Description of key information

Short-term toxicity: EC50 (48 h) = 36 mg/L (OECD 202)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
36.6 mg/L

Additional information

In a test performed according to OECD 202, Daphnia magna were exposed to the nominal loading rates of 4.6, 10, 22, 46 and 100 mg/L test substance in 4 replicates of each 5 animals. Although at high concentrations the water solubility seemed to be exceeded, the EC50(48 h) was estimated to be 36.6 mg/L based on observed immobilization at lower concentrations.
