Description of key information

In a static immobilization test, young Daphnia magna (< 24 h old) were exposed to the test item for 48 hours according to OECD 202 (1984). A limit test with a single concentration of 100 mg/L was performed. The EC0 and EC50 were determined to be greater than 100 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

In a static immobilization test, young Daphnia magna (< 24 h old) were exposed to the test item for 48 hours according to OECD 202 (1984). A limit test with a single concentration of 100 mg/L was performed. The measured concentrations were determined to be 100 - 101 mg/L. The study encompassed 6 treatment groups (5 dose rates of the test item, control) each containing 20 individuals. The mobility of the Daphnia was determined in a static 48-hour test by visual observation after 3, 6, 24 and 48 hours. The samples collected at start and after each sampling time were analyzed via capillary electrophoresis with indirect UV-detection. No results with a reference substance were performed and the test results not allowed statistical evaluation of the data. The EC0 and EC50 were determined to be greater than 100 mg/L.
