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 0.307 mg/L for fish, 2.45 mg/L for algae and 0.953 mg/L for daphnia. Although the water solubility of the sample is less than 0.248 mg/L at 20°C, it has a significant inhibitory effects for growth rate and yield at test item concentrations of 0.298 mg/L (nominal) and 0.0563 mg/L(actual) and above. In addition, the substance is not readily biodegradable, and has a logKow of 5.18. According to CLP (Directive 1272/2008/EC), the aquatic hazard of substance is classified as Acute Category 1 and Chronic Category 1.
