Description of key information
Additional information
With a measured mean Kd of 43664 L/kg C36 -alkylenediamines has a strong sorption to soil.The PNEC soil is calculated using the equilibrium paritioning method as no short or long-term terrestrial test data is available for C36 -alkylenediamines.
In the absence of measured data the PNECsoilwas calculated using the equilibrium partitioning method (EPM). According to the TGD this method uses the PNECaquaticand the soil/water partitioning coefficient as inputs.
The PNECsoil is then calculated using the equations detailed in the TGD:
PNECsoil= Ksoil-water* PNECaquatic dissolved* 1000 * 1 / RHOsoil
Where:
PNECaquatic dissolved = 0.234 µg/L
Ksoil-water= 65496 m3. m-3
RHOsoil = 1700 kg. m-3(TGD, equ. 18)
PNECsoil-EPM =9.0 mg/kg ww = 10.18 mg/kg dw
PNECsoil-EPM= 0.90 mg/kg ww including the correction for exposure via ingestion= 1.02 mg/kg dw
