The reference compound Aniline was biodegraded by an average of 77.4 % on exposure day 14, and reached an average biodegradation rate of 82.4 % by the end of the test (day 28). In the toxicity control, containing both FAT 40557/A and the reference compound Aniline, no inhibitory effect on the microorganisms was observed. Based on the test results, FAT 40557/A is not readily biodegradable. The test substance induced no inhibition of the activity of the microorganisms.

Referenceopen allclose all
The biochemical oxygen demand (BOD) in test flasks 2 and 3, containing FAT 40557/A at a concentration of 100 mg/I with respect to active ingredient, was 0 and 2 mg O2/1 (corrected for the mean BOD of the control flasks), respectively by the end of the 28-day test period. Expressed as percentage biodegradation, 0 and 1.6 % were noted by the end of the 28-day test period, resulting in a mean of 0.8 %. Therefore, FAT 40'557/A was found to be nonbiodegradable under the present test conditions.
The mean biochemical oxygen demand (BOD) of the test article after five days of exposure, corrected for the mean BOD of the control flasks, was 0 mg O2/1; therefore, the ratio BODs : COD = 0 : 80.2.
Chemical oxygen demand (COD):
The COD of the test substance was determined to be 80.2 mg O2/100 mg. The COD of the positive controls was determined to be 198.6 mg O2/L on average and no more than 10% of the oxidizing agent was used up in the blank controls.
Abiotic control:
The BOD of the Non inoculated flask containing the test substance and sterile test medium was 0 mg O2/L on exposure day 28. therefore, no abiotic degradation occurred throughout the 28-day exposure period.
Toxicity control:
The BOD of the toxicity control containing both test substance and the reference compound aniline showed a similar course of biodegradation over the 28-day exposure period as the two procedure controls containing the reference compound aniline only.

Additional information
The ready biodegradability of the test substance was determined in a GLP-compliant study according to OECD Guideline 301F (RCC, 1996). Biodegradation of the test substance was determined to be 0.8 % after 28 days and therefore it was concluded that the test substance was not readily biodegradable.
The inherent biodegradability of the test substance was determined in a GLP-compliant test according to OECD Guideline 302B (RCC, 1997). The biodegradation of the test substance ranged between 1 and 7 %. In another supporting inherent biodegradability study 0 % of biodegradation was seen in OECD guideline 302 B.
The biological oxygen demand (BOD5) was examined in a GLP-compliant study according to ISO 5815 (corresponding to EC method C.5) (CG 1996). The BOD5 of the test substance was found to be 0 mg O2/L. The chemical oxygen demand (COD) was examined in a GLP-compliant study according to DIN 38409- H 41-1 (corresponding to EC method C.6. (CG 1996). The COD of the test substance is 798 mg O2/L. The BOD5/COD ratio supports the conclusion that the test substance is not readily biodegradable.
