Additional information

Three studies on acute toxicity to aquatic species are available for the analogue substance with the following values: LC50,96h = 11.13 mg/l (fish); EC50,24h = 617 mg/l (dafnia) and EC50,72h,biomass = 2.9 mg/l (algae). A long term toxicity to fish was also performed following OECD 204 with a 14 -day exposure of fish with the following value NOEC = 0.876 mg/l.

based on the read across considerations the same applies to Acid Black 233:1
