- Details on inoculum:
- The inoculum was from the activated sludge of the biological wastewater treatment plant in Abidos (64). The activated sludge obtained 1 week before seeding the flasks, was diluted to 400 mg/L of equivalent dry material, and stirred. Before seeding the flasks, the diluted activated sludge was filtered to 11 µm. The test medium was inoculated with 7.8 mL/L of filtered sludge.

- Remarks:
- see details in conclusions
- Conclusions:
- The following validity criteria were fulfilled:
- the difference of extremes of replicate values of the removal of test chemical at the plateau, at the end of the test, or at the end of the 10d-window, was less than 20%
- the oxygen consumption was < 1.5mg/L at 28d. The residual oxygen concentration in the test series was > 0.5mg/L
- in the toxicity control flasks, containing both the reference item and the test substance, the percentage biodegradation reached 38% after 28d. Since this value was higher than 25%, the test item is considered as not inhibitory for inoculum.
But the percentage degradation of the reference item didn't reach 70% by 14 days (52%) - Executive summary:
Under the test conditions, the percentage of biodegradation of Dinoramac S36 reached 58% at the end of the test (28 days). According to OECD guideline 301, the test item can nearly be considered as readily biodegradable. The test item did not inhibit the micoorganisms as shown by the toxicity control flask. The validity criteria were fulfilled except the degradation for the reference substance that didn't reach 70% after 14 days.

- Deviations:
- yes
- Remarks:
- acceptable deviations (see details below)
- Principles of method if other than guideline:
- The test has been performed according to a slightly modified test guideline:
- Instead of an effluent/extract/medium, activated sludge was used as an inoculum (see details in the Study Design section);
- Ammonium chloride was omitted from the medium to prevent nitrification;
- As the test substance is a poorly soluble substance in water, the test substance was first dissolved in dichloromethane (0.56 mL) then added to 2g silica gel (100-200 mesh) weighed in a glass petri dish. The solvent was allowed to evaporate by placing the petri dish in a vnetilated hood for 3 hours, and the entire contents were then transferred to the BOD bottle. Although no additional oxygen consumption is expected controls with silica gel were carried out as well. - GLP compliance:
- yes
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- Secondary activated sludge was obtained from the RZWI Nieuwgraaf in Duiven (1990-01-24). The RZWI Nieuwgraaf is an activated sludge plant treating predominantly domestic wastewater.
Instead of an effluent/extract/medium, activated sludge was used as an inoculum. The inoculum was taken from an activated sludge plant. The sludge was preconditioned to reduce the endogenous respiration rates. To precondition, the sludge (200 mg dry weight/L) was aerated for a period of seven days. The sludge was diluted to a concentration in the BOD bottles of 2 mg DW/L. - Duration of test (contact time):
- 28 d
- Initial conc.:
- 2 mg/L
- Based on:
- test mat.
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- Test bottles: the test was performed in 280 mL BOD (Biological Oxygen Demand) bottles.
Stock solutions: The sodium acetate was added to the bottles using a stock solution of 1 g/L. For the application of the test substance on silica gel, a stock solution of 1 g/L on dichloromethane was used.
The biochemical oxygen demand (BOD) of the test substance and sodium acetate were calculated from the oxygen concentrations in the bottles with and without test substance but with silica gel and the bottles with and without sodium acetate but without silica gel. - Reference substance:
- other: sodium acetate
- Test performance:
- The dissolved oxygen concentrations were determined electrochemically using a oxygen electrode and meter.
- Parameter:
- % degradation (O2 consumption)
- Value:
- 20
- Sampling time:
- 5 d
- Parameter:
- % degradation (O2 consumption)
- Value:
- 50
- Sampling time:
- 15 d
- Parameter:
- % degradation (O2 consumption)
- Value:
- 76
- Sampling time:
- 28 d
- Details on results:
- The test substance was biodegraded in the closed bottle test and thus is classified as readily biodegradable. The addition of silica gel in the closed bottle test reduced the concentration of the test substance. Due to this reduction, the biodegradation was probably not influenced by the test substance.
- Results with reference substance:
- Percentages biodegradation of sodium acetate in the closed bottle test:
73% after 5 days
88% after 15 days
90% after 28 days - Validity criteria fulfilled:
- yes
- Remarks:
- see details in the conclusions section
- Interpretation of results:
- readily biodegradable, but failing 10-day window
- Conclusions:
- The test substance was biodegraded 76% after 28 days and thus can be classified as readily biodegradable. Over 60% biodegradation was not achieved between day 5 and day 15. The test substance is a mixture and this is a surfactant, it can be degraded sequentially by a consortium of microorganisms (Van Ginkel, 1996). The degradation curve will therefore be the sum of a number of growth curves. The 10-day time window criterion was developed on the assumption that a testsubstance is degraded according to a “standard” growth curve in ready biodegradability tests. The time-window should be ignored as a pass fail criterion because of these scientific reasons.
The validity of the test is shown by the oxygen consumption in the control bottle with sodium acetate and an endogenous respiration of 0.6 mg/L. The pH pf the medium at the end of the test period was 7.4. - Executive summary:
A ready biodegradability test was performed according to OECD guideline 301D and GLP requirements in order to allow the measurement of the biodegradability of 1,3-Propanediamine,N-tallow-,diacetate in an aerobic aqueous medium. The test substance was biodegraded to 76% after 28 days. The validity criteria were fulfilled. The test substance can be considered as readily biodegradable.

