Description of key information

The 72 hour EC50 (growth rate) was reported as >1000 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L

Additional information

Two data entries were made for the toxicity to aquatic algae and both appeared to be of acceptable quality. One reported a 72 -hour EC50 based on growth rate at >1000 mg/L and the other reported a 72 -hour EC50 based on biomass at 494 mg/L. Since the 72 -hour EC50 based on growth rate is the scientifically preferred endpoint (according to OECD 201), this was selected as the key study and endpoint.
