Description of key information

Additional information

No toxicity to terrestrial organisms data of sufficient quality are available for Ammonium metatungstate (target substance). However, toxicity to terrestrial organisms data are available for sodium tungstate (source substance), which were used in the weight-of-evidence approach for read-across.

 

Due to similar or lower transformation/dissolution results for ammonium metatungstate (target substance) than sodium tungstate (source substance), the resulting toxicity potential is expected to be similar or lower, so read-across is appropriate. In addition, read-across is justified because the PBT/vPvB profile is the same. Finally, the dose descriptors are expected to be, sufficiently similar or higher for the target substance, and read-across to the source substance is 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.
