- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The BOD5 of FAT 21036/B is 20 mg O2/g test mat.
- Executive summary:
The biochemical oxygen demand of FAT 21036/B 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 that contains a seed of microorganisms. This test was conducted in accordance with CIBA internal guideline A-15.
Based on the findings of the study, the BOD5 of FAT 21036/B was found to be 20 mg O2/g test mat. In another study, the COD of FAT 20136/B was found to be 1230 mg O2/g, the resulting BOD5/COD ratio is 0.02 suggesting the test substance is not biodegradable.

- Executive summary:
The chemical oxygen demand of FAT 21036/B was determined by measuring the equivalent amount of oxygen in terms of amount of potassium dichromate that is consumed by reacting with the oxidizable components of 1 g of sample material dissolved in 1-liter water. This test was conducted according to CIBA internal guideline A-22.
Based on the findings of the study, the COD of FAT 21036/B was found to be 1230 mg O2/g test mat. In another test, the BOD5 of FAT 21036/B was found to be 20 mg O2/g test material. The resulting BOD5/COD ratio was found to be 0.02 indicating that the substance is not biodegradable.

Additional information
The biological elimination of FAT 21036/B is found to be 22 % i a Zahn-Wellens test. The chemicxal oxygen demand of FAT 21036/B was found to be 1230 mg O2/g test material whereas the biological oxygen demand was found to be 20 mg O2/g test material.
Several other key studies showed the following results:
COD of 615.50 mg O2/g test material.
BOD5 of 0 mg O2/g test material.
The relevant BOD5/COD quotient is <0.5, therefore, the substance is not indicative of rapid degradation. Taking the data from key study and supporting studies into account, the test substance Acid Blue 225 is considered to be not biodegradable.
