Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
20 mg/L

Additional information

Two short-term toxicity tests on aquatic invertebrates are available for the test substance. The toxicity of the test substance to daphnia magna has been determined in an acute toxicity test for daphnia according to EU method 84/449/EEC C.2. The test (93-542-FGO) revealed an EC50 value of 20 mg/L after 48 h of exposure and 54 mg/L after 24 h. The EC50 after 24 h is determined to be 54 mg/L. In addition, the toxicity on Daphnia magna has been tested in a toxicity test according to guideline DIN 38412 part 11. The LC50 has been derived to be 28.1 mg/L after 24 h.
