Additional information

Formula for the calculation of PNECsoil using the equilibrium partitioning approach:

PNEC(soil) = (Ksoil-water x PNEC(aqua) / RHOsoil) * 1000

PNEC(soil) Predicted No Effect Concentration in sediment [mg/kg, wet weight]

Ksoil-water partition coefficient sediment / water [0.439 m3/m3]

RHOsoil bulk density of soil matter [1700 kg/m3]

PNECaqua Predicted No Effect Concentration in water [as above]

Molecular weight used: 220.

Conclusion on classification

The very low toxicity of this substance to aquatic species coupled with its ready biodegradability mean that it does not meet the criteria for classification.
