No dermal acute toxicity data of sufficient quality are available for
tungsten trioxide (target substance). However, dermal acute toxicity
data are available for sodium tungstate (source substance), which are
used for read-across. Due to lower water solubility and lower toxicity
for the target substance compared to the source substance, the resulting
read-across from the source substance to the target substance is
appropriate as a conservative estimate of potential toxicity for this
endpoint. In addition, read-across is appropriate because the
classification and labelling is more protective for the source substance
than the target substance, the PBT/vPvB profile is the same, and the
dose descriptors are, or are expected to be, lower for the source
substance. For more details, refer to the read-across category approach
in the Category section of this IUCLID submission or Annex 3 of the CSR.
