. The 10 -day window criterion is also fulfilled (29% biodegradation on day 5 and 71% on day 15).
Folione did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration.
Therefore, Folione should be regarded as readily biodegradable according to this test.
