BOD5 / COD results
- Results with reference substance:
- Degradation of sodium benzoate exceeded 40% after 7 days and 65% after 14 days: the activity of the inoculum was thus verified (validity criterion).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The Ready Biodegradability of Citronellyl Oxyacetaldehyde was determined by the Manometric Respirometry Test.
Citronellyl Oxyacetaldehyde undergoes 79% biodegradation after 28 days in the test conditions. The 10-day window criterion is also fulfilled (19% biodegradation on day 4 and 72% on day 14).
Citronellyl Oxyacetaldehyde 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. - Executive summary:
The Ready Biodegradability of Citronellyl Oxyacetaldehyde was determined by the Manometric Respirometry Test.
Citronellyl Oxyacetaldehyde undergoes 79% biodegradation after 28 days in the test conditions.The 10-day window criterion is also fulfilled (19% biodegradation on day 4 and 72% on day 14).
Citronellyl Oxyacetaldehyde 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.
Thus, Citronellyl Oxyacetaldehyde should be regarded as readily biodegradable according to this test.
