Description of key information

A toxicity studies with Pseudokirchnerella subcapitata is available which was run to GLP. In the key study (Migchielsen, 2010) with Pseudokirchnerella subcapitata, the EC50 (72 h) was greater than 30.5 mg/L,  EC10 (72h) was 6.5 mg/L and NOEC was 0.09 mg/L based on measured concentrations.

Key value for chemical safety assessment

EC50 for freshwater algae:
30.5 mg/L
EC10 or NOEC for freshwater algae:
6.5 mg/L
