Additional information

In the absence of sediment toxicity data, the PNEC sediment is calculated using the equilibrium partitioning method (EPM) as follows (in accordance with ECHA Guidance on Information Requirements, PartB):

 

PNECsediment =(0.783 + 0.0217 x Koc) x PNEC water.

 

Estimated Koc forTCPP=289.1 - 1604 L/kg (by following a precautionary approach, the lowest estimated Koc value of 289.1 L/kg will be used in the calculation); PNEC water =0.42 mg/L

 

Therefore, PNECsediment= 2.96 mg/kg is calculated forTCPP.
