Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Three acute toxicity results on three freshwater trophic levels (algae, aquatic invertebrates and fish) and two chronic toxicity results from two freshwater trophic levels (algae and aquatic invertebrates) are available. In all studies no adverse effects were observed up to the maximum tested concentration and consequently no hazard was identified for the aquatic environment.
There is no data suggesting that the substance may exert adverse effects on soil and sediment-dwelling organisms. In addition, all the available experimental data support the fact that cC6O4 ammonium salt is not bioaccumulative both in the aquatic and terrestrial organisms and therefore the secondary poisoning is unlikely to occur.
The environmental risk assessment would therefore not be required for cC6O4 ammonium salt and it is conducted just according to a precautionary approach in order to demonstrate the lack of effects on the environment due to the use of the substance.
Conclusion on classification
The criteria for the environmental hazard classification according to Regulation EC 1272/2008 are not met as the substance was observed to not exert toxic effect on aquatic organisms in the available ecotoxicological studies.
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).
