Description of key information
PNEC for bethic organisms is calculated applying the equilibrium partitioning method using a Koc of 21 L/kg)
Key value for chemical safety assessment
Additional information
PNEC sediment-freshwater
In the absence of measured data the PNECsedcan be provisionally calculated using the equilibrium partitioning method (EPM). According to the TGD this method uses the PNECaquaticand the sediment/water partitioning coefficient as inputs.
The PNECsedis calculated using the equations detailed in the TGD:
PNECsed = Ksusp-water* PNECaquatic* 1000 * 1 / RHOsusp
Where:
PNECaquatic = 0.095 mg/L SCN- (0.125 mg/L NH4SCN)
Ksusp-water = 1.425 m3.m-3
Koc = 21 L/kg
RHOsusp = 1150 kg.m-3 (TGD, equ. 18)
Conversion factor from mg/kg/ww to mg/kg/dw = 4.607
PNECsed-EPM = 0.1177 mg/kg ww = 0.5423 mg/kg dw
