Description of key information
EC50 (48h): > 150 mg/L
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 150 mg/L
Additional information
A limit test on Daphnia Magna has been performed (Stahl, 1996), showing no mortality at the tested concentration of 180 mg/L. Since the sample concentration is 83% of the nominal concentration, the EC50 has been set at 150 mg/L
