Description of key information

- LC50 (48 h) values for Pimephales promelas ca. 20000-40000 mg/l (US EPA protocols) (test material: SCP effluent)

Key value for chemical safety assessment

Additional information

There was only one available study concerning short-term toxicity to fish, and the test material was not SCP liquor but SCP effluent (from the clarifier outlet). Therefore the results are only indicative regarding SCP liquor. The LC50 (48 h) values for P. promelas varied between ca. 20000-40000 mg/l.
