Additional information

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

Conclusion on classification

The short-term LC50 or EC50 values are > 0.385 mg/L for fish, 244 µg/L for algae and > 0.432 mg/L for daphnia. In algae growth inhibition test, the NOEC is 88 µg/L (< water solubilty 0.1 mg/L) and there is inhibitory effect to algae.

In addition, the substance is not biodegradable, and has a log Kow of 4.24.

According to CLP (Directive 1272/2008/EC), the aquatic hazard of substance is classified as Aquatic Acute 1 and Aquatic Chronic 1.
