Description of key information

Daphnia magna was exposed under static conditions for 48 hours to one concentration (100 mg/L) of the dried test substance. No toxic effect was observed. An EC0 of > 97.6 mg/L was calculated.

Key value for chemical safety assessment

Additional information

In order to test acute toxicity to invertebrates of the dried substance, Daphnia magna was esposed to the test solution of one nominal concentration of the test substance (100 mg/L) and blank control solution for a period of 48 hours under static conditions. Mobility and visible abnormalities were recorded at 24 and 48 hours. The measured concentrations confirmed that deviation from the nominal concentrations was less than 20 % (measured concentrations were in the range of 94.4 - 100.8 % of nominal concentrations). No toxic effect and abnormal behavior were observed. An EC0 of > 97.6 mg/L was calculated. This toxicity study is classified as acceptable and satisfies the guideline requirements for the acute Daphnia study.
