Description of key information

Freshwater and marine sediment PNEC value of 12.27 and 13.09 mg/kg dw were determined with the equilibrium partitioning method.

Key value for chemical safety assessment

Additional information

A sediment PNEC value of12.27 mg/kg dwwas determined with the equilibrium partitioning method as follows:

PNECsediment freshwater = Ksusp-water * PNECaquatic * 1000 * 1 / RHOsusp (ECHA guidance document R10, May, 2008).

The sediment marine water PNEC value of13.09 mg/kg dwwas determined with the equilibrium partitioning method using the equation:

PNECsediment marine water = Ksusp-water* PNECmarinewater * 1000 * 1 / RHOsusp (ECHA guidance document R10, May, 2008).
