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
