Additional information
A limit test was performed on Acid Black 210 showing a NOEC > 120 mg/l. The study has been presented to ECHA in the framework of a notification and the summary received is lacking of many information.
Another study (Synthesia, 1996) was performed on Acid Black 210 potassium salt testing different concentrations that allowed the extrapolation of a more realistic values for LC50, equal to 1890 mg/l and LC0, >1600 mg/l.
The results of the two studies are consistent and STAHL results have been chosen for CSA as performed on the registered substance and more conservative.
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).
