The 5-day biological oxygen demand (BOD5) is 0 mg O2/mg test substance. The theoretical oxygen demand (TOD) is 0.384 mg O2/mg test substance. Additionally, two QSAR calculations are available showing that the teat substance is not readily biodegradable.

Moreover, the pigment is practically insoluble and therefore considered to be essentially not bioavailable. Due to the large molecular size, cellular uptake of the pigment is unlikely. Hence intracellular biodegradation, which is the main degradation route of bacteria, is probably low. Therefore, in overall conclusion, it is likely that the test substance is persistent in the environment.
