Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data on acute single-species toxicity tests resulting in high quality NOEC/L(E)C10 values (expressed as Co) for freshwater and marine fish (n= 12) are summarised in Table 2 of the WHO CICAD document, 2006 (see attached document).
One short-term toxicity test on the effects of cobalt chloride to Oncorhynchus mykiss conducted according to methods comparable to guidelines was chosen here, as a representative test yielding the lowest effect concentration for the evaluation of short-term effects on fish. Other short-term toxicity data for fish exists. However, the LC50s were as well in the same range, so they were not reported here.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.
