LC50, 96h, OECD 203, Danio Rerio, static, > 500 mg/l

EC50, 72h, OECD 201 with deviations for coloured substances > 320 mg/l

EC50, 48h, OECD 202, Daphnia Magna, static = 37.2 mg/l

OECD 211, Daphnia Magna, semi-static, NOEC > 30 mg/l

Additional information

The analogue substance was tested for acute toxicity to fish, aquatic invertebrates (short and long term toxicity) and toxicity to aquatic algae (NONS dossier, 1988).

In the acute toxicity test to fish the substance showed a LC50, 96h >500 mg/l and for the aquatic algae EC50, 72h >320 mg/l.

The acute toxicity to aquatic invertebrates showed a EC50, 48h = 37.2 mg/l, while the long term test resulted with a NOEC (21days) > 30 mg/l.

Based on the read across considerations same results apply to the test item
