- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
This read-across is based on the hypothesis that the source and the target substance have very similar physicochemical and (eco)toxicological properties because their chemical structures are nearly identical. An analogue approach has thus been employed. The target substance is the meta-isomer of the dye Reactive Yellow 095, where the sulphonate group is bound at the meta-position of the amino benzene moiety. The source chemical is the reaction mass of both the meta-isomer and the para-isomer of Reactive Yellow 095.
The presence of sulphonate groups make both dyes highly water soluble and therefore less critical for human health and environmental issues. Based on their chemical similarity, similar properties are expected in both humans and the environment.
2. SOURCE AND TARGET CHEMICAL(S)
Source: Reactive Yellow 095 meta/para (CAS# --- / EC# 944-218-2)
Target: Reactive Yellow 095 meta (CAS# 84045-63-6 / EC# 281-865-3)

- Validity criteria fulfilled:

- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- Biodegradation of the test substance after 28 days was 0%.
- Executive summary:
A key study was performed to determine the percent biodegradation of the source substance. Inherent biodegradability was determined in a 28 days test according to OECD TG 302B. The test substance was tested in a concentration of 150 mg/l. The reference substance was diethylene glycol. Based on the results of the study, biodegradation of the test substance after 28 days was 0 %.
In a second key study, the biochemical oxygen demand of the source substance is determined by measuring the dissolved oxygen concentration before and after 5 days incubation at 20°C in different test concentrations diluted in water saturated with dissolved oxygen and containing a seed of microorganisms. The test substance was tested in concentrations from about 6 to 800 mg/l. The reference substance D(+)-Glucose / L-Glutamic acid was tested in a concentration of 20 mg/l. The BOD5 of the source substance: 3 mg 02/g. The BOD5 of the reference substance is : 195,180, 200 mg O2/I.
In a third key study, the source substance 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 (according to DEV H 41-1, DEV1980). 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/I. The COD of the source substance is : 402 mg 02/g The COD of the reference substance is: 193 mg O2/I.
In four supporting studies, the BOD5 of the source substance was determined to be 0 mg O2/g. The COD of the source substance was determined to be 157 mg O2/g, 417 mg O2/g, 581 mg O2/g and 771 mg O2/g, respectively.
Based on these results the corresponding BOD5/COD quotient is equivalent or close to zero, so no biodegradation is expected for the source substance and for the structurally related target substance as well.

Description of key information
The substance is a reactive dye and as such the substance should not be considered to be biodegradable at all. This is confirmed by the studies performed on the source substance.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- freshwater
