Description of key information

Immobilisation of Daphnia magna (OECD guideline No. 202, 48 hours exposure at 20°C) (Biermann, 2009). Test without pH-adjustment (pH of test medium below pH 6.0): EC50 (48h) = 67 mg/l Key value for chemical safety assessment: Test with pH-adjustment (measured pH=7.5 at 48 hours): EC50 (48h) higher than 1000 mg/l.

Key value for chemical safety assessment

Additional information

Any tests without pH neutralisation revealed effects in treatments with pH values below 6 (in Biermann, (2009) and in Toray (1997).
