Additional information

Aquatic bioaccumulation

Based on the weight of evidence from read-across to structurally similar ZDDP substances with BCF data in fish (from Japanese MITI data, US EPA database, CAESAR database), measured Log Kow data and QSAR predictions, this substance is expected to have low bioaccumulation potential. This substance does not meet the criteria of concern for bioaccumulation based on information available.

Terrestrial bioaccumulation

Data on terrestrial bioaccumulation are not considered to be required for the substance. In accordance with the REACH legislation, the test does not need to be conducted if direct and indirect exposure to the terrestrial compartment is unlikely. In addition, the results of the CSR for this substance and the PEC/PNEC ratios for the local and regional terrestrial compartment indicate no risk. ECHA Chapter R.7B guidance states that if the PEC/PNEC ratio is below 1, then no risk for the compartment is indicated and there is no need to perform further tests. Furthermore, this substance does not meet the B or vB criteria and it is not considered to be a PBT substance.
