Description of key information

NOEC (48 h): 32 mg/L

20-25% immobilisation was observed at target concentrations of 56 and 100 mg/L.

Key value for chemical safety assessment

Additional information

In an acute toxicity test with Daphnia magna (48 hours, flow through, analytical confirmation of test item concentrations) the following results were obtained:

NOEC (48 h): 32 mg/L

EC50 (48 h): >100 mg/L

20-25% immobilisation was observed at target concentrations of 56 and 100 mg/L.

The study procedures were based on the ISO International Standard 6341, 1996. In addition, the test methods and validity criteria of the EEC directive 92/69, Part C.2, 1992 and the OECD guideline No. 202, 2004 were met.
