Description of key information

Algae Growth Inhibition Test, OECD 201, EU C.3:
EC50(72h) >15.94 mg/L, based on growth rates (14.13 mg/L, based on yield)
NOEC(72) >= 17.55 mg/L, based on growth rates (14.13 mg/L, based on yield)

Key value for chemical safety assessment

EC50 for freshwater algae:
15.94 mg/L
EC10 or NOEC for freshwater algae:
17.55 mg/L

Additional information

In an algae growth inhibition test with the freshwater green algae Pseudokirchneriella subcapitata the EC50(72h) was greater than 15.94 mg/L based on growth rates and 14.13 mg/L based on the yield.
