Additional information

Suitability of the PNECSoil value of 1.01 mg/kg is comparable to the level obtained using the equilibrium partition method (EPM). Calculation as follows:

In accordance with the equation provided on page 73 of the illustrative example of a CSR produced by ECHA. PNECsoil = (0.01176 + (0.01765 x 20489) x PNECwater. Therefore, PNECsoil = (0.01176 + (0.01765 x 20489)) x 0.001 = 0.362 mg/kg wet weight = 0.362 mg/kg wet soil. Apply conversion factor of 1.13 for converting from wet soil to dry soil gives a PNECSoil of 0.409 mg/kg soil dw.

Conclusion on classification

Classification and labelling:  

On the basis of effects noted in fish and Daphnia, the substance is deemed to be classified according to Regulation (EC) No 1272/2008, 2nd ATP the substance is also classified as:

Aquatic Acute 1 and Chronic Category 1.

H400: Very toxic to aquatic life.

H410: Very Toxic to aquatic life with long lasting effects.
