EC50 (48 h) > 100 mg/L (BASF AG, 1993)

Key value for chemical safety assessment

Additional information

The 48 -hour acute toxicity of the test substance to Daphnia magna STRAUS was studied under static conditions (BASF AG, 1993). Daphnids were exposed to control and test substance at nominal concentrations of 0, 12.5, 25, 50 and 100 mg/L for 48 hours. Immobilisation and sublethal effects were observed at 0, 3, 6, 24 and 48 hours. None of the animals showed any adverse effects or immobilisation at any of the concentrations tested. The 48-hour EC50 was above 100 mg/L.
