Description of key information

Short-term toxicity:

ECOSAR 1.11: Green Algae: EC50 (96h): 0.021 mg/L

 

Long-term toxicity:

Indicated results for chronic toxicity are "Chronic values" as obtained from ECOSAR 1.11

ECOSAR 1.11: Green Algae: ChV: 0.010 mg/L

Key value for chemical safety assessment

EC50 for freshwater algae:
0.021 mg/L
EC10 or NOEC for freshwater algae:
0.01 mg/L

Additional information

NOEC could be estimated to around 0.007 mg/L (ChV/√2) as indicated in Practical Guide 5 - How to use and report (Q)SARs 3.0 (March 2016)

Intermediate substance is estimated to be very toxic to aquatic algae with long lasting effects.
