Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
No toxicity data of sufficient quality for aquatic organisms are available for ammonium metatungstate (target substance). However, toxicity to aquatic organisms data are available for ammonium paratungstate and sodium tungstate (source substances), which are used in the weight-of-evidence approach for read-across.
Due to similar or lower transformation/dissolution results for ammonium metatungstate (the target substance) than ammonium paratungstate, sodium tungstate and sodium metatungstate (the source substances), the resulting toxicity potential is expected to be similar or lower, so read-across is appropriate. In addition, read-across is justified because the classification and labelling is the same or less severe for the target substance and the PBT/vPvB profile is the same. Finally, the dose descriptors are, or are expected to be, sufficiently similar or higher for the target substance, and read-across to the source chemicals are adequately protective. For more details, refer to the read-across category approach description in the Category section of this IUCLID submission or Annex 3 of the CSR.
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.
