A predeterminated amount of the test substance FAT 92368/A dissolved 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 concentration was tested in 5.0 mg/l. The reference substance Potassium hydrogen phthalate solution was tested in a concentration of 20 mL/L.

Description of key information
Acid Yellow 220 can be considered to be not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
By the nature of their design and use, textile dyes are not intended to be readily biodegradable as this would assist in the rapid destruction of the dyestuff, rendering it unfit for purpose. There are ISO, European, American (AATCC) and national standards for the colour fastness of dyes. Dyes are required to have specific fastness properties. If the dyes were biodegradable, it would not be possible for them to have these fastness properties. As such, it is accepted that such substances are not readily biodegradable under relevant environmental conditions. A published study (Pagga & Brown, 1986) describes the results of the testing of 87 dyestuffs in short-term aerobic biodegradation tests. The authors of this publication concluded that dyestuffs are very unlikely to show any significant biodegradation in such tests and that 'there seems little point in carrying out such test procedures’ on dyestuffs. Nevertheless, biodegradability of Acid Yellow 220 was tested over the years in several Zahn Wellens tests as well as tests evaluating Biological Oxygen Demand (BOD5) and Chemical Oxygen Demand (COD). In the most recent Zahn Wellens Test (1993) designated as key study, the elimination observed was 0.3 %. Similarly in the studies determining BOD5 and COD (1993), the BOD5/COD ratio was 0/892 equalling 0. Several other studies indicated BOD5/COD ratio to be equalling 0. Hence, Acid Yellow 220 should regarded as not readily biodegradable.
