Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
