Description of key information

The registered substance is highly volatile which complicates environmental testing. Therefore, a modeling framework is needed to account for the bioavailability of the substance to perform read-across and data gap filling. The TLM-EqP modeling has been validated as a suitable method for predicting effect values in sediment and soil organisms.


The TLM-EqP predicted effect values (28-days) for this substance were 29.84 mg/kg and 5.72 mg/kg sediment dw for short-term (LL50) and long-term effects (NOELR), respectively.

Key value for chemical safety assessment

Additional information

For the purpose of risk assessment, sediment PNECs for the constituent has been derived using aquatic PNECs in conjunction with the equilibrium partitioning method (EqP).
