Additional information

Conclusion on classification

Based on the available information:

-Short-term toxicity to fish:

96 hour LC50 = 0.3 mg/l

-Short-term toxicity to daphnia:

48 hour EC50 = 0.4 mg/l

-Toxicity to aquatic algae:

72 hour ErC50 = 4.9 mg/l

NOEC based on the area under the growth curves = 1.6 mg/l

NOEC based on the average specific growth rate = 2.8 mg/l

and since the substance has a log Pow greater than 4 and it is not readily biodegradable, it is concluded that the substance is classified as Hazardous to the aquatic environment, Acute Category 1 and Chronic Category 1.
