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]

0.0128

RHOsusp

bulk density of wet suspended matter

[kg.m-3]

1150

Ksusp water

partition coefficient suspended matter water

[m3.m-3]

1.27

PNECsed

Predicted No Effect Concentration in sediment

[mg.kg-1of wet sediment]

 0.1413

 

Dry weight: 0.1413 * 4.6 = 0.065

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

 

Kpsusp= Focsusp*Koc

The value of Ksusp-water of 0.979 is consistent with the calculated value with EUSES 2.1.1.

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 = 0.1413*0.1 = 0.001413 mg/kg.

Dry weight = 0.001413* 4.6 = 0.0065

PNEC soil using Equilibrium Partitioning Method:

The following formula is applied:

PNECsoil= Ksoil-water*PNECwater*1000/RHOsoil

Where:

ECwater

Predicted No Effect Concentration in water

[mg.l-1]

0.0128

RHOsoil

bulk density of soil

[kg.m-3]

1700

Ksoil water

partition coefficient soil water

[m3.m-3]

0.65

PNECsoil

Predicted No Effect Concentration in soil

[mg.kg-1]

0.00489

  

Dry weight = 0.00489*1.13 = 0.0055

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 results of the eco-tox tests, the substance needs to be classified as Aq. Chronic 3, H412 under Regulation 1272/2008 (CLP) since the tested item shows toxicity on daphnia with a EC50 (48h) = 31.6 mg/l and on algae with a IC50 (72h) = 12.8 mg/l
