Description of key information

effect values for average specific growth rates of Pseudokirchneriella subcapitata, 0-72 h, based on loading rates (OECD 201, EU C.3):
EL50: >100 mg/L, NOELR: 31 mg/L, EC10: 40 mg/L

Key value for chemical safety assessment

Additional information

EL50 for freshwater algae: > 100 mg/L
NOELR for freshwater algae: 31 mg/L

The test results indicate that the test material is not inhibitory to growth of algae up to the limits of its water solubility and a NOEC and thus a PNEC cannot be determined.
