Description of key information

The constituents of this UVCB substance do not meet the criteria for bioaccumulation accoding to REACH.

Key value for chemical safety assessment

BCF (aquatic species):
38.9 dimensionless

Additional information

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 according to REACH. A QSAR BCF value of 38.9 (dimensionless) made available for the analogue substance EC 259 -048 -8 was included to permit calculation of exposure concentrations during risk assessment using Chesar 3.
