Description of key information

1) Key: An acute toxicity test with invertebrates (Daphnia magna) (48h) (K1) (OECD 202 & GLP) resulted in an EC50 (immobility) > 1.8 mg/L and a NOEC = 0.36 mg/L (both represent measured values).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
1.8 mg/L

Additional information

The available short-term Daphnia study (Putt, 1995) resulted in an unbound EC50 value (immobility, 48h), however a NOEC of 0.36 mg/L was established for D.magna after 48h of exposure. A Water Accommodated Fraction (WAF) was used to expose the organisms to chemical concentrations equal or above the water solubility. As this test was performed according to the internationally accepted guidelines, the results were found suitable for risk assessment and classification purposes.
