Description of key information
The substance was considered not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Several studies investigating biodegradation potential of the substance under evaluation are available.
The inherent biodegradability of FAT 36152/F was evaluated in a 14 days MITI -Test (I) conducted according to the OECD Guideline for Testing of Chemicals, No. 301C and in compliance to GLP. The test substance was tested in a concentration of 100 mg/L. After 14 days, biodegradation of FAT 36152/F was 0 % indicating the test substance being non-biodegradable (1993).
In a GLP compliant study performed to determine the chemical oxygen demand of FAT 36152/F according to DEV DIN 38'409 - H 41-1 (1980) corresponding to 92/96/EE C C.6.A predeterminated amount of the test substance in water was oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate was determined by titration with standardized ferrous ammonium sulphate. The COD of FAT 36152/F was determined to be 1577 mg O2/g test mat. (1993).
In studies performed according to the EEC Directive, COD & BOD5 values were determined to be 417 mg O2/g test mat and 1275 mg O2/g test mat respectively (1990). Further, the BOD5/COD quotient calculated using data from the studies is equivalent to 0, indicating the test substance as not rapidly biodegradable.
50.65 % biodegradation (Adsorption 3h:16:35%) was observed in a 28 day biodegradation test performed as per OECD guideline 302B (1991).
OECD Guideline No 302B does not give any definitive pass levels for test items, however the “Summary of Considerations in the Report from the OECD Expert Group on Degradation and Accumulation” suggests that a figure of more than 20% biodegradation may be regarded as evidence for inherent, primary biodegradability. A figure of more than 70 % mineralisation may be regarded as evidence for ultimate biodegradation.
FAT 36152/D is found to be inherently biodegradable under the conditions of this test.
Several supporting studies performed to determine COD & BOD5 values for FAT 36152/A (1983) & FAT 36152/B (1986), showed the following results:
COD of FAT 36152/A: 1550 mg/g O2
BOD of FAT 36152/A: 27.5 mg/g O2
COD of FAT 36152/B: 974.7 mg/g O2
BOD5 of FAT 36152/B: 240 mg/g O2
Taking into consideration the data from key and supporting studies and the calculated BOD5/COD quotient from these studies which is not >0.5, the test substance FAT 36152 is considered to be not biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
