Additional information

The PNECs aqua were derived from the water solubility of the substance (0.007 mg/L). For other compartments, the PNECs are calculated based on equilibrium partitioning method.

Conclusion on classification

The LC50 for fish is > 4.5 mg/L, the EC50 for daphnia is > 5.25 mg/L and the NOEC and EC50 for algae is > 100% saturated solution (water solubility = 0.007 mg/L).

According to CLP (Directive 1272/2008/EC), the aquatic hazard of substance is not classified.
