Additional information

PNEC sediment using Equilibrium Partitioning Method:

The following formula is applied:

PNECsed= Ksusp-waterp*PNECwater*1000/RHOsus

Where:

PNECwater

Predicted No Effect Concentration in water

[mg.l-1]

0,00026

RHOsusp

bulk density of wet suspended matter

[kg.m-3]

1150

Ksusp water

partition coefficient suspended matter water

[m3.m-3]

63.1

PNECsed

Predicted No Effect Concentration in sediment

[mg.kg-1of wet sediment]

0.0143

 

Ksusp water= Fwatersusp+ Fsolidsusp*Kpsusp/1000*RHOsolid

 

Kpsusp= Focsusp*Koc

 

PNEC marine sediment using Equilibrium Partitioning Method:

Being marine PNEC usually derived by freshwater PNEC with an adding assessment factor of 10, consequently the marine sediment PNEC can be directly derived from PNEC sediment with an assessment factor of 10.

Therefore PNEC marine sediments = 0,00023*0,1 = 0,000023 mg/kg

 

PNEC soil using Equilibrium Partitioning Method:

The following formula is applied:

PNECsoil= Ksoil-water*PNECwater*1000/RHOsoil

Where:

PNECwater

Predicted No Effect Concentration in water

[mg.l-1]

0.00026

RHOsoil

bulk density of soil

[kg.m-3]

1701

Ksoil water

partition coefficient soil water

[m3.m-3]

74.8

PNECsoil

Predicted No Effect Concentration in soil

[mg.kg-1]

 0.0114

  

Ksoil water= Fairsoil*Kair-waterl+Fwatersoil+ Fsolidsoil*Kpsoil/1000*RHOsolid

Ksoil water= Fairsoil*Kair-waterl+Fwatersoil+ Fsolidsoil*Kpsoil/1000*RHOsolid

Kpsoil= Focsoil*Koc

Conclusion on classification

Based on the value of LC50, Daphnia, 48h equal to 0.26 mg/l and the biodegradation results, following the criteria of Directive 1272/2008 the substance is classified as Aquatic Acute 1 H400: Very toxic to aquatic life and Aquatic Chronic 1 H410: Very toxic to aquatic life with long lasting effects.
