Description of key information

The test item was not found to be acutely toxic to algae (Pseudokirchneriella subcapitata) when dispersed in medium at a nominal concentration of 100 mg/L. Hence, the 72 hour EC50 (biomass, growth rate, yield) as well as the NOEC were determined to be > 100 mg/l and 100 mg/l respectively.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
32 mg/L
