TOPP is a UVCB substance. Standard tests for this endpoint are intended for single substances and are not appropriate for establishing the risk assessment of this complex substance. For the purpose of risk assessment, soil PNECs for constituent blocks have been derived using aquatic PNECs in conjunction with the equilibrium partitioning method (EqP).