(as described by: J. Blok, chemosphere 14, 1985, 1805-1820; EEC update of test methods C3 to C10 of Annex V DocXI/501/89).
The inoculum was taken from an activated sludge plant treating predominantly domestic waste water. The sludge was preconditioned to reduce endogenous respiration rates. To this end, the sludge (200 mg dry wt/liter) was aerated for a period of 7 days. The sludge was diluted to a concentration in the biochemical oxygen demand (BOD) bottles of 2 mg dry wt/liter.
Ammonium chloride was omitted from the medium to prevent nitrification
The test compound is a poorly soluble substance in water and therefore the test substance was first dissolved in dichloromethane. The test substance in dichloromethane was added to silica gel weighed in a glass petri dish. The solvent was allowed to evaporate by placing the petri dish in a ventilated hood, and the entire contents were then transferred to the BOD bottles. Although no additional oxygen consumption was expected, controls with silica gel were carried out as well.

N-tallow-diaminopropane should therefore be classified as readily biodegradable - Executive summary:
In order to assess ecotoxicological effects of chemicals, a ready biodegradability test is performed which allows the measurement of the biodegradability in an aerobic aqueous medium. N-tallow-diaminopropane is biodegraded (62%) in the closed tottle test (OECD guideline 301D) perfomed in confirmity with the OECD principles of Good I.atoratory Practices (GLP). Therefore, N-tallow-diaminopropane should be classified as readily biodegradable. In this test, the presence of silica gel in the bottles reduced the concentration of N-tallow-diaminopropane in the medium so that the toxicity of the test substance does not influence the biodegradation.

- endogenous respiration of 1.0 mg/l; total mineralization of reference compound 81% at day 14; >0.5 mg/l O2 in all the bottles during the test; differences duplicates <20% at end test
- Interpretation of results:
- readily biodegradable
- Conclusions:
- N-oleyl-1,3-diaminopropane is biodegraded 66% at day 28 in the Closed Bottle test and should therefore be classified as readily biodegradable. Over 60% biodegradation was not achieved within a period of 10 days immediately following the attainment of 10% biodegradation. N-oleyl-1,3-diaminopropane is a mixture of alkyl-1,3-diaminopropanes and primary alkylamines. Moreover surfactants such as alkyl-1,3-diaminopropanes are degraded sequentially by a consortium of microorganisms (vanGinkel 1996). The degradation curve will therefore be the sum of a number of growth
curves. The 10-day time window criterion was developed on the assumption that a test substance is degraded according to a “standard” growth curve in ready biodegradability tests. The time-window should be ignored as a pass fail criterion because of these scientific
reasons. - Executive summary:
In order to assess the biotic degradation, a ready biodegradability test was performed which allows the biodegradability to be measured in an aerobic aqueous medium. The ready biodegradability was determined in the Closed Bottle test performed according to slightly modified OECD, EU and ISO Test Guidelines, and in compliance with the OECD principles of Good Laboratory Practice. N-oleyl-1,3-diaminopropane in the presence of silica gel did not cause a reduction in the endogenous respiration. The test substance is therefore considered to be non-inhibitory to the inoculum. N-oleyl-1,3-diaminopropane was biodegraded 66% at day 28 in the Closed Bottle test. Hence this substance should be classified as readily biodegradable. The test is valid as shown by an endogenous respiration of 1.0 mg/L and by the total mineralization of the reference compound, sodium acetate. Sodium acetate was degraded 81% of its theoretical oxygen demand after 14 days. Finally, the most important criterion was met by oxygen concentrations >0.5 mg/L in all bottles during the test period.
