Additional information

All calculations of PNECs were based on the standard approach as described in the REACH guidance with the water solubility as starting point for the PNECaqua. This approach is considered to represent a worst case, as an alternative approach based on the NOEC in daphnia of 0.08 mg/L (Environment Japan, 1998, Klimisch 4) with an assessment factor of 100 would lead to a PNEC of 0.8 ug/L (slightly above the value used for risk assessment).

Conclusion on classification

No classification for environmental toxicity is considered necessary
