Additional information
Pseudokirchneriella subspicata were exposed for 72 h in an OECD 201 test towards the test substance. The EC50 for growth rate was determined to be 0.00221 mg/l based on mean measure concentrations and 0.0322 mg/l based on mean measured concentration at the start of exposure. The NOEC for growth rate was determined to be 0.00143 mg/l based on mean measure concentrations and 0.00466 mg/l based on mean measured concentration at the start of exposure.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
