Hazard for predators

Secondary poisoning

Hazard assessment conclusion:
no potential for bioaccumulation

Additional information

The most sensitive species is Daphnia with an EC50 = 3.9 mg/L for short-term effects and NOEC = 3.6 mg/L for long-term effects.


For the others species, not toxicity was found.

Conclusion on classification

The substance is not “readily biodegradable” and not “inherent biodegradable”.


The substance has no bioaccumulation potential.


The acutely toxic effects on organisms like fish and algae, are conclusive but not sufficient for classification. Short-term effects on Daphnia were observed. There were no long-term effects on Daphnia at <= 1 mg/L.
