Description of key information
Aquatic Chronic 3 (H412), according to the CLP Regulation (EC) No 1272/2008.
Additional information
The following data was obtained for Similar Substance 01 on Brachydanio rerio, Daphnia magna and Desmodesmus subspicatus and Pseudokirchneriella subcapitata, respectively. It is expected that the Target Substance will present similar effect levels to these aquatic organisms. Justification for the use of a read-across approach is provided in Section 13 of IUCLID.
Acid Blue 134 has a log Kow lower than -2, indicating a low potential for bioaccumulation and it is expected to be not rapidly degradable.
According to the CLP Regulation (EC) No 1272/2008, acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50; these species cover a range of trophic levels and taxa and are considered as surrogate for all aquatic organisms.
Data are available for fish (Brachydanio rerio), Daphnia magna and algae (Desmodesmus subspicatus and Pseudokirchneriella subcapitata).
The outcomes of the tests performed on the three trophic levels suggest that algae is the most sensitive species, thus the classification should be based on the related data. According to the CLP Regulation (EC) No 1272/2008 criteria for the identification of the classification categories for hazardous to the aquatic environment, studies about short-term toxicity to invertebrates and toxicity to aquatic algae fixed the short-term effect level in the range of 10 -100 mg/l.
In conclusion, the substance is classified as Aquatic Chronic 3 (H412), according to the CLP Regulation (EC) No 1272/2008.
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).
