Short-term toxicity to aquatic invertebrates

Description of key information
Daphnia Magna, Acute toxicity, Ec50, 48h > 10 mg/l (equal to EC0, precipiation occured)
Key value for chemical safety assessment
Additional information
One acute toxicity study on aquatic invertebrates, namely Daphnia Magna, is available for the analogue substance (Huntsman, 1993). During the experiment precipitation of the test item in the test medium occured and at the solubility limit of the test item under the experimental conditions the EC50, 48h is > 10 mg/l, which correspond to EC0 since no immobilisation was observed.
Based on the read across considerations the same results apply to Acid Black 164.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
