Hazard for predators

Secondary poisoning

Hazard assessment conclusion:

Additional information

The PNECs aqua were derived from the most sensitive test for the aquatic compartment, the short-term toxicity to fish and invertebrates. For other compartments, the PNECs are based on equilibrium partitioning.

Conclusion on classification

The short-term LC50 or EC50 values are above 0.05 mg/l for fish, 0.05 mg/l for daphnia and 0.08 mg/l for algae.

In addition, the substance is not readily biodegradable, and has a log Kow of 3.4.

According to CLP(Directive 1272/2008/EC), no classification for the aquatic hazard should be taken.
