Description of key information

A 48 hour aquatic invertebrate toxicity test was carried out according to EU Method C.2 and OECD Guideline 202 (Method: DIN 38412 L11, Acute Toxicity for Daphnia). Daphnia magna were exposed in a static test over 48-hours to nominal concentrations of 18, 32, 58, 100, 180, 320, 580 mg/L. The 48-hour median effect concentration (EC50) for immobility, based on measured concentrations of test item, was found to be 77 mg/L (95 % confidence limits of 65 and 91 mg/L). The NOEC (EC0) after 48 h was determined 32 mg/L. The lowest measured concentration at which 100 % immobilization occurred after 48 h was 180 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
77 mg/L
