- Executive summary:
In GLP-compliant study, ready biodegradability of FAT 40854/A in a Manometric Respirometry Test according to OECD 301 F and EU Method C.4-D. Test Species used was aerobic activated sludge (micro-organisms from a domestic wastewater treatment plant) was supplied by the sewage works of Darmstadt, Germany. The test item FAT 40854/A was investigated for its ready biodegradability in a manometric respirometry test over a period of 28 days. The biodegradation was followed by the oxygen uptake of the micro-organisms during exposure. As a reference item sodium benzoate was tested simultaneously under the same conditions as the test item and functioned as a procedure control. Degradation rate of test item calculated by the oxygen consumption of the aerobic activated sludge microorganisms after 28 days of incubation. Test item loading rate was 103 mg/L corresponding to an oxygen demand of about 85 mg/L (ThODNH4) and 85 mg/L (ThODNO3). The mean biodegradation after 28 days of FAT 40854/A was -12 % (ThODNH4) and (ThODNO3); the 10 day window criterion was not passed. The reference item sodium benzoate was sufficiently degraded to 80 % after 14 days and to 83 % after 28 days of incubation, thus confirming the suitability of the aerobic activated sludge inoculum used. Biodegradation of the toxicity control containing both, the test item and the reference item sodium benzoate, 56 % biodegradation was noted within 14 days and 56 % biodegradation after 28 days of incubation (ThODNH4) and (ThODNO3). Thus, the test item can be assumed to be not inhibitory to the aerobic activated sludge microorganisms. Based on the test results, FAT 40854/A is considered not to be readily biodegradable.

- The ratio of inoculum and aniline (as DOC) was 3:1.
Sampling and DOC analysis:
Prior to sampling the volume of the vessels was checked for evaporation and if necessary Milli-Q water was added. The medium was mixed thoroughly and a sample of ca. 100 mL was taken. This sample was passed through a rough paper filter (S&S 604), and thereafter through a 0.45 µm filter (S&S FP 030/0.45). At least, the first 5 mL was discarded. Duplicate samples of ca. 40 mL were then taken from the filtrate. All samples not analysed freshly were stored in a deep-freeze until analysis.
Frequency of sampling:
- At the start of the test (0 h) and 3h after addition of the test substance in order to estimate any adsorption of FAT 40854/A by the activated sludge;
- Day 1, 3, 7, 14, 21, 27 and 28.
Sample pretreatment:
- Day 1, 3, 7, 14, 21, 27 and 28: Not applicable, samples were analysed on the day of sampling.
- Day 14, reserve samples: Samples were stored in a freezer until analysis. Frozen samples were defrosted at room temperature. - Parameter:

- Value:
- 12
- Sampling time:
- 28 d
- Details on results:
- The results obtained during the test period showed no significant DOC removal in the first 3 hours of incubation in either of the test vessels indicating no or only limited adsorption to sludge during this period. The biodegradation values calculated from the DOC measurements performed during the 28-day test period revealed a maximum of 12 % biodegradation of FAT 40854/A. Thus, the biodegradation values did not reveal more than 20 % biodegradation of FAT 40854/A during the test period.
- Results with reference substance:
- The removal of aniline was at least 70 % within 14 days (98 %).
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- FAT 40854/A was not inherently biodegradable under the conditions of the 'Zahn-Wellens / EMPA Test' presently performed.
- Executive summary:
In a GLP-compliant study, the inherent biodegradability of FAT 40854/A was investigated in a 'Zahn-Wellens / EMPA Test' according to EU method C.9 and OECD 302B. At the start of the study the Dissolved Organic Carbon (DOC) concentration of the test solution containing FAT 40854/A (1.2138 g/l) was 241.2 mg/l and the DOC concentration of the reference solution containing Aniline (356.3 mg/l) was 273.7 mg/l. The ratio of inoculum and FAT 40854/A /aniline (as DOC) was 3:1.
The results obtained during the test period showed no significant DOC removal in the first 3 hours of incubation in any of the test vessels indicating no or only limited adsorption to sludge during this period. The biodegradation values calculated from the DOC measurements performed during the 28-day test period revealed a maximum of 12 % biodegradation of FAT 40854/A. Thus, the biodegradation values did not reveal more than 20 % biodegradation of FAT 40854/A during the test period. Since all acceptability criteria prescribed by the protocol were met, this study was considered to be valid. In conclusion, FAT 40854/A was not inherently biodegradable.

Biodegradation of Test Item
Percentage Biodegradation: The occurrence of nitrification was considered but not experimentally confirmed. The mean percentage biodegradation at the end of the 28-day exposure period was -12 % (ThODNH4) and (ThODNO3). The 10-day window was not passed. The degradation rate of FAT 40854/A did not reach 60 % within the 10-day window and after 28 days of incubation. According to the test guideline, FAT 40854/A is considered not to be readily biodegradable.
Biodegradation of Reference Item Sodium Benzoate
Percentage Biodegradation: The reference item sodium benzoate was sufficiently degraded to 80 % after 14 days and to 83 % after 28 days of incubation. The percentage biodegradation of the reference item confirms the suitability of the used aerobic activated sludge inoculum.
Biodegradation in the Toxicity Control
Percentage Biodegradation: In the toxicity control containing both the test item and reference 56 % biodegradation was noted within 14 days and 56 % biodegradation was determined after 28 days of incubation (ThODNH4) and (ThODNO3).
Conclusion: According to the test guidelines the test item can be assumed to be not inhibitory on the aerobic activated sludge microorganisms because degradation was >25 % within 14 days.

Oxygen Demand: The oxygen demand in the abiotic control was zero. No correction of the test item degradation rates had to be done.

Additional information
In aGLP-compliant study, ready biodegradability of FAT 40854/A was investigated in a Manometric Respirometry Test according to OECD 301 F and EU Method C.4-D using aerobic activated sludge over a period of 28 days. The mean biodegradation after 28 days of FAT 40854/A was -12 % (ThODNH4) and (ThODNO3); the 10-day window criterion was not passed. The reference item sodium benzoate was sufficiently degraded to 80 % after 14 days and to 83 % after 28 days of incubation, thus confirming the suitability of the aerobic activated sludge inoculum used. Biodegradation of the toxicity control containing both, the test item and the reference item sodium benzoate, 56 % biodegradation was noted within 14 days and 56 % biodegradation after 28 days of incubation (ThODNH4) and (ThODNO3). Thus, the test item can be assumed to be not inhibitory to the aerobic activated sludge microorganisms. Based on the test results, FAT 40854/A is considered not to be readily biodegradable. In another study, the inherent biodegradability of FAT 40854/A was investigated in a 'Zahn-Wellens / EMPA Test' according to EU method C.9, OECD 302B. The results obtained during the test period showed no significant DOC removal in the first 3 hours of incubation in any of the test vessels indicating no or only limited adsorption to sludge during this period. The biodegradation values calculated from the DOC measurements performed during the 28-day test period revealed a maximum of 12 % biodegradation of FAT 40854/A . Thus, the biodegradation values did not reveal more than 20 % biodegradation of FAT 40854/A during the test period. In conclusion, FAT 40854/A was not inherently biodegradable.
