Additional information
PNEC sediment using Equilibrium Partitioning Method:
The following formula is applied:
PNECsed= Ksusp-water p*PNECwater*1000/RHOsus
Where:
PNECwater |
Predicted No Effect Concentration in water |
[mg.l-1] |
0.1 |
RHOsusp |
bulk density of wet suspended matter |
[kg.m-3] |
1150 |
Ksusp water |
partition coefficient suspended matter water |
[m3.m-3] |
0.979 |
PNECsed |
Predicted No Effect Concentration in sediment |
[mg.kg-1of wet sediment] |
0.085 |
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. The tool gives 0.874 putting a Koc QSAR for organic acids 3.16 for non hydrophobic substances
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 = 0.085*0.1 = 0.0085 mg/kg
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] |
0.1 |
RHOsoil |
bulk density of soil |
[kg.m-3] |
1700 |
Ksoil water |
partition coefficient soil water |
[m3.m-3] |
0.295 |
PNECsoil |
Predicted No Effect Concentration in soil |
[mg.kg-1] |
0.0174 |
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
According to EC 1972/2008 and related amendment II EC 286/2011, the substance has to be classified for acute aquatic toxicity if 96 hr LC50 (for fish)≤ 1 mg/l and/or 48 hr EC50 (for crustacea)≤ 1 mg/l and/or 72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l.
Since all the values are higher than the limit value for classification, the substance has not to be classified for acute and chronic aquatic toxicity.
