Description of key information

effect values for growth rates of Pseudokirchneriella subcapitata, 0-72 h (OECD 201, EU C.3):

EC50: 13-32 mg/L, NOEC: 3-8 mg/L

Key value for chemical safety assessment

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

Additional information

Two comparable studies performed with green algae are available. The results of both studies are in the same range. Methanol was used to prepare the test solutions in the one study. Key values for the chemical safety assessment are taken from the study which did not use solvent.
