Description of key information

The median effective concentration (EC50) was defined as the concentration, calculated from the data obtained, resulting in immobilization of 50% of the daphnia in the time period specified.
 
The values obtained (and their 95% confidence limits) were:
24 h EC50: 200 (140 – 390) mg/L
48 h EC50 26 (23 – 30) mg/L

Key value for chemical safety assessment

Additional information

The 24 and 48 hour median effective concentrations oft he test item tot he freshwater crustacean Daphnia magna (<24 hours old) were determined und static test conditions at a temperature of 20 +/- 1 °C.

 

The median effective concentration (EC50) was defined as the concentration, calculated from the data obtained, resulting in immobilization of 50% of the daphnia in the time period specified.

 

The values obtained (and their 95% confidence limits) were:

24 h EC50: 200 (140 – 390) mg/L

48 h EC50 26 (23 – 30) mg/L

 

The measured concentrations of the test material at the start and finish of the test ranged from86% to 100% of the nominal values.
