Additional information
The PNECs aqua were derived from the most sensitive test for the aquatic compartment, the short-term toxicity to fish. For other compartments, the PNECs are based on equilibrium partitioning.
Conclusion on classification
The short-term LC50 or EC50 values are 7.10 mg/L for fish, 11.96 mg/L for daphnia and 11.70 mg/L for algae.
In addition, the substance is not readily biodegradable, and has a log Kow of 2.7.
According to CLP (Directive 1272/2008/EC), the aquatic hazard of substance is classified as chronic category 2.
