Additional information

According to Guidance on information requirements and chemical safety assessment R10.5 the PNEC sediment was calculated with the Equilibrium partitioning method.

The log Kow of 2.7 indicates a minor risk of accumulation in sediment. According to the model calculation with Mackay (see 5.4.3.) sediment is not the main target for the distribution of Dodecane-12-lactam in the environment. Only 5.9% of the total amount released to the environment end up in the sediment, more than 80% will remain in the hydrosphere. Furthermore the substance is readily biodegradable within the 10 day-window. The longterm exposure of sediments is therefore unlikely.
