Description of key information
EC50, 24h, Daphnia Magna = 209 mg/l
Key value for chemical safety assessment
Additional information
The analogue substance was tested for acute toxicity to aquatic invertebrates following EU Method C2 (NONS dossier, 1991). Under the experimental conditions the EC50, 24h is equal to 209 mg/l.
Based on the read across considerations same results apply to Direct Blue 267:1.
