A predetermined amount of the test substance FAT 45082/G in water is oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate is determined by titration with standardized ferrous ammonium sulphate. The test substance was tested with a sample weight of 4.48 and 4.49 mg. The reference substance potassium hydrogen phthalate was tested with 20 mL of a 0.17 g/l solution. The COD of FAT 45082/G was determined to be 1789 mg O2/g, while the COD of the reference substance was 193 mg O2/l.

The test substance and the reference substance were tested in a concentration of about 69.50 mg ThOD/30 mg and 167 mg ThOD/100 mg, respectively. Mean value of the biodegradation of FAT 45082/G after 28 days: 7 %
Biodegradation of the reference substance after 28 days: 91 %
The biochemical oxygen demand (BOD5) after 5 days was: 50 mg O2/g
BAsed on the present study, it can be concluded that FAT 45082/G was found to be not inherently biodegradable as only 7 % biodegradation was observed after an incubation time of 28 days.

Description of key information
A study was performed to determine the inherent biodegradability of FAT 45082/G in a 28-day Modified MITI (II) - Test according to the OECD Guideline for Testing of Chemicals No. 302C (adopted 1981). The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations. The test substance and the reference substance were tested in a concentration of about 69.50 mg ThOD/30 mg and 167 mg ThOD/100 mg, respectively. Mean value of the biodegradation observed for FAT 45082/G after 28 days was 7 %, whereas biodegradation of the reference substance after 28 days was 91 %. The biochemical oxygen demand (BOD5) after 5 days was 50 mg O2/g. On the basis of the study results FAT 45082/G was found to be not inherently biodegradable after an incubation time of 28 days. Another key study which was carried according to DIN 38409- H 41-1 (1980) corresponding to EEC Directive 92/69/ C.6. (1992) showed COD of 1789 mg O2/g. Vat Black 65 was assessed for biodegradability over the years in the studies estimating BOD5 and COD:
FAT 45082/E- BOD5: 50 -100 mg/g O2; COD: 988.2 mg/g O2
FAT 45082/D- BOD5: 104 mg/g O2; COD: 1723 mg/g O2
FAT 45082/B- BOD5: 14 mg/g O2; COD: 1657 mg/g O2
In all these cases, the BOD5/COD quotient <0.5, therefore the substance is considered to be not readily biodegradable. Taking the data available into account, FAT 45082 is considered to be not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
