- Executive summary:
The QSAR predicted 15-h EL50 (inhibition of total respiration) and 15-h EL10 (inhibition of total respiration) of the UVCB substance for Activated Sludge were 106 and 9.93 mg/L respectively. The model used for the predictions was the PETROTOX v4.0 model. PETROTOX is a well-documented and peer reviewed model that is widely used across the chemicals industry. This substance fits within the criteria of the model and there are no reservations about the validity of the model runs. It is expected that this data is reliable with restrictions.
