Water quality-Evaluation in an aqueous medium of the ultimate aerobic biodegradability of organic compounds - Determination of biochemical oxygen demand in a two-phase closed bottle test.
The test method used is based on OECD test method 301D and the RDA-Blok-Test. Mineral medium was inoculated with activated sludge and stabilized for one week at 18-22 C with continuous stirring. After stabilisation, 200 ml of test medium was filled into 300 ml bottles, aerated until O2 saturation was reached and spiked with test substance by directly weighing into the test vessels.
Vessels were filled 2/3, stoppered and shaken continuously at 18-22 C. Degradation was followed by weekly measurements of BOD using an O2-electrode. Oxygen consumption resulting from biodegradation of the test substance was corrected by oxygen uptake of blank inoculum. Degradation rate was calculated as % BOD/ThOD. - GLP compliance:

Ready Biodegradability Prediction: (YES or NO)
----------------------------------------------
Criteria for the YES or NO prediction: If the Biowin3 (ultimate survey
model) result is "weeks" or faster (i.e. "days", "days to weeks", or
"weeks" AND the Biowin5 (MITI linear model) probability is >= 0.5, then
the prediction is YES (readily biodegradable). If this condition is not
satisfied, the prediction is NO (not readily biodegradable). This method
is based on application of Bayesian analysis to ready biodegradation data
(see Help). Biowin5 and 6 also predict ready biodegradability, but for
degradation in the OECD301C test only; using data from the Chemicals
Evaluation and Research Institute Japan (CERIJ) database.
Two concentrations of effluent were tested:
5 ml/l and 50 ml/l. In the results section, the first value cited is for the 5 ml/l concentration and the second set refers to the 50ml/l concentration.The test substance degraded >60% over the test period, meeting the 10 day window criterion, therefore it is considered readily biodegradable..

Description of key information
Biodegradation in water:screening tests
Data of following studies are demonstrating rapid biodegradation Alcohols, C12-14 under aerobic conditions.
Henkel KGaA. , 1997 conducted BOD-test for Insoluble Substances (BODIS); ISO 10708 for Biodegradation of Alcohols, C12-14.
The test method used is based on OECD test method 301D and the RDA-Blok-Test. Mineral medium was inoculated with activated sludge and stabilized for one week at 18-22 C with continuous stirring. After stabilisation, 200 ml of test medium was filled into 300 ml bottles, aerated until O2 saturation was reached and spiked with test substance by directly weighing into the test vessels.
Degradation was 79 - 97 % after 28 day(s), the substance is considered to be readily biodegradable
The BIOWIN QSAR predicts that the substance Alcohols, C12-14 will be readily biodegradable.
Richterich , 1993 conducted OECD 301D test for Biodegradation of Alcohols, C12 (1-Dodecanol). Degradation was 79 % after 28 day(s) , the substance is considered to be readily biodegradable. Dodecan-1-ol (C12) is supporting substance for Alcohols, C12-C14 and the main component. The test substance (2 mg/l) attained >60% degradation during the 14 day window.
Henkel KGaA. , 1992 conducted OECD test method 301D and BOD-test for Insoluble Substances (BODIS); ISO 10708 for Biodegradation of Dodecan-1-ol (C12. Degradation was 100 % after 28 day(s) , the substance is considered to be readily biodegradable.
The substance degraded >60% in the 10 day window. .Dodecan-1-ol (C12) is supporting substance for Alcohols, C12-C14 and the main component.
Morris, P.A., Filler, P.A., and Nielsen, A.M. (1991) conducted OECD 301B test and Degradationwas 71 % after 28 day(s) , the substance is considered to be readily biodegradable. The substance degraded >60% in the 14 day window. .Dodecan-1-ol (C12) is supporting substance for Alcohols,C12-C14 and the main component.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Biodegradation in water:screening tests
Data of following studies are demonstrating rapid biodegradation Alcohols, C12-14 under aerobic conditions.
Henkel KGaA. , 1997 conducted BOD-test for Insoluble Substances (BODIS); ISO 10708 for Biodegradation of Alcohols, C12-14.
The test method used is based on OECD test method 301D and the RDA-Blok-Test. Mineral medium was inoculated with activated sludge and stabilized for one week at 18-22 C with continuous stirring. After stabilisation, 200 ml of test medium was filled into 300 ml bottles, aerated until O2 saturation was reached and spiked with test substance by directly weighing into the test vessels.
