Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- - Source of inoculum/activated sludge (e.g. location, sampling depth, contamination history, procedure): Activated sludge was collected from a sewage treatment works A-2500 Baden, which waste-water catchment is predominantly domestic. On arrival in the laboratory, the sample was aerated by means of a filtered compressed air before being used for the study.
The suspended solids concentration was determined by filtering a 5 mL sample through a pre-dried and pre-weighed glass filter (Whatman GF/C). The filter with solids were dried at 105 °C and re-weighed and the sludge solids determined by difference.
The inoculum was not acclimatised or adapted to "DIETHYLMALEINATE" before exposure to the test substance in this study. TThe concentration of the final suspended solids of the sludge in all vessels was nominally about 15 mg/L. - Duration of test (contact time):
- 28 d

- TEST CONDITIONS
- Composition of medium: mineral medium as described in the guideline.
- Additional substrate: none.
- Solubilising agent (type and concentration if used): none.
- Test temperature: mean 22.7 °C.
- pH: the pH of the media was between 7.2 and 7.9 , for details see additional background material: Key. Ipser 2010. Carbon Dioxide Evolution Test for Ready Biodegradability Tables and figures.pdf

- Suspended solids concentration: 15 mg/L.
- Continuous darkness: yes.
TEST SYSTEM
- Culturing apparatus: 5 L flasks.
- Number of culture flasks/concentration: 2 negative control flasks, 2 test substance flasks, 1 positive control flask, 1 toxicity control flask.
- Method used to create aerobic conditions: Apparatus for carbon dioxide scrubbing and a mixture of CO2-free oxygen and CO2-free nitrogen, from gas cylinders, in the correct proportions (20 % O2: 80 % N2) were used.
- Test performed in closed vessels.
SAMPLING
- Sampling frequency: The CO2 evolution was determined on Days 1, 3, 6, 8, 10, 14, 17, 22, 27 and 28/29.
Day 0 was the day of the addition of the test substance to the medium.

- Details on results:
- In this test the carbon dioxide evolution from "ALUMINIUM TRIFORMATE" with a nominal concentration of 15 mg carbon/L reached a maximum of 84.9 % after 28 days of incubation. More than 60 % biodegradation was obtained within the 10 d window which started at about Day 4.

BOD5 / COD results
- Results with reference substance:
- Positive control: The plateau of biodegradation was reached on about Day 10 and the degradation of the positive reference substance sodium benzoate exceeded the pass level of 60 % on about Day 8. The theoretical CO2 production of the positive control reached 69.5% on day 14. The test is considered to be valid.
Toxicity control: Degradation in the toxicity control, which contained sodium benzoate and the test substance, was not indicative of an inhibition of the microbial activity by the test substance. The final biodegradation was 67.1 %.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Aim and methods:
The biodegradability of "ALUMINIUM TRIFORMATE" was analysed by the determination of carbon dioxide evolution at frequent intervals over a 28 day period.
The method used was that described in Part C.4-C of the Regulation (EC) 440/2008 and in the OECD Guideline 301B.
Results:
• The reference substance sodium benzoate was degraded by 69.5 % within 14 days.
• Degradation in the toxicity control, which contained sodium benzoate and the test substance, was not indicative of an inhibition of the microbial activity by the test substance.
• The carbon dioxide evolution from "ALUMINIUM TRIFORMATE" with a nominal concentration of 15 mg carbon/L reached a maximum of 84.9 % after 28 days of incubation. More than 60 % biodegradation was obtained within the 10 d window which started at about Day 4.
Classification:
According to the Guidelines a substance giving a result greater than 60 % degradation within a 10-d window within 28 days is regarded as "readily biodegradable".
According to the results of this study, "ALUMINIUM TRIFORMATE" can therefore be classified as readily biodegradable. - Executive summary:
