Additional information

In a GLP study the acute toxicity to Daphnia magna was investigated according to OECD guideline 202 'Daphnia sp, acute immobilisation test' under semi-static test conditions. All validity criteria were fulfilled.

The study resulted in a NOEC of 4.47 mg/L and in an EC50 of 6.784 mg/L (95% CL = 5.514 – 8.327).
