Description of key information

EC50 (48h, Daphnia magna) > 100 mg/l (nominal)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

The following data was obtained for Similar Substance 01 on Daphnia magna. It is expected that the Target Substance will present similar effect levels to this aquatic organism. Justification for the use of a read-across approach is provided in Section 13 of IUCLID.

In order to test acute toxicity to invertebrates, Daphnia magna was exposed to five nominal concentrations of the test item (25, 35, 50, 71 and 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.

Based on immobilisation, the 48-hour EC50 value was found to be greater than 100 mg/L based on nominal concentrations.
